Ingredients

Instructions

  1. Step 1: Preheat the oven to 325°F. Rub 3 lbs bone-in lamb shoulder all over with 2 tbsp olive oil, 1 1/2 tsp salt, 1 tsp black pepper, and 4 minced garlic cloves.
  2. Step 2: Place the lamb in a roasting pan and tuck 3 rosemary sprigs around it. Pour 1 cup water into the bottom of the pan to keep the meat moist.
  3. Step 3: Roast the lamb uncovered for 3 hours, basting every hour with the pan juices.
  4. Step 4: In the last 30 minutes of roasting, combine 1/2 cup bush tomato chutney and 2 tbsp ground wattleseed in a small bowl. Brush this glaze evenly over the lamb.
  5. Step 5: Continue roasting uncovered until the glaze caramelizes and lamb is fork-tender.
  6. Step 6: Let the lamb rest for 15 minutes before slicing. Serve with the pan juices spooned over the top for a rich, Australian-inspired feast.
