Created in 19th-century Lisbon, named for a tavern keeper called Brás (or Braz) in the Bairro Alto district. It belongs to a family of bacalhau-and-leftovers dishes — salt cod was the cheap protein that fed Portugal for 500 years after the Newfoundland fisheries opened in the 1500s, and street cooks improvised this version using the previous day's fried potatoes.
Named for a 19th-century tavern keeper called Brás in Lisbon's Bairro Alto, built on the day's leftover fried potatoes. The egg goes in last off direct heat and is folded, never stirred—rubbery egg means it cooked off the pan.
Salt cod shredded into threads, tangled with matchstick fried potatoes and just-set scrambled egg — the egg should still be glossy, almost wet, binding everything without cooking dry. Black olives and chopped parsley on top. One forkful gets you fish, potato, egg in the same bite. If the egg is rubbery, it overcooked off the heat.
Timing is the only hard part: the egg goes in last, off direct heat, and gets folded — never stirred — so it sets in soft curds around the cod and potato. Restaurants that pre-cook everything and reheat get rubbery cod and dry egg. The potato must be freshly fried and crisp when it meets the pan, or it absorbs egg liquid and turns to mush.
Variations
Brás style uses matchstick batatas palha and soft scrambled egg; bacalhau à Zé do Pipo binds with mayonnaise and bakes the top; bacalhau com natas swaps in cream sauce; bacalhau à Margarida da Praça keeps the structure but adds chouriço.
On the Palate
Where Bacalhau à Brás sits in the Portuguese flavor cloud
Kill the heat before the beaten egg goes in and fold — never stir — so it sets in soft, creamy curds that bind the cod and potato; leave the pan on the flame and you get dry, scrambled rubber.
Ingredients
How it's made
6 steps · 25 min active + 1 day waiting
- 10 min
Soak the salted cod in cold water for 24 hours, changing the water several times to remove excess salt.
- 210 min
Peel and cut the potatoes into matchstick-sized pieces. Fry them in hot oil until golden and crispy, then drain on paper towels.
Watch outFry the matchstick potatoes until crisp and golden, then drain hard — any that stay soft will sog out the whole dish.
- 35 min
In a large skillet, heat olive oil over medium heat. Add sliced onions and sauté until soft and translucent, about 5 minutes.
Watch outDon't let the oil smoke; adjust the heat if necessary to keep it at medium.
- 43 min
Add the soaked and shredded cod to the onions, stirring gently until the fish is heated through and flaking easily, about 3 minutes.
Watch outWarm the cod just until it flakes and loosens, about 3 minutes; overcook now and it goes tough before the egg even hits.
- 55 min
Reduce the heat to low and pour in beaten eggs, stirring constantly until the eggs are just set and creamy, binding the cod and potatoes together.
Watch outOff the heat, fold the egg through and stop the moment it turns creamy and clings — it must not fully scramble.
- 62 min
Garnish with chopped parsley and black olives before serving.
