Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Rub 3 lbs bone-in lamb shoulder all over with 6 minced garlic cloves, 2 tbsp chopped fresh rosemary, 3 tbsp olive oil, 2 tsp sea salt, and 1 tsp black pepper, massaging the seasoning into the meat.
  2. Step 2: Place the lamb in a roasting pan and roast uncovered for 3 hours, basting every hour with its juices, until lamb is fork-tender and internal temperature reaches 195°F.
  3. Step 3: While lamb roasts, combine 1/2 cup chopped fresh parsley, 1/4 cup chopped fresh mint leaves, 2 tbsp lemon juice, 1 tbsp red wine vinegar, and 2 tbsp olive oil in a small bowl to make the herb sauce; season with a pinch of salt.
  4. Step 4: Remove lamb from oven and let rest for 15 minutes before slicing. Serve with the fresh herb sauce drizzled on top.
