How To Heat Up Leftover Burger And Fries?

If you have some leftover fast food, and you are wondering if you can save them for a later date, we have got good news for you. It is actually really easy to reheat burgers and fries, and there are so many ways that you can do so.

How To Heat Up Leftover Burger And Fries?

Below, we have listed four step-by-step methods of how to reheat leftover burgers and fries.

How To Safely Store Leftover Burger And Fries?

The interval between the period a burger and its accompanying fries are prepared and the time you intend to reheat them is crucial for good storage. By scheduling them properly, they won’t spoil or become unfit for consumption.

Under no circumstances should a burger and fries be left out at room temperature for more than two hours without being appropriately refrigerated. After two hours, they are susceptible to acquiring harmful germs that, when consumed, could cause food poisoning.

You may preserve a burger and fries either in the freezer or the fridge, so they can be reheated later. If you are planning on consuming the burger and fries the next day, or within 3 to 4 days, it will be safe to keep them in the refrigerator.

If you want to keep them fresh and edible for a longer amount of time, it would be best to store them in the freezer. When freezing the burger and fries, you will want to keep them packed inside a sealed container.

Before reheating, allow them to completely thaw, as this will not only maintain the texture, but will also make them easier to cook.

Is It Safe To Reheat Beef?

Although it is not advised to reheat beef more than twice, you can do it once without risk. It can only be warmed once; after that, it must be consumed right away and cannot be done again.

By making sure your beef is securely stored after it has been prepared, you may reheat it safely. It will also be necessary to keep the food at a safe temperature prior to being reheated, and to cook it at a safe temperature while reheating.

The quality of the beef will degrade with each subsequent reheat, so take this into consideration. As a result, once it has been warmed, your beef burger won’t retain the same juicy texture.

Is It Safe To Reheat Chicken?

You can safely reheat chicken as well, so you are free to do so with your leftover chicken burger. To avoid food poisoning, it’s crucial to know how to prepare it safely.

Unlike beef, cooked chicken can be reheated more than once as long as the internal temperature remains at 75 °C/165 °F. But, it is crucial to keep in mind that each time the meat is warmed, the flavor and texture will somewhat deteriorate.

Thus, it would be wise to reheat chicken just the once. To prevent bacteria growth, you must refrigerate your chicken one hour after cooking it, and you should make absolutely sure food is piping hot after cooking before eating.

How To Heat Up A Leftover Burger?

Heating up a leftover burger will vary in effort, depending on how many components are included within the burger. If you just want to heat up the patty, it should be easy enough.

However, you may want to reheat the bun and the fillings too. Below, we have listed four ways to heat up a leftover burger.

Using A Microwave

The fastest and easiest way to reheat a burger is, without doubt, by using a microwave. Like most other foods, it is more than convenient to place a burger on a plate, slide it into the microwave, and wait a couple of seconds for it to heat up.

Unfortunately, while it is obviously the easiest option, the quality of the burger will dramatically decrease after being zapped inside a microwave. It will become dried out, and may even have a new rubbery texture that some will not find appealing.

That being said, this is the quickest way to reheat a burger at home. Here is a step-by-step guide on how to do so yourself:

  1. If the burger contains any fresh fillings, e.g., tomatoes, you will need to remove them. Place them in a separate container for the time being.
  2. If the burger is already wrapped in a paper wrapper, leave it on. If it doesn’t, use some parchment paper to loosely wrap around the burger so that it is covered.
  3. Place the burger on a plate, and place the plate inside the microwave. Set the microwave to 35 seconds on its high power level.
  4. Once the time is up, do not attempt to heat the burger up any further. Doing so will decrease the quality and texture of the food even further.
  5. Remove the burger from the microwave, and allow cooling down for around 2 minutes. It will be piping hot once it has initially been removed from the microwave.
  6. Once the burger has cooled down enough to handle it with your hands, you can begin to reassemble it, placing the fresh fillings back inside. 
  7. You can now serve and consume your reheated burger. 

Using An Oven

According to many, the best method for keeping the quality of a burger is to reheat it in the oven. Due to the amount of burgers you can place within the oven, this technique is also the best choice if you want to warm upwards of two burgers together at the same time.

The oven is strongly advised since it maintains the flavor of your burger and prevents the bread from becoming mushy. It uniformly warms all the ingredients while preserving the texture of each one.

Burger reheating in a regular oven does need some time, but that is its sole downside. Here is how to reheat a burger using an oven:

  1. First, you will need to preheat your oven to 250 °F. You can remove the burger from the refrigerator while you wait for the oven to heat up.
  2. If the burger contains any fresh fillings, e.g., tomatoes, you will need to remove them. Place them in a separate container for the time being.
  3. Grab some aluminum foil, and loosely wrap it around the burger and the bun. Do not wrap it too tightly, as this will affect the quality of the food.
  4. Once the oven has heated up, you can place the burger inside. You will want to leave it to heat up for around five minutes.
  5. After five minutes, remove the burger from the oven. Carefully remove the aluminum foil, and allow cooling down for a few minutes.
  6. Once the burger has cooled down enough to handle it with your hands, you can begin to reassemble it, placing the fresh fillings back inside. 
  7. You can now serve and consume your reheated burger. 

Using A Toaster Oven

You should try utilizing the toaster oven if you want to quickly reheat your hamburger while trying to preserve as much of its quality as you can.

The preheating procedure when employing a toaster oven is a little quicker than when using an oven due to its smaller size, yet the outcome is basically the same.

Only one or two hamburgers can be heated simultaneously using the toaster oven reheating technique; this approach may not prove to be the most effective one to utilize if you would like to reheat more.s

This is the best option if you are merely reheating one or two burgers. Here is how to reheat a burger using a toaster oven:

  1. First, you will need to preheat your oven to 250 °F. You can remove the burger from the refrigerator while you wait for the oven to heat up.
  2. If the burger contains any fresh fillings, e.g., tomatoes, you will need to remove them. Place them in a separate container for the time being.
  3. Grab some aluminum foil, and loosely wrap it around the burger and the bun. Do not wrap it too tightly, as this will affect the quality of the food.
  4. Once the oven has heated up, you can place the burger inside. You will want to leave it to heat up for around five minutes.
  5. After five minutes, remove the burger from the oven. Carefully remove the aluminum foil, and allow cooling down for a few minutes.
  6. Once the burger has cooled down enough to handle it with your hands, you can begin to reassemble it, placing the fresh fillings back inside. 
  7. You can now serve and consume your reheated burger. 

Using An Air Fryer

How To Heat Up Leftover Burger And Fries?

Lastly, we have an option that many people consider to be the greatest method for reheating all foods, including burgers. If you have an air fryer at home, you can use it to heat up leftovers while maintaining its original flavor, texture, and overall quality.

Unlike the other methods, you will need to remove the burger from its bun when reheating in an air fryer. You can always toast the bun by placing it in a toaster oven, or leaving it on a grill for a minute or so.

This method is also only helpful if you want to heat up just one burger at a time, as there is limited space inside an air fryer. Here is how to reheat a burger using an air fryer:

  1. First, you will need to switch the air fryer on, and set it to 350 °F. While waiting for it to heat up, remove the burger from the refrigerator.
  2. Remove the burger patty from the bun, and also remove any fresh ingredients. You only want to reheat the patty itself.
  3. Place the patty within the air fryer, and allow cooking for around 2 to 4 minutes. 
  4. While the burger is heating up, you can take this time to toast your buns if you’d like them to be warm also. You can do this by placing them in the toaster, or cooking them slightly on the grill. Just be very careful not to burn them.
  5. Once the time is up, you can remove the burger patty from the air fryer. Place it on a plate, and allow cooling for a couple of minutes.
  6. When the patty has cooled down, and the buns have been toasted, you can begin to reassemble your burger.
  7. You can now serve and consume your reheated burger. 

How To Heat Up Leftover Fries?

As many of you will already be aware, reheating fries is a lot more difficult than reheating other kinds of food.

While they are easier to store and protect from bacterial contamination, it is difficult to maintain the crispy exteriors and fluffy insides after reheating. Here are four ways to heat up some leftover fries.s

Using An Oven

One of the strongest aspects about warming fries in an oven is without a doubt the ability to cook them alongside the burger. Overall, you’ll save a tonne of time by doing this.

Also, warming fries inside the oven aids in preserving their well-known crunchy exterior and mushy interior.

The oven takes the longest of all the ways discussed, but it is an excellent way to reheat little or big quantities of fries while preserving general effectiveness. Consider switching to an alternative approach if you are pressed for time. Here is how to reheat leftover fries in an oven:

  1. First, you will need to preheat your oven to 250 °F. Remove the fries from the refrigerator as you wait for the oven to heat up.
  2. Grab a baking tray, and cover it with a large sheet of parchment paper or aluminum foil. You will then want to apply some cooking oil across the surface. 
  3. Next, take the fries, and scatter them evenly across the baking tray. Add a little more oil over the top of them, and make sure that each fry is evenly coated with oil. This will ensure that they come out extra crisp.
  4. Once the oven has completely heated up, you can place the baking tray inside. Allow to cook for around 5 to 10 minutes, keeping a close eye on them to make sure they do not burn.
  5. When you notice that the fries have become a golden brown hue, you may remove them from the oven. Allow them to cool for a few minutes before serving.
  6. You can now serve and consume your reheated fries. 

Using A Toaster Oven

The only real difference between reheating fries in the oven and the toaster oven is that the toaster oven requires less time to preheat. In a shorter amount of time, this technique produces the same wonderful, crunchy fries.

It’s vital to keep in mind that while utilizing the toaster oven can save you some time, you won’t be able to warm as many fries as you’d be able to in the oven.

The toaster oven may not be the greatest option if you want to reheat a significant quantity of fries because there won’t be enough room. Here is how to reheat leftover fries in a toaster oven:

  1. First, you will need to preheat your oven to 250 °F. Remove the fries from the refrigerator as you wait for the oven to heat up.
  2. Grab a baking tray small enough to fit in your toast over, and cover it with a large sheet of parchment paper. You will then want to apply some cooking oil across the surface. 
  3. Next, take the fries, and scatter them evenly across the baking tray. Add a little more oil over the top of them, and make sure that each fry is evenly coated with oil. This will ensure that they come out extra crisp.
  4. Once the toaster oven has completely heated up, you can place the baking tray inside. Allow to cook for around 5 to 10 minutes, keeping a close eye on them to make sure they do not burn.
  5. When you notice that the fries have become a golden brown hue, you may remove them from the toaster oven. Allow them to cool for a few minutes before serving.
  6. You can now serve and consume your reheated fries. 

Using An Air Fryer

As we already noted, the air fryer excels at reheating a variety of dishes while preserving their flavor and texture, as well as their overall quality. Fries are no exception, so this is a fantastic method to use to reheat your fries.

This technique only needs a few minutes for completion and maintains that crispness throughout the warming phase. Given its comparatively tiny size, however, the air fryer is probably not the greatest way for reheating a big quantity of fries.

If you want to warm a lot of fries, you might want to use another technique, such as the oven. Here is how to reheat leftover fries in an air fryer:

  1. First, you will want to set the air fryer to 400 °F.
  2. Remove the fries from the refrigerator, and place them all inside the air fryer basket. Then, place inside the air fryer, and begin the reheating process.
  3. Allow the fries to cook for around 2 minutes before removing the basket and giving it a shake. Moving the fries will ensure even cooking throughout.
  4. Place the fries back in the air fryer, and allow cooking for a further 3 minutes.
  5. Once the time has passed, you may remove the fries from the air fryer. Place them on a plate, and allow cooling for a couple of minutes.
  6. You can now serve and consume your reheated fries. 

Final Thoughts

As long as you have an oven, toaster oven, air fryer, or a microwave at home, you will be able to reheat your leftover fast food. We personally recommend using an oven or an air fryer, as these methods provide the greatest results.

If you are in a rush, however, a microwave is always helpful, even if the quality will not be as tasty once it has been heated. We hope you found this guide helpful.
