Instructions

1. Step 1: Preheat oven to 375°F. Using a sharp knife, make 12 small slits all over the 3 lb bone-in lamb leg and insert 6 thinly sliced garlic cloves into the slits.
2. Step 2: Rub the lamb all over with 3 tbsp olive oil, 3 tbsp chopped fresh rosemary, 2 tsp salt, and 1 1/2 tsp black pepper, ensuring an even coating. Drizzle 2 tbsp freshly squeezed lemon juice over the top.
3. Step 3: Place the lamb on a roasting rack in a baking dish and roast in the preheated oven for 1 hour 30 minutes to 1 hour 45 minutes, or until an internal temperature of 135°F is reached for medium-rare.
4. Step 4: Remove from the oven and cover loosely with foil. Let rest for 15 minutes before carving to allow juices to redistribute.
