Every Thanksgiving I have been given the task of cooking a prime rib. This year I did 2 smaller primes and used a coffee-chilli rub on one and a santa-maria style rub on the other. I smoked the meat at 275 degrees until I had an internal temp of 125. I used hickory and oak chunks for the smoke. Once the meat reached 125 degrees internally I wrapped with foil and let rest for about an hour and half.


Prime rib 14 Pound (2 aboutt 7 pounds each)
For chilli coffee rub
Brown sugar 2/3 Cup (10.67 tbs)
Finely ground coffee 1/3 Cup (5.33 tbs) (dark roast coffee)
Kosher salt 1/2 Cup (8 tbs)
Chilli powder 1/3 Cup (5.33 tbs)
Cumin powder 1 Tablespoon
Ground garlic 2 Tablespoon
Paprika 1/3 Cup (5.33 tbs)
Granulated sugar 2 Tablespoon
Santa maria rib
Santa maria style rub 2 Tablespoon



1. Trim of the excess fat from the prime rib and make slightly deep slits on the meat to score the meat surface.

2. In a large bowl, put all the ingredients for the coffee chilli rub.


3. Sprinkle about 4 tablespoons of chilli coffee rub mixture over 1 of the prime rib and rub well to coat the meat.

4. Sprinkle the santa maria style rub over the other prime rib and spread well all over the meat.

5. Preheat the smoker to 275 to 300 F with hickory and oak wood.

6. Place both the prime ribs on the grill in smoker, cover and cook for about 2 ½ to 3 hours, checking the meat after every 1 hour.

7. After about 3 hours, or as the internal temperature reaches 125 F, take the meat off the grill.


8. Double wrap both the meats individually in a piece of foil and let them rest for about 1 ½ hours or until the internal temperature reaches 135 F.


9. Slice and serve as desired.
