Ingredients

Scale
  • 4 to 5 pounds bone-in leg of lamb
  • 3 to 4 sprigs fresh rosemary, finely chopped
  • 4 to 5 cloves garlic, minced or pressed
  • 3 tablespoons extra virgin olive oil
  • 1½ teaspoons kosher or sea salt
  • 1 teaspoon freshly ground black pepper
  • Zest of one lemon (optional)
  • ½ cup white wine or broth (120 ml)

Instructions

  1. Remove the leg of lamb from the fridge about 45 minutes before cooking to bring it to room temperature.
  2. Trim any large excess fat from the lamb, leaving a thin layer for flavor. Score the fat in a crisscross pattern about ½ inch deep.
  3. In a small bowl, combine minced garlic, chopped rosemary, olive oil, salt, black pepper, and lemon zest to form a thick paste.
  4. Rub the garlic-rosemary paste all over the lamb, making sure to get it into the scored cuts.
  5. Preheat the oven to 275°F (135°C).
  6. Place the lamb on a rack in a roasting pan. Pour the white wine or broth into the bottom of the pan to keep the lamb moist.
  7. Insert a meat thermometer into the thickest part of the leg, away from the bone.
  8. Roast the lamb for about 3 to 3½ hours, or until the internal temperature reaches 135°F (57°C) for medium-rare or 145°F (63°C) for medium.
  9. Remove the lamb from the oven and tent loosely with aluminum foil. Let it rest for 20 minutes to redistribute the juices.
  10. Carve thin slices against the grain and serve.

Notes

Bring lamb to room temperature before roasting for even cooking. Use a meat thermometer to avoid overcooking. Let the lamb rest after roasting to keep it juicy. For a crispier crust, broil for 3-5 minutes at the end, watching carefully to prevent burning. If no rack is available, rest lamb on chopped onions or carrots.
