Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. In a small bowl, combine 3 tbsp chopped fresh rosemary, 6 minced garlic cloves, 2 tsp kosher salt, 1 tsp black pepper, 3 tbsp olive oil, and 1 tbsp lemon zest to form a herb paste.
  2. Step 2: Pat dry 4 lbs bone-in lamb shoulder. Rub the herb paste all over the lamb, pressing it into the surface.
  3. Step 3: Place the lamb shoulder on a rack in a roasting pan. Roast uncovered for 3 to 3.5 hours, or until internal temperature reaches 190°F and meat is tender.
  4. Step 4: Remove from oven and let rest for 20 minutes before carving against the grain. Serve with pan juices spooned over the slices.
