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
- 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.
