Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F (160°C). In a small bowl, mix 1 tbsp ground bush pepper, 1 tsp ground dried eucalyptus leaves, 2 tsp sea salt, 4 minced garlic cloves, 2 tbsp chopped fresh rosemary, and 1 tbsp lemon zest.
  2. Step 2: Rub the 1.5 kg bone-in lamb shoulder all over with 3 tbsp olive oil, then coat thoroughly with the bush pepper and eucalyptus mixture.
  3. Step 3: Place the lamb in a roasting pan and roast in the preheated oven for 3 hours, basting every hour with the pan juices, until the meat is tender and easily pulls apart.
  4. Step 4: Remove from oven and let rest for 15 minutes before carving to allow juices to redistribute.
  5. Step 5: Serve slices of the lamb with the pan juices spooned over for a fragrant, flavorful roast.
