What You’ll Need
For this magnificent roasted leg of lamb, you’ll be working with a beautiful boneless leg of lamb, an abundance of fresh garlic and rosemary, a touch of olive oil, and simple seasonings. The water added to the roasting pan creates a gentle steam to help keep the lamb incredibly moist.
Ingredient Notes
- Boneless Leg of Lamb – A 5-pound boneless leg of lamb provides a generous portion, perfect for gatherings. Opt for one with a good amount of marbling for extra flavor and tenderness.

- Parsley – Fresh parsley adds a bright, herbaceous note that complements the richness of the lamb beautifully.
- Rosemary – This classic pairing with lamb brings a wonderfully aromatic and slightly peppery essence to the dish.
- Kosher Salt – Using kosher salt allows for easy adherence and provides a clean, briny flavor. The guideline of 1 teaspoon per pound is a great starting point for well-seasoned meat.
- Black Pepper – Freshly ground black pepper offers a pleasant warmth and subtle spice.
- Olive Oil – A good quality olive oil is perfect for both helping the seasonings adhere and for achieving that lovely golden crust.
- Water – A small amount of water in the bottom of the roasting pan creates steam, which is crucial for keeping the lamb incredibly moist as it roasts.
Add-ins and Substitutions
While this recipe is wonderfully classic as is, you can always personalize it! For an extra layer of flavor, consider adding a few sprigs of fresh thyme alongside the rosemary and parsley when seasoning the inside of the lamb. You could also add a few quartered onions or carrots to the bottom of the roasting pan to absorb some of the delicious pan drippings.
How to Make Roasted Leg of Lamb with Garlic
Creating this stunning roasted leg of lamb is a straightforward process that yields spectacular results. We’ll start by preparing the lamb, infusing it with flavor, and then letting the oven work its magic.
- Prepare and Season the Lamb: Begin by preheating your oven to 450°F (230°C) and positioning an oven rack in the center. Take your boneless leg of lamb and trim away any excess fat from the inside. Pat the lamb thoroughly dry with paper towels – this step is key for achieving a beautiful sear. Lay the lamb open on a cutting board. Drizzle about half of the olive oil over the inside surface. Evenly distribute half of the kosher salt, black pepper, and chopped rosemary over the oiled surface, followed by all of the minced garlic and parsley.
- Roll and Tie: Carefully roll the lamb into a neat cylinder. Securely tie it at 1- to 2-inch intervals using kitchen twine. This ensures the lamb cooks evenly and holds its shape.
- Sear and Season the Exterior: Make small, shallow cuts all over the exterior of the rolled lamb. Gently tuck the roughly sliced garlic cloves into these cuts. Brush the entire outside of the lamb with the remaining olive oil. Evenly sprinkle the rest of the kosher salt, black pepper, and rosemary over the oiled exterior.
- Roast to Perfection: Place the prepared lamb on a wire rack set inside a roasting pan. Pour the 1 1/2 cups of water into the bottom of the roasting pan, ensuring the water level stays below the lamb itself.
- Place the lamb in the preheated 450°F (230°C) oven for 15 minutes.
- After 15 minutes, reduce the oven temperature to 350°F (175°C).
- Continue roasting. The approximate cooking time is about 15-20 minutes per pound. You are aiming for an internal temperature of 130°F (54°C) when measured with a meat thermometer in the thickest part of the lamb, after it has rested.
-
Rest and Serve: Once the lamb reaches your desired internal temperature, carefully remove it from the oven. Transfer the lamb to a clean cutting board and loosely tent it with aluminum foil. Let it rest for 10 to 15 minutes. This crucial resting period allows the juices to redistribute throughout the meat, ensuring a tender and moist result. After resting, remove the kitchen twine and slice the lamb into generous portions.
-
Pro Tip: Don’t skip the resting step! It’s absolutely vital for locking in the juices and achieving that incredibly tender texture we all crave.
Recipe Tips
- Dry is Best: Make sure to pat the lamb thoroughly dry with paper towels before seasoning. This helps create a better sear on the outside.
- Even Cooking: Tying the lamb securely with twine helps it maintain a uniform shape, promoting more even cooking throughout.
- Thermometer is Your Friend: For the most accurate doneness, use an instant-read meat thermometer. Insert it into the thickest part of the meat, avoiding any large pockets of fat.
- Pan Juices: The water in the bottom of the pan will create flavorful drippings. You can use these to create a simple pan sauce or gravy if desired.
FAQs
- How long does it take to roast a leg of lamb?
The cooking time is approximately 15-20 minutes per pound at 350°F (175°C) after the initial high-heat sear. A 5-pound leg will typically take around 1.5 to 2 hours of roasting time, not including the initial 15 minutes at a higher temperature or the resting period. Always rely on an internal thermometer for accuracy. - Can I prepare the lamb ahead of time?
You can prepare the lamb, including seasoning and tying, up to a day in advance. Cover it tightly and store it in the refrigerator. Allow it to sit at room temperature for about 30 minutes before roasting. - What internal temperature should I aim for?
For a perfect medium-rare, aim for an internal temperature of 130°F (54°C) after resting. The temperature will rise slightly during resting.
Serving Suggestions
This glorious roasted leg of lamb is wonderfully versatile. It pairs beautifully with a variety of classic sides. Consider serving it alongside fluffy mashed potatoes, roasted root vegetables like carrots and parsnips, or a fresh, vibrant green salad. A dollop of mint sauce or a rich gravy made from the pan drippings would also be exquisite accompaniments. For a lighter option, serve with couscous or quinoa and a side of steamed asparagus.
Make This Recipe in Advance
You can certainly get a head start on this recipe! The leg of lamb can be trimmed, seasoned, rolled, and tied up to 24 hours in advance. Cover it tightly with plastic wrap or place it in an airtight container and store it in the refrigerator. When you’re ready to cook, remove the lamb from the refrigerator about 30 minutes prior to roasting to allow it to come closer to room temperature, which helps ensure more even cooking. The resting period after cooking is essential and should not be skipped.
