Spray the fish sticks with the oil and spray or brush the bottom of the air fryer basket. Place the fish into the basket and air-fry at 400ºF for 6 minutes, turn the fish sticks over, and air-fry for another 2 to 4 minutes.
You can coat all the fish sticks and then freeze the coated fish sticks for cooking at a later date. When you do decide to cook them, just add 2 minutes onto the cooking time.
