To make this air fryer fish recipe, preheat your air fryer at 400° F (190° C) for at least 10-15 minutes.
Meanwhile, mix the seasonings together in a bowl. Pat fish dry and apply seasoning on both sides, pressing down to stick on the surface.
Grease the air fryer basket either by spraying no stick cooking spray or by brushing it with a vegetable oil such as olive oil. Cook in a single layer for 8-10 minutes (depending on the size or thickness of the fillets), flipping halfway through with a silicone spatula if you can. Large fillets or small air fryers will not permit that. But the fish will still cook without problems!
If needed, cook them in batches, leaving a space between the fillets for hot air to circulate and cook them evenly. They have cooked fully when they show a brown exterior and are flaky in the thickest part. You can also take their internal temp with a meat thermometer-- it must reach 145° F (63° C).
Transfer them to a plate, squeeze fresh lemon juice over them, and sprinkle chopped parsley on top. You may serve with homemade tartar sauce or no sauce at all!
