Ingredients

Instructions

  1. Step 1: Preheat your oven to 300°F (150°C). In a small bowl, mix 2 tbsp ground wattleseed, 1 tbsp ground native pepperberry, 2 tsp sea salt, 1 tsp black pepper, and 4 minced garlic cloves.
  2. Step 2: Rub the 3 lbs bone-in lamb shoulder all over with 3 tbsp olive oil, then coat evenly with the wattleseed and pepperberry spice mix. Place 3 rosemary sprigs underneath the lamb in a roasting pan.
  3. Step 3: Cover the roasting pan tightly with foil and roast the lamb in the oven for 4 to 4.5 hours until the meat is tender and easily pulls apart with a fork.
  4. Step 4: Remove the foil, increase oven temperature to 425°F (220°C), and roast uncovered for an additional 15 minutes until the exterior forms a golden crust.
  5. Step 5: Let the lamb rest for 15 minutes before slicing or shredding to serve.
