Remove the cod from its packaging and place it on a plate or cutting board. Pat off any excess moisture using paper towels. Note: be sure the filets are completely thawed to ensure the fish cooks evenly.

Stir together all of the ingredients for the marinade in a measuring cup or a mixing bowl until well combined.

Place cod filets in a zip lock bag (or sealable container) and pour in the marinade. Seal the bag (or container) and move it around until everything is well-coated in marinade.

Refrigerate at least 30 minutes, up to 10 hours.

When you’re ready to cook the cod, preheat the air fryer to 400 degrees Fahrenheit for 5 minutes.

Transfer the marinated cod filets to the basket of the air fryer and cook for 8-12 minutes (depending on the thickness of the filets), or until the fish reaches an internal temperature of 145 degrees F. For a golden-brown crisp, you may want to cook the filets longer, until they reach your preferred level of crispiness.
