Ingredients
- 3 lbs, bone-in lamb shoulder
- 2 tbsp wattleseed, ground
- 2 tbsp fresh rosemary, chopped
- 4 cloves garlic cloves, minced
- 3 tbsp olive oil
- 2 tsp salt
- 1 tsp black pepper
- 1 tsp lemon zest
Instructions
- Step 1: Preheat your oven to 325°F. In a small bowl, mix 2 tbsp ground wattleseed, 2 tbsp chopped fresh rosemary, 4 minced garlic cloves, 3 tbsp olive oil, 2 tsp salt, 1 tsp black pepper, and 1 tsp lemon zest to form a paste.
- Step 2: Pat dry the 3 lbs lamb shoulder with paper towels and rub the wattleseed-rosemary paste all over the surface, pressing firmly to coat evenly.
- Step 3: Place the lamb shoulder on a roasting rack in a roasting pan and cook in the preheated oven for 3 to 3.5 hours, basting every hour with the pan juices, until the internal temperature reaches 195°F and the meat is tender and falling off the bone.
- Step 4: Remove the lamb from the oven and let it rest for 15 minutes before carving. Serve with roasted vegetables or mashed potatoes.
