Cut the cod or Alaska pollock into pieces, then finely chop it.

In a bowl, combine the chopped fish, egg, breadcrumbs, flour, lemon juice, parsley, salt, and pepper. Mix until you have a smooth, even mixture to use for shaping the croquettes.

With clean hands, shape the mixture into fish croquettes.

Cook the fish croquettes in an air fryer with a little olive oil at 400°F (200°C) for 12 minutes.

Serve your delicious fish croquettes with a squeeze of lemon juice.

Enjoy your meal!
