🥘Ingredients

For the Lamb

1 boneless leg of lamb (about 4-5 pounds)
4 cloves garlic, minced
2 tablespoons fresh rosemary, chopped
2 tablespoons fresh thyme, chopped
2 tablespoons olive oil
1 teaspoon salt
1/2 teaspoon black pepper

For the Pan Gravy (Optional)

1 cup chicken broth
1 tablespoon all-purpose flour

👨‍🍳Directions

1Preheat your oven to 450°F (232°C).
2In a small bowl, combine the minced garlic, rosemary, thyme, olive oil, salt, and pepper to make a paste.
3Place the boneless leg of lamb on a cutting board and pat it dry with paper towels. Rub the garlic herb paste all over the lamb, making sure to coat it evenly.
4Place the lamb in a roasting pan, fat side up. Insert a meat thermometer into the thickest part of the meat.
5Roast the lamb at 450°F for 15 minutes to sear the outside. Then reduce the oven temperature to 325°F (163°C) and continue roasting until the internal temperature reaches 135°F (57°C) for medium rare, about 1 hour to 1 hour 15 minutes. For medium, cook to 145°F (63°C).
6Remove the lamb from the oven and let it rest on a cutting board for 15 minutes before slicing. The temperature will rise about 5 degrees during resting.
7While the lamb rests, make the pan gravy. Place the roasting pan on the stovetop over medium heat. Add the chicken broth and whisk, scraping up any browned bits from the bottom of the pan. If you want a thicker gravy, whisk in the flour and cook for 2 minutes until thickened.
8Slice the lamb against the grain and serve with the pan gravy.
