Potatoes are thinly sliced and fried until golden brown, then added to the codfish mixture. Finally, beaten eggs are poured over the mixture and cooked until set. The dish is garnished with olives and parsley before serving. Bacalhau à Brás is a flavorful and hearty dish that is often enjoyed as a main course in Portugal.
