Instructions

  1. Step 1: Preheat oven to 275°F. In a small bowl, mix 5 minced garlic cloves, 2 tbsp chopped fresh rosemary, 4 tbsp olive oil, 2 tsp sea salt, and 1 tsp black pepper.
  2. Step 2: Rub the mixture evenly all over a 3 lb bone-in lamb shoulder. Place lamb in a roasting pan.
  3. Step 3: Roast lamb for 4 hours uncovered, basting every hour with pan juices, until meat is tender and falls off the bone.
  4. Step 4: While lamb roasts, combine 1/2 cup chopped green olives, 2 tbsp rinsed capers, 1 tsp lemon zest, and 2 tbsp chopped fresh parsley in a bowl; set aside.
  5. Step 5: Remove lamb from oven and let rest 15 minutes. Serve slices of lamb topped with the olive and caper relish for a bright, savory contrast.
