Prime Rib is a special cut of meat that is the highlight of many holiday meals. Prepared properly, you will be asked to make this year after year, so be prepared😉. For another mouth-watering beef recipe, try my Pepper Crusted Beef Tenderloin.

Bite of Prime Rib

Prime Rib

Prime Rib, also known as Standing Rib Roast, is a tender cut of meat that is very flavorful and often served during the holidays. It is more expensive than other cuts of meat, so that is why it is sometimes saved for a special day of the year. You can get prime rib bone-in or boneless. I ended up using a boneless cut of meat for this recipe.

Prime Rib Recipe

With prime rib costing a little more, you want to make sure it is cooked just right! When you ask for prime rib at the store, it is actually a rib roast. If you are getting bone-in rib roast, ask the butcher to cut the bones off and tie them back on. In my case, the bones were already out, so I did not have the option to have them tied on.

Butter Crusted Prime Rib

How to Make Prime Rib

There are plenty of experts out there letting you know exactly what to do (and what not to do) when cooking prime rib. I think people get picky because it is an expensive cut of meat, and usually it is being served to a lot of guests! This recipe is not very complicated and you will also have a gravy to go with the prime rib once it’s cooked.

  1. First, salt your cut of meat and let it sit for at least 30 minutes before cooking. Preheat the oven to 500°F at this time. ALWAYS let your prime rib come to room temperature before you start cooking it. This will allow the meat to cook the most evenly throughout.
  2. In a medium bowl, mix together the butter, garlic, rosemary, thyme, and pepper. Spread this evenly over the ribeye roast.
  3. Bake the roast for 25 minutes. Then, turn off the oven, leaving the ribeye roast in the oven (don’t open the oven door). Cook for another 2 hours, but start to check the internal temperature of the meat after about an hour to get as close to your desired temperature as you can. I have listed a guide to follow to help you determine how ‘done’ you want your prime rib.

Prime Rib Internal Temperatures

Always trust your meat thermometer when checking if your prime rib is cooked to your liking. Since you are not opening the oven door, be sure to use a meat thermometer that has an external wire probe that allows you to see the temperature of the meat throughout the cooking process. These numbers I am giving you are just a guide…you should be checking the temperature regularly so the prime rib won’t be overcooked.

Rare = 120°F to 125°F (bright red center)

Medium Rare = 130°F to 135°F (very pink center, but starting to brown towards the outer edge)

Medium = 140°F to 145°F (pink center with a brown edge)

Medium Well = 150°F to 155°F (no pink)

Well Done = 160°F and higher

PRO TIP: After you take the prime rib out of the oven (once it’s at your desired doneness), cover it loosely with aluminum foil for about 15-20 minutes before cutting into it. This will keep the juices in, but remember that the internal temperature will go up about 5 degrees while it is resting. In addition, begin checking the temperature of the meat about 1 hour into cooking.

How Much Prime Rib will I Need?

Generally, you should estimate about one pound of prime rib per person, especially if you are not serving any other main course. I set this recipe as 1/2 pound of prime rib per person. That is plenty if it is part of a large meal with lots of sides and other goodies. Serve it with Skins on Mashed Potatoes and Roasted Carrots.

Prime Rib and Gravy Being Poured

How to Make the Gravy

After you have transferred the Prime Rib to a cutting board (waiting about 15 minutes before cutting into it), make the gravy using the pan drippings. In a medium saucepan, heat the drippings over medium heat. Whisk in the flour and beef stock, continuously whisking until it thickens up. Slice the prime rib and have the gravy available to pour over the meat. Pair the Prime Rib with Roasted Parmesan Green Beans and Burgundy mushrooms for an impressive presentation!

How to Cut Prime Rib Roast

If the bones have already been removed, as in this recipe, it’s pretty simple to slice prime rib. It is up to you if you decide to trim the fat. I don’t bother with that since some people actually prefer eating the fat. If your guests don’t want the fat, they can easily cut it off their piece. Anyway, when slicing the roast, try not to ‘saw’ through the meat. Just a few clean slices should do it, and you will have beautiful slices of prime rib to serve! Oh, and don’t cut all the pieces at once. Leaving part of the roast intact will keep it warm longer.

Prime Rib is a special cut of meat that is the highlight of many holiday meals!

Ingredients

  • 2 tablespoons salt
  • 5 pounds boneless ribeye roast, trimmed
  • 1 cup butter, softened
  • 7 cloves garlic, minced
  • 2 tablespoons fresh rosemary, finely chopped
  • 2 tablespoons fresh thyme, finely chopped
  • 1 tablespoon pepper
  • 2 tablespoons flour
  • 2 cups beef stock

Instructions

  • Coat the prime rib with salt, and let it rest for 30 minutes.
  • Preheat the oven to 500°F.
  • In a medium bowl, mix together the butter, garlic, rosemary, thyme, and pepper.
  • Spread the butter mixture evenly over the ribeye roast.
  • Bake for 25 minutes.
  • Turn off the oven heat, but leave the ribeye roast in the oven for 2 hours. Be sure to leave the oven door shut so that no heat can escape. I recommend beginning to check the internal temperature after about an hour.
  • Remove the roast from the oven. Transfer it to a carving board, covering it loosely with aluminum foil for about 20 minutes before cutting into it, and pour the pan drippings into a medium saucepan to make the gravy.
  • Heat the drippings over medium heat. Whisk in the flour and beef stock until thickened.
  • Remove from the heat and strain out any clumps.
  • Slice the prime rib and serve with gravy.

    I used the closed oven method. Cook 5 minutes per pound at 500 • degrees then turn the oven off and keep door closed. Electric oven. I inserted a digital probe and removed from oven at 125• meat temperature
    Came out perfect after resting.

  2. I want to try this recipe as a romantic dinner, so will it make any difference if I leave the garlic off since it tends to give gas and bad breath. If it is serving as a tenderizer on this roast can’t I just use meat tenderizer instead? All opinions are welcomed.

    Thanking in advance.

    The math is 5 minutes per pound at 500. Then 2hrs with door closed.

    Do not open. It will be perfect medium rare. No need to check temp. Stick to the formula. It’s foolproof. Done it many times at various weights.
    Always works, even with a little 3lb roast beef.

    I love this method! 5 minutes a pound at high heat then the shut down makes for the most awesome herb encrusted prime rib. I’ve cooked several with this method and with great success.

  5. I used this recipe last year for Christmas dinner. Cooking at 500° with all the butter smoked up my house so badly we had to open doors and windows! Never doing that again.

  6. I’ve made this with slightly different cooking method. It turns out perfectly every time! The hour at 200* might help ease the minds of people who don’t trust turning the oven off completely for 2 hours!

    Keep meat at room temp for 6 hrs.
    Preheat oven to 500*
    Once meat is in the oven DO NOT OPEN OVEN

    1 stick unsalted butter room temp
    1 Tbl. ground pepper
    1/4 tsp thyme
    1/4 tsp rosemary
    1/4 tsp basil
    1 tsp minced garlic

    Blend all together

    Frost top and sides of rib with herb/butter mix the sprinkle with kosher salt – use twice as much as you think you should

    Cook prime rib in glass ware – 500* 5 times the exact weight (for instance 6 lbs. x 5 = 30 min. = 1 min for opening oven)
    Reduce heat to 200* for 1 hour
    Shut oven off for 1 hour.

    This is for med rare
    NEVER, EVER OPEN OVEN TILL DONE

  7. Between all the salt and the beef stock, the gravy turned out way too salty. I would definitely ease up on the salt next time. Plus having a brand new oven, I opted for one of the comments that lowered the temperature to 325* instead of turning it off completely. It was still a little on the rare side, even though the inner temp said 140*. I ended up popping the meat in the oven a few more minutes after slicing, just to bring it up a few more degrees. Overall, very good!

    Followed the recipe to the T. Worked out perfectly. 6.5 lb bone in roast. At the 2 hour mark it finally hit 225. I inserted a probe prior to placing the roast in the oven, yes it is a newer gas oven, only a year old. Definitely going to be a hit.

  9. Try the Reverse Sear Method – there are many great instructions online. Basically roast at 250 until 5 degrees less than desired result, let rest for at least 30 minutes up to 2 hours, THEN roast at 500 for about 5 minutes to crust the outside. I have cooked several prime ribs and this is the best method for me.

  10. What if you want to cook baked potatoes alongside the roast? This method will not allow the potatoes to cook completely.

    I have Been using this method for years. Leave the roast out to get to room temperature takes a couple of hours very important! NEVER. salt meatas it drawes moisture out of it. Coom theroast uncovered 5 minuets to the pound(round up). At 500 degrees and DO NOT OPEN THE OVEN For 2 hours. Use a probe thermometer with a digital out of the oven reader …. no need to rest the roast as it’s been resting for 2 hours
    If you really want delicious prime rib I reccomed dry aging it In your refrigerator for 5-7 days Google for instructions very easy!

  12. i tried using this method but the butter belted off the roast during the 500 degree time. Lots of smoke came tiring out of the oven and my smoke alarms went crazy. The butter was dripping into the pan than goodness. I just waited for the smoke to stop and roasted at 325.

  13. Thank you for this recipe. Prime Rib is not my favorite because of fat and red. But now, with this recipe and lots of great tips I will be trying it.
