How To Reheat Prime Rib – 4 Easy Way To Reheat Prime Rib

How To Reheat Prime Rib: There’s a reason why it’s called a prime rib. A standing rib roast, also known as prime rib, is one of the most tender cuts of meat. In addition, it pairs well with a variety of side dishes (like Creamed Kale and Gruyere Gratin!).

Regardless of whether you order out or cook for yourself, one serving will never be enough. In contrast to popular leftovers like turkey or ham, prime rib won’t maintain its signature fresh, juicy taste when reheated. That’s because, unlike turkey and ham, the prime rib loses its signature flavour once reheated.

Reheating prime rib the right way doesn’t seem as simple as popping old leftovers in the microwave (which you can still do, but with great care) but you will reap the benefits of a more tender and flavorful meal.

Depending on what you have left, you have several options for how to reheat prime rib properly.

4 Most Popular Ways To Reheat Prime Rib

1. Reheat Prime Rib in the Oven

Using an oven to heat prime rib is key to this delicious day-after meal. Just be careful not to overcook it. It is best to reheat meat in the oven if you want the meat to stay moist. This method is also ideal if you want to reheat a whole prime rib roast.

The trick to cooking prime rib at a low temperature is adding some extra moisture to prevent it from drying out. Most chefs and foodies prefer it this way to ensure the tenderness of the meat at the center. The following 4 steps will show you how to reheat prime rib in the oven:

reheat rib

  • Once you have cooled down your prime rib to just about room temperature, place it in a roasting pan in a baking pan and heat the oven to 300 degrees Fahrenheit. Try not to let the prime rib sit out for too long before roasting it. You are more likely to get a foodborne illness if you do this.
  • Over the au jus meat, place your leftovers. You can also add about 1/4 cup of beef stock. After about an hour, bake your leftovers for about 160 to 165 degrees until the internal temperature has reached.
  • When reheating prime rib, do you need to check the temperature about every 10 minutes? Experts note that cooking times could vary depending on your oven, so to avoid drying the meat out or overcooking, she suggests monitoring it every 10 minutes.
  • The prime rib is now ready for serving! Garnish it with your favourite seasonings, and you’re all set!

2. Reheat Prime Rib In a Steamer

When it comes to gently reheating prime rib, you need to use a steamer (also known as a double boiler). Here’s what you need to do:

Things You Will Need

  • Prime rib
  • Aluminum foil
  • Au jus or beef broth
  • A steamer
  • A thermometer


  • You should fill the bottom of your pot with at least one to three inches of water before placing the steamer basket on top and turning it on the stove.
  • Make a pouch out of aluminum foil by pulling one sheet out and bending the corners. The pouches will be warmer if you simmer the water while making them.
  • Do not seal the foil pouch until you have drizzled some leftover au jus over the prime rib. Place the leftovers in the foil pouch and seal the edges.
  • It should take about 3 to 6 minutes for the prime rib to heat through after being placed in the steamer. Cover the pot and let the food sit for a few minutes.
  • Place a meat thermometer into the meat and check the internal temperature. The temperature should be between 160 and 165 degrees Fahrenheit.
  • The prime rib should also be prepared right away after removing the pouch from the steamer, so you don’t keep it from continuing to cook internally. When serving, drizzle the au jus over the prime rib to stop it from further cooking.

3. Reheat Prime Rib on the Stovetop

To warm leftover prime rib on the stovetop, simply add one to three inches of water to the bottom of the pot, based on the size of your pot. This will eliminate the need to heat the oven. As the pot comes to a simmer, place a steamer basket over it and pour water into it. Place a foil pouch over the upper part of the basket, put the lid on the pot, and steam for about 3-6 minutes.

After 15 minutes, carefully remove the foil and hold the rib over a pot of simmering water for a few seconds to get it warmed through. Once done, remove immediately to a serving platter so it doesn’t continue to cook earlier.

4. Reheat Prime Rib in the Microwave

Even though you should never use the microwave for more than 30 seconds at a time, you might be able to manage it if you’re in a rush.

If you microwave your prime rib when it is still hot, you’ll lose all the tenderness and flavor you labored over for the meat. Put it in a microwave-safe dish with a little remnant juice or broth and cover it before you microwave it.

Slice the prime rib into equal-sized pieces to ensure thorough cooking. The beef should be heated for 30 seconds at a time after cooking for 1 minute.

.. or Enjoy it Cold

Just saying, cold prime rib is not something to be sneered at. It would make a great addition to a sandwich or salad when thinly sliced. Or you can prepare a breakfast hash or a cheesesteak with the leftover meat or toss it into a stir-fry if the cold prime rib is not your thing.


1. How do you warm up a precooked prime rib?

Wrap the leftover roast in foil and place in a pan. Depending on the size of the piece, heat the oven to 300 degrees for approximately 20 to 30 minutes.

2. How do you reheat a roast without drying it out?

Sliced leftover pot roast is baked in a baking dish after it has been reheated. Then I add the drippings from the pan to the meat, along with additional beef broth if necessary. It is then covered and baked at 325° only until heated. The meat is thus kept moist without being overcooked or dried out.

3. Can you reheat medium rare prime rib?

As a general rule, set your sous to vide to a temperature of 140o F for medium-rare prime rib. The prime rib that is rare should be reheated sous vide. The ideal temperature for prime rib is 165o F. Cook your pouch for about one hour low and slow in the warmed water.
