  • 5 lb boneless prime rib roast tied back
  • 1 Tbsp ground black pepper
  • 2 tsp garlic powder
  • 2 tsp dried rosemary
  • 1 tsp onion powder
  • 2 Tbsp brown sugar
  • 2 Tbsp kosher salt
  • 2 tsp dried thyme leaves


  • Trim any excess fat from the top of the roast, down to about 1/4'' thick.
  • In a small bowl combine everything except the prime rib. Stir to combine. Rub the seasoning mixture all over the prime rib. Tie back prime rib if this is not done with butchers twine. Let sit at room temperature for one hour.
  • Preheat your electric pellet grill according to manufacturers directions to 225 degrees.
  • Place the roast on the electric smoker fat side up and close the lid. Smoke until the internal temperature is 120 degrees F. for rare or 130 degrees F for medium. This will take about 3 1/2 hours.
  • Remove the roast to a cutting board and tent with foil. Allow to rest for 15 minutes. Remember it will continue to cook and rise an additional 5 degrees while it rests. Slice and serve immediately.


How many minutes per pound do you smoke a prime rib?
About 30 minutes per pound for medium rare. Rely on your meat thermometer for testing the temperature.
Here’s a quick overview of the correct internal temperature range:
  • Rare: 120-125 degrees F
  • Medium Rare: 130-135 degrees F
  • Medium: 135-140 degrees F
  • Well Done: 145 degrees F or higher
Remember you will want to pull the prime rib from your smoker when it reaches an internal temperature 5 degrees less than your desired ending temperature. This is because it will continue to cook as it rests bringing it up to your desired temperature.
How much per person?
You’ll want to plan about a pound per person. This is because you’ll have some loss when you trim and cook the prime rib. If you have a lot of kids in your group you could plan about 3/4 lb per person since their appetites are smaller.
What wood chip should I use?
You’ll definitely want to use a mild flavor of wood chip when smoking this cut of meat. We prefer using an apple wood chip. This will give it a mild, slightly sweet flavor without overpowering it. Another great option would be a cherry flavor.
