Place all ingredients into a container and mix well together to combine.

Notes
1. How much rub to useYou want to cover the entire prime rib with an even layer of seasoning. The exact amount will depend on the size of prime rib you can cooking. For example, on a 10.5lbs prime rib I smoked, I used 3tbsp of rub.
