What You Need to Know About Reheating Prime Rib?

One of the most tender cuts of meat you can get is prime rib.

It’s known for its juicy flavor, but warming up prime rib roast can be a hassle.

If you don’t reheat the prime rib roast properly, it can dry it out making it dull and flavorless.

We highly recommend slicing it before reheating.

You have the option of reheating it in the oven, the microwave, steaming it, or you could simply enjoy it cold.

You can also slice it up and fix it in another meal, so it reheats with the rest of the ingredients.

Find out what works best for you and enjoy a second helping of juicy prime rib.

Pro Tip >> Even if your meat was originally cooked to a lower doneness, when you reheat meat, it should have an internal temperature of 160 degrees Fahenheit. That can be tested with a meat thermometer.

Supplies You’ll Need To Reheat Cooked Prime Rib?

The supplies you’ll need to reheat your cooked prime rib will vary slightly depending on the method of reheating you use.

Here are 4 ways to reheat prime rib:

For steaming, you’ll need:

  • Steamer basket
  • Pot
  • Foil
  • Water

If you’re using the microwave, you’re going to need:

  • A microwave-safe bowl that has a lid
  • Plastic wrap (if you don’t have a bowl with a lid)
  • Au jus/beef stock or water

The oven route requires:

  • A baking pan
  • Foil
  • Beef broth, au jus, or water

How to Reheat Prime Rib Without Drying It Out? (3 Quick Methods)

  1. In The Steamer
  2. In The Microwave
  3. In The Oven
  4. Eat It Cold

Method 1: Reheating Prime Rib In The Steamer

Steaming is a simple, effective way to reheat prime rib and keep it from drying out. This method helps preserve the juiciness of the cut when done properly.

Put a small amount of water in the pot of your choice and bring it to a boil.

Wrap the prime rib in a foil pouch before placing it into the steamer basket.

Steam the prime rib anywhere from 3 to 6 minutes. You can check to see if it’s warmed up by unwrapping the foil and seeing if it’s warmed the entire way through.

If the prime rib is warmed up, move it to a serving plate immediately so it doesn’t cook through anymore.

If it’s not ready to be served, simply wrap it back up in the foil and steam it for another few minutes before checking the temperature again.

Method 2: How to Reheat Prime Rib In The Microwave

Reheating your prime rib in the microwave is not the most ideal way to preserve the flavor and juices of the cut, but in a pinch, it can work.

To reheat the prime rib in a microwave, you’ll want to place the slab of meat in a microwave-safe bowl. Add a few tablespoons of beef stock to the bowl.

You can also use water, but it will dilute the flavor of the prime rib.

Cover the bowl (either with a lid or plastic wrap) and microwave on high for only 1-2 minutes before checking to see if it’s ready.

If it’s not warmed up to your liking, you can simply add more broth as needed and heat it in 30-second intervals.

Microwaves can heat the juice right out of the prime rib in no time, so checking it every 30 seconds after the initial heating can save your prime rib from drying out and losing its flavor.

If it is ready to be eaten, much like with the steaming method, you’ll want to move it to a serving dish as soon as possible to prevent it from cooking further.

Method 3: Reheating Slices of Prime Rib In The Oven

  • Step 1: Preheat oven to 250ºF
  • Step 2: Add the meat to a baking pan and add a bit of beef stock
  • Step 3: Cover the pan with foil
  • Step 4: Check it after 6-10 minutes
  • Step 5: Using a meat thermometer, check for doneness
  • Step 6: Continue in the oven if not at 160 degrees Fahrenheit
  • Step 7: Enjoy…again!

Reheating it in the oven can be tricky since heating it too quickly or at too high of a temperature can quickly dry it out.

A slow and steady reheat in the oven will yield the best results for leftover prime rib.

Preheat your oven to 250 degrees. While the oven is preheating, you can get your prime rib oven ready.

Place your slabs of meat in a baking pan and add a few tablespoons of broth or au jus. You can use water here too, but like the microwave method, this will dilute the flavor a bit.

Cover your prime rib with aluminum foil, ensuring it’s wrapped up tight, and place it in the oven.

Check it after 10 minutes in the oven. If it’s ready to eat, get it onto a serving plate quickly so it does not continue to cook.

If it’s not ready for consumption yet, wrap the prime rib back up in the aluminum foil and give it another 3 minutes before checking again.

Method 4: Eat The Prime Rib Slices Cold

If you’re not feeling up to reheating your prime rib, you can always eat it cold.

Slice the slabs thin and add them to a sandwich or salad.

You can even chop up the prime rib and fix it with another meal. Leftover prime rib makes for great cheesesteaks or stir fry!

How Long Do You Cook a Precooked Prime Rib?

After you prepare your precooked prime rib, you’ll heat it in the oven at 300ºF for about 3 hours depending on the size of it. 

Remember, you don’t want to nuke it. Reheating it low and slow will help keep it juicy. 

How Do You Reheat a Roast Without Drying It Out?

When you reheat your prime roast, you can keep it juicy by warming it up in the oven at 250ºF for 6-10 minutes.

You’ll want to check for doneness to ensure it’s still safe to eat. 

How Long Will Prime Rib Last in the Fridge?

When you’re storing your prime rib in the fridge, wrap it tightly in plastic wrap and it should last around 3 days. 

You’ll want to carefully inspect the meat for any spoilage before eating it, though. 

Can You Freeze Prime Rib Raw?

If you want to save it for a later date, freezing your rib roast is a great idea. 

You can freeze raw prime rib to eat it at a later date. Before freezing the prime rib, you’ll want to ensure it’s still safe to eat. 

Safety Tips When Reheating Meat

When dealing with food, safety is always important. That doesn’t end with reheating food either. 

Here are a few tips to keep in mind:

  • The USDA recommends that reheated leftover meat reach an internal temperature of 160 degrees Fahrenheit 
  • Leftover meat should be examined for spoilage before eating it
