Instructions

  1. Step 1: Preheat your oven to 300°F (150°C). Pat dry 3 lbs bone-in lamb shoulder and score the fat lightly with a knife.
  2. Step 2: Peel and thinly slice 6 garlic cloves and finely chop 4 sprigs of fresh rosemary. Combine with 3 tbsp olive oil, 2 tsp sea salt, 1 tsp freshly ground black pepper, and 2 tbsp lemon juice.
  3. Step 3: Rub the garlic-rosemary mixture all over the lamb shoulder, making sure to work some under the scored fat.
  4. Step 4: Place the lamb in a roasting pan, pour 1/2 cup water into the bottom to keep it moist, and cover tightly with foil.
  5. Step 5: Roast in the preheated oven for about 3 hours, basting every hour with pan juices, until the meat is fall-apart tender.
  6. Step 6: Remove foil and increase oven temperature to 425°F (220°C). Roast uncovered for 15 minutes to crisp the exterior.
  7. Step 7: Let rest for 15 minutes before slicing and serving, spooning the pan juices over the lamb.
