Reheat a Subway Sandwich

Is there a proper way to reheat a Subway sandwich?

So you were feeling adventurous and bought a foot-long sandwich from Subway, but now you realize that you can’t finish the whole thing. But it’s not such a bad thing. In theory, a foot-long sandwich could keep you full for a weekend. All you need to know is how to reheat it properly, so you can enjoy it the same way the next day.

So whether you bought a foot-long, or have ended up leftovers from the 6-incher, do not throw it away and learn how you can reheat a Subway sandwich to its optimal taste.

How to Store Leftovers?

It is necessary that you store your leftover sandwich as soon as possible, so it doesn’t start developing bacteria. As a general rule of thumb, any food kept on room temperature for more than 2 hours should be thrown away.

  • Tightly wrap your sub in a plastic wrap or tin foil, or store it in an airtight container
  • Store it in the fridge for up to 2 days
  • If you don’t plan on consuming it within two days, throw it in the freezer. It will stay good for up to three months

This is your best bet when it comes to reheating a Subway sandwich. Since it will reheat everything properly, you will not have to worry about the ingredients inside being left cold. The only drawback is that it will take a little longer than other method, but it is definitely worth the wait.

  • Preheat the oven to 350 degrees Fahrenheit
  • Open the sandwich and remove any vegetables and cold cuts, since you don’t want to warm those up

This method should only be used if you are in a hurry or do not have an oven available. You will not see the best results with the bread in this method, so only use it in an emergency.

  • Flip over the sandwich, and let it heat for 15 seconds more
  • Check to see if it is heated thoroughly
  • Remove from the microwave
  • Add any previously removed vegetables or cold cuts back to the sandwich
