Instructions

  1. Step 1: Preheat your oven to 300°F. Pat dry 3 lbs bone-in lamb shoulder and rub it with 3 tbsp extra virgin olive oil, 1 tsp sea salt, and 1/2 tsp freshly ground black pepper.
  2. Step 2: Peel and crush 6 garlic cloves and finely chop 4 sprigs of fresh rosemary; rub this mixture evenly over the lamb, then drizzle 2 tbsp lemon juice on top.
  3. Step 3: Place the lamb in a roasting pan, add 1/2 cup water to the bottom to keep it moist, cover tightly with foil, and roast in the oven for 3 hours until the meat is tender and falling off the bone.
  4. Step 4: Remove the foil and roast uncovered for an additional 15 minutes to brown the exterior, then rest the lamb for 15 minutes before slicing and serving.
