Instructions

  1. Step 1: Preheat your oven to 325°F (160°C). Pat dry 3 lbs of lamb shoulder with paper towels. Finely mince 6 garlic cloves and 4 sprigs of fresh rosemary leaves.
  2. Step 2: In a small bowl, combine 3 tbsp olive oil, minced garlic, rosemary, 2 tsp sea salt, and 1 tsp black pepper. Rub this mixture all over the lamb, ensuring full coverage.
  3. Step 3: Place the lamb in a roasting pan, drizzle 2 tbsp lemon juice over it, and cover loosely with foil. Roast in the oven for 3 hours, basting every hour with the pan juices, until the meat is tender and easily pulls apart.
  4. Step 4: Remove the foil and roast uncovered for an additional 15 minutes to brown the exterior. Let the lamb rest for 15 minutes before carving.
