Ingredients

Instructions

  • Take the prime rib out of the fridge 2 hours before cooking.
  • Preheat the oven to 250°F.
  • Dry the roast with paper towels.
  • Rub olive oil and Worcestershire sauce over the roast, then season with salt, ground black pepper, sugar, chili flakes and chopped rosemary leaves, covering all sides.
  • Place the prime rib roast in a roasting pan fitted with a wire rack.
  • Roast at 250°F for 2 hours and 30 minutes, or until the internal temperature reaches 125°F in the thickest part of the meat. Use an Instant Read Meat Thermometer to check for doneness.
  • Remove the prime rib from the oven, cover with foil, and let it rest for 30 minutes.
  • Meanwhile, increase the oven temperature to 500°F.
  • Uncover the prime rib and put it back in the oven.
  • Roast until browned and crisp on the outside, about 5 to 10 minutes.
  • Remove from the oven and let it rest for 1 hour before cutting and serving.

Notes

  • Meat Thermometer: Meat thermometers are always handy but never more essential than when making something as good as prime rib. Without a meat thermometer, you can only guess the doneness of your roast. 
  • Doneness: Roast the prime rib until it’s about 3 to 5 degrees from the ideal temperature, and then take it out of the oven. It will continue to cook on the counter, bringing it up to the last few degrees.
  • Prime Rib Temperatures: 125˚F to 130˚F is the perfect medium-rare, delivering a rosy pink color. If you want, you can cook the roast a bit more, to 140˚F. I wouldn't go beyond 145˚F because the meat can get dry at this point.
