Lamb is a great source of protein, minerals, and essential vitamins. Serving this up to your family, you know they will be getting all this wonderful nutrition in a gorgeous meal fit for the finest of Sunday suppers. Both the marinade and herb crust have easily accessible ingredients, most you may have on hand.

What Goes Into Making a BBQ Leg of Lamb?

Ontario Lamb is produced locally by almost 4,000 committed farmers to give you a fresh and quality product, something you will be proud to serve.

This recipe is packed with flavor from herbs like fresh rosemary, oregano, and thyme. You can get amazing flavors equally from a gas grill or a charcoal grill, whatever your preference.

For a big leg of lamb like this, you get well done to medium or medium-rare as you slice into the leg. With the delicious herb crust on the outside, everyone gets a little of that. Served up with any sides you like, this lamb is an exquisite meal to be enjoyed by family and friends.

How to Grill a Leg of Lamb

The first step in the process is to make the marinade for your leg of lamb. Add the olive oil, white wine, garlic, oregano, rosemary, thyme, kosher salt, juice of a lemon, and whole peppercorns to a large dish or extra large storage bag.

Stir to make sure that all the ingredients are combined. Lay the lamb in the dish or place it in the bag and turn to coat all sides. Cover with plastic wrap and marinate in the refrigerator for 12 – 24 hours. Make sure you turn the lamb occasionally while it is marinating.

After the lamb has marinated, it’s time to make the herb rub. Mix the oregano, rosemary, thyme, parsley, minced garlic, Dijon mustard, olive oil, and Kosher salt in a small bowl. Stir the herb mixture until you have a paste.

Using a paper towel, lightly dry the lamb. Rub the herb paste all over the lamb, covering both sides of the roast.

Make sure you allow time for your lamb to come up to room temperature. This will significantly reduce cooking time and give you a better outcome.

Set up your grill for indirect cooking. You want one side of your grill to be hot and the other side of the grill to not have any heat under it.

How Long to Grill a Leg of Lamb

Place the leg of lamb on the hot side of the grill over the direct heat. Sear on all sides; you want the outside to be nicely charred, giving you an altogether marvelous flavor. Then move the lamb over to the cool side of the grill and cook with the lid closed using indirect heat for 1 1/4 to 1 3/4 hours.

What temperature do you cook lamb on a gas grill? You want to BBQ the lamb until the internal temperature reaches about 140 degrees F. in the thickest part, using an instant-read thermometer.

Thermapen

How do you check to see if it is done perfectly? Undeniably, I use my easy-read Thermapen; it gives you a very accurate instant temperature. Cook to 140F and then let rest for 15 min.

Time to Serve The Lamb

Once you remove the lamb from the grill, you need to let it rest for at least 15 minutes before you start slicing into it. Therefore this time resting allows the juices to be reabsorbed into the meat.

If you start slicing the lamb as soon as it comes off the BBQ, you will lose much of the juices in the roast, resulting in a dry leg of lamb.

Lastly, once it is rested, now it is time to start slicing your lamb. Your leg of lamb should be medium-rare to medium, just, and pink in color. I like to slice the lamb fairly thin; I find it is easier to eat than a thick slice of lamb.

Look at how juicy, tender and delicious this cooked lamb looks. The lamb is first grilled directly to get that awesome charred crust, then slowly roasted on indirect heating until cooked to desired doneness.
