Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F (160°C). Rub 4 lbs bone-in lamb shoulder all over with 2 tsp salt, 1 tsp black pepper, and 3 tbsp olive oil.
  2. Step 2: Place the lamb in a roasting pan. Mix 2 tbsp chopped fresh rosemary with 4 minced garlic cloves and press evenly over the lamb surface.
  3. Step 3: Roast uncovered for 2 hours, basting every 30 minutes with pan juices.
  4. Step 4: Meanwhile, in a small saucepan, combine 1/2 cup apricot preserves, 2 tbsp apple cider vinegar, and 1/2 cup water. Heat gently over low heat for 5 minutes until the glaze is smooth and slightly thickened.
  5. Step 5: After 2 hours, brush the apricot glaze generously over the lamb and increase oven temperature to 400°F (200°C). Roast for an additional 20 minutes until the glaze caramelizes and the lamb is tender.
  6. Step 6: Remove from oven and rest the roast covered loosely with foil for 15 minutes before slicing and serving.
