Ingredients Equipment Method Notes

Ingredients
  

  • 1 Prime rib roast (with or without bone) Any size
Seasoning
  • Garlic powder
  • Salt
  • Pepper

Equipment

  • Roasting pan with rack
  • Meat thermometer

Method
 

  1. Remove the prime rib from the refrigerator at least 2 hours before cooking to allow it to come closer to room temperature.
  2. Preheat your oven to 450 degrees Fahrenheit (232 degrees Celsius).
  3. Rub the entire surface of the roast generously with garlic powder, salt, and pepper.
  4. Place the roast, fat side up, on the rack in the roasting pan.
  5. Place the roast in the preheated oven and cook at 450 degrees Fahrenheit for 15 minutes.
  6. Reduce the oven temperature to 325 degrees Fahrenheit (163 degrees Celsius). Do not open the oven door.
  7. Continue roasting at 325 degrees Fahrenheit. Calculate the remaining cooking time based on your desired internal temperature. A general guideline is 12 to 15 minutes per pound for rare.
  8. Insert a meat thermometer into the thickest part of the roast, avoiding bone.
  9. Remove the roast from the oven when it reaches 120 degrees Fahrenheit for rare, 130 degrees Fahrenheit for medium-rare, or 140 degrees Fahrenheit for medium.
  10. Transfer the roast to a cutting board and tent loosely with foil. Let it rest for 15 to 20 minutes before slicing. The internal temperature will rise during resting.
  11. Slice against the grain and serve.

Notes

The final internal temperature after resting will be about 5 degrees higher than the temperature when you remove it from the oven. Use this guide to achieve your preferred doneness.
