Ingredients

Here’s everything you’ll need to make this dish a success:

2 pounds russet potatoes, peeled and chopped
4 tablespoons unsalted butter, softened
½ cup heavy cream (or whole milk)
3 large egg yolks
½ teaspoon salt (or more to taste)
¼ teaspoon black pepper
¼ teaspoon ground nutmeg (optional, but classic)
½ cup grated Parmesan cheese (optional)
1 egg yolk + 1 tablespoon water (for egg wash)

Ingredient Highlights

Russet Potatoes: High starch content makes them ideal for a smooth, fluffy interior.
Butter & Cream: These bring richness and a silky texture.
Egg Yolks: Add structure and beautiful color, helping the piped swirls hold their shape.
Parmesan Cheese: Optional, but adds umami and boosts the crispy texture on the edges.
Nutmeg: A small pinch enhances depth without overpowering the dish.

Step-by-Step Instructions

Step 1: Cook the Potatoes

Place the chopped potatoes in a large pot, cover with cold salted water, and bring to a boil. Simmer until fork-tender—about 15–20 minutes.

Step 2: Drain and Dry

Drain the potatoes thoroughly and return them to the hot pot for 1–2 minutes to let excess moisture evaporate.

Step 3: Mash

Use a potato ricer or masher to mash the potatoes until smooth. Avoid using a food processor to prevent gluey texture.

Step 4: Mix the Base

Stir in the butter and warm cream until fully combined. Add salt, pepper, and nutmeg (if using).

Step 5: Add Egg Yolks

Let the potatoes cool slightly, then mix in the egg yolks and Parmesan cheese. Stir until smooth.

Step 6: Pipe the Potatoes

Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper. Transfer the potato mixture to a piping bag fitted with a large star tip and pipe 3-inch swirls, spacing 1 inch apart.

Step 7: Apply Egg Wash

Mix 1 egg yolk with 1 tablespoon water. Lightly brush the tops of each swirl to help them brown beautifully in the oven.

Step 8: Bake

Bake for 25–30 minutes or until golden and slightly crisp around the edges.

Step 9: Serve

Let cool slightly and serve warm as a side dish.

Pro Tips for Perfect Duchess Potatoes

Choose Starchy Potatoes: Russets or Yukon Golds deliver the fluffiest results.
Dry Thoroughly: Moisture is the enemy of crispness. Always dry the potatoes well before mashing.
Use a Ricer: A potato ricer or food mill makes the smoothest texture, perfect for piping.
Warm Cream & Butter: Helps incorporate smoothly into the potatoes without clumping.
Pipe When Warm: The mixture pipes best when it’s warm but not hot.
Use a Star Tip: A large open star piping tip creates those iconic ridges that brown beautifully.
Don’t Skip the Egg Wash: It’s what gives Duchess Potatoes that irresistible golden crust.
Chill If Needed: If the mixture is too soft, refrigerate for 20–30 minutes before piping.

Frequently Asked Questions

Can I make Duchess Potatoes in advance?
Yes! Pipe and chill the unbaked potatoes, then bake just before serving.

What if I don’t have a piping bag?

Why are my Duchess Potatoes spreading out?
The mixture may be too wet or warm. Try chilling it before piping and reduce the cream slightly next time.

Can I reheat them?
Yes, reheat in the oven at 350°F until warmed through. Avoid microwaving—they lose their texture.
