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

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.

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).

Should you sear 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!

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

Braising: Braising involves searing the lamb leg roast in a hot pan and then cooking it slowly in liquid (such as stock or wine) in a covered dish. The moist heat from the liquid helps keep the roast moist and tender. Roasting with a crutch: Wrap the lamb leg roast in foil or place it in a roasting.

Is boneless leg of lamb tough? ›

The leg and rack are the most tender cuts of meat on a lamb, and are at their best when roasted. Roasting is a "dry heat" cooking method, meaning that you do not add any liquid to the meat as you cook it. Tougher cuts of lamb, such as shank and shoulder, are best for braising and stewing.

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.

Do you rinse leg of lamb before cooking? ›

There is no need to rinse raw lamb before cooking because this creates a cross-contamination hazard and is not necessary.

What temperature should a boneless leg of lamb be cooked to? ›

Use an instant read thermometer to be sure that you pull it from the oven at the proper time, 10˚F before it reaches your desired temperature as the cooked meat's internal temperature will rise after you remove it from the oven). Target temperatures: Medium-Rare 145˚F, Medium 160˚F, Well-Done 170˚F.

Do you cook leg of lamb fat side up or down? ›

Place the lamb on the smoker, fat-cap side down. (This will help protect the meat from any direct heat. If cooking in an offset smoker, place the lamb fat-side up.) Insert Signals' probe into the very center of the meat.

What happens if you don't sear a roast before cooking? ›

The meat will cook just fine without searing. (And any surface bacteria will die during cooking anyway.) But I really believe that the depth and complexity of flavor we gain in this searing step is well-worth the extra effort.

Should lamb be cooked slow or fast? ›

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.

Should I prepare lamb night before? ›

Instead of cooking to prepare lamb for service, any cut of boneless lamb can be thinly sliced and tossed in a bowl with a small amount of bicarb soda and corn starch then chilled to tenderize. For our quick cuts 1-2 hours is enough, but our shoulder and leg cuts would need at least 8 hours or overnight.

Why is leg of lamb tough? ›

When meat is sliced with the grain, it often results in tougher, chewier pieces. Follow this tip: The grain of the meat refers to the direction in which the muscle fibers run. Always slice lamb against the grain, cutting across the muscle fibers rather than with them.

Does lamb cook better on the bone? ›

It all starts with the buying, you should decide whether you're going to get a boneless leg of lamb, or one with the bone kept in. Boneless legs are easier to carve, but a leg of lamb with the bone will have a stronger flavour and will retain the heat well (which will cause it to cook quicker).

Is lamb better on the bone? ›

To maximise the flavour, cook lamb shoulder on the bone so the meat simply falls apart when pulled with a fork. Recipes using lamb shoulder are fail-safe crowd pleasers – try this slow-cooked shoulder with roasted vegetables for a perfect Sunday lunch or roast in fragrant spices for a more feisty dish.

Does boneless cook faster than bone in? ›

First, boneless meat will cook faster. There is less muscle and connective tissue to deal with, and the bone isn't slowing down the transfer of heat. This means that you can prepare a meal in less time, which is helpful if you prefer something quick and easy.
