How To Reheat A Subway Sandwich – Don’t Waste The Bread and Its Fillings!

Countless food lovers adore Subway sandwiches, as they offer tons of delicious toppings and combinations. While you could eat leftover Subway at room temperature, many people wish they could reheat and revive their leftover sandwich’s former state. 

Reheating sandwiches using the wrong methods can lead to chewy or dry fillings and soggy bread. Thankfully, there are quite a few ways to reheat Subway sandwiches while keeping top-notch toppings and light, fluffy bread. 

Subway sandwiches can be reheated in an oven, air fryer, toaster oven, on the stove, or in the microwave. Many sandwich types can be reheated as a whole, but some sandwiches will need the filling and bread to be reheated separately. 

How To Reheat A Subway Sandwich

Reheating A Subway Sandwich

Reheating Subway sandwiches only takes a few minutes and basic kitchen equipment, although all methods require attention to detail. It takes more time when the sandwich is topped with meat and less time when it has more vegetables. 

Separating the bread from the toppings before reheating may have the best results in some cases. One could also use a combination of reheating methods, such as using an oven to reheat bread while using the stove to reheat meat toppings. 

1. How To Reheat A Subway Sandwich In The Oven

Using an oven to reheat Subway sandwiches is the most effective and simplest method. Some toppings should not be placed in the oven, but this method is great for creating crispy bread and sizzling melted cheese

To reheat a Subway sandwich in the oven:

  1. Preheat the oven to 350°F.
  2. Remove the cold toppings, like lettuce, tomatoes, etc. (optional)
  3. Place the sandwich on a heat-safe baking rack above a baking sheet. This step will allow the sandwich to heat from all sides while catching drips.
  4. Reheat for 8-10 minutes, checking after 6 minutes. 
  5. Check the internal temperature.
  6. Reassemble the sandwich (if necessary).

2. How To Reheat A Subway Sandwich In An Air Fryer

Using an air fryer is a great alternative, as it will reheat Subway sandwiches in short timeframes. This method is quick and convenient, but will still revive the quality and texture of the sandwich. 

To reheat a Subway sandwich in an air fryer:

  1. Set the air fryer to medium-high. 
  2. Take out fragile sandwich fillings, such as lettuce, excess sauce, egg, etc.
  3. Place the sandwich in the air fryer’s basket attachment. 
  4. Reheat it for 3-5 minutes.
  5. Check the internal temperature. 
  6. Continue heating, if necessary.
  7. When done, reassemble the sandwich.

3. How To Reheat A Subway Sandwich In A Toaster Oven

A toaster oven can ensure that the bread is delightfully crispy while heating the toppings to a pleasant temperature. However, one would need to watch closely as toaster ovens could overcook or dry out the sandwich. 

To reheat a Subway sandwich in a toaster oven:

  1. Set the toaster oven to 350°F.
  2. Remove fragile sandwich fillings.
  3. Place the sandwich on a baking sheet.
  4. Reheat it for around 4 minutes.
  5. Flip the sandwich and reheat it for another 4 minutes.
  6. Remove the sandwich, unwrap it, and return the removed fillings.

4. How To Reheat A Subway Sandwich On The Stove

Using the stove to reheat a leftover sandwich is a classic method, but it generally works better for sandwiches that haven’t been in the fridge. This method works well with cast iron pans and skillets.

To reheat a Subway sandwich on the stove: 

  1. Coat the pan with oil spray or butter.
  2. Unwrap the sandwich.
  3. Remove any toppings that you want to remain cold, like lettuce, tomatoes, etc.
  4. Place the sandwich in the pan, cover and heat for 2-3 minutes.
  5. Flip the sandwich and reheat for another 2-3 minutes.
  6. Check the internal temperature with your fingers and remove when the internal temperature is to your liking.
  7. Remove when the insides are heated and the bread is crispy. 
  8. Reassemble the sandwich.

5. How To Reheat A Subway Sandwich In The Microwave

Microwaving sandwiches is not the best option, but it can be done if you are short on time or have limited kitchen equipment. The sandwich will need to be reheated in short intervals to prevent the bread from becoming too soggy or chewy. You could also try reheating the fillings and the bread separately, as microwaving could still result in cold spots. 

To reheat a Subway sandwich in the microwave: 

  1. Remove foil and place the sandwich in a microwave-safe plate.
  2. Remove fragile toppings and excess sauce.
  3. Wrap a paper towel around the sandwich to absorb excess moisture.
  4. Microwave the sandwich for 60 seconds, checking it every 20 seconds.
  5. Check the internal temperature. Microwave for another 20 seconds if needed.

Frequently Asked Questions

Do you still have questions about reheating Subway sandwiches? We’ve got answers!

How do I store a reheated subway sandwich?

A reheated Subway sandwich can be wrapped in foil and stored at room temperature for a couple of hours to preserve its quality. However, leftover sandwiches should be transferred to the refrigerator for more extended periods. (If your sandwich has been left out for 2 hours, it should be eaten immediately and not stored in the fridge to eat in the future, as it can be dangerous to eat due to growing bacteria.)

Can I reheat a subway sandwich multiple times?

One could reheat a Subway sandwich multiple times if it is still safe for consumption. However, it is not recommended since the bread may become soggy or chewy, and the toppings could become tarnished. Note: If you do reheat a sandwich more than once, you would need to refrigerate it immediately to cool it down and prevent bacteria from proliferating.

How long does it take to reheat a subway sandwich? 

Reheating a Subway sandwich takes 5-10 minutes. Ovens take longer to reheat sandwiches, as preheating takes time. Microwaves and stovetops are the fastest. Using an air fryer will take around 5 minutes and create amazing results.
