Instructions

  1. Step 1: Preheat the oven to 300°F. In a small bowl, combine 2 tbsp za’atar, 1 medium finely chopped preserved lemon, 6 minced garlic cloves, 3 tbsp olive oil, 2 tbsp chopped fresh rosemary, 1 tbsp chopped fresh thyme, 2 tsp salt, and 1 tsp black pepper to form a thick paste.
  2. Step 2: Rub this za’atar and preserved lemon mixture evenly over the entire 3-pound bone-in leg of lamb. 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: Roast the lamb in the preheated oven for 3 hours, basting with pan juices every 45 minutes, until the meat is fork-tender and a thermometer inserted into the thickest part reads 145°F for medium-rare.
  4. Step 4: Remove the lamb from the oven, tent with foil, and let rest for 15 minutes before carving. Pour the pan juices into a small saucepan and simmer over medium heat for 5 minutes until slightly thickened to serve as a jus.
