Description

A classic and elegant dish featuring a tender, juicy leg of lamb roasted with garlic, rosemary, and herbs—perfect for special occasions or holiday feasts.


Ingredients

Scale
  • 1 (5 to 6 lb) bone-in leg of lamb

  • 4 cloves garlic, sliced

  • 2 tablespoons fresh rosemary, chopped

  • 1 tablespoon fresh thyme, chopped

  • 2 teaspoons salt

  • 1 teaspoon black pepper

  • 2 tablespoons olive oil

  • 1 tablespoon Dijon mustard

  • ½ cup dry white wine or chicken broth

  • 1 onion, quartered

  • 2 carrots, chopped

  • 2 celery stalks, chopped


Instructions

  • Preheat oven to 400°F (200°C).

  • Using a sharp knife, make small slits all over the leg of lamb and insert garlic slices into the slits.

  • In a small bowl, mix rosemary, thyme, salt, pepper, olive oil, and Dijon mustard to form a paste. Rub evenly over the lamb.

  • Place the onion, carrots, and celery in the bottom of a roasting pan. Set a rack over the vegetables and place the lamb on the rack.

  • Pour the wine or broth into the bottom of the pan.

  • Roast for 20 minutes, then reduce the oven temperature to 350°F (175°C) and continue roasting for 1½ to 2 hours, or until the internal temperature reaches 135°F for medium-rare.

 

  • Remove from oven, tent loosely with foil, and let rest for 15–20 minutes before carving.


Notes

  • Use a meat thermometer for best results and to avoid overcooking.

  • For deeper flavor, marinate the lamb overnight with the herb paste.

 

  • Save pan drippings to prepare a rich gravy or jus.
