Ingredients

Instructions

  1. Step 1: Preheat oven to 300°F. In a small bowl, combine 3 tbsp za’atar seasoning, 1/4 cup lemon juice, 1/4 cup olive oil, 5 minced garlic cloves, 2 tbsp chopped fresh rosemary, 2 tsp salt, and 1 tsp black pepper to form a marinade.
  2. Step 2: Rub the marinade all over the 3 lbs lamb shoulder, coating evenly. 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 pan tightly with foil and roast in the oven for 3.5 to 4 hours until the lamb is fork-tender and falling apart. Remove foil during the last 30 minutes to brown the surface.
  4. Step 4: Let the lamb rest for 15 minutes before slicing. Serve with pan juices spooned over the top.
