Pat the white fish fillets dry with paper towels to remove excess moisture.

In a shallow dish, mix the all-purpose flour with Old Bay seasoning.

In a second dish, whisk together eggs and buttermilk until smooth.

In a third dish, combine breadcrumbs with any remaining Old Bay seasoning.

Dredge each fish fillet in the seasoned flour, shake off excess, then dip in the egg mixture and finally press into the breadcrumb mixture.

Place coated fillets on a plate in a single layer and lightly spray both sides with cooking spray.

Preheat the air fryer to 400°F (200°C) for about 5 minutes.

Cook the fish in the air fryer for 6-10 minutes, flipping halfway through until golden brown.

Serve hot with French fries, tartar sauce, and lemon wedges.
