Indulge in a show‑stopping Garlic Prime Rib that’s bursting with bold Louisiana flavor by @GrillNation! Roasted to perfection, this prime rib delivers a mouthwatering balance of garlicky depth and Tony Chachere’s flavor.

Ingredients

  • For The Prime Rib:

  • 1 whole bone-in prime rib (4-7 bones, 8-14 lbs)

  • Tony Chachere’s Roasted Garlic Herb Injectable Marinade

  • 3-4 Tbsp Tony Chachere’s More Spice Seasoning

  • 1 Tbsp garlic powder

  • 1 Tbsp onion powder

  • 1 Tbsp smoked paprika

  • 1 tsp rosemary

  • 1 tsp thyme

  • olive oil or butter (to use as binder)

  • For The Cajun Honey Butter Baste: 

  • 4 Tbsp unsalted butter

  • 2 Tbsp honey

  • 1 tsp Tony Chachere’s More Spice Seasoning

  • 1 tsp minced garlic

  • Clear

Directions

  1. Inject the Prime Rib: Inject the roast thoroughly using Tony Chachere’s Roasted Garlic Herb Injectable Marinade, hitting multiple spots throughout the muscle for full flavor and moisture.
  2. Season the Prime Rib with Cajun Dry Rub: Coat the roast lightly with olive oil or melted butter. Mix Tony’s More Spice, salt, pepper, garlic, onion, paprika, thyme, and rosemary. Season the entire roast generously. (Optional: Refrigerate uncovered 2–12 hours for a dry brine.)
  3. Preheat the Smoker: Set the smoker to 250°F using hickory, oak, or pecan wood chips. Place a drip pan underneath with onions, garlic, herbs, and a splash of beef broth.
  4. Smoke the Prime Rib: Place the roast bone-side down and fat cap up. Smoke until internal temp reaches 115–118°F for medium-rare. About 25–30 minutes per pound.
  5. Cajun Honey Butter Baste: Melt butter, honey, garlic, and Tony’s More Spice. Baste the roast every 45–60 minutes during the smoke for a deep Cajun caramelized crust.
  6. Reverse Sear for Crust: Once internal temp hits your pull target, remove roast and increase grill or oven to 500°F. Sear 7–10 minutes until the exterior is browned and crisp. (Final temps: 125°F – Medium Rare, 135°F – Medium, 145°F – Medium Well)
  7. Rest the Roast: Let the prime rib rest 25–35 minutes to allow juices to redistribute. Slice thick, against the grain.
  8. Serve & Enjoy: Drizzle with remaining Cajun honey butter or au jus.
