How to Make Grilled Butterflied Leg of Lamb with Herb Rub

1. Combine Ingredients: In a mixing bowl, combine 2 tablespoons of olive oil, 2 tablespoons of chopped fresh rosemary, 2 tablespoons of chopped fresh thyme, 4 minced garlic cloves, 1 teaspoon of salt, 1 teaspoon of black pepper, and 1 teaspoon of lemon zest to create a fragrant herb rub.
2. Marinate the Lamb: Generously rub the herb mixture all over your butterflied leg of lamb (about 4 pounds), ensuring every inch is coated. Cover it and marinate in the refrigerator for at least 1 hour—overnight is even better for deeper flavor!
3. Preheat the Grill: Preheat your grill to medium-high heat, allowing it to reach a steady temperature which will give your lamb that perfect sear.
4. Prepare for Grilling: Remove the marinated lamb from the refrigerator and let it sit at room temperature for about 30 minutes. This helps ensure even cooking.
5. Grill the Lamb (First Side): Place the lamb on the grill, cut side down. Grill it for about 15 minutes or until it has beautiful grill marks and starts to brown nicely.
6. Flip and Finish Grilling: Carefully flip the lamb over and continue grilling for another 10-15 minutes. Aim for an internal temperature of 135°F for that perfect medium-rare doneness.
7. Rest Before Slicing: Once grilled to perfection, remove the lamb from the grill and let it rest for about 10 minutes before slicing. This allows juices to redistribute, making each bite tender and juicy.
Optional: For an added touch, serve with a sprinkle of fresh herbs on top!
