Instructions

  1. Step 1: Preheat oven to 375°F (190°C). In a small bowl, combine 2 tbsp chopped fresh rosemary, 1 tbsp fresh thyme leaves, 6 minced garlic cloves, 3 tbsp olive oil, 2 tsp kosher salt, 1 tsp freshly ground black pepper, and 1 tsp lemon zest to make a fragrant herb paste.
  2. Step 2: Pat dry the 4 lb bone-in leg of lamb with paper towels and rub the herb mixture all over the surface, pressing gently to adhere.
  3. Step 3: Place the lamb on a roasting rack in a shallow pan and roast in the preheated oven for 1 hour 20 minutes to 1 hour 30 minutes, or until a meat thermometer inserted into the thickest part reads 135°F for medium-rare.
  4. Step 4: Remove the lamb from the oven and tent loosely with foil; let rest for 15 minutes before carving to allow juices to redistribute.
  5. Step 5: Slice the lamb against the grain and serve warm with pan juices or your preferred sides.
