Can You Reheat Sushi?

Can You Reheat Sushi

While under most circumstances I would sit here and write a thousand words on how you better not ever reheat sushi because sushi is usually not good as a leftover dish, today I am giving you tips on how to reheat sushi that is typically served warm.

But to be clear, if your sushi was originally served cold, you should not heat it or reheat it.

But, yes, if your sushi was served warm, you can absolutely reheat it.

In reality, you can reheat any food that has been refrigerated or frozen as long as you use the right approach with the right appliance. For example, foods that have been breaded or fried are typically best reheated in the oven or the air fryer. At the same time, foods that have been grilled or baked are often best reheated back on the grill or in the oven.

When it comes to sushi, if you must reheat it, you are probably going to get the best results from the oven.

Should You Reheat Sushi?

Should You Reheat Sushi

Again, if you are working with raw sushi, no you should not reheat sushi.

However, if you are working with cooked sushi of any kind, you do want to be careful that you are working with fish.

You don’t want to have to worry about getting yourself sick on leftover sushi.

In general, if you are working with day old sushi, you are probably going to be just fine eating cold sushi straight out of the fridge and reheating any cooked sushi to “just crispy.”

However, you should always be careful to do your own research to be sure to cover all your bases. To get you started on that research, check out this article on reheating leftovers by Healthline

How to Reheat Sushi in the Oven

Reheating sushi in the oven is only recommended for tempura or a baked roll, and you should only flash heat it, so you get a quick crisp. You do not need to heat the sushi all the way through.

  1. Line a baking sheet with aluminum foil.
  2. Place your sushi on the baking sheet and set the oven to the broil setting.
  3. Flash broil the sushi for 30 seconds to a minute or until crispy on the outside.
  4. Serve with soy sauce, wasabi, and pickled ginger and enjoy!

How to Reheat Sushi in the Microwave

I’m not going to lie, this one is impossible.

You should never reheat your sushi in the microwave regardless of the type of sushi we are talking about.

The only exception to this rule would be if we are discussing miso soup, which is often served with sushi.

In this case, place your miso in a bowl and microwave it on full power for about a minute.

That should get your broth up to warm enough to enjoy.

How to Reheat Sushi in an Air Fryer

If you’re reheating sushi in an air fryer, be sure you are reheating only sushi that already has a crispy exterior.

  1. Set your air fryer to 400 degrees Fahrenheit.
  2. Place your sushi pieces into the air fryer, so they are not touching.
  3. Heat for 1-2 minutes, just to get them warm and crispy on the outside.
  4. Serve with soy sauce, wasabi, and pickled ginger and enjoy!

How to Reheat Sushi on a Grill

Don’t do it.

Usually, I would talk about how you can use the grill if you’re already working on it to reheat pretty much any leftovers you have on hand.

In this case, there is virtually no sushi that would be served by being heated on a grill, so your best bet is to avoid this appliance altogether when dealing with sushi. It would be much better off cold, even if it was originally warm.

The danger you run is warming up your seaweed, which will make it tough and hard to bite through.

Just don’t do it.

How to Reheat Sushi in a Toaster Oven

Reheating sushi in a toaster oven will be much like using the oven.

  1. Heat the toaster oven to the broil setting.
  2. Place your tempura or baked sushi pieces on a lined baking sheet.
  3. Flash broil your sushi pieces under the broiler for 30 seconds to a minute or until crispy on the outside.
  4. Serve and enjoy!

How to Reheat Sushi in a Pan on the Stove

Reheating sushi in a pan on the stove is tricky, and it might be more work than it’s worth.

  1. Place a cast iron skillet on the stove and layer about an inch of coconut oil or avocado oil in the pan and heat it to medium heat.
  2. When the oil is hot, place the sushi pieces only on the edges, just to crisp up the outsides on all sides.
  3. Serve and enjoy!

Winner! – The Best Way to Reheat Sushi Is Using the Oven

Again, there is no great way to reheat a food that is typically best served cold, but in this case, the broil setting in the oven is going to be your best bet for flash heating the outside of an already cooked sushi like tempura or a baked roll.

Of course, if you’re dealing with a dish like chicken Katsu or teriyaki chicken, you can of course reheat those dishes as you would any other chicken dish or fried dish. But as this is an article about sushi, I am sticking to the classic rolls.
