How to cook a boneless leg of lamb

Unlike most recipes for large cuts of meat, this one does not require any brining time. This leg of lamb just needs a simple herb rub that serves as a brief marinade right before it goes in the oven.

Which is better bone-in or boneless leg of lamb?

Bone-in leg of lamb is usually a little cheaper and cooks faster. Plus, you get a bone for making stock. The bone adds a little extra juiciness to the meat; however, boneless lamb roasts can be just as delicious and are much easier to carve without the bone.

Leg of Lamb Marinade Ingredients

  • Lamb Roast
  • 3 cloves garlic, minced
  • 2 teaspoons fresh rosemary leaves, coarsely chopped (1 teaspoon dry rosemary leaves)
  • 1/4 teaspoons ground black pepper
  • 1/2 cup olive oil, extra-virgin
  • 2 tablespoons lemon juice, fresh-squeezed

This recipe uses a blend of rosemary, garlic, and black pepper. Cumin, oregano, and curry are also popular seasonings for lamb.

You will also need a rack inside of a roasting pan, like the one below. If you do not have a pan like this, a deep casserole dish or dutch oven will also work. Cooking times may vary depending on these changes.

What size lamb roast should I buy?

This is a question I struggled with for a long time. My secret: always estimate more than what you need. I always account for about ½ pound of meat per serving. Most people don’t actually eat that much, especially if you are factoring in children.

With ½ pound per person, here’s a chart for getting the right size for the number of servings:

Lamb Roast Internal Cooking Temperatures

If you take nothing else away from this article, hear this: Please. Please. Please. Use an in-oven meat thermometer.

You can pick them up off of Amazon, Target, Wal-Mart, or just about any grocery store.

Internal temperature – not time – will yield the perfectly tender result that you want!

The internal temperature is all a matter of taste. Personally, I prefer lamb right at the threshold between Medium Rare and Medium. It’s still pretty pink in the center but not overly runny. The red juices, by the way, are not blood, but a protein in the meat that is released when cooked.

To reach your desired doneness and temperature, follow this chart:

LevelInternal Temp (F)Looks Like
Rare120-125FBright red center, pinkish toward exterior
Medium Rare130-135FPink center, slightly browned toward exterior
Medium140-145FLight pink center, outer portion is brown
Medium Well150-155FNot Pink
Well Done160F and aboveUniformly brown throughout

What is the cooking time for a leg of lamb?

Of course, the time it takes to reach the desired internal temperature is determined by the weight of the lamb roast.

Keep in mind that all ovens vary, which is why it’s so important to use an in-oven meat thermometer while cooking, so you can monitor the process.

As a general guide, refer to this chart when preparing estimates for cook time:

WeightRare
(120-125F)
Medium-Rare (130-135F)Medium
(140-145F)
Well Done (160-165F)

Tips for this recipe

  • After the roast is removed from the oven, it will continue cooking as it rests. The longer the meat rests, the higher the internal temperature will rise. Keep this in mind when you are calculating serving and cooking times.
  • If you do not have an in-oven thermometer, use a regular meat thermometer to begin checking the internal temperature about 30 minutes before the estimated roasting time ends.
  • Bringing the meat to room temperature is crucial for a well-roasted cut of meat. Otherwise, you could end up with a tough roast.

Servings 8 servings

Prep Time 10 minutes mins

Cook Time 3 minutes mins

Total Time 13 minutes mins

Ingredients

  • 3 cloves garlic (minced)
  • 2 teaspoons fresh rosemary leaves (coarsely chopped (1 teaspoon dry rosemary leaves))
  • ¼ teaspoons black pepper
  • ½ cup olive oil (extra-virgin)
  • 2 tablespoons lemon juice (fresh-squeezed)
  • 4 pound Boneless Leg of Lamb Roast

Instructions

Make the Herb Seasoning Rub:

  • Allow the uncooked lamb to come to room temperature – about 1 hour.

  • Combine the garlic, rosemary, black pepper, olive oil, and lemon juice in a small bowl. Whisk to combine, and set aside.

  • Preheat oven to 450 degrees F.

Prepare the Lamb:

  • Remove the lamb from the package, but keep the netting on. Pat the roast dry with paper towels, and place on a rack of a roasting pan.

  • Apply the rub on all sides of the lamb roast.

  • Insert an oven-proof meat thermometer into the center of the roast, making sure the tip of the probe is not exposed but inserted into the meat.

Roast the lamb:

  • Place the uncovered lamb roast in a 450F degree oven for 15 minutes to create a “seared” effect and a flavorful brown crust.

  • After 15 minutes, reduce the oven temperature to 325F degrees for the remaining 1 hour and 20 minutes of cook time. (uncovered; for a 4 pound roast to medium-rare)

  • Continue cooking until the meat thermometer reads 120F degrees. Remove from the oven and cover with aluminum foil. Allow to rest for approximately 15-20 minutes, or until it reaches the desired internal temperature. (see chart above)

  • As you are ready to carve, place the roast on a cutting board with a well to catch juices. Remove the netting with scissors.

  • With a carving knife, slice the meat across the grain into desired thickness. Serve immediately.

FAQs

Does lamb leg get more tender the longer you cook it? ›

The leg and rack of lamb are perfect for herb-crusting and oven-roasting; since the shank and shoulder are a bit tougher, they fare well in stews or braises—the long cook time allows them to significantly break down and become fork-tender.

Which cooking method is ideal for a leg of lamb? ›

Whether boneless or bone-in, the perfect leg of lamb should be either oven-roasted until blushing pink on the inside (with an internal temp around 130°F) or roasted long and slow for several hours until the meat is very tender and falls apart to internal temp around 175°F (I often use the slow cooker for that).

Do you sear a leg of lamb before roasting? ›

For the perfect roast lamb, we recommend seasoning the surface of the meat, and then searing it, especially fat side down in a pan before roasting. Why bother with searing? Contrary to some stories, searing is less about locking in moisture, and all about improving the flavour!

Which cooking method is most often used to cook whole or boneless lamb legs? ›

Roast it in a rack in a 275°F (135°C) oven until it hits 125° to 130°F (52 to 54°C) for medium rare, about three and a half hours. Remove from the oven and rest for 30 minutes while you increase the oven temperature to 500°F (260°C). Return it to the oven for 15 minutes to brown. Remove the twine, carve, and serve.

What tenderizes lamb? ›

Baking soda / bi-carb and cornflour/cornstarch are the secret ingredients that tenderise the lamb meat. It's a technique called “velveting” that is used by Chinese restaurants, and it's the reason why the meat in your favourite Chinese dishes are always so soft.

What spices go with lamb? ›

Fresh rosemary, fresh garlic, lemon zest, black pepper, and salt are simple but amazing flavors that pair amazingly with the lamb! Each of these ingredients adds its unique warmth and depth to enhance the flavor of the dish.

Do you wash a leg of lamb before cooking? ›

Washing beef, pork, lamb, or veal before cooking it is not recommended. Bacteria in raw meat and poultry juices can be spread to other foods, utensils, and surfaces. We call this cross-contamination. Some consumers think they are removing bacteria and making their meat or poultry safe.

Do I need to trim a leg of lamb before cooking? ›

You're not going to find too many bone-in legs of lamb at the grocery store. You have to order that from a butcher. Usually the fat cap is left on, but I wouldn't trim it down much. I'd leave it and score the fat in crosshatch marks, and then that fat makes it self-basting.

How do you keep a leg of lamb from drying out? ›

The juices need time to redistribute throughout the meat. Cut too soon and the juices will end up pooling on the cutting board, leaving you with a drier cut of meat. Follow this tip: For a more tender and juicy piece of lamb, allow the meat to rest for at least 15 minutes after removing it from the oven.

Should you baste a leg of lamb? ›

Baste the meat 2-3 times during cooking. Using a turkey baster or a large spoon, scoop the juices up from the corner of the pan, and drizzle back over the top of the joint.

Is it better to cook leg of lamb with bone or boneless? ›

A boneless leg is easier to carve, while bone-in can be a bit more difficult to slice. If you're looking for a more intense lamb flavor, bone-in is the way to go.

Should a leg of lamb be at room temperature before cooking? ›

It is important to let the meat come to room temperature before beginning to ensure it will cook through evenly. It is also imperative to let the meat rest after cooking, 20 minutes is sufficient.

Should I salt leg of lamb before cooking? ›

No matter how you decide to cook your beautiful cut of grass-fed lamb, seasoning is the essential first step. Start by setting your cut of lamb onto a wire rack set into a rimmed baking sheet and sprinkle generously on all sides with kosher salt.

Should I brown my lamb before slow cooking? ›

If you have an extra 10 minutes, it's often worth browning the meat before slow cooking it. Browning or searing the meat in a hot pan caramelises its surface, which can give the final dish a richer, deeper flavour and colour. The high temperatures also help to render the fat on the surface of your lamb.

How to make lamb more tender? ›

Slow-cooking lamb

Slow cooking in liquid transforms tougher cuts of lamb into fork-tender meat. Neck, shoulder and belly, either diced or as whole joints, are the best cuts for slow cooking and need to be cooked for at least 2 hrs at 150C to soften the meat.

Can you overcook a leg of lamb? ›

The level of doneness for lamb largely comes down to personal preference. Pull it out of the oven too soon and it may be too undercooked and unappetizing for your taste. When cooked for too long, this tender cut can be quick to dry out. A deeply browned crust won't cut it for figuring out whether your lamb is finished.

Why is my lamb still tough after slow cooking? ›

Slow cooking is a long process that requires patience. If your meat is still tough, it may simply need more time for the collagen-rich connective tissues to break down fully. Ensure you follow recipe guidelines for cooking times but remember, these can vary depending on the specific cut and size of the meat.

Why is my lamb tough and chewy? ›

Temperature is by far the most critical aspect of cooking lamb chops. Undercooking even tender lamb chops can render them unpleasantly chewy, while overcooking will lead to tough, dried-out meat. Rib chops should be cooked to about 130°F, while loin chops are better at 135°F or even 140°F.
