A delicious and convenient way to prepare a prime rib roast is by using your rotisserie unit. This recipe calls for a flavorful herb rub that adds a nice crust to the roast as it cooks. This dish is perfect for the holidays or special occasions.

Ingredients

  • 1 (4 to 5 pound) bone-in rib roast
  • For the Seasoning:
  • 1/3 cup olive oil
  • 4 cloves garlic, minced
  • 1 tablespoon sea or kosher salt
  • 1/2 tablespoon dried oregano
  • 2 teaspoons dried thyme
  • 2 teaspoons onion powder
  • 1 1/2 teaspoons apple cider vinegar
  • 1 1/2 teaspoons freshly ground black pepper
  • 1 teaspoon dried tarragon
  • 1 teaspoon mustard powder
  • 1 teaspoon chili powder

Steps to Make It

  1. Gather the ingredients.

  2. Place prime rib roast onto a large cutting board. Combine seasoning ingredients and spread over roast. Make sure it is well coated.

  3. Prepare grill for rotisserie cooking following the instructions in your grill manual.

  4. Place the rib roast bone-side down. If you are using a boneless rib roast just place it on its side. Lift the roast from the ends and rotate it to find its approximate center.

  5. Using a long, thin blade knife, cut through the center end to end.

  6. Run the rotisserie skewer through the hole and loosely secure with the rotisserie forks.

  7. Place roast on grill and adjust to center; then tighten the forks.

  8. Remove from roast grill in order to preheat grill to a high temperature.

  9. Place an aluminum drip pan under the space where the roast will sit. Add about 1 cup of water to the drip pan, if you intend to make gravy with the rendered juices.

  10. Using heat-resistant gloves, return roast to grill once it has pre-heated.

  11. Leave the grill on high for 20 minutes, then reduce the temperature to medium-low. Continue cooking until the internal temperature reaches at least 120 F (140 F for medium done), about 3 to 4 hours.

  12. Remove from grill and rotisserie rod, cover with aluminum foil, and allow to rest for 15 to 20  minutes.

  13. Carve and place onto a platter.

Kitchen Notes

  • Use one drip pan (a disposable aluminum pan works well).
  • The total cooking time should between 3 to 4 hours, depending on the grill. It is important to monitor the internal temperature, however. Make sure when testing the temperature to stop the rotisserie motor and check in a place near the center of the roast, but away from the rotisserie rod or the bone, both of which will be very hot.
