How to Smoke A5 Prime Rib


  • A5 Prime Rib
  • Hardwood charcoal (oak, hickory, sugar maple, etc.)
  • Dijon mustard or mayonnaise (if making a spiced crust)
  • Salt and pepper
  • 25 garlic cloves (approximately 3 heads)


  1. Heavily season exterior with salt and pepper prior to cooking. Seasoning it overnight is preferable, but at minimum, 60 minutes prior to cook start.
  2. For a spiced crust, use a Dijon mustard or mayonnaise to help herbs affix to roast and form crust.
  3. Stud top of roast with garlic cloves.
  4. Grill at 250 to 300°F, keeping the heat below 300.
  5. Smoke for 3.5 hours until it hits an internal temperature of 140°F for medium, 135°F for medium-rare.
  6. Allow it to rest 3 minutes per pound. Do not cover with foil. Leave uncovered to retain superior crust.
