Best Smoked Prime Rib

Smoked prime rib is the showpiece holiday roast that pulls the centerpiece job from the oven and hands it to the smoker. The dry rub is a simple savory build: paprika for color and gentle sweetness, salt and pepper, onion powder, and a teaspoon of cayenne for heat that wakes up the crust without overpowering the beef.

The whole technique is low and slow with indirect heat at 200 to 250°F (95 to 120°C). At that temperature, an 8 pound roast takes 3 to 4 hours to reach the medium rare target of 140°F (60°C) internal. The slow climb is what gives prime rib that uniform pink edge-to-edge instead of the grey-band-around-pink-center you get from a hot oven roast.

Crushed rosemary goes on three-quarters of the way through cooking, not at the start. This is intentional: rosemary added too early burns and turns bitter under long smoke, but added late infuses the meat with clean piney flavor in the last 45 minutes.

Pro Tips

• Use a probe thermometer rather than time; oven smokers and ambient temperatures vary widely and a few degrees of overshoot turns prime rib from medium rare to medium.
• Pull the roast at 135°F (57°C) and let it rest 20 minutes; carryover heat pushes it to a true medium rare 140°F (60°C).
• Use a mild fruit wood like cherry or apple; oak or mesquite at 4 hours will overwhelm the beef.
• Slice across the grain after resting; cutting too soon spills the juices.

Variations

• Add 2 teaspoons of granulated garlic to the rub for more depth.
• Substitute smoked paprika for regular paprika to deepen the bark flavor.
• Serve with horseradish cream and Yorkshire puddings for a classic prime rib spread.
