How to Make Air Fryer Flounder

Preheat the Air Fryer

Get your air fryer going while you prepare the flounder.

Coat the Fish in Dry Spices

Combine the garlic powder, paprika, salt and pepper in a shallow dish. Now, coat the fish on both sides with the spice mixture.

Air Fry the Flounder

Once the air fryer is preheated, coat the basket with nonstick cooking spray.

Then, gently arrange the flounder in a single layer in the air fryer basket. The fillets can be close together as long as they are not touching.

Then, air fry for about 7 minutes.

Finish the Dish

Before serving, squeeze fresh lemon juice and sprinkle the capers over the air fried fish.

Variations

Since flounder is such a mild white fish, lots of different herbs and seasonings work beautifully:

Add some heat: Cajun seasoning, red pepper flakes and cayenne pepper all add some extra spice.
Extra richness: A sprinkle of Parmesan cheese or a pat of butter add a little indulgence to this super clean meal.
Try herbs: Fresh or dried herbs like dill and parsley bring out the natural flavors of the fish.

Storage Instructions

Allow the fish to cool completely before storing. Refrigerate in an airtight container for up to 3 days. Reheat the flounder gently in the air fryer for 2-3 minutes, or in the microwave.

Air Fryer Tips for Success

Always pat the fish dry before seasoning.
Don’t overcrowd the basket.
Use a light coating of oil or nonstick cooking spray for even browning.
Cook fish in a single layer.
Check for doneness a minute early if your fillets are especially thin.

Frequently Asked Questions

Can I use another type of fish?

Absolutely. Cod, haddock, tilapia, sole and other mild white fish all work well with this recipe.

Do I need to flip the fish?

No. Air fryers circulate hot air around the food, so flipping is usually unnecessary for thin flounder fillets.

Can you cook frozen fish in the air fryer?

Yes! Frozen fish can be cooked directly in the air fryer without thawing first. Be sure to increase the cooking time by a few minutes.

How do you know when fish is cooked?

The easiest way to tell is by checking the internal temperature. Fish is safely cooked when it reaches an internal temperature of 145°F in the thickest portion. If you don’t have a kitchen thermometer, visually inspect the fish to make sure it’s opaque and flakes easily with a fork.
