Rotisserie Prime Rib

Yes, the Ronco Rotisserie truly DOES make the best Prime Rib! Set it and forget it! OK not really, as you do want to monitor it for doneness, but almost. Shown here with homemade scalloped potatoes.

  • Ronco Rotisserie


  • 1 Prime Rib Either a large 2 bone or small 3 bone roast
  • Garlic Cloves
  • Olive Oil
  • Prime Rib Rub Below

The Rub

  • Kosher Salt
  • Course ground Black Pepper
  • Cajun Seasoning Tony's or Emeril's

Horseradish Sauce

  • 1 cup Sour Cream
  • 1-2 tbsp Horseradish to taste
  • 1 tsp Lemon Juice
  • 1 tsp Worchestershire sauce
  • Salt & Pepper to taste

Au jus

  • 1 quart Beef Broth whole carton
  • 1 tbsp Beef Broth Powder


Prime Rib

  • Peel the garlic cloves and slice long ways to make manageable spears
  • Cut small slits into the roast and insert the garlic spears
  • Gently coat with olive oil and then cover with a generous coating of the rub mixture, ensuring to massage the mixture into the roast (that's why it's caused a rub).
  • Let the roast rest for at least 30 minutes to allow the rub to soak in.
  • Load the roast into the rotisserie, and set the machine to 2 hours.
  • If desired, now is the time to make the Au Jus and Horseradish Sauce.
  • Starting around the 1 hour mark, check the doneness using a meat thermometer in the center of the roast. Remember that the temperature will continue to rise while it rests, so pull it out when the temperature is 10-15 degrees below your desired doneness.
  • Let the roast rest for 15 minutes, then slice into your desired pieces and serve with the Au Jus and Horseradish Sauce (if desired). Add any juices into the Au Jus.

Horseradish Sauce

  • Combine all of the ingredients into a small bowl
  • Cover and let rest in the fridge until the roast is done.

Au Jus

  • Pour the beef broth into a medium sauce pan
  • Stir in the powdered beef broth
  • Set the stove on medium and let the broth reduce by 1/3, while the meat cooks.
  • If desired, thicken with either a water/corn starch mixture or a tsp of Glucomannan (no carb/Keto option) – or nothing (my family prefers it straight)
  • Remove from heat, and add any juices from the meat for extra flavor
