What You’ll Need:

  • Fresh rosemary-substitute with thyme, fresh marjoram, or fresh oregano
  • Fresh Thyme
  • Salt and black pepper

Since the leg of lamb is boneless, it will contain a meatier surface. Plan seasonings accordingly depending on the size thickness of the roast. Trim up any thick pieces of fat and small stray pieces of meat from the roast. Don’t over trim it. You will need a layer of fat to help keep lamb leg juicy. Next, use a sharp knife to lightly score the fat by making diagonal cuts in one direction, then the other. This will create a diamond pattern.

 Tying the Lamb:

Combine the rub mixture and apply some on the inside portion of the lamb roast. Set aside the remaining rub. Carefully roll roast back into position and truss with kitchen twine. The object is to close the roast up, so it stays in a compact, uniform shape as it cooks. Apply the remaining rub to the outside of the roast. Let sit at room temperature while the pellet grill heats up.

 

Cooking the Lamb Leg:

Preheat pellet grill to 325 degrees F. Place tied leg of lamb into the grill. If you have a temperature probe, push it into the center of the meat and cook to desired doneness, or 15 to 20 minutes of cooking time per pound of meat.

Pull lamb off the grill when it reaches an internal temperature of 125 degrees F, for medium-rare, 135 degrees F, for medium, and 145 degrees F, for well done. 

Remove roast, place it onto a clean cutting board, and cover with aluminum foil for 10 minutes. This will allow the temperature to continue rising 5-10 degrees more. Ideally, it is safe to consume lamb at 145 degrees F., but for this recipe, I recommend aiming for a medium pull temperature of 150, with a rising temperature between 155-160. Using a sharp knife of kitchen shears remove kitchen twine.

 

Slice roast into 1/2″ thick slices and serve.
