Dab or wipe off any sauce that’s on the fish. 

Transfer the leftover fried fish to the air fryer basket. 

Make sure there’s no foil or paper stuck to the fish.

Spray with cooking spray or use a pastry brush to add a bit of oil to the fish.

Heat on a medium-high heat, between 325F to 350F for about 4 minutes. 

Pause and use tongs to flip the fish halfway through to make sure the fish is heated evenly on both sides.

Heat for another two minutes. 

Serve and enjoy!
