  • 6 lb rib roast
  • 3 tbsp olive oil
  • 4 cloves garlic minced
  • 2 tbsp kosher salt
  • 1 tbsp black pepper
  • 1 tbsp fresh thyme
  • 1 tbsp fresh rosemary chopped
  • 1 tsp sugar
  • 1/2 tsp ground allspice
  • 1/4 tsp cayenne pepper


  1. 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.

  2. Heat the grill to 250F degrees with indirect heat.

  3. Place the roast on the grill, fat side up. Cook until the internal temperature of the meat reaches 110F degrees, about 2 hours.

  4. 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.

  5. 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.
