How To Reheat Prime Rib Perfectly

Are you having prime rib for dinner? We’re sure the whole family will love your succulent dish. But what are you going to do if you have lots of leftovers? It will be such a waste to just throw it all out. The best thing to do instead is to store your ribs for later. You can either freeze or refrigerate them, depending on how long you think it will be before you eat the ribs again.

With this in mind, it’s vital to understand how to reheat prime rib properly. But before we talk more about the steps on doing that, let’s discuss some tips on how to correctly store your leftover meat. Here are some pointers to keep in mind:

  • Leftover prime rib can last longer in the freezer - up to six months if stored properly.
  • It can last up to a week if refrigerated.
  • When storing, don’t slice the ribs (if they aren’t yet). It’s better to keep them intact or as one whole slab of meat.
  • You can also sprinkle a few tablespoons of au jus, if there’s some left over, on the ribs before wrapping them.
  • The best way to achieve a perfect medium rare after reheating is by earmarking the meat’s thickest part.
  • The secret to a pink, moist and juicy prime rib is patience. Reheating, just like cooking it, takes a lot of time if you want to get it right.
  • Even with all these tips, it can be near impossible to achieve a perfect color and taste equal to a newly roasted or grilled prime rib. Still, reheating can give a satisfying outcome for leftovers.

How to Reheat Prime Rib by Baking

1. Preheat your oven to 300 degrees.

2. For roasted prime rib, place the entire leftover roast in a baking pan.

3. Cover it with foil. If there is any au jus left, add a bit of it to help keep the meat moist and juicy. If there isn’t any left, you can use beef stock instead.

4. Bake for about 20 to 30 minutes (longer if the size is bigger).

5. Check the internal temperature using a meat thermometer. The USDA requirement for reheating is at least 160 degrees.

6. Serve and enjoy!

This isn’t a top recommendation. However, it can be a good solution if you’re in a hurry or if you don’t mind not having perfectly pink and moist meat. You will also sacrifice some of its tenderness.


1. If frozen, be sure to defrost or thaw first. Defrosting in the fridge will take 24 hours. So do this prior to reheating.

2. You can slice the prime rib if you want to do a quicker reheating.

3. Place the ribs in the microwave-safe plate.

4. Heat with 30-second intervals. Check the temperature after each heating to see if you got it right.

5. Try not to overcook it because it can turn hard and chewy.

6. When done, transfer to a dish and serve.

How to Reheat Prime Rib by Steaming

The reheating prime rib can be really tricky. You can overcook it and turn it hard and stale. You can suck out all of its moisture and tenderness. Here’s a good way to increase your odds at getting a near-perfect outcome, almost the same as when you first roasted it. This also works best if you had the ribs in a restaurant and had to take your leftovers home. This method is better than baking or microwaving in terms of retaining all of the ribs’ original juices and flavors.


1. Place the prime ribs on a sheet of foil.

2. If you have au jus, drizzle about three tablespoons over your ribs. Be sure to cover the meat evenly. If you don’t have any, again, the beef broth will do. (If you had it in a restaurant, you can request for some extra in a to-go cup.)

3. Once covered with au jus, wrap the ribs with the foil. Make sure it is properly sealed.

4. Place the ribs in a steamer basket and put over steam on High. Do this for about five minutes. The bigger the meat is, the longer you’ll have to steam it.

5. Once done, simply unwrap and transfer to a dish. Serve and have a feast!

 Eating prime ribs is one of the man’s simple joys. There’s no experience like sharing a meal of high-quality meat with delicious sides and refreshments with family or friends. Whenever you have leftovers, you don’t have to feel bad for wasting such prime meat. You now know that you can always freeze or refrigerate it and reheat it for later. This way, you can enjoy your ribs whenever you feel like it. If you follow these tips and pointers, you can be sure to have a moist, delicious, and perfect serving of prime rib anytime.
