Instructions

  1. Step 1: Preheat oven to 300°F. In a small bowl, combine 4 tbsp olive oil, 3 tbsp chopped fresh rosemary, 2 tsp lemon zest, 6 minced garlic cloves, 2 tsp salt, and 1 tsp black pepper to form a paste.
  2. Step 2: Rub the paste all over the 4 lbs bone-in lamb shoulder, massaging it into the meat thoroughly. Place lamb in a roasting pan with 3 large chopped carrots and 2 quartered onions arranged around it.
  3. Step 3: Pour 1 cup water into the pan, cover tightly with foil, and roast in the oven for 4 hours or until the lamb is fork-tender and falling apart.
  4. Step 4: Remove foil and roast uncovered for an additional 20 minutes to brown the exterior. Let rest for 15 minutes before slicing and serving with the roasted vegetables.
