Ingredients
- 2 racks (about 2 lbs each) Colorado lamb racks
- 2 tbsp olive oil
- 2 tbsp, finely chopped fresh rosemary
- 4 cloves, minced garlic cloves
- 4 tbsp, softened unsalted butter
- 1 tsp salt
- 1 tsp, freshly ground black pepper
Instructions
- Step 1: Preheat grill to medium-high heat (about 400°F). Brush 2 Colorado lamb racks with 2 tbsp olive oil, then season evenly with 1 tsp salt and 1 tsp freshly ground black pepper.
- Step 2: Grill the lamb racks over direct heat for 4-5 minutes per side to develop a nice crust, then move to indirect heat and cook for another 10-12 minutes until the internal temperature reaches 135°F for medium-rare.
- Step 3: While lamb cooks, combine 4 tbsp softened unsalted butter with 2 tbsp finely chopped fresh rosemary and 4 minced garlic cloves in a small bowl.
- Step 4: Remove lamb racks from grill and let rest for 10 minutes. Spread the rosemary garlic butter evenly over the lamb racks while still warm, allowing it to melt and infuse flavor.
- Step 5: Slice between the ribs and serve immediately, enjoying the juicy lamb with the aromatic butter.
