Usually, you should eat your Subway sandwich when you first purchase it, as the sandwich will be in the best condition.

However, you can eat a Subway sandwich up to three days after purchase if you store it in the refrigerator.

Can You Leave a Subway Sandwich Out?

It is not recommended to leave a Subway sandwich out of the refrigerator if you wish to consume it, especially if it contains meat or fish.

According to the United States Department of Agriculture, it’s dangerous to eat cold cuts, meats, vegetables, and other perishables that have been at room temperature for more than two hours.

To keep your Subway sandwich safe, ensure it goes in the refrigerator within two hours.

Also, bacteria growth may impact the flavor and texture of your Subway sandwich.

If your Subway sandwich does not smell or taste right after being stored in the fridge, do not eat it, as it may have gone bad.

How Do I Store a Subway Sandwich in the Fridge?

To extend the shelf life of your Subway sandwich, Subway recommends you wrap your sandwich in two layers of plastic wrap, including the outer paper wrap.

With that, securing your sandwich and ensuring it’s airtight can help your sandwich last for up to three days in the refrigerator.

After preparing your sandwich for the freezer, your Subway sandwich should last for up to three months in the freezer.

To defrost your Subway sandwich, transfer it from the freezer to the refrigerator the day you plan to consume it.

However, it’s not recommended you reheat a frozen Subway sandwich as it can cause unwanted bacteria to grow and spoil your sandwich.

Can You Reheat a Subway Sandwich?

If you prefer your Subway sandwiches warm, you can reheat your Subway sandwiches in several ways.

Reheat Your Subway Sandwich in the Oven

The oven is perhaps the best way to reheat your Subway sandwich.

However, if you have sauces such as mayonnaise on your Subway sandwich, it’s recommended you don’t reheat it.

Ensuring your oven is at 350°F, place your Subway sandwich on a sheet pan and cook in the oven for ten minutes.

Also, if your Subway sandwich contains a lot of vegetables, reduce the cooking time to five minutes.

If your Subway sandwich is not thoroughly cooked after ten minutes, continue to reheat for an additional two minutes.

Reheat Your Subway Sandwich in a Toaster Oven

To heat your Subway sandwich in a toaster oven, first, cover your Subway sandwich in aluminum foil.

Then, heat your toaster oven to 350°F, and cook your Subway sandwich for ten minutes.

After five minutes in the toaster oven, flip your Subway sandwich to the other side for even toasting.

Reheat Your Subway Sandwich in the Microwave

Finally, you can reheat your Subway sandwich in the microwave, which is the quickest method.

To successfully reheat your sandwich in the microwave, cover your Subway sandwich in a paper towel and heat it on full power for around 80 seconds.
