How to Reheat Fast Food

There should really be a technical manual for how to reheat your fast food.  Fast food comes in many presentations, so it is hard to generalize on how to reheat it.  The safest way is to not generalize and break down how to reheat fast food into specific lessons.

Fast food can be reheated many ways depending on what kind of fast food you are talking about.  McDonald’s differs from Taco Bell, which differs from Kentucky Fried Chicken, which differs from Long John Silver’s.  You can reheat all fast food, and the safest method is in the conventional or toaster oven.  The microwave oven is the easiest, but it gives the worst results.

There is nothing worse than delving into the world of fast food without having a plan of attack.  This article is giving me a Big Mac attack, but I am on a diet, so I will just stick to my celery stalks and water. 

How to Reheat McDonalds and Other Fast Food Burgers such as the Mighty Whopper

The best way to reheat your McDonald’s Big Mac, or your Burger King Whopper, or any other fast food burger, is in the oven.  You can use a conventional oven or a toaster oven.  It basically makes no difference, except the conventional oven is larger and will absorb more gas from the burger.

The toppings on the burger complicate matters.  You should remove all fresh vegetables such as lettuce, tomato or onion before reheating the burger.  How would you like to have a piece of wilted slop on your leftover whopper?

Remove the vegetables and put them in the refrigerator.  If the vegetables already look terrible, you can discard them.  We will talk about putting fresh lettuce and tomato on our burgers later.

How to Reheat a Fast Food Burger in the Conventional Oven.

  1. Preheat the oven to 400 degrees.
  2. Remove all vegetable material from your burger.
  3. Find a cookie tray somewhere in your kitchen.  It is probably under some soda pop cans.
  4. Put the burger on the cookie tray face down.  I know this sounds weird, but it creates a better beef flavor when it cooks on the metal.
  5. When the oven preheats, put the burger in the oven.
  6. Reheat for 5 minutes, or until the bread is toasting.
  7. Remove the burger from the oven.

  5. Cook at 420 degrees for 5 minutes.
  6. Remove from the toaster oven.
  7. Add sour cream.

  1. Leave the burrito in the wrapping paper.
  2. Put the burrito on a microwave-safe dish.
  3. Put the burrito in the microwave oven.
  4. Set the timer for 45 seconds.

Remember that you are dealing with a delicate piece of fish. The fish is so tender that it melts in your mouth. The fish is also so tender that it can turn to mush in your oven.  Reheating your Long John Silver’s is not as easy as reheating a Big Mac. 

To Reheat Long John Silver’s Fish in the Conventional Oven

  1.  Preheat the oven to 400 degrees. This seems like a high temperature, but we want to cook the leftover fish fast.
  2. Find a cookie sheet. An aluminum plate will do, or you can even wrap your Long John Silver’s in a piece of aluminum foil.
  3. Remove condiments from any part of the fish. Cut off any parts that have catsup or tartar sauce on them. These parts will not cook and will turn into a mushy substance that resembles wet bread.
  4. Pick off any parts of the fish that are overcooked. These dry pieces of fish will cook to the point of burning.  You don’t want the flavor of burnt fish in your Long John Silver’s leftover fish stick.

  8. The crust should get pretty hard by now. If it isn’t hard, put the fish back in the conventional oven for another 2 minutes.
  9. If the crust is hard, take the fish out of the oven.
  10. Serve immediately.
