Add cod to air fryer basket. Air fry at 380 degrees F for 10-12 minutes, or until panko is browned and cod is cooked through.

Notes
To get a good coating of the panko, make sure to press in as much to the cod as you can before air frying.
While 10-12 minutes works well with most cod, you may need to adjust the cooking time based on the thickness of your cod.
You can use fresh or frozen cod. If using frozen, thaw completely before cooking to ensure the cod cooks properly.
This recipe serves one, but it is easy to double, triple, or quadruple if serving more.
