Once you learn the best way to reheat prime rib without losing the flavorful juices and pink texture of the meat, you’ll surely find yourself reheating the meat over and over again. The fatty marbled cut of beef known as the standing rib roast is just so hard to resist!


The prime rib roast is a popular dish served in the trendiest restaurants in the world. Of course, you can also prepare the dish right from the comfort of your own kitchen at home. But there are times when we end up preparing more than what we can consume, which is why we have to deal with leftovers. This is why it’s important that you know the proper way to reheat prime rib so if you end up with some leftover in your fridge, you’ll know how to make the dish taste good again.

Best Way to Reheat Prime Rib


You can’t reheat the prime rib and not lose a bit of the meat’s rosy red texture that most diners crave. However, you can come close to imitating the original meat taste if you just know the right way to do it and if you’re patient enough to go through the rigorous process of reheating.

The best way to achieve the medium rare finish when reheating is by reserving the thickest portion of the roast.

Place any leftover in the pan and cover it with aluminum foil. In order to retain the meat’s succulent and juicy quality, add a little bit amount of au jus or a ¼ cup of beef stock.

Reheating Prime Rib in Oven


You need to use the same method of steaming when reheating slices of prime ribs in the oven.

Thing You Need:

  • Oven
  • Baking pan
  • Some broth or water
  • Aluminum foil


  1. First, preheat the oven to 250°F and arrange some slices of prime ribs into the baking pan.
  2. Add a few spoons of broth, although water works well too. However, this could potentially dilute the meat’s flavor a bit.
  3. Tightly wrap the pan with aluminum foil and warm the meat inside the oven.
  4. Transfer the beef in a serving dish and serve.

How to Reheat Ribs in Microwave

Perhaps, using the microwave is the fastest if not the proper way to reheat prime rib. However, the microwave has the tendency to zap all the juiciness and the redness of the meat in a flash so this method should only be used if you’re in a hurry. For this method, start by

Thing You Need:

  • Microwave
  • Kitchen knife
  • Container microwave safe
  • Some broth


  1. Arranging slices of the prime rib meats in a bowl that’s microwave safe.
  2. Cover with a lid and add some broth.
  3. Microwave the meat on high until it’s already warmed through. This should take up to two minutes.
  4. Transfer the prime rib in a serving dish.

Reheat Prime Rib in Steamer

One way to warm up a prime rib is to provide it with a quick steam session. For this method, simply use a steamer basket. You can also use a plate with tin foil or aluminum foil.

Thing You Need:

  • Food steamer
  • Some water
  • Kitchen knife
  • Aluminum foil


  1. Place it in a pot and put water right at the bottom.
  2. Let the liquid simmer in order to steam the meat.
  3. Wrap the slices of prime rib meat with a flat foil pouch and place inside a steamer basket.
  4. Cover the pot and let the meat steam for up to 6 minutes. To determine if the meat is ready, open the foil pouch carefully and try to touch the meat and see if it has already warmed through. If not, wrap the packet again and cover the pot so you can let it steam again for a few minutes more.
  5. Transfer the prime rib in a serving dish.

Reheat Prime Rib Sous Vide


This is a cooking method used by professional chefs to reheat the meat. This method makes use of a vacuum pouch and then heating the prime rib. Such a method can also work well for cooking pre-sliced ribs.

Sous vide is considered as the most beneficial way to reheat prime rib since it lets you control the meat’s temperature, which guarantees that you’ll not end up overcooking the leftovers.

  • Sous Vide cooker
  • Container or pot
  • Vacumm-sealed bag
  • Kitchen knife


  1. Simply place sliced pieces of prime ribs in a pouch that’s vacuum-sealed.
  2. If you want to achieve medium rare texture, set the temperature to 140º F. But for well done and medium, bring the temperature to 165°F.
  3. Place the pouch in warm water and leave it for up to an hour.

Store Leftover Prime Rib is A Must

It’s important that you store any of your prime rib leftovers properly. Wrap it tightly with a plastic wrap and place in the fridge. To achieve the best results, keep the leftover intact instead of slicing it. If there are any au jus left, drizzle it over the meat before wrapping.
