Instructions

  1. Step 1: Preheat oven to 300°F. In a small bowl, mix 2 tbsp ground wattleseed, 1 tbsp dried rosemary, 4 minced garlic cloves, 3 tbsp olive oil, 2 tsp salt, and 1 tsp black pepper to form a paste. Rub this mixture evenly over the entire 3 lb lamb shoulder.
  2. Step 2: Place the lamb shoulder in a roasting pan and tuck 4 thyme sprigs around it. Pour 1 cup water or stock into the pan to keep meat moist during roasting.
  3. Step 3: Slow roast the lamb in the oven for 4 hours, basting every hour with pan juices, until the meat is tender and falling off the bone.
  4. Step 4: While the lamb roasts, toss 4 peeled and chunked carrots, 3 peeled and chunked parsnips, and 2 peeled and chunked sweet potatoes with 1 tbsp olive oil and a pinch of salt and pepper. Spread them on a baking sheet and roast at 400°F for 35-40 minutes, turning halfway, until golden and caramelized.
  5. Step 5: Remove lamb from oven, let rest for 15 minutes, then carve and serve alongside the roasted root vegetables.
