Ingredients

Instructions

  1. Step 1: In a small bowl, combine 1/4 cup olive oil, 2 tbsp chopped fresh rosemary, 2 tbsp chopped fresh oregano, 4 minced garlic cloves, 3 tbsp lemon juice, 2 tsp sea salt, and 1 tsp black pepper to create the marinade.
  2. Step 2: Rub the marinade thoroughly over the entire surface of the 3 lbs lamb shoulder, then cover and refrigerate for at least 4 hours or overnight for best flavor.
  3. Step 3: Preheat oven to 300°F (150°C). Place the marinated lamb shoulder in a roasting pan and pour 1/2 cup water into the bottom of the pan to maintain moisture.
  4. Step 4: Roast the lamb shoulder for 3 to 3.5 hours, basting every hour with pan juices, until the meat is tender and easily pulls apart with a fork.
  5. Step 5: Remove the lamb from the oven and let rest for 15 minutes before slicing or shredding. Serve with pan juices drizzled over the top.
