    Boneless Leg of Lamb

    Boneless leg of lamb is a leg that has been deboned for quicker cooking and ease of slicing and serving. You can purchase these from a local butcher or grocery store in the meat department. It’s almost 100% sold wrapped in a butcher’s twine netting so that it can hold its shape while cooking.

    There are many ways to prepare a boneless leg of lamb, whether in the oven or smoker and with assorted ingredients stuffed in it, served on it, or alongside it. My recipe is for a smoked boneless leg of lamb, but the procedures and temperatures can perfectly be applied to cooking in the oven, although there will not be any smoky flavors.

    Ingredients and Substitutions

    leg of lamb ingredients
    • Lamb – You will need a boneless leg of lamb for this recipe. However, these cooking procedures would also work for a bone-in leg of lamb.
    • Oil – I use the oil from my garlic confit recipe. You can use plain olive or avocado oil for this recipe.
    • Garlic – You will need roasted garlic or garlic confit cloves.
    • Herbs – I used a combination of fresh thyme, rosemary, and flat-leaf parsley. You can substitute 1 to 1 for dry ingredients.
    • Shallot – You will need a shallot for the sauce. However, you can substitute with a red, white, yellow, or sweet onion.
    • Stock – I used beef stock for the sauce.
    • Wine – Any cabernet sauvignon, merlot, shiraz, or blend is great.
    • Seasonings – I use only coarse salt and fresh cracked pepper.

    Chef Notes + Tips

    • Any dry red wine will work for the sauce.
    • You do not need to make the red wine brown sauce for this recipe.
    • Try cooking this on the smoker or in the oven like a smoked pork shoulder to where the meat easily shreds apart. To do this, cook it at 225° until it reaches 170° F internally and then wrap it in foil or butcher’s paper. Cook wrapped at 225° F until it reaches 204° F internally. Rest it for 25-30 minutes before unwrapping and shredding.
    • The pan sauce at the end is completely optional.
    • You can make this in the oven using the same temperatures. However, place the lamb on a rack inside of a pan. Do not place the leg of lamb directly on an oven rack. Use a pan.
