Idaho Cowboy Butter-Grilled Sirloin on Arteflame
Introduction
A mouthwatering thick-cut sirloin steak basted with rich, flavorful cowboy butter and grilled to perfection on the Arteflame grill. By using the center grill grate at 1,000°F, we lock in the juices with a perfect sear before finishing the steak on the flat cooktop. The result? A steakhouse-quality sirloin bursting with bold, buttery flavor.
Ingredients
- 2 thick-cut sirloin steaks (about 1.5 inches thick)
- 1/2 cup unsalted butter, melted
- 3 cloves garlic, minced
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh lemon juice
- 1 teaspoon smoked paprika
- 1 teaspoon red pepper flakes
- 1 tablespoon fresh parsley, chopped
- 1 teaspoon salt
- 1 teaspoon black pepper
- 1 teaspoon Worcestershire sauce
- Vegetable oil (for lighting the grill)
Instructions
Step 1: Fire Up the Arteflame Grill
- Pour a small amount of vegetable oil onto three paper napkins.
- Place the soaked napkins inside the grill and stack firewood over them.
- Light the paper and allow the fire to build for about 20 minutes until the grill is hot.
Step 2: Prepare the Cowboy Butter
- In a small bowl, mix the melted butter, minced garlic, Dijon mustard, lemon juice, smoked paprika, red pepper flakes, parsley, salt, black pepper, and Worcestershire sauce.
- Set aside for basting.
Step 3: Sear the Sirloin Steaks
- Pat the steaks dry and season with salt and black pepper.
- Place the steaks on the center grill grate at 1,000°F and sear for 2 minutes per side.
- Once the exterior has a deep, golden crust, move the steaks to the flat cooktop to finish cooking.
Step 4: Baste and Finish Cooking
- Use a brush to baste the steaks generously with cowboy butter as they cook on the flat cooktop.
- Cook until the internal temperature is 15°F below your target doneness (125°F for medium-rare, 135°F for medium, etc.).
- Remove steaks and let them rest for 5-10 minutes before slicing.
Tips
- Always remove your steak from the grill 15°F before your desired doneness—it will continue cooking as it rests.
- Use the different heat zones of the flat cooktop to control cooking speed and temperature.
- Basting with cowboy butter throughout the cooking process infuses the meat with incredible flavor.
Variations
-
Spicy Cowboy Butter: Add extra red pepper flakes and a dash of hot sauce for a fiery kick.
