This standing rib roast recipe—more often called prime rib roast—is a showstopper of a main dish that's perfect for holidays and special occasions. Simple seasonings and a varied roasting temperature (it starts high and then is turned down low) complement the exquisite flavor and tenderness of this cut of meat.

Cooking a whole prime rib roast ensures that each of your guests can have a serving that’s done to their liking. The very center of the roast will be rosy pink, pleasing everyone who loves their beef rare, and the nicely browned end cuts will satisfy the people who prefer their meat more done.

What Is Prime Rib?

The name “prime rib” is derived from butcher’s terminology: beef cows are divided into eight primal cuts, one of which is the rib cut. The name is not related to USDA beef grades—a measure of quality and fat marbling. The top grade of beef is Prime. And here it’s worth the splurge to get Prime grade prime rib.

How Much to Prime Rib to Buy

A roast cut from the first three ribs of the prime rib is known as the first cut. A trimmed, bone-in first cut prime rib roast usually weighs between 7 and 9 pounds. Count on buying 1 pound per person for a bone-in prime rib roast.

It’s a good idea to order your roast ahead of time from a butcher to ensure you get the quality and size you want.

To ensure even cooking, the roast must first be left at room temperature for about two hours before being placed in the oven.

  1. Preheat oven and season roast:

    Place oven rack on lower level. Preheat oven to 450°F. Rub salt and pepper all over the roast.

  3. Roast meat, reducing oven temp after 20 mins:

    Cook for 20 minutes. Reduce oven temperature to 325°F, and continue cooking until an instant-read thermometer inserted in the thick end of the roast (not touching a bone) reaches 115°F, about 1 hour and 25 minutes. If it hasn't, return it to the oven; check the temperature at 10-minute intervals.

  4. Allow meat to rest:

    Transfer roast to platter; set aside in a warm spot for juices to collect. (As the roast rests, the temperature will increase by about 10°F.) Do not tent, or the crust will get soggy. The short ribs can be eaten as a snack, or reserved to make flavorful soups.

Testing for Doneness

Prime rib is best served rare. To determine doneness, insert an instant-read thermometer into the thickest part of the meat, ensuring that it does not touch the bone. Remove it from the oven when it reaches 115 to 120 degrees Fahrenheit, and then set it aside to rest in a warm place (such as the back of the stove) for at least 15 minutes before carving.

Frequently Asked Questions

  • Is standing rib roast the same as prime rib?

    Yes, standing rib roast and prime rib roast are the same and the names are interchangeable. In some areas, this cut is known as prime roast or rib roast. Also, remember that the name "prime rib” does not automatically mean that it is Prime grade beef.

  • How far in advance should you buy a prime rib?

    You should buy your prime rib in advance to be sure you can get the meat you need. It’s a good idea to order prime rib from the butcher. Call to find out how far ahead you need to order, but plan to allow at least a week.

  • Do you cook prime rib bone up or down?

    Prime rib should always be roasted bone down. This is so that the layer of fat goes on top will slowly baste the meat as it roasts. The bones also form a natural roasting rack!

  • Do you cook prime rib covered or uncovered?

    Prime rib should be cooked uncovered so the exterior gets browned and crisp. We do not cover the meat even while it is resting after roasting because that will compromise the crispy crust. If the prime rib is browning too quickly in the oven, you might consider covering it with foil but we do not find this is an issue.
