Choose cod fillets of similar thickness for the most even cooking, and check thinner pieces earlier to prevent overcooking.

For frozen cod, thaw completely and pat dry before adding the oil and seasonings.

For extra heat, add cayenne pepper or crushed red pepper flakes to the seasoning mixture.

For smoky flavor, substitute smoked paprika for regular paprika.

Dried parsley, dill, thyme, oregano, or Italian seasoning can be added for extra herb flavor.

For a richer finish, brush cooked cod with melted butter and fresh lemon juice.

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Reheat in the air fryer at 350°F (175°C) for a few minutes, checking frequently to avoid drying out the fish.
