Holiday prime rib! Is there anything more luxurious than a beautifully roasted medium rare prime rib roast for the holidays?

I think this is one of the most amazing main dishes out there. It’s also one of the most intimidating for the home cook given the cost of the roast to start with. No one wants to ruin a prime rib roast and end up feeding an expensive cut of meat to the dog. But it doesn’t have to be scary, it’s actually super simple!

How Long Do I Cook Prime Rib?

Cook time for prime rib depends on the size of the roast. Plan on about 15 to 20 minutes per pound. Keep in mind that the roast will continue cooking once it comes out of the oven. Follow these temperatures for when you’ll want to remove the meat from the oven based on your desired doneness.

  • Medium-rare — 110º
  • Medium — 120º
  • Medium-well — 130º
  • Well — 140º

Once the roast is removed from the oven, it’s important to let it rest for at least 15 minutes before slicing. This ensures the roast will retain all the juices. If you slice it too early, the juices will run out and you’ll be left with a rather dry piece of meat.

Many recipes will instruct you to cover the roast with aluminum foil as it rests. I don’t bother with this step and I’ve never had an issue. I usually end up with an internal temp above 110 degrees by the time I get it out of the oven so I don’t want to insulate the heat. I want it to cool quickly to stop the cooking process.

Serve up this delicious holiday prime rib roast with your choice of veg. Any kind of roasted or mashed vegetable pairs really well. I usually do roasted asparagus, but I have also done Garlic Mashed Cauliflower, Roasted Broccoli, Brussels Sprouts, and Onions, or Sauteed Balsamic Mushrooms.
