Sliced Leg of Lamb and Red Potatoes

Boneless Leg of Lamb.

You will notice a few options when buying lamb. If you are at a market, butcher, or grocery store you usually have three options. A bone in leg of lamb, a boneless leg of lamb that has been tied or placed in a netting, and a leg of lamb the is butterflied open and boneless. Each piece has its positives and uses.

For this recipe, I will be using a boneless leg of lamb that is bound together in netting without the bone. Some folks prefer the bone to stay in which can be argued add flavor and has a nice presentation at the table. If you prefer bone in go for it. Just watch your cooking times. Bone in will require longer on the grill.

I like boneless in the netting for an even temperature throughout the lamb.

What seasonings go with lamb?

This recipe has two classic seasonings that go hand in hand with lamb. The entire lamb is covered with garlic powder and rosemary. If you prefer fresh garlic and rosemary you can make slits with  a small knife and shove pieces of fresh garlic into the meat. You can also place rosemary springs against the outside of the meat as they will hold steady because of the netting.

Should I marinate lamb?

You have the option to marinate a leg of lamb but this recipe does not call for it. Lamb is a tender piece of meat that does not need a marinade assisting with the breakdown of the fibers. Also, you want seasonings to compliment the meat, not mask the flavor. A heavy marinade may just do that. So, if you do decide to marinate you lamb leg only do do for a short period of time such as an hour.

How do you roast Lamb on the Grill?

Let your lamb sit out of the refrigerator for 45 minutes. You want to bring it up to room temperature. This will help with even cooking while on the grill. You want the lamb leg evenly cooked edge to center. What you don’t want is a well done edge and a super pink middle.

Preheat your gas grill to 275 degrees F. Place the lamb away from the direct heat fat side up. This way the fat slowly melts into the lamb and helps with keeping the lamb leg moist. Also, slowly cooking the lamb fat adds a nice layer of flavor to the meat because the fat turns nice and crisp while slow roasting.

After a half hour on the grill rotate the lamb so the other side of the meat is facing the flame. This helps with even grilling.

How long do you roast a boneless leg of lamb?

At 275 degrees F this lamb recipe is based on roasting low and very slow. The reason for the low temp instead of a quicker roast at 350 degrees is keeping an even temp throughout the leg of lamb. In my opinion the best piece of lamb is nice and tender that has been slowly brought up to temperature. Keeping the temp too high allows the outside edges of the lamb to be cooked at a higher temp causing too much well done areas on the outer edges of the meat. You want to keep as much meat at a nice medium rare perfection!

Once the lamb is on the grill close the lid and leave it be. Opening the lid often will delay the grilling process. How long you roast your lamb on the grill depends on the size and internal temperature you are looking for. Check the internal temp of the lamb after an hour grilling. Remember keep the lamb away from the direct heat. After an hour of grilling check the temperature of the lamb often. You don’t want to overcook and take the temp into the medium well or well done range.

Average size boneless lamb leg that you can buy that would serve 6 to 8 people would be 4 pounds. I prefer bringing the temperature up to 125 degrees F and then take it off the grill.

Once off the grill the lamb will continue to rise in temperature and hit 130 degrees F. This should be a nice medium rare. If you prefer rare I would take the lamb off at 120 degrees and let it sit. 125 degrees F should be a really pink middle and rare. Let the lamb sit for a half hour then slice. If you are looking for above a medium temperature for leg of lamb go check out another website. I won’t assist with that mistake!

After the lamb has properly sat and you slice up the leg, sprinkle some kosher salt over the sliced lamb.

What side dishes go well with leg of lamb?

You have a lot of options for side dishes with lamb but I’ve always been a fan of small red potatoes. I roast them next to the lamb on the grill with some olive oil and salt.
