Can I Reheat Roast Beef? Tips on Which Method Is Best

Roast beef is such a difficult meal to get just right. It needs to be tender and ready to slice, which requires a long, slow cooking.

But it can’t be so overcooked that the meat gets dry and tough. For this reason, when you get it just right, you then have to worry that your leftovers will dry out.

After all, you got it just right the first time. What are the chances it goes right twice?

Actually, the chances are good! As long as you use the right approach with the right appliance.

Yes, of course you can reheat roast beef. Typically, when roast beef is cooked, it does come in a little pink. That way, when you reheat it, as long as you time it perfectly, you can get it perfect again.

The truth is you can reheat any food that has been refrigerated or frozen. All you have to do is be strategic about it.

For example, foods that have been breaded or fried are often best reheated in the air fryer or in the oven. Foods that have been grilled or baked, in contrast, are often best reheated back on the grill or back in the oven.

With roast beef, we are likely going to be best off reheating it in the oven, but let’s run through each appliance to cover all our bases.

How to Reheat Roast Beef in the Oven

Reheating roast beef in the oven is a delicious way to get this amazing meal back on your plate.

  1. Preheat the oven to 250 degrees Fahrenheit.
  2. Place the roast on a wire rack sitting inside of a baking dish or sheet.
  3. Heat the roast for about an hour to one and a half hours and check the internal temperature.

How to Reheat Roast Beef in the Microwave

The microwave is not the best place to try to get meat reheated because it can make the meat tough and chewy.

But, it does not have to be that way.

The best thing you can do is slice the roast beef into thin slices, so you don’t overheat it.

  1. Place your roast beef slices in a microwave safe baking dish and pour some broth over the top. This approach will help keep the roast moist.
  2. Cover the roast with a microwave-safe lid.
  3. Heat the beef for one minute at a time, checking after each time to be sure it heats through.

How to Reheat Roast Beef in an Air Fryer

Reheating roast beef in the air fryer is easy but be warned that it will transform the state of your meal.

It will get your beef heated through, but it will also create a crispy outer crust. This is not necessarily a bad thing.

  1. Slice your roast beef into thin slices and place those slices into the air fryer.
  2. Heat the roast beef slices at 375 degrees Fahrenheit for 3-5 minutes.
  3. Serve and enjoy!

How to Reheat Roast Beef on a Grill

While I don’t usually recommend heating up the grill to get leftovers back in top shape, roast beef is one area where the grill will be helpful.

Especially as a whole roast, you can get a low, slow grill to reheat your roast beef beautifully.

  1. Preheat your grill to 225 degrees Fahrenheit.
  2. Place the whole roast beef on aluminum foil and wrap the roast entirely, so it’s enveloped. Then, wrap it again in another layer of aluminum foil.
  3. Heat the roast directly on the grill over indirect heat for 45 minutes to an hour. Check the internal temperature, and if necessary, heat for another 20-30 minutes.
  4. Serve with your favorite sides and enjoy!

How to Reheat Roast Beef in a Toaster Oven

The toaster oven is a great appliance for heating or reheating, but it’s small, so you have to adjust your food to fit.

  1. Slice the roast beef into individual slices then place those slices spaced out, so they’re not touching on a baking sheet.
  2. Preheat the toaster oven to 250 degrees Fahrenheit.
  3. Sprinkle beef broth over the top of the slices to keep them moist.
  4. Heat the slices for about 15 minutes.
  5. Check the internal temperature, serve with your favorite sides, and enjoy!

How to Reheat Roast Beef in a Pan on the Stove

Reheating roast beef in a pan on the stove is a wonderful way to make French dips sandwiches!

  1. Place a cast iron skillet over medium heat on the stove.
  2. Pour some olive oil into the bottom of the pan.
  3. Slice the roast beef into super thin slices.
  4. Place those slices into the pan and stir them around until the meat is heated through and has a bit of a crispy crust.
  5. Place your roast beef slices on French bread rolls, serve with your favorite sides and dip the sandwiches into some warm au jus.
  6. Enjoy!
