Ingredients
- 2 kg, bone-in lamb shoulder
- 3 tbsp, finely chopped fresh rosemary
- 2 tbsp, ground wattleseed
- 5, minced garlic cloves
- 4 tbsp olive oil
- 2 tsp salt
- 1 tsp black pepper
- 1 tbsp lemon zest
Instructions
- Step 1: Preheat oven to 300°F (150°C). In a small bowl, mix 3 tbsp finely chopped fresh rosemary, 2 tbsp ground wattleseed, 5 minced garlic cloves, 4 tbsp olive oil, 2 tsp salt, 1 tsp black pepper, and 1 tbsp lemon zest to form a fragrant rub.
- Step 2: Pat dry 2 kg bone-in lamb shoulder and rub the spice mixture all over, massaging it into the meat and under the skin where possible.
- Step 3: Place the lamb on a roasting rack in a roasting pan and cover loosely with foil.
- Step 4: Roast in the preheated oven for 4 to 4.5 hours, basting every hour with pan juices, until the meat is tender and easily pulls apart with a fork.
- Step 5: Remove foil in the last 30 minutes to allow the exterior to brown and crisp slightly before resting the lamb for 15 minutes to lock in juices.
