This prime rib recipe is nothing short of fantastic. I am pretty sure that Chef Ted Reader read my mind and knew exactly what my barbecue dreams were made of when he decided to make a recipe that involved one of the best cuts of beef on the planet and smother it with 101 cloves of roasted garlic. Originally put up on the site in 2011, I have made this recipe a few times, much to the delight of others. Then again, who wouldn’t love succulent prime rib, roasted on a plank, encased in a flavorful roasted garlic crust? You may want to enjoy some vermouth-wash instead of after-dinner liqueurs because when you eat this grill recipe, things are about to get intense!

101 Cloves of Garlic Prime Rib

Serves: 4 to 8       Total Time: 1 Hour 30 Minutes


  • 1 large thick oak plank soaked in red wine and water 
  • 1 Marinade Injector
  • 1 bone–in prime rib roast, 4 to 8 lbs.
  • ¼ cup Sweet Spice Rub
  • 101 cloves of Grill–Roasted Garlic
  • 3 tbsp. olive oil 
  • 3 tbsp. honey 
  • 3 tbsp. dijon mustard
  • 2 tbsp. fresh rosemary, chopped (1 tbsp. dried and crushed) 
  • 2 tbsp. prepared horseradish
  • 1 cup Shiraz red wine
  • ½ cup melted butter


Step 1
Preheat the grill to 450°F.
Step 2
Rub the prime rib with the Sweet Spice Rub, pressing it firmly into the meat so that it adheres. Using a fork to mash the garlic, mix together the roasted garlic, oil, honey, mustard, rosemary, and prepared horseradish, set aside.
Step 3
Place your soaked plank on the grill, over direct heat for 5 minutes, until it starts to crackle and smoke. Place your seasoned prime rib roast directly on the plank and roast for 15 minutes at 450°F. Reduce the heat by turning off the burner under the plank, until the grill holds a steady 350°F temperature. This should only take two burners on medium. Spread the roasted garlic mixture evenly over the top of the prime rib, close the lid and allow the prime rib to roast on the plank for another hour or so. Use the Napoleon Wireless Digital BBQ Thermometer to monitor the interior temperature of the beef without having to lift the lid and loose all of that precious heat.
Step 4
When the meat has reaches around 65°F to 75°F inside – about halfway through cooking - combine the red wine and melted butter. Using the Marinade Injector, inject the red wine mixture into the roast in several places.
Step 5
When the prime rib is done – medium rare is 130°F - remove the plank from the grill; loosely cover with foil and let it rest for 15 minutes before carving. Slice the prime rib as thick or thin as your taste prefers, and serve with additional prepared horseradish on the side, and a good glass of wine.

I remember the first time I made 101 Cloves of Garlic Prime Rib. I was relatively new to using a barbecue, and it was my first time using the Napoleon Prestige™ 500. It was a propane model, and I didn’t realize that I had used all of the gas. I ran out of propane right in the middle of the cook! Of course, that was AFTER I lit the plank on fire, and ran out of dijon mustard and butter! Considering everything that went sideways on my first attempt at grilling something so incredible on a BBQ, you must be surprised that I picked up the tongs and tried again. That’s the thing about any sort of cooking, though. You have to keep trying. Keep trying new recipes, keep trying new techniques, and keep trying when you don’t get that recipe right. What is the biggest BBQ disaster you’ve ever dealt with? Did the meal turn out in the end?

Happy Grilling!
