Reheating fried fish in the air fryer works best at lower temperatures to avoid drying out the delicate flesh while restoring crispness to the coating. So how long do i reheat fried fish in the air fryer? In most cases, 6 to 10 minutes at 320°F to 350°F does the job, depending on the thickness of the fillet and whether it was stored in the fridge or freezer.
That short window is all it takes. Go longer and the fish turns rubbery. Go hotter and the breading burns before the inside warms through.
Below you’ll find a full breakdown of times, temperatures, and step-by-step methods that actually work.
Why Air Fryers Are The Best Way To Reheat Fried Fish
A microwave makes fried fish soggy and sad. A regular oven takes forever and can still dry it out. The air fryer sits right in the middle.
It moves hot air around the fish fast, which crisps the coating without overcooking the meat. You get that fresh-from-the-fryer texture back in under 10 minutes.
It also uses less oil and less cleanup. For leftover fish and chips, fish tacos, or a fried fish sandwich, this is the method to use.
How Long Do I Reheat Fried Fish In The Air Fryer
Here are the base times you can rely on. Always preheat your air fryer for 3 to 5 minutes first.
- Thin fillets (under 1/2 inch): 5 to 6 minutes at 320°F
- Standard fillets (1/2 to 1 inch): 7 to 8 minutes at 330°F
- Thick fillets or steaks (over 1 inch): 9 to 10 minutes at 340°F
- Frozen fried fish: 10 to 12 minutes at 350°F, flip halfway
- Fish sticks or nuggets: 4 to 5 minutes at 350°F
Flip the fish once at the halfway mark. This keeps both sides crisp and helps it heat evenly.
If your fish is very thin or already fragile, drop the temp by 10 degrees and check it a minute early. Its better to undercook slightly then overcook.
Temperature Guide For Different Types Of Fried Fish
Not all fried fish behaves the same. The coating and thickness change everything.
- Beer-battered fish: 330°F, 7 to 9 minutes. The batter browns fast, so keep it lower.
- Cornmeal-crusted fish: 340°F, 7 to 8 minutes. Cornmeal crisps up quick.
- Panko or breadcrumb fillets: 320°F, 6 to 8 minutes. Panko burns easily.
- Battered fish from a restaurant: 330°F, 8 to 10 minutes. These tend to be thicker.
- Fish cakes or patties: 340°F, 8 minutes. Flip gently so they don’t crumble.
Fridge Vs Freezer: Does It Change The Time?
Yes, and this trips a lot of people up.
Fish from the fridge is already thawed, so it only needs to warm through and re-crisp. That’s your 6 to 10 minute range.
Frozen fried fish needs more time because the center is solid ice. Add 3 to 5 minutes and keep the temp at 350°F. Don’t thaw it first, that makes the coating mushy.
If you stored the fish in sauce or a container with other wet foods, pat it dry with a paper towel before it goes in. Moisture is the enemy of crisp.
Step-By-Step: How To Reheat Fried Fish In An Air Fryer
Follow these steps and you’ll get consistent results every time.
- Take the fish out of the fridge 5 minutes before cooking. This takes the chill off.
- Pat the surface dry with a paper towel. Remove any excess oil or moisture.
- Preheat the air fryer to 330°F for 3 to 5 minutes.
- Lightly spray the basket with oil. This stops sticking and helps the crust.
- Place the fish in a single layer. Do not stack or crowd the basket.
- Cook for 4 minutes, then flip carefully with tongs or a spatula.
- Cook another 3 to 5 minutes until hot in the center and crisp outside.
- Check the internal temp. It should hit 145°F.
- Rest for 1 minute on a wire rack before serving.
A wire rack keeps the bottom from steaming. If you don’t have one, just serve right away.
Tips To Keep The Coating Crispy
- Never wrap the fish in foil inside the air fryer. It traps steam.
- Spray a thin layer of oil on the coating. It rebuilds the crunch.
- Don’t overcrowd. Air needs to move around each piece.
- Use a meat thermometer instead of guessing.
- Reheat only what you’ll eat. Reheating twice ruins the texture.
Common Mistakes To Avoid
Most people mess up reheated fish in one of three ways.
- Setting the temp too high. Above 375°F the outside burns before the inside warms.
- Cooking too long. Fish is lean and dries out fast. Stick to the times above.
- Skipping the preheat. A cold basket means uneven cooking and a soggy bottom.
Another one: stacking the fish. If you have a big batch, cook in two rounds. It takes longer but the result is far better.
How To Tell When Reheated Fried Fish Is Done
You want two things: a hot center and a crisp shell.
The best test is a instant-read thermometer. Insert it into the thickest part. It should read 145°F.
No thermometer? Press the fish gently. It should feel firm but still flake apart with a fork. If it’s tough or rubbery, you went too long.
The coating should look golden and sound slightly crisp when you tap it. If it’s pale and soft, give it 1 more minute at 350°F.
Storing Leftover Fried Fish The Right Way
How you store it affects how well it reheats.
- Let the fish cool to room temp first. About 20 minutes.
- Wrap each piece loosely in parchment or foil.
- Put it in an airtight container in the fridge.
- Eat within 3 to 4 days for the best texture.
Don’t stack pieces on top of each other. The coating sticks and peels off.
For longer storage, freeze the fish in a single layer on a baking sheet, then move to a freezer bag. It keeps for up to 2 months.
Final Word On Reheating Times
So the short answer to how long you reheat fried fish in the air fryer is 6 to 10 minutes at 320°F to 350°F. Thinner pieces need less time. Frozen pieces need more.
Preheat, flip halfway, and check the internal temp. Do those three things and your leftover fish will taste almost as good as the first time.
Keep the temp low, keep the time short, and don’t walk away from the basket. Fried fish goes from perfect to dry in about 60 seconds.
