Juicy Cowboy Butter Grilled Flank Steak (Garlic Herb Butter Steak Dinner Ready in 25 Minutes)
Ingredients
For the Steak
- 1½ to 2 pounds flank steak – the star of the recipe trimmed if needed
- 1 tablespoon olive oil – helps the seasoning stick and promotes better grill searing
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- 1 teaspoon smoked paprika – adds smoky depth and color
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
For the Cowboy Butter Sauce
- 6 tablespoons unsalted butter melted
- 4 garlic cloves finely minced
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh lemon juice
- 1 teaspoon lemon zest
- 1 tablespoon chopped fresh parsley
- 1 teaspoon chopped fresh chives
- ½ teaspoon crushed red pepper flakes optional for heat
- ½ teaspoon paprika
- ½ teaspoon salt
- ¼ teaspoon black pepper
Optional for Serving
- Extra chopped parsley
- Lemon wedges
- Grilled corn
- Roasted potatoes
- Rice or grilled vegetables
Instructions
- Prep the Steak: Take the flank steak out of the refrigerator 20 to 30 minutes before cooking so it cooks more evenly. Pat it dry, rub with olive oil, and season both sides with salt, black pepper, smoked paprika, garlic powder, and onion powder.
- Make the Cowboy Butter: In a small bowl, whisk together melted butter, garlic, Dijon mustard, lemon juice, lemon zest, parsley, chives, paprika, salt, black pepper, and red pepper flakes if using. Set aside and reserve a little for serving later.
- Preheat the Grill: Preheat your grill to medium-high heat (about 450°F). Lightly oil the grill grates to help prevent sticking and create a better sear.
- Grill the Steak: Place the steak on the hot grill and cook for 4 to 6 minutes per side, depending on thickness and preferred doneness. Brush lightly with cowboy butter during the final minute. For best results, use a meat thermometer: 125°F for rare, 130°F to 135°F for medium-rare, and 140°F to 145°F for medium.
- Let It Rest: Transfer the steak to a cutting board and let it rest for 8 to 10 minutes so the juices redistribute and the steak stays tender.
- Slice Against the Grain: Slice the steak thinly against the grain to shorten the muscle fibers and create more tender bites.
- Finish and Serve: Arrange the sliced steak on a platter, spoon the remaining cowboy butter over the top, garnish with fresh herbs and lemon wedges if desired, and serve hot.

Behind the Recipe
This recipe came together during one of those evenings when I wanted steak but didn’t want a complicated steakhouse-style dinner that involved marinades, fancy sauces, or a sink full of dishes afterward.
I had a flank steak in the fridge, fresh herbs on the counter, and butter sitting out ready for something good. I started building a sauce with garlic, lemon, mustard, herbs, and spices—something bold enough to stand up to grilled beef but still bright enough to make every bite exciting.
The moment I brushed that warm cowboy butter over the sliced steak, I knew I had landed on something special.
What makes this recipe different is that it gives you that rich buttery steakhouse flavor without feeling heavy. The lemon brightens everything. The herbs keep it fresh. The garlic gives it depth. And that little touch of spice makes every bite feel just a little addictive.
As a female home chef, I love recipes like this because they strike that perfect balance between easy and impressive. It’s the kind of meal that looks like you worked hard, but secretly comes together fast enough for a busy weeknight.
That’s my favorite kind of cooking.

Budget-Friendly Without Sacrificing Flavor
Why it matters: One of the things I always tell readers is that you don’t need the most expensive steak cut to make an unforgettable meal.

Ingredient Highlights for Cowboy Butter Grilled Flank Steak
Sometimes a recipe works because the ingredients simply show up.
And sometimes a recipe works because each ingredient has a very specific job.
That’s exactly what happens here. Every ingredient in this juicy grilled steak recipe brings something important to the table—whether it’s flavor, texture, richness, brightness, or that little finishing touch that makes the whole dish taste balanced and unforgettable.
Flank Steak
Why I use it: Flank steak is one of my favorite cuts for quick grilling because it cooks fast, delivers bold beefy flavor, and becomes beautifully tender when handled correctly. It may not get the same attention as ribeye or filet, but for an easy grilled steak dinner, it’s honestly one of the smartest choices.
What I especially love about flank steak is how well it absorbs seasoning and how beautifully it slices after resting. When cooked hot and fast, then cut thinly against the grain, it transforms into juicy tender steak that tastes far more expensive than it actually is.
It’s also a naturally leaner steak option compared to some premium cuts, making it a great choice for people who want a protein-rich dinner that still feels hearty and satisfying.
Butter
Why it matters: Butter is what gives cowboy butter its signature richness and steakhouse-style finish.
When melted, it becomes the base that carries all the garlic, herbs, Dijon, lemon, and spices over the steak, coating every slice with rich buttery flavor.
This isn’t just “butter on steak”—it’s what transforms a simple grilled flank steak recipe into something bold, glossy, flavorful, and deeply satisfying.
That warm buttery finish is one of the reasons this recipe tastes so luxurious.
Garlic
Why I never skip it: Garlic brings savory depth and bold flavor that makes cowboy butter incredibly crave-worthy.
Fresh garlic gives a stronger, brighter flavor than garlic powder and adds that unmistakable steakhouse aroma the moment it hits warm butter.
For me, garlic is one of those ingredients that quietly does a lot of heavy lifting. It deepens the flavor of the butter sauce and gives every bite that rich savory note that keeps people coming back for another slice.
Dijon Mustard
Why it works: Dijon mustard is one of those ingredients people often underestimate in steak sauces.
It doesn’t make the butter taste like mustard.
Instead, it adds tang, depth, balance, and complexity that cuts through the richness of the butter and helps all the flavors come together.
That slight sharpness keeps the sauce from feeling too heavy and gives it a more layered steakhouse flavor.
Lemon Juice and Lemon Zest
Why I love this addition: Rich buttery steak sauces need brightness, and lemon brings exactly that.
Fresh lemon juice cuts through the richness and keeps the sauce lively instead of overly heavy, while lemon zest adds fragrant citrus flavor that lifts everything beautifully.
This little touch makes a huge difference.
Without it, the sauce would still taste good.
With it, the whole recipe tastes brighter, fresher, and more balanced.
Fresh Herbs
Why they matter: Parsley and chives add freshness, color, and that herb-forward finish that makes cowboy butter taste vibrant and restaurant-worthy.
Herbs help balance the richness of butter and steak by adding brightness and freshness to every bite.
They also make the final dish feel lighter and more polished, especially when spooned over hot sliced steak right before serving.
Fresh herbs are one of those finishing touches that may seem simple, but they make the whole recipe feel elevated.
Smoked Paprika
Why I use it: Smoked paprika adds subtle warmth, gentle smokiness, and deeper flavor that pairs beautifully with grilled beef.
It helps reinforce that backyard BBQ flavor and adds complexity without overpowering the buttery garlic sauce.
I especially love using it in grilled steak recipes because it complements charred meat so naturally.
Olive Oil
Why it helps: A light coating of olive oil helps seasoning stick to the steak and encourages better searing on the grill.
It also helps promote those beautifully caramelized grill marks that make steak look and taste even better.
Crushed Red Pepper Flakes
Why I like the option: This ingredient is optional, but I love adding a little heat because it gives the butter a subtle kick that balances the richness and buttery flavor beautifully.
It doesn’t make the dish spicy unless you want it to—it just adds a little extra excitement in the background.
Salt and Black Pepper
Why they matter: These may seem basic, but seasoning is what brings steak to life.
Salt helps highlight the beef’s natural flavor, while black pepper adds mild warmth and depth that rounds everything out.
Simple ingredients, used properly, make a huge difference in a recipe like this.
According to the National Institutes of Health database, beef naturally provides protein, iron, zinc, and important nutrients that make it a satisfying part of a balanced meal when paired thoughtfully with vegetables and sides.

How to Make Cowboy Butter Grilled Flank Steak
One of my favorite things about this recipe is that it looks and tastes impressive, but the process is actually very simple. Once you understand how flank steak likes to cook, this becomes one of the easiest grilled steak dinners to master.
Step 1: Prep the Steak
Take the flank steak out of the refrigerator about 20 to 30 minutes before cooking.
Pat it dry with paper towels, then rub both sides with olive oil.
Season with salt, black pepper, smoked paprika, garlic powder, and onion powder.
Letting the steak sit briefly helps it cook more evenly.
Step 2: Make the Cowboy Butter
In a small bowl, combine melted butter, garlic, Dijon mustard, lemon juice, lemon zest, parsley, chives, paprika, salt, black pepper, and red pepper flakes if using.
Whisk until fully combined.
Set aside, but save a little extra for serving later.
Step 3: Preheat the Grill
Preheat your grill to medium-high heat, about 450°F.
Clean and oil the grates lightly to help prevent sticking.
A hot grill helps create that beautiful char while keeping the inside juicy.
Step 4: Grill the Steak
Place the seasoned steak directly on the hot grill.
Cook for about 4 to 6 minutes per side, depending on thickness and your desired doneness.
Brush lightly with some cowboy butter during the final minute of cooking.
Use an instant-read thermometer for best results:
- 125°F: Rare
- 130°F to 135°F: Medium-rare
- 140°F to 145°F: Medium
According to the Cleveland Clinic, using a meat thermometer is one of the best ways to cook meat accurately while preserving quality and safety: https://my.clevelandclinic.org/
Step 5: Let It Rest
Transfer the steak to a cutting board and let it rest for 8 to 10 minutes.
This is one of the most important steps because it helps juices redistribute through the meat.
Step 6: Slice Against the Grain
Locate the direction of the muscle fibers and slice thinly against the grain.
This shortens the muscle fibers and makes the steak much more tender.
Step 7: Finish and Serve
Arrange the sliced steak on a serving platter and spoon the remaining cowboy butter over the top.
Garnish with fresh herbs and lemon wedges if desired.
Serve hot and enjoy every buttery, juicy bite.
Cowboy Butter Grilled Flank Steak delivers smoky charred edges, juicy slices of beef, and a bold garlic herb butter finish that transforms a simple steak dinner into something unforgettable.

Sam’s Pro Tips for Perfect Cowboy Butter Grilled Flank Steak
1. Let the Steak Sit Before Grilling
Secret Tip: One of the easiest ways to get a juicy, evenly cooked grilled steak is to let it sit at room temperature for about 20 to 30 minutes before grilling. Cold steak straight from the refrigerator tends to cook unevenly, which can leave the outside overdone before the center reaches the perfect doneness. This small step helps the meat cook more consistently and gives you a more tender steak dinner with better texture from edge to center.
2. Pat the Steak Dry for Better Searing
Secret Tip: I always pat flank steak dry before adding oil and seasoning because surface moisture is the enemy of a good sear. A dry steak hits the grill and develops those flavorful charred edges and caramelized grill marks that make grilled beef taste so much better. If you want that steakhouse-style crust, don’t skip this simple prep step.
3. Season Generously but Evenly
Secret Tip: Flank steak has a bold beefy flavor, but it still needs proper seasoning to shine. I like to coat both sides evenly so every bite gets balanced flavor instead of having one bland side and one over-seasoned side. Seasoning evenly also helps build that rich grilled steak flavor before the cowboy butter ever touches the meat.
4. Don’t Skip the Resting Time
Secret Tip: I know it’s tempting to slice right away, especially when the steak smells incredible, but resting is one of the most important parts of cooking juicy steak. Letting it rest for 8 to 10 minutes gives the juices time to redistribute through the meat instead of spilling out onto the cutting board. That’s the difference between a juicy steak dinner and one that dries out too fast.
5. Slice Against the Grain Every Time
Secret Tip: This is probably the most important flank steak trick I can give you. Flank steak has long muscle fibers, and slicing against the grain shortens them so each bite feels tender instead of chewy. Even perfectly grilled steak can feel tough if you slice it the wrong way, so always take a second to look at the grain before cutting.
6. Save Some Cowboy Butter for Serving
Secret Tip: I always brush a little garlic herb butter on the steak while it grills, but I never use it all. Spooning fresh cowboy butter over sliced steak right before serving creates a glossy, buttery finish and gives you that bold steakhouse flavor people remember. It also keeps the steak moist and adds a brighter finish because the fresh herbs and lemon stay vibrant.
7. Use a Meat Thermometer Instead of Guessing
Secret Tip: Flank steak cooks fast, and even an extra minute or two can push it from juicy to overcooked. I always use an instant-read thermometer because it takes the guesswork out of grilling. According to the USDA, using a food thermometer is one of the best ways to cook meat accurately while preserving quality and food safety.
For best texture, I usually aim for 130°F to 135°F for medium-rare.
8. Use Fresh Garlic and Herbs for Better Flavor
Secret Tip: Dried seasonings have their place, but fresh garlic, parsley, and herbs make cowboy butter taste brighter, fresher, and much more vibrant. That fresh herb finish really stands out against smoky grilled steak and gives the sauce that restaurant-quality flavor people love.
9. Don’t Overcook This Cut
Secret Tip: Flank steak is best when cooked to medium-rare or medium. Going too far can make it firmer and less tender because this is a lean cut that cooks quickly over high heat. I like to pull it off the grill a little early and let carryover heat finish the job naturally.
10. Let the Grill Get Properly Hot First
Secret Tip: One mistake I see often is putting steak on the grill before it’s fully heated. A properly hot grill helps create that flavorful crust quickly while keeping the inside juicy. Medium-high heat gives you the best balance of charred flavor and tender grilled steak texture.
11. Don’t Press the Steak While Grilling
Secret Tip: It may be tempting to press the steak down with tongs or a spatula, but that pushes flavorful juices out of the meat. Let the steak grill undisturbed and only flip when it naturally releases more easily.
12. Finish with Lemon for Extra Brightness
Secret Tip: If you want to make the buttery sauce feel even more balanced, squeeze a little fresh lemon over the finished steak right before serving. That pop of brightness cuts through the richness and makes the whole grilled steak dinner taste fresher and more layered.
A few simple steak-grilling techniques—like proper resting, slicing correctly, and finishing with fresh cowboy butter—can turn a quick flank steak dinner into a juicy steakhouse-style meal that tastes restaurant-worthy at home.
Common Mistakes to Avoid And How to Solve Them
Even though this is a simple grilled steak recipe, a few small mistakes can completely change the final result. The good news is that most of them are easy to fix once you know what to watch for. These are the most common flank steak mistakes I see—and the simple steak-grilling tips that help prevent them.
Mistake 1: The Steak Turns Tough
Why it happens: One of the biggest reasons flank steak feels tough is because it was sliced with the grain instead of against it. Flank steak has long muscle fibers, and cutting in the wrong direction leaves those fibers intact, which creates a chewy texture.
How to fix it: Always look at the direction of the grain before slicing, then cut thin slices across the fibers, not with them. This simple steak-cutting technique shortens the muscle fibers and makes every bite much more tender.
Mistake 2: The Steak Comes Out Dry
Why it happens: Flank steak is a lean cut, so it can go from juicy to dry very quickly if it stays on the grill too long.
How to fix it: Use an instant-read meat thermometer instead of guessing. For the best juicy steak texture, remove it at 130°F to 135°F for medium-rare or 140°F to 145°F for medium. Using a food thermometer helps cook meat accurately while preserving both quality and food safety.
Mistake 3: The Butter Sauce Separates
Why it happens: If the butter is too hot when the herbs, lemon, and Dijon are added, the sauce can separate instead of becoming smooth and balanced.
How to fix it: Let the melted butter cool slightly before whisking everything together. This helps the garlic herb butter sauce stay silky, flavorful, and evenly blended.
Mistake 4: The Steak Sticks to the Grill
Why it happens: Grill grates weren’t hot enough, weren’t cleaned properly, or weren’t lightly oiled before cooking.
How to fix it: Preheat the grill fully, clean the grates, and lightly oil them before placing the steak down. A properly heated grill helps create better searing and reduces sticking.
Mistake 5: The Steak Lacks Flavor
Why it happens: This usually happens when the steak was under-seasoned or all the cowboy butter was used during grilling instead of finishing the steak after slicing.
How to fix it: Season generously before cooking and always reserve some butter sauce for serving. That final spoonful of garlic herb butter over sliced steak adds bold flavor and creates that steakhouse-style finish.
Mistake 6: The Steak Looks Good but Feels Chewy
Why it happens: Even perfectly grilled steak can feel chewy if it’s sliced too soon.
How to fix it: Let the steak rest for 8 to 10 minutes after grilling so the juices redistribute throughout the meat before slicing.
Mistake 7: The Steak Doesn’t Get a Good Sear
Why it happens: The steak was placed on the grill before it was hot enough, or surface moisture prevented proper browning.
How to fix it: Pat the steak dry before seasoning and make sure the grill is fully preheated to medium-high heat. This helps create those flavorful charred edges and caramelized grill marks.
Mistake 8: The Steak Is Overcooked on the Outside but Undercooked Inside
Why it happens: This often happens when very cold steak goes straight from the refrigerator to the grill.
How to fix it: Let the steak sit at room temperature for about 20 to 30 minutes before cooking so it cooks more evenly from edge to center.
Mistake 9: The Butter Burns on the Grill
Why it happens: Too much butter was brushed on too early, causing flare-ups or burnt garlic.
How to fix it: Brush lightly during the final minute of cooking and save most of the cowboy butter for finishing after slicing.
Cowboy Butter Grilled Flank Steak turns out best when grilled hot and fast, sliced correctly, rested properly, and finished with fresh garlic herb butter instead of rushing the simple steak fundamentals that make all the difference.

Make It Healthier Options for Cowboy Butter Grilled Flank Steak
This steak dinner already delivers plenty of bold flavor and satisfying protein, but there are a few easy ways to lighten it while still keeping that rich garlic herb finish.
Use Less Butter But Keep the Flavor
You can reduce the butter slightly and still enjoy that signature cowboy butter sauce by increasing fresh lemon juice, garlic, parsley, and herbs. This helps create a lighter grilled steak topping with bright flavor while cutting back on richness.
Pair with More Vegetables
Serving this sliced steak with grilled vegetables, roasted broccoli, asparagus, or a crisp salad helps create a more balanced high-protein dinner while adding fiber, color, and volume. If you need inspiration for a lighter side dish, my Garlic Butter Steak Bites with Potatoes makes a delicious pairing that complements smoky grilled beef beautifully.
Choose a Leaner Portion
Flank steak is naturally leaner than many premium steak cuts, but portion control can make this easy steak dinner feel lighter while still delivering satisfying flavor and protein. Thinly sliced steak served alongside vegetables often creates a more balanced plate.
Use Olive Oil in Part of the Sauce
Replacing part of the butter with olive oil can lighten the richness while still giving you a flavorful finishing sauce. This simple swap keeps the garlic herb butter profile while creating a lighter option for those looking for a healthier grilled steak meal.
Serve Over Greens Instead of Potatoes
One of my favorite lighter serving ideas is slicing the grilled flank steak over a large salad with grilled vegetables, fresh greens, and lemon for a fresh, lower-carb dinner option that still feels hearty and satisfying.
According to The Nutrition Source, building meals around lean protein and vegetables can help support balanced eating patterns while adding more nutrient-dense foods to your plate.

Easy Variations You Can Try with Cowboy Butter Grilled Flank Steak
One of my favorite things about this recipe is how easy it is to customize depending on your mood, the season, or whatever ingredients you have in the kitchen. The juicy grilled steak and bold garlic herb butter create such a flavorful base that you can easily take it in different directions without losing what makes this meal special.

Stir extra red pepper flakes, cayenne, chipotle powder, or a dash of hot sauce into the cowboy butter for a spicy steak dinner with sweet heat and smoky depth. I especially love this version for summer cookouts because the little kick balances the richness of the butter so well.
Smoky BBQ Version
Why it works: If you want deeper backyard grill flavor, this variation leans into smoky BBQ-inspired seasoning.
Add smoked chipotle, barbecue seasoning, or a touch of smoked paprika to the butter sauce for a richer grilled steak flavor that tastes bold, smoky, and a little more rustic.
This version pairs especially well with grilled corn, potatoes, or summer barbecue sides.
Herb Lover’s Version
Why it’s fresh: If you love bright herb-forward flavors, this variation makes the butter feel lighter and fresher.

Low-Carb Bowl Version
Why it’s lighter: If you want a lighter steak dinner, turn this into a protein-packed bowl instead of a traditional plated meal.
Serve sliced steak over cauliflower rice, roasted vegetables, or grilled zucchini for a lower-carb dinner that still feels hearty and satisfying.
According to The National Institutes of Health, building meals around lean protein and vegetables can help create balanced, nutrient-rich eating patterns.
Steak Sandwich Version
Why people love it: Leftover sliced steak works beautifully piled into toasted bread with warm cowboy butter, caramelized onions, and fresh greens.
It turns into a steakhouse-style sandwich that feels rich, juicy, and incredibly satisfying for lunch or a quick second-day dinner.

Storage and Reheat Tips for Cowboy Butter Grilled Flank Steak
One of the things I really love about this recipe is that the leftovers never feel like an afterthought. In fact, the rich garlic herb butter settles into the steak even more as it rests, giving those slices incredible flavor the next day. I’ve tucked leftovers into wraps, piled them onto salads, turned them into steak rice bowls, and even made quick steak sandwiches when I wanted a satisfying meal without starting from scratch again. When stored and reheated properly, this juicy grilled steak can taste nearly as good the next day as it did fresh off the grill.
How to Refrigerate Leftovers the Right Way
Why it matters: Proper storage helps preserve moisture, flavor, and tenderness so your leftover steak doesn’t dry out or lose its steakhouse-style quality.
Once the steak has cooled, place sliced leftovers in an airtight container and refrigerate for up to 3 to 4 days. If you have extra cowboy butter sauce, I recommend storing it separately instead of pouring it all over the meat before refrigerating. This helps prevent the steak from becoming overly saturated overnight while giving you fresh buttery flavor when reheating.
For even better texture, place slices in a shallow container rather than stacking them tightly, which helps the meat cool evenly and maintain its quality.
The Best Ways to Reheat Without Drying It Out
Why this works: Flank steak is a lean cut, so reheating it too aggressively can make it tougher and drier than it should be.
My favorite trick is reheating gently and adding a small spoonful of butter, broth, or leftover cowboy butter to help bring moisture back into the meat.
Skillet reheating: Warm steak slices over low to medium-low heat for just a few minutes with a splash of broth or butter. This is usually my favorite method because it helps preserve texture while reviving that juicy grilled steak flavor.
Oven reheating: Place steak in a baking dish, cover loosely with foil, and warm at 300°F to 325°F for about 8 to 10 minutes. This is a great option if you’re reheating a larger portion.
Microwave reheating: Use lower power and heat in short intervals to avoid overcooking. Covering the steak lightly can also help hold in moisture.
According to FoodSafety.gov, leftovers should be reheated safely to an internal temperature of 165°F for food safety.
Can You Freeze It?
Good news: Yes, this easy grilled steak recipe freezes surprisingly well when stored correctly.
Cooked steak can be frozen in a freezer-safe container or tightly wrapped freezer bag for up to 2 months.
For best results, slice the steak before freezing so it’s easier to portion later. Remove as much air as possible to help prevent freezer burn, and if you can, freeze the garlic herb butter separately so the flavors stay fresh and vibrant.
When you’re ready to use it, thaw overnight in the refrigerator and reheat gently instead of using high heat, which can make the meat chewy.
Sam’s Favorite Meal Prep Ideas for Leftovers
Why I love this: Leftover steak becomes one of the easiest high-protein meal prep ingredients to work with during busy weeks.
I’ve used leftover slices in warm rice bowls with roasted vegetables, tucked them into wraps for quick lunches, layered them onto protein-packed salads, stuffed them into toasted sandwiches, and even served them over baked potatoes for a hearty comfort-food dinner.
This is one of those recipes that keeps giving long after dinner is over, which makes it perfect for make-ahead meals, quick lunch prep, and easy weeknight leftovers that still feel exciting.
A Few Extra Tips for Best Texture
Small details make a big difference: Try to avoid reheating steak multiple times. Reheat only the portion you plan to eat so the remaining slices stay tender and flavorful.
If the steak seems a little dry after storage, a drizzle of warm cowboy butter or a splash of broth can instantly bring life back to it.
With a little care, leftover steak can turn into easy high-protein lunches, quick dinner bowls, and satisfying next-day meals that feel just as crave-worthy as the original dinner.

Frequently Asked Questions About Cowboy Butter Grilled Flank Steak
What is the best doneness for flank steak on the grill?
Flank steak is usually best cooked to medium-rare to medium, which keeps it juicy and tender while preserving its rich beefy flavor. Because this cut is lean, cooking it too far can make it tougher and drier. A good target is around 130°F to 145°F, depending on your preference.
How do you keep flank steak tender after grilling?
The two biggest secrets are not overcooking it and slicing against the grain. Flank steak has long muscle fibers, so cutting across them shortens those fibers and makes every bite much more tender. Letting the steak rest before slicing also helps keep the juices inside instead of running out onto the cutting board.
Can I make cowboy butter ahead of time?
Yes, the garlic herb butter sauce can be made ahead and stored in the refrigerator for up to 3 days. Simply warm it gently before serving so it becomes pourable again. This makes meal prep easier and gives you a quick steak sauce ready whenever you grill.
Can I cook flank steak without an outdoor grill?
Absolutely. If you don’t have a grill, you can cook it in a cast iron skillet, grill pan, or under the broiler. High heat is important because it helps create that flavorful seared crust while keeping the inside juicy.
How long should I grill flank steak?
For most flank steaks, 4 to 6 minutes per side over medium-high heat works well, depending on thickness and desired doneness. Using a meat thermometer is the easiest way to avoid guesswork. According to the Cleveland Clinic, a food thermometer helps cook meat more accurately while reducing the risk of overcooking.
Why is my grilled flank steak chewy?
Chewy steak usually happens for one of three reasons: it was overcooked, not rested, or sliced with the grain instead of against it. This cut cooks quickly, so even a couple of extra minutes can change the final texture.
Can I marinate flank steak before making this recipe?
Yes, although this recipe already delivers bold flavor through seasoning and garlic herb butter, you can marinate the steak for extra tenderness and deeper flavor if you’d like. A simple marinade with oil, acid, and seasonings works especially well for flank steak.
Is flank steak a good cut for meal prep?
Yes, flank steak is a great high-protein meal prep option because leftover slices work well in wraps, salads, rice bowls, sandwiches, and quick lunch boxes. Stored properly, it reheats beautifully for easy make-ahead meals.
Can I freeze cooked flank steak?
Yes, cooked steak freezes well for up to 2 months when stored in a freezer-safe container or airtight freezer bag. For best texture, thaw it overnight in the refrigerator and reheat gently instead of using high heat.
Is flank steak a lean cut of beef?
Yes, flank steak is generally considered a leaner cut compared to fattier steak options, while still offering plenty of protein and rich flavor. Beef provides important nutrients like protein, iron, zinc, and B vitamins as part of a balanced diet
What should I serve with cowboy butter steak?
This steak pairs beautifully with grilled vegetables, roasted potatoes, corn on the cob, fresh salads, rice bowls, garlic bread, mashed potatoes, or low-carb cauliflower rice, depending on the kind of meal you want to build around it.
Can I use another cut of steak for this recipe?
Yes, if flank steak isn’t available, you can use skirt steak, flat iron steak, sirloin, or ribeye, adjusting cooking time based on thickness. The cowboy butter sauce works beautifully with many grilled steak cuts, making this recipe easy to adapt.
Can I use a gas grill or charcoal grill for this recipe?
Yes, both work beautifully. A gas grill gives steady temperature control, while a charcoal grill adds deeper smoky flavor that pairs especially well with garlic herb butter. The key is preheating properly and cooking over medium-high heat so the steak gets a flavorful crust without drying out.
Do I need to marinate flank steak before grilling?
Not necessarily. Flank steak often benefits from marinades, but in this recipe, the seasoning blend and rich cowboy butter sauce already provide plenty of bold flavor. If you do want to marinate it, keep it simple and avoid very sugary marinades that can burn quickly on the grill.
Should I poke holes in flank steak before cooking?
No, I don’t recommend it. Piercing the meat can allow flavorful juices to escape during cooking. Instead, season the surface well and let the grill do the work.
Why should I let steak rest after grilling?
Resting allows the juices to redistribute throughout the meat instead of spilling out immediately when sliced. This simple step helps keep steak tender and juicy. According to WebMD, proper cooking and resting techniques can improve both food quality and safe meat preparation.
How do I know when flank steak is done without cutting into it?
The best method is using an instant-read meat thermometer. Cutting into steak while it cooks releases juices and makes it harder to judge doneness accurately. Thermometers give a much more reliable result, especially with lean cuts that cook quickly.
Can I make this recipe in a cast iron skillet?
Yes, and it works surprisingly well. A cast iron skillet steak recipe gives you excellent sear and crust when an outdoor grill isn’t available. Make sure the skillet is very hot before adding the steak for the best steakhouse-style finish.
What if I don’t have Dijon mustard for the butter sauce?
You can substitute a small amount of yellow mustard, whole grain mustard, or even leave it out in a pinch. Dijon gives a smoother tangy flavor, but the sauce will still be delicious with slight adjustments.
Can I use dried herbs instead of fresh herbs?
Yes, although fresh herbs give the butter a brighter, more vibrant flavor. If using dried herbs, use less because dried herbs are more concentrated.
Why is flank steak considered a good grilling cut?
Flank steak is a popular grilling cut because it cooks quickly, has rich beefy flavor, and slices beautifully when prepared correctly. It’s also often more budget-friendly than premium steak cuts, making it a great option for easy summer grilling dinners.
What temperature should the grill be for flank steak?
A grill temperature of about 450°F or medium-high heat is ideal. This creates a flavorful char on the outside while keeping the inside juicy.
Can I use this butter sauce on other meats?
Absolutely. Cowboy butter is delicious on grilled chicken, shrimp, pork chops, salmon, and even roasted vegetables. It’s one of those versatile garlic butter sauces that instantly upgrades simple meals.
Is this a good recipe for summer cookouts?
Yes, this is one of those easy backyard BBQ steak recipes that feels perfect for summer entertaining because it cooks fast, slices beautifully, and serves well for both family dinners and guests.
Can I make this recipe dairy-free?
Yes, you can use a plant-based butter alternative instead of regular butter. Choose one with a rich flavor and good melting quality for the best result.
What sides pair best with grilled flank steak?
Some of my favorite sides include grilled corn, roasted potatoes, fresh salads, garlic bread, mashed potatoes, rice bowls, sautéed vegetables, and cauliflower rice for a lower-carb option.
Can leftover steak be eaten cold?
Yes, leftover slices are delicious cold in steak salads, wraps, sandwiches, and protein bowls. This makes it a great meal prep steak recipe for busy weeks.
Is flank steak healthy?
Flank steak can be a great source of protein, iron, zinc, and B vitamins, especially when paired with balanced side dishes. According to Mayo Clinic, lean beef can provide important nutrients as part of a varied diet.
Why does garlic butter make steak taste better?
Butter helps carry flavor across the meat while garlic, herbs, lemon, and seasonings create contrast against the richness of beef. That balance of richness, brightness, and savory depth is what makes cowboy butter so crave-worthy.
Can I make this recipe for meal prep lunches?
Yes, this is one of my favorite high-protein meal prep steak recipes because leftover slices can be turned into wraps, salads, rice bowls, sandwiches, and quick lunch plates throughout the week.
