Ingredients

Instructions

  1. Step 1: Preheat oven to 300°F. Rub 3 lbs bone-in lamb shoulder with 3 tbsp olive oil, 2 tbsp sumac, 1 tbsp ground cumin, 2 tbsp chopped fresh rosemary, 4 minced garlic cloves, 1 1/2 tsp salt, and 1 tsp black pepper, ensuring even coating.
  2. Step 2: Place the lamb in a roasting pan and scatter 1 chopped preserved lemon around it. Pour 1 cup water into the pan to keep the meat moist during roasting.
  3. Step 3: Cover the pan tightly with foil and roast in the preheated oven for 3 hours, until the lamb is fork-tender and aromatic.
  4. Step 4: Remove foil and increase oven temperature to 425°F; roast uncovered for an additional 15 minutes to crisp the edges.
  5. Step 5: Let the lamb rest for 15 minutes before slicing and serving with pan juices.
