Ingredients

  • One 5- to 6-pound bone-in standing prime rib roast, trimmed of excess fat
  • 6 large garlic cloves, peeled
  • 1/4 cup lightly packed fresh rosemary leaves
  • 1/4 cup lightly packed fresh basil leaves
  • 2 teaspoons kosher salt
  • 2 teaspoons freshly ground black pepper
  • 3 tablespoons Dijon mustard
  • 3 tablespoons extra-virgin olive oil

Method

  • Allow the roast to stand at room temperature for 30 to 45 minutes.
  • Put the garlic, rosemary, basil, salt, and pepper in a food processor and pulse to finely mince.
  • Add the mustard and olive oil and process to form a paste.
  • Smear the paste all over the top and sides of the roast.
  • Oil the grill racks.
  • Preheat your grill using all burners set on high and with the lid closed for 10 to 12 minutes.
  • When the grill is hot, cut off the center or back burner and adjust the heat to medium.
  • Put the roast on the grill, bone side down, close the lid, and cook to your desired doneness, 1 1/2 to 2 hours for medium-rare (the meat will register 135F to 140F on an instant-read thermometer).
  • Transfer the roast to a cutting board and remove the bones.
  • Loosely cover the roast with foil and let rest for 20 to 30 minutes.
  • The internal temperature will rise 5F to 10F.
  • Carve the meat into slices and serve.
