Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Rub 3 lbs bone-in lamb shoulder all over with 3 tbsp olive oil, 1 1/2 tsp salt, 1 tsp black pepper, 1 tbsp lemon zest, and 2 tbsp fresh oregano leaves.
  2. Step 2: Place lamb in a large heavy ovenproof pot. Add 8 smashed garlic cloves, 3 sprigs fresh rosemary, 1 large quartered onion, and 2 bay leaves around the lamb.
  3. Step 3: Pour 1 cup white wine over the lamb and cover the pot tightly with a lid or foil.
  4. Step 4: Slow cook in the oven for 3.5 to 4 hours until the lamb is fork-tender and the meat easily pulls away from the bone.
  5. Step 5: Remove the lid for the last 30 minutes to allow the surface to brown and the sauce to reduce slightly.
  6. Step 6: Let the lamb rest for 10 minutes before shredding or slicing. Serve with pan juices spooned over.
