The codfish is first soaked to remove the salt, then cooked with onions until tender. The potatoes are fried until golden brown and crispy. Finally, the beaten eggs are added to the pan and cooked until they form a creamy texture. Bacalhau à Brás is a flavorful and satisfying dish that is often served with a side of olives and a fresh salad.
