Your Ultimate Guide on How to Reheat Roast Beef

You have just hosted an intimate dinner party with family last night. You prepared dinner to make sure that everyone will have a filling treat. You served roast beef as one of the main dishes. Unfortunately, you prepared too much and there have been some leftovers.

What should you do with the leftovers? You have to keep it in the fridge and eat it the next day so that it does not have to be wasted. With this, in the rest of this post, we will teach you how to reheat roast beef, allowing you to still enjoy its optimal taste after being kept inside the fridge.

This does not need to be a difficult task, especially if you have the right equipment. If you do this right, you will be able to enjoy the meat hot while making sure that the texture and flavor are retained. On the other hand, if you do not do it properly, you will not ruin your beef!

What You Will Need

The materials that you will need in reheating roast beef will depend on the specific method chosen or the type of beef. Generally speaking, however, here are some of the materials that you should have:

  • Microwave
  • Oven
  • Air fryer
  • Oil
  • Aluminum foil
  • Microwave-safe container

Of course, and perhaps most importantly, you need your roast beef. It can be reheated foiled or in a container, oiled or not, but this will depend on the doneness of the meat and the specific method that will be chosen. We will further discuss this in the next part of this quick guide.

Here’s How You can Do It

These are the simple steps that you should follow when it comes to reheating your roast beef. Remember, this is only a guide. We are not saying that these are the only ones that will work as there are other options that can prove to be promising, but these steps are what we believe will be the best when it comes to how to reheat roast beef.

1. Know how the Meat is Done



One of the first things that you should do is to determine the degree of doneness of your roast beef, which will be a starting point in determining how long it should be reheated or the specific method that will work best in having it reheated.

  • Rare: This means that your roast beef has been cooked at a temperature of 52 degrees Celsius. The meat comes with a cool red center.
  • Medium Rare: This beef was cooked at a temperature of 57 degrees Celsius and has a warm red center.
  • Medium: On the other hand, this roast beef is cooked at 63 degrees Celsius and has a warm pink center.
  • Medium Well: With this roast beef, it is cooked at 66 degrees Celsius, which should result into a slightly pink center.
  • Well Done: You cook this roast beef at a temperature of 71 degrees Celsius. It results in a brown color with little or no shade of pink

It is easier to reheat roast beef that is well-done, basically because it is less delicate. Rarer beef, on the other hand, needs more careful handling so that you can be sure that you will reheat it without affecting its internal properties.

2. Reheat your Rare Roast Beef

This is the most delicate kind of roast beef. This will be a bit of a challenge since if you do this wrong, this can affect the doneness of the meat, and consequently, its taste and overall quality. The following are the simple steps that you need to follow:

  • Have it taken out of the fridge. Wrap the meat in a foil as a preparation for the heating. You should not heat it directly in order to avoid burning.
  • Place the meat, now wrapped in a foil, inside a microwave-safe or metal bow.
  • In a pot, fill half with water and boil it. Once it has reached boiling temperature, turn off the source of heat.
  • Have the bowl with beef placed inside the pot that contains the hot water. See to it that the bowl will be higher than the level of water, making sure that your foil will not get wet.
  • Place the cover on the top of your pot and let it do its magic. For refrigerated beef, leave it for about 5 to 10 minutes. On the other hand, if the beef is frozen, leave it for at least 20 minutes.

3. Reheat your Medium Rare Beef

If your roast beef is medium rare, you can opt to have it reheated through the same method mentioned above. Otherwise, you can also try the microwave method by following these simple steps:

  • Make sure that the roast beef is unwrapped from the foil. If you are using a microwave, even for other purposes, take note of the fact that reheating any foiled food can damage the appliance. This can lead to short circuits.
  • Use a microwavable plate or bowl instead. When you transfer the roast beef, make sure to include all juices or dripping. This will make sure that it is going to be tasty even after reheating.
  • If the roast beef is frozen, use the microwave’s defrost setting rather than waiting for a long time before the meat thaws. More often than not, ten minutes of defrosting will be more than enough.
  • Reheat the meat using low settings for about four minutes. If it is reheated using high settings and for a longer duration, the tendency is that the meat will dry, losing its flavors and juices.

4. Reheat your Medium Roast Beef

When your meat is done medium, one of the best ways of reheating it is through the use of an oven.

  • Preheat your oven to 350 degrees Fahrenheit. This will ensure the right amount of heat to penetrate inside the beef and to heat it thoroughly.
  • Take out the beef from your fridge. There is no need to wrap it in an aluminum foil. You can expect the results to be the same.
  • Reheat the meat. If it is chilled, 5 minutes of reheating will be enough. On the other hand, if it is frozen, you have to wait for about 8 minutes.

5. Reheat your Medium Well Done Beef

Just like in the case of medium roast beef, you can also use your microwave in reheating your roast beef.

  • Take out the meat from the fridge and have it defrosted or thawed.
  • Preheat the oven at a temperature of 350 degrees. When it is ready, place the beef inside. However, make sure that you wrap the beef first before putting it inside the oven.
  • Reheat the roast beef. Five minutes will be more than enough.

6. Reheat your Well Done Roast Beef

This is the easiest to reheat from all the types of doneness of meat. Since it has been well-cooked, there is no need to worry that juices or moisture can be lost. While you can opt to use the oven or the microwave method following the steps mentioned above, you can also use the air fryer method:

  • Preheat your air fryer at 390 degrees Fahrenheit.
  • Add oil to the air fryer and make sure to evenly spread it on the surface.
  • Place the roast beef on the pan without the aluminum foil, of course.
  • Reheat the beef for at least three minutes or until you can see a heavy amount of smoke coming out of the meat.

Using a pan is a great alternative in reheating roast beef if you do not have microwave or oven. However, it is important to keep in mind that this method will work best only if the meat is well-done. If not, this can result into overcooking the meat and to altering its texture and flavor.


By now, we are hoping that the things shared above made it easier for you to know how to reheat roast beef. Practically, this is one thing that everyone can do. You just need to make that sure to do this on the right way to preserve the flavor and texture of your beef.
