Ingredients

Instructions

  1. Step 1: In a bowl, combine 6 minced garlic cloves, 2 tbsp chopped rosemary, 1 tbsp chopped thyme, 1/4 cup olive oil, 2 tbsp lemon juice, 2 tsp sea salt, and 1 tsp freshly ground black pepper to form a herb garlic marinade.
  2. Step 2: Rub the 3 lbs lamb shoulder thoroughly with the marinade, ensuring all sides are coated; cover and refrigerate for at least 4 hours or overnight for best flavor infusion.
  3. Step 3: Preheat oven to 300°F. Place the marinated lamb in a roasting pan and add 1/2 cup water to the bottom to keep the meat moist.
  4. Step 4: Roast the lamb for 3 to 3 1/2 hours, basting every hour with pan juices, until the internal temperature reaches 195°F and the meat is fork-tender.
  5. Step 5: Remove the lamb from the oven and let it rest for 15 minutes before slicing to lock in juices and enhance tenderness.
