Ingredients
- 3 lbs bone-in lamb leg
- 2 tsp wattleseed, ground
- 3 tbsp fresh rosemary, chopped
- 4 cloves garlic cloves, minced
- 3 tbsp olive oil
- 2 tsp salt
- 1 tsp black pepper
- 1/2 cup water
Instructions
- Step 1: Preheat oven to 375°F (190°C). In a small bowl, combine 2 tsp ground wattleseed, 3 tbsp chopped fresh rosemary, 4 minced garlic cloves, 3 tbsp olive oil, 2 tsp salt, and 1 tsp black pepper to form a thick paste.
- Step 2: Rub the wattleseed and rosemary paste all over the 3 lbs bone-in lamb leg, ensuring even coverage.
- Step 3: Place the lamb on a roasting rack in a roasting pan and pour 1/2 cup water into the bottom of the pan to keep the meat moist.
- Step 4: Roast in the preheated oven for 1 hour 20 minutes to 1 hour 30 minutes, or until the internal temperature reaches 135°F (57°C) for medium-rare.
- Step 5: Remove the lamb from the oven, tent with foil, and let rest for 15 minutes before carving to allow juices to redistribute.
