Coat the air fryer basket with grapeseed oil spray and place the frozen fish fillets into the basket.
Spray with another coat of grapeseed oil spray.
Cook in the Air Fryer at 390*F for 12-15 minutes or until the fish flakes easily with a fork and is fully cooked. It is best to flip the fillets halfway through the cooking time. The internal temperature should be at least 145*F before serving.
Carefully remove and serve.
Notes
As all air fryers are different and so is the thickness of the cod, be sure to check the internal temperature before serving.For the Hook Line and Savour Fish Fillets found at Costco, these are already breaded, this took 15 minutes to reach the 145*F, placing them in the air fryer frozen and not preheated. I used a Ninja Air Fryer.
