Heat a big non-stick pan over medium heat. Add the olive oil and the onions and cook until the onions are slightly transparent, then incorporate the garlic.

Cut the cod into tiny pieces. Nobody will want to feel a huge chunk of cod in the croquettes. Cook it with the onion and garlic.

When the cod is fully cooked, add the flour and stir well. Then pour the milk and the nutmeg. Stir continuously until a thick dough is formed. Then retire from the stove and let it chill until it’s completely cold.

Form the croquettes with your hands. Immerse the croquettes in egg and then cover with breadcrumbs.

Fry in a pan with enough vegetable oil (preferably sunflower oil) to cover at least half of the croquettes. Fry for 5 minutes until the brown crust is formed.

Serve with your favorite sauce. Enjoy!
