Smoked Leg of Lamb

A muscle of lamb leg is slice on a chopping board showing the smoke ring and pink moist center.

A leg of lamb is traditionally roasted but this smoked version is moist, tasty, and totally worth trying. Smoking lamb offers another flavorsome way to prepare this meat.

There are limited commercial lamb rubs available so to get the best flavor out of the lamb this recipe includes a custom rub that has a lot more focus on the herbs than those rubs used on other meats.

Once cooked the lamb can be used as a main served with vegetables, or sliced thin and served in a taco with a parsley salad (tabbouleh). The lamb may be bone-in or have the bone-out, depending on what is available for you to buy.

    You don’t mention weight of lamb in your recipe smoking? You mention to cut Fat off, that’s the best part of Lamb, I dislike buying Lamb and all the fat cut off, irks me, I don’t care about calories, The fat on any meat is tastiest.

    1. Typically fat is cut off meat when smoking so the smoke has direct contact with the meat and a smoke ring can be formed. It can however be left on if that is your preference.
