How to Make Roast Leg of Lamb
Preheat Oven: Start by preheating your oven to 325°F (165°C). This temperature is perfect for low and slow cooking, ensuring a juicy roast with a crispy crust.
Prepare the Rub: In a bowl, mix together 1/4 cup of olive oil, 8 minced garlic cloves, 1/4 cup of chopped fresh rosemary, 3 tablespoons of Dijon mustard, 1 1/2 teaspoons of kosher salt, and 1 teaspoon of ground black pepper until you have a smooth paste.
Apply Rub: Generously coat the leg of lamb with the herb rub, making sure every side is covered. Let it rest at room temperature for 30 minutes to allow the flavors to meld.
Roasting: Place the herb-rubbed lamb in a roasting pan. Roast for approximately 1.5 to 2 hours or until the internal temperature reaches 130°F (54°C) for medium-rare. Aim for a beautifully browned exterior!
Resting: Once the lamb is out of the oven, tent it loosely with foil and let it rest for about 15-20 minutes. This allows the juices to redistribute, resulting in tender meat.
Make Gravy: In the same roasting pan, pour in 2 cups of chicken broth and 1 cup of white wine, scraping up any browned bits. Stir in 1 tablespoon of flour and simmer until thickened, about 5-7 minutes.
Serve: Slice the lamb against the grain and drizzle with the rich gravy. Pair with seasonal sides for a feast that is truly memorable!
Optional: Garnish with fresh chopped parsley for a pop of color!

Expert Tips for Roast Leg of Lamb
- Resting Period: Allow the lamb to rest after roasting for at least 15-20 minutes to ensure succulent meat; this step is crucial for flavor and tenderness.
- Use a Meat Thermometer: For perfect doneness, aim for an internal temperature of 130°F for medium-rare; this avoids undercooking or overcooking your roast leg of lamb.
- Tie the Meat: If you re using a boneless cut, tying it with kitchen twine promotes even cooking and lends a beautiful shape to your roast.
- Herb Substitution: If you don t have fresh rosemary, feel free to swap it with fresh thyme or oregano; these herbs also work wonderfully with lamb.
- Don’t Skip the Sear: For an extra crispy crust, consider searing the lamb in a hot pan before roasting; it enhances the flavor and texture.
- Gravy Perfection: To achieve a thick and velvety gravy, ensure you whisk in flour well and scrape the bottom of the pan to capture all the flavorful bits.
