Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F (160°C). In a bowl, combine 2 tbsp chopped fresh rosemary, 1 tbsp chopped fresh thyme, 6 minced garlic cloves, 1 tbsp lemon zest, 1 tbsp orange zest, 1/4 cup olive oil, 2 tsp salt, and 1 tsp black pepper to form a marinade.
  2. Step 2: Rub the marinade all over the 4 lbs bone-in lamb shoulder, massaging it into the meat thoroughly. Let it marinate at room temperature for 30 minutes.
  3. Step 3: Place the lamb shoulder in a roasting pan and add 1/2 cup water to the pan to keep the meat moist. Cover loosely with foil and roast for 3 hours, basting every hour with pan juices.
  4. Step 4: Remove the foil in the last 30 minutes of roasting to brown the outside until the surface is deeply caramelized and fragrant. Let rest for 15 minutes before slicing.
