This easy homemade Prime Rib Rub is made with kosher salt, rosemary, thyme, garlic powder, coarse pepper, and smoked paprika. Use it to season prime rib for the oven, Traeger, or smoker, and let it sit overnight for the best flavor.
Place all ingredients in a bowl and stir to combine.
Pat prime rib dry with a paper towel. Sprinkle seasoning over the prime rib to evenly coat all sides. Spread the rub with your fingers and massage into the meat a bit. Tightly wrap in plastic wrap and refrigerate for 12-24 hours before cooking.
