Instructions

  1. Step 1: In a bowl, whisk together 6 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 tbsp fresh thyme leaves, 1 tbsp lemon zest, 2 tbsp lemon juice, 1/4 cup extra virgin olive oil, 2 tsp kosher salt, and 1 tsp freshly ground black pepper to create a herb marinade.
  2. Step 2: Rub the marinade all over the 4 lbs bone-in lamb shoulder, ensuring full coverage. Cover and refrigerate for at least 4 hours or overnight to let flavors penetrate.
  3. Step 3: Preheat oven to 325°F (160°C). Place the lamb shoulder fat side up in a roasting pan and pour 1/2 cup water or broth into the pan. Cover loosely with foil and roast for 3 hours.
  4. Step 4: Remove foil and roast uncovered for an additional 30 minutes to brown and crisp the exterior. The lamb is done when it reaches an internal temperature of 195°F and is tender enough to pull apart easily. Let rest 15 minutes before slicing.
