Ingredients

Instructions

  1. Step 1: Preheat oven to 300°F. In a small bowl, combine 2 tbsp ground wattleseed, 2 tbsp chopped rosemary, 1 tbsp chopped thyme, 4 minced garlic cloves, 3 tbsp olive oil, 2 tsp salt, and 1 tsp black pepper to form a fragrant rub.
  2. Step 2: Pat dry the 3 lbs bone-in lamb shoulder and massage the herb and wattleseed rub all over, ensuring even coverage.
  3. Step 3: Place the lamb in a roasting pan and add 1 cup water to the bottom to keep moist. Cover tightly with foil.
  4. Step 4: Roast in the oven for 3.5 to 4 hours, basting every hour with pan juices, until lamb is tender and easily shredded with a fork.
  5. Step 5: Remove foil and increase oven temperature to 425°F. Roast uncovered for 15 minutes to crisp the outer crust. Rest 15 minutes before slicing and serving.
