The outsides can be coated with various things such as tempura batter (usually a mixture of flour, water and seasonings) or breading (crumbs, flour, or cornmeal with spices). Submerged into oil will give you a very crispy outside vs. pan fried will give you a similar result but with fewer calories. Both are delicious on day one but how do you enjoy it again the next day?

How to Reheat Leftover Fish
This isn’t just great for frozen fish sticks in air fryer, though that is the bomb too. First off we need to talk about how to store leftover fish first though right? If not done right you won’t get the optimal result when enjoying again the next day. Storing properly you can maintain its quality and safety for later consumption.
Always allow to cool to room temperature for no more than two hours after cooking. Do not leave it out at room temperature for an extended period, as it can promote bacterial growth. If you have a large whole fish or fillets, consider saving them in individual serving bags. This makes it easier to reheat only what you need later.
- Place the leftovers in an airtight container that is appropriate in size for the amount you have.
- You can also use resealable plastic bags designed for food storage. I recommend putting a paper towel or parchment paper in between each beer battered fish piece to prevent sticking.
- Press out as much air as possible to prevent oxidation and freezer burn.
- If you plan to consume within a day or two, store it in the refrigerator. Keep the container tightly sealed to prevent odors from spreading to other foods.
If you had a Fish Fry but don’t plan to eat what’s left within a couple of days, you can freeze it for longer-term storage. Wrap tightly in plastic wrap or aluminum foil before placing it in an airtight container or a resealable freezer bag. Label the container or bag with the date so you can keep track of how long it has been in the freezer.
Store in the refrigerator at a temperature of 40°F or lower. Consume within 1-2 days. Store the wrapped and sealed fish in the freezer at 0°F (-18°C) or lower. Can be kept for several months, but it’s best when used within 2-3 months to maintain quality. Cooking Frozen fish is best when thawed first but can be done right out of the freezer too.
Reheating Fish in the Air Fryer
Just like when Reheating Chicken Tenders in Air Fryer, keep in mind that reheat times may vary based on the size and thickness of the fish fillets, as well as the specific model of your hot air machine. It’s best to check often to prevent overcooking and drying out.
- Preheat your air fryer to 380° F for 5 minutes.
- When you read about How to Reheat Food in Air Fryer this beginning step always helps ensure even heating and better results.
- Place the leftover fried fish in a single layer in the air fryer basket. Do not overcrowd the basket; leave some space between the pieces for hot air circulation.
- Put fillets in the preheated air fryer and air fry for about 3-4 minutes cook time.
- The exact time can vary depending on the thickness of each piece and the air fryer model, so keep an eye on it.
- After about half of the reheating time has passed, flip the fish pieces and spray lightly with olive oil to ensure even heating on both sides.
- if it isn’t crisp enough for you flip again, spray lightly on that side and add 1 more minute.
- Once heated through until internal temperature reaches 145 degrees Fahrenheit and crispy to your liking, remove it from the basket, and serve immediately.
You can Reheat Chicken Wings in Air Fryer this same way! It is a convenient way to bring back foods delicious crispy texture. Always be cautious not to overheat though, as all foods can dry out if cooked for too long. As opposed to heating on a baking sheet this method will get it crispier for sure. Yes the microwave is safe to heat too but will yield a rubbery texture, no good.
How do you reheat fried food and keep it crispy?
This is tough but has been solved with the invention of this hot air machine. Storing it initially is essential to the overall success too which is why we went into that in detail above. Using a Cosori or Ninja Foodi with the air crisp feature you can now bring back to life the crunchy nature that was the there the night before.
If you compare it to heating in a pan, in the oven, or the microwave there will be NO question that this is by far the only way to go. To get the crunch back it is a mixture of very hot air, space for circulation, a bit of olive oil on the outside (but just a bit), and flipping each piece over for even cooking.
We will explain the best way to reheat fish in air fryer here. Alternatively you can preheat your oven or toaster oven to a low temperature, around 275°F. Place on an oven-safe dish or baking covered loosely with aluminum foil for about 10-15 minutes until warmed but air frying is the best by far.
If you don’t finish what you have reheated at that point you will have to discard at this time. Unless you can chop it up and reuse within an hour in a different way it shouldn’t be cooled and reheated a second time. It is a one and done trick that works well but shouldn’t be done a second time or bacteria may not make it safe to eat again.

Reheat Frozen Fish in Air Fryer
- Preheat your air fryer to 380° F for 5 minutes. Preheating helps ensure even heating and better results. Place the leftover fried fish in a single layer in the air fryer basket. Do not overcrowd the basket; leave some space between the pieces for air circulation.
- Cook for about 3-4 minutes total until warmed on inside and crispy on outside. The exact time can vary depending on the thickness of each piece and the air fryer model, so keep an eye on it.
- After about half of the reheating time has passed, flip the pieces over and spray lightly with olive oil spray to ensure even heating on both sides. After 4 minutes or so total if it isn't crispy enough, flip over once more, spray lightly with olive oil spray on the other side and air fry 1 more minute or until crispy to your liking. Do not overheat or it will dry out in the middle.
- Once heated through and crispy to your liking, remove it from the air fryer, and serve immediately.
