Instructions

  1. Step 1: Preheat the oven to 300°F. In a small bowl, mix 1/4 cup olive oil, 6 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 tbsp dried oregano, 1 tbsp lemon zest, 2 tsp salt, and 1 tsp black pepper to create a herb paste.
  2. Step 2: Rub the herb paste all over a 4 lb bone-in lamb shoulder, massaging it into the meat thoroughly. Place the lamb in a roasting pan and pour 1 cup water into the pan to keep the meat moist during cooking.
  3. Step 3: Cover the roasting pan tightly with foil and roast the lamb for 4 to 4.5 hours until the meat is fork-tender and pulls apart easily. Halfway through cooking, baste the lamb with pan juices for extra flavor.
  4. Step 4: Remove the foil and increase the oven temperature to 425°F. Roast uncovered for an additional 15 minutes to brown and crisp the exterior. Let the lamb rest for 15 minutes before slicing and serving with pan juices.
