Instructions

  1. Step 1: Preheat oven to 300°F. Using a sharp knife, make 12 small incisions all over the 4 lb bone-in lamb shoulder and insert 6 sliced garlic cloves evenly.
  2. Step 2: In a small bowl, mix 1/4 cup olive oil, 3 tbsp chopped fresh rosemary, 2 tbsp chopped fresh sage, 2 tbsp kosher salt, and 1 tbsp freshly ground black pepper. Rub this herb mixture all over the lamb, ensuring full coverage.
  3. Step 3: Place the lamb in a large roasting pan surrounded by 1 large quartered yellow onion, 3 medium carrots cut into 2-inch chunks, and 2 celery stalks cut into 2-inch chunks.
  4. Step 4: Pour 1/2 cup dry white wine into the pan and cover tightly with foil. Roast in the oven for 4 hours, basting every hour with pan juices, until the lamb is fork-tender and falling off the bone.
  5. Step 5: Remove foil and roast uncovered for an additional 20 minutes to brown the exterior. Let the lamb rest for 15 minutes before slicing and serving with roasted vegetables.
