Instructions
- Season the Steak: Place the steak cubes in a large bowl. Drizzle with olive oil, then add the salt, black pepper, garlic powder, and smoked paprika. Toss until evenly coated and let rest for 20 to 30 minutes.
- Prepare the Vegetables: Cut the bell peppers and red onion into similar-sized pieces so they cook evenly alongside the steak.
- Assemble the Kabobs: Thread the steak, peppers, and onions onto skewers, alternating the ingredients. Leave a small space between each piece to encourage even cooking and better browning.
- Make the Garlic Herb Butter: In a small bowl, combine the melted butter, garlic, parsley, thyme, rosemary, salt, and pepper. Reserve some for serving and set the rest aside for brushing during grilling.
- Preheat the Grill: Heat the grill to medium-high, about 400°F to 450°F (204°C to 232°C). Clean and lightly oil the grates to prevent sticking.
- Grill the Kabobs: Place the kabobs on the grill and cook for 8 to 10 minutes, turning every 2 to 3 minutes. During the last few minutes, brush generously with the garlic herb butter.
- Rest and Serve: Transfer the kabobs to a serving platter and let rest for 5 minutes. Brush with the reserved garlic herb butter, garnish with fresh parsley, and serve warm.
