Ingredients
Herb and Garlic Mixture
- 1/3 cup olive oil
- 3 tablespoons finely minced fresh thyme
- 3 tablespoons finely minced fresh rosemary
- 3 tablespoons finely minced fresh parsley
- 15 cloves garlic, finely grated
Prime Rib and Seasoning
- 8 pound boneless ribeye roast
- 1 ½ tablespoons sea salt
- 1 tablespoon black pepper
- 3 tablespoons olive oil (for coating roast)
Instructions
- Preheat smoker: Set your smoker to a temperature between 225° and 235°F to prepare for low and slow smoking of the prime rib.
- Prepare herb mixture: In a medium bowl, mix 1/3 cup olive oil with thyme, rosemary, parsley, and garlic. Reserve one-third of this mixture to use later in the recipe.
- Trim fat cap: Trim any unwanted fat off the prime rib roast, leaving some fat for flavor and moisture during cooking.
- Coat roast with oil: Rub the roast on all sides with the remaining 3 tablespoons of olive oil to help the seasoning adhere.
- Season roast: Generously sprinkle sea salt and black pepper evenly on all sides, pressing the seasoning into the meat.
- Apply garlic and herb crust: Coat the roast thoroughly with two-thirds of the garlic and herb mixture, covering all surfaces.
- Place roast in smoker: Position the roast on the top rack of the smoker. Insert a digital thermometer into the center of the meat for accurate temperature monitoring.
- Prepare drip pan: Place an aluminum pan underneath the roast to catch drippings during the smoking process.
- Smoke at low temperature: Smoke the prime rib at 225° to 235°F until the internal temperature reaches 100°F, approximately 2 ½ to 3 hours.
- Increase temperature to finish: Raise the smoker temperature to 500°F and continue cooking until the roast reaches an internal temperature of 118° to 120°F for perfect medium-rare doneness.
- Rest and apply remaining crust: Remove the roast from the smoker, spread the reserved one-third garlic and herb mixture on top, and let it rest for 20 minutes to allow juices to redistribute.
- Slice and serve: Cut the prime rib into slices and serve with au jus and creamy horseradish sauce for a classic accompaniment.
Notes
- Use a digital thermometer to monitor the internal temperature accurately for perfect doneness.
- Adjust smoking times based on your roast size and smoker performance.
- Allow resting time after smoking to keep the meat juicy and tender.
- Serve with complementary sides like roasted vegetables or mashed potatoes.
- Save the drippings collected in the aluminum pan to make delicious au jus.
