One of the easiest and most flavorful ways to cook prime rib is on a pellet grill. This recipe will help set you up for success. It takes a little while to cook it perfectly but believe me, it is worth the wait!
Pull the prime rib out of the refrigerator an hour or two before you plan to cook it.
Mix together the seasonings, or use your favorite steak seasoning, and liberally season all of the sides of the meat.
Preheat smoker to 225℉.
Place the prime rib bone side down on the smoker. Cook for about 35 minutes per pound or 3-4 hours. The center should read 120℉ for a rare prime rib or closer to 130℉ for medium.
Place the prime rib on a cutting board or rimmed baking sheet. Tent it with foil and allow to rest for 20 minutes. Meanwhile, turn the smoker up to 400℉.
Return the roast to the smoker. Cook until the center is 130℉ for rare, 135℉ for medium-rare, or 140℉ for medium. Keep an eye on it, getting the correct temperature is really important.
Rest for 15 minutes before slicing. Run a knife along the bones to remove them from the meat to make slicing easier.
