Ingredients

Instructions

  1. Step 1: Preheat oven to 300°F (150°C). In a small bowl, mix 4 tbsp olive oil, 3 tbsp chopped fresh rosemary, 1 tbsp ground native pepperberry, 4 minced garlic cloves, 2 tsp sea salt, and 1 tsp black pepper.
  2. Step 2: Rub this mixture all over the 4 lbs bone-in lamb shoulder, making sure to coat thoroughly.
  3. Step 3: Place the lamb in a roasting pan surrounded by 2 cups chopped carrots and 1 large quartered onion. Pour 1 cup water into the pan to keep the environment moist.
  4. Step 4: Cover the pan tightly with foil and roast in the oven for 4 hours until the lamb is fork-tender and falling off the bone.
  5. Step 5: Remove foil and increase oven temperature to 425°F (220°C). Roast uncovered for an additional 15 minutes to brown the exterior and crisp the edges.
  6. Step 6: Let the lamb rest for 15 minutes before carving and serving with the roasted vegetables.
