Reheating fried fish to make it crispy and fresh again can become a dilemma.

Rewarming in the oven may be time-consuming. The stove method risks breaking it, and the microwave often leaves it disappointingly soggy, ruining its sought-after crispiness.

However, one method promises to give you the best of both worlds: crunchy fish without breaking it.

The air fryer method. So, today, let’s talk about how you can use your favorite air fryer for re-crisping fried fish.

To reheat fried or battered fish in an air fryer, arrange fish pieces in a preheated air fryer. Cook the fish at 320F for 4-5 minutes, turning them over after 2-3 minutes.

Steps To Reheat Fried Fish In An Air Fryer

  • Preheat the air fryer to 320F.
  • Arrange the fish filets in your air fryer basket without overlapping.
  • Add a few sprays of extra virgin olive oil to enhance the texture and flavor.
  • Cook the fish for about 4-5 minutes, turning it over when halfway through the cooking time.
  • Once the timer elapses, check the fish. If you want an extra crispy exterior, use the broil setting on your air fryer and cook for 1-2 additional minutes.
  • Spritz the fish with lemon juice before serving to enhance flavor.


If you are reheating frozen fish or cold fish, the reheating time may slightly increase (2 to 4 minutes).

Therefore, always adjust the cooking time according to the condition of the fish. 

If you are reheating other types of seafood, such as shrimp and prawn, the above-mentioned time and temperature settings may not apply.

Reheating Fish In Microwave Vs Air Fryer

The main difference between refreshing fish in an air fryer Vs a microwave is the reheating time and the resulting texture of the fish.

Depending on the thickness and quantity of the fish, the microwave takes only 1-2 minutes to rewarm it completely.

However, if the fish is battered or breaded, the exterior may become too soggy, making the taste unpalatable.

Conversely, fish warmed in an air fryer results in a crispy exterior akin to fresh. However, the cooking time can be slightly longer.
