Instructions

  1. Step 1: Preheat the oven to 375°F. Pat dry 3 pounds of baby lamb leg and score the surface lightly with a sharp knife to allow flavors to penetrate.
  2. Step 2: Rub 3 tablespoons of olive oil evenly over the lamb leg, then massage 2 teaspoons sea salt, 1 teaspoon black pepper, and 1 teaspoon lemon zest all over the meat.
  3. Step 3: Insert 6 smashed garlic cloves and 4 fresh rosemary sprigs into the scored cuts on the lamb leg to infuse aromatic flavor.
  4. Step 4: Place the lamb leg on a roasting rack in a shallow pan and roast in the preheated oven for 1 hour and 15 minutes for medium-rare, or until an internal temperature of 135°F is reached.
  5. Step 5: Remove the lamb from the oven and tent loosely with foil. Let rest for 15 minutes to allow juices to redistribute before slicing and serving.
