What is Prime Rib Roast?

Prime rib roast or standing rib roast is a gorgeous cut of meat that makes an appearance as the centerpiece of many tables during the holiday season. Prime rib roast is referred to as a standing rib roast because the rib is placed on its rib while it is cooking. A full rack of prime rib has 7 ribs that can serve 12 -14 individuals. The full rack may not fit in your oven, so it’s best to cut the roast in half and cook them in separate ovens or at different times if you only have one oven. Cooked properly, prime rib roast is juicy and flavourful.

How Long Should Prime Rib Be Cooked?

The key to deciphering cooking times depends on the size of your roast. A 5-pound roast usually takes about an hour and a half to cook. Ideally, you should add 20 minutes for every pound of meat. Remember the roast continues to cook after you remove it from the oven. Based on your desired doneness use these temperatures as a guide to testing whether your meat has completed cooking:

  • Medium rare -110 ℉
  • Medium: 120 ℉
  • Medium-Well-130 ℉
  • Well done 140 ℉

Generally, the perfect temperature of prime rib roast is medium-rare. A medium-rare has a red colour with a warm center. Remove the roast from the oven when it reaches an internal temperature of 110℉. Let the prime rib roast rest for 5 minutes before carving.

How To Cook a Prime Rib Roast?

To cook prime rib in the oven, it must be cooked using two different temperatures. First, preheat your oven to 450 ℉, then when the oven reaches the temperature, slide in the roast. Cooking the roast at a high temperature seals in the juices and allows a beautiful golden color form on the outside. Once the searing process is completed, reduce the temperature to 350 ℉ and allow the roast to continue cooking until it reaches a medium-rare temperature.


Prime rib is a high-quality cut of beef. Most premium cuts of beef do not require more than a generous sprinkling of salt and pepper. Prime rib only needs a little salt and pepper as some seasonings may overpower the flavour of the meat.

Rest the Prime Rib Roast

As with any meat, you should let the standing rib roast rest before cutting into it. Pulling the beautiful rib roast out of the oven you may be tempted to reach for a knife and slice the meat right away. But trust me, you do not cut the meat after you just pulled it out of the oven. If you do the juices that were sealed in during the searing process will be lost. In addition to this, you will be interrupting the carry-over cooking process. Transfer the meat to a cutting board and let it rest for 20 minutes.
