One of the most beloved and iconic restaurants, Subway sandwiches have remained a staple in the American diet since 1965. From its beginnings as a humble sandwich shop in Connecticut, they’ve become so renowned that they’ve been featured in blockbuster films and even mentioned on your favorite TV shows.

But what if you have a leftover Subway sandwich that needs to be reheated? You want it to taste just as fresh and delicious as when you first bought it, but you’re not sure what the best way to do it is.

Fortunately, there are several methods that will work for reheating your Subway sandwich. In this blog post, I’ll discuss the best way to reheat a Subway sandwich in the microwave.

Can I Reheat a Subway Sandwich in The Microwave?

Yes, you can. There are both pros and cons to using the microwave to reheat your Subway sandwich. The biggest pro is convenience – it’s fast and easy to do! Plus, microwaves are very efficient at heating food evenly without burning it.

However, there are some downsides as well. One of the biggest cons is that you won’t get that crispy outside texture you get from the oven or toaster oven. Additionally, the cold cuts, cheese, and vegetables in a Subway sandwich may get soggy during the reheating process.

But if you’re short on time and don’t mind sacrificing some texture, then the microwave may be your best bet.

How Long Should I Reheat a Subway Sandwich in the Microwave?

The amount of time that you reheat your Subway sandwich in the microwave will depend on the wattage of your microwave, as well as the size and thickness of the sandwich.

For a standard-sized, 6” sandwich, you can expect to reheat it for about 60 seconds to 90 seconds. For this post, I use a 1000-watt microwave. If you’re using a higher-wattage microwave, you may need less time, and if you’re reheating a larger sandwich, you may need more time.

How to Reheat a Subway Sandwich in a Microwave: Step-by-Step

  1. Take your Subway sandwich out of the wrapper.
  2. Remove the cold ingredients, such as lettuce, tomatoes, and cucumber and scrape off any condiments such as mayonnaise and mustard.
  3. Wrap the sandwich in a paper towel.
  4. Put the wrapped sandwich into the microwave and heat it for 60 seconds.
  5. Check the sandwich to make sure it’s heated through. If not, add another 30 seconds and check again.
  6. Remove the paper towel, add the cold ingredients back on, and enjoy.

You can reheat your Subway sandwich without a paper towel, but it is recommended to use one. Using a paper towel when reheating a Subway sandwich in the microwave can be beneficial for several reasons.

First and foremost, it prevents the bread from becoming too soggy when it’s reheated. The paper towel also helps to absorb some of the moisture from the melting ice if you reheat your sandwich from frozen.

But if you don’t have a paper towel, you can still reheat your Subway sandwich in the microwave by putting it on a microwave-safe plate.

Safety Tips for Reheating a Subway Sandwich In The Microwave

When it comes to reheating foods in a microwave oven, safety should always be a top priority! Here are some important safety tips that you should always keep in mind before using your microwave:

  • Always use a microwave-safe container when reheating foods like sandwiches – avoid using aluminum foil which can be dangerous when heated up too much.
  • Keep an eye on the food while it’s reheating and stop the microwave as soon as it’s done. Avoid reheating it for too long as that can cause the sandwich bread to become dry and hard.
  • If you’re worried about safety, you can use food thermometers and make sure the internal temperature of your sandwich is 165°F before eating.
  • Let cool slightly before removing from the microwave. This will help finalize the heating process and allow the sandwich to cool down enough before you eat it.
  • Finally, make sure all ingredients are still safe to eat after reheating. This is especially important with items like mayo that can spoil easily if not stored properly.

Why You Should Not Microwave Sub Wrappers?

While it may seem like an easy solution for heating up leftover Subs from previous days’ meals -microwaving sub wrappers is not recommended due to the potential risks involved, including fire hazards caused by paper catching fire inside the microwave and risk of contamination due to possible chemicals leaching into food while being heated inside the wrapper itself. Additionally, microwaving a Subway sandwich in its wrapper can lead to uneven heating of the sandwich.

So if you’re looking to reheat a Subway sandwich in the microwave, it’s best to take it out of the wrapper first and then transfer it to a microwave-safe container or wrap it in a paper towel. This will ensure that the sandwich is heated evenly and safely.

Other Ways to Reheat Your Subway Sandwich

While the microwave is a convenient and fast way to reheat your Subway sandwich, there are other options as well. If you have a bit more time and want a crispier texture, you can reheat your Subway sandwich in the oven. To do this, preheat the oven to 350°F and place the sandwich on a sheet pan. Bake for 8-10 minutes or until the sandwich is heated through.

Alternatively, you can reheat your Subway sandwich in the toaster oven, which will give the same crispy texture as the oven method. Simply set the toaster oven to 350°F and place the sandwich on a baking sheet. Cover the sandwich with aluminum foil and heat one side for five minutes, then flip it over and heat the other side for another five minutes.

Aside from these two methods, people have also successfully reheated their Subway sandwiches with a stovetop and air fryer. No matter which method you choose, just make sure to watch the sandwich carefully as it heats up to avoid burning it.

How to Store a Subway Sandwich for Later

The key to preserving the freshness and flavor of a Subway sandwich is to ensure it is tightly wrapped and stored in an airtight container in the refrigerator. Stored this way, a Subway sandwich can keep fresh for up to two days in the refrigerator.

First, wrap your Subway sandwich in a paper towel. This will help absorb any excess moisture while keeping the bread soft and fluffy. Be sure the paper towel completely envelops the entire sandwich, so no air escapes or penetrates the wrap.

Next, place your wrapped Subway sandwich into an airtight container or baggie. Sealing off all external air from coming into contact with your food ensures that no bacteria grow on it while inside the refrigerator.

Finally, store your wrapped Subway sandwich in an area of the refrigerator where there’s less chance of other foods spilling onto it or coming into contact with it. Make sure that containers containing liquids aren’t placed above or near your designated Subway storage area so that condensation doesn’t drip down onto it and compromise its freshness.


Reheating a Subway sandwich in the microwave is a convenient way to enjoy a tasty and delicious meal with ease. The steps are simple and straightforward, taking only a few minutes of your time. Moreover, it’s important to keep safety in mind when reheating food; make sure your hands and surfaces are clean before handling any Subway sandwiches or wrappers.

Subway sandwiches can also be reheated on the stovetop or in the oven, as well as stored for later if you prefer. Whichever method you choose, remember to wrap and store your sandwich properly to preserve its flavor and freshness for as long as possible.

I hope this guide has provided you with helpful information about how to reheat your Subway sandwich safely and efficiently so that you can make the most out of every meal. So go ahead, grab that cold sub and get ready to enjoy it all over again!
