Ingredients
  

  • 5 pounds prime rib roast bone-in
  • 4 teaspoons seasoned salt
  • 2 teaspoons black pepper coarsely ground
  • 1 teaspoon dehydrated minced garlic
  • 1/4 teaspoon thyme dried

Instructions
 

  • In a small bowl, mix together the ingredients of the rub. 
  • 2 to 3 days before roasting, rinse and pat dry the meat. Coat the roast with the dry rub making sure it is well coated on all sides.
  • Wrap the coated roast in plastic wrap and refrigerate overnight (or as long as 3 days).
  • Two hours before cooking time take the roast out of the refrigerator and leave in the plastic wrap and let the meat come to room temperature.
  • Spindle the roast, secure it inside the Showtime Rotisserie, and cook 18 minutes per pound for a medium, 15 minutes per pound for medium-rare, or 12 minutes per pound for rare. See note below.
  • Let the roast rest for 20 minutes on the no heat rotisserie mode, or remove from spindle and tent with foil on a cutting board.
  • Slice and serve with steakhouse sides.

Notes

  • 20 min/lb - 150 - 155 degrees for well
  • 18 min/lb - 140 - 145 degrees for medium
  • 15 min/lb - 130 - 135 degrees for medium rare
  • 12 min/lb - 120 - 125 degrees for rare
**More important than the minutes per pound is the temperature. It’s better to under cook than to overcook. I have over cooked a couple of roasts beyond medium rare, and while that is a big bummer the flavor is still amazing.  Also remember, the meat will continue to cook a bit as you let it rest. I aim for the rare temperature and it comes up another 5 degrees while resting. So, you can start as low as 10 minutes per pound and check the temperature before adding another 2 to 5 minutes per pound for a final temperature between rare and medium rare.
When the temperature is 5 degrees below the final desired temperature. Let the roast rest for at least 20 minutes on the no heat rotisserie mode, or remove from spindle and tent with foil on a cutting board.
