Instructions

  1. Step 1: Preheat oven to 325°F (160°C). Pat dry 4 lbs bone-in lamb shoulder and season all over with 2 tsp salt and 1 tsp black pepper.
  2. Step 2: Using a small knife, make 12 small incisions all over the lamb and insert slices of 6 garlic cloves evenly; rub 2 tbsp chopped fresh oregano and 1 tbsp lemon zest mixed with 3 tbsp extra virgin olive oil all over the meat.
  3. Step 3: Place the lamb in a roasting pan and add 1 cup water to the bottom to keep the meat moist during cooking.
  4. Step 4: Cover the pan tightly with foil and roast for 3 hours until the lamb is very tender and pulls apart easily.
  5. Step 5: Remove foil and increase oven temperature to 425°F (220°C); roast uncovered for 15 minutes to brown and crisp the exterior.
  6. Step 6: Let the lamb rest for 15 minutes before slicing or shredding to serve with pan juices.
