Grilled Prime Rib Roast

Prime rib roast is probably the most luxurious piece of meat. When it's cooked following our technique, it melts in your mouth with an herbaceous crust.

Ingredients

  • 6 lb rib roast
  • 3 tbsp olive oil
  • 4 cloves garlic minced
  • 2 tbsp brisket or steak rub
  • 1 tbsp fresh thyme
  • 1 tbsp fresh rosemary chopped
  • 1/2 tsp ground allspice

Instructions

  • Combine the oil, garlic and spices in a bowl. Rub all over the meat. Let rest on the counter at room temperature for 2-3 hours.
  • Heat the grill to 250F degrees with indirect heat.
  • Place the roast on the grill, fat side up. Cook until the internal temperature of the meat reaches 110F degrees, about 2 hours.
  • Keep the meat over indirect heat, and raise the grill heat to 400F degrees. Grill until the internal temperature reaches 135F degrees, about 30 minutes. Remove from the grill. Let it rest 30 minutes before slicing.
  • Slice and serve. For those who like their rib roast well done, throw their slice back on the grill until it reaches their preferred doneness.

Notes

My Brisket Rub is currently out of stock. Therefore, I recommend using equal parts kosher salt and coarse-ground black pepper or your favorite steak rub. 
I revised the herb rub for this recipe in July 2021, because some people commented that it was too salty. If you were a fan of the original recipe, it’s below.
  • 3 tbsp olive oil
  • 4 cloves garlic
  • 2 tbsp kosher salt
  • 1 tbsp black pepper
  • 1 tbsp fresh thyme
  • 1 tbsp fresh rosemary
  • 1 tsp sugar
  • 1/2 tsp ground allspice
  • 1/4 tsp cayenne pepper
