History of Cod à Bras
Cod à Bras was born in Lisbon in the mid-19th century, in a tavern in the Bairro Alto district run by a cook known as "Bras." Legend has it that this innkeeper devised the dish as a creative solution to use up leftover salted cod at the end of the day. He mixed it with very thinly cut potatoes, sautéed onion, and lightly scrambled eggs, creating a combination that delighted his patrons and quickly spread through the taverns of the Portuguese capital.
Portugal has a relationship with salted cod that is unmatched by any other European country. Portuguese people call it fiel amigo (faithful friend) and boast of having more than a thousand different recipes for preparing it. The cod tradition began in the 15th century with fishing expeditions to Newfoundland, and for centuries it was the staple food of Lent, humble families, and sailors. Of that thousand recipes, à Bras is probably the one that best represents popular Lisbon cuisine: cheap ingredients, simple technique, and a result that transcends the sum of its components.
In Spain, cod à Bras has gained popularity in recent decades, especially in Galicia, Extremadura, and areas bordering Portugal. It has also become a common dish in signature tapas in cities like Madrid and Barcelona, where it is served in small portions as a starter or gastronomic tapa.
What Makes Cod à Bras Unique
The greatness of cod à Bras lies in the contrast of textures and the technique of setting the egg. Three main ingredients (shredded cod, crispy straw potatoes, and egg) are transformed into something greater than the sum of their parts when executed with precision. The potatoes provide crunch, the cod provides saltiness and depth of flavor, and the egg binds everything with a silky creaminess that coats every bite.
Unlike other Portuguese cod dishes, such as Bacalhau com Natas which is baked, or Gomes de Sá which is prepared with boiled potato, à Bras is cooked entirely in a pan in less than ten minutes once all the elements are prepared. It is a last-minute dish, quick to execute and immediate to serve, making it ideal for both a weeknight dinner and for impressing guests without complications.
Onion, although sometimes omitted from the main ingredient lists, is fundamental. Slowly sautéed in olive oil until sweet and translucent, it acts as the aromatic base upon which the entire dish is built. Without a well-sautéed onion, à Bras loses half its charm.
Ingredients for 4 People
- 400 g of desalted and shredded cod — skinless and boneless, in small, uniform flakes
- 400 g of potatoes — cut into very thin matchsticks (2-3 mm) or quality bagged straw potatoes
- 6 large eggs — at room temperature
- 2 medium onions — thinly julienned
- 3 cloves of garlic — sliced or finely minced
- Extra virgin olive oil — generous amount, about 80-100 ml
- 12-15 Portuguese black olives — for garnish
- Fresh parsley — finely chopped, a good handful
- Salt — use with caution, as the cod already provides saltiness
- Freshly ground black pepper
For optimal results, use quality desalted cod that you can shred yourself, or pre-shredded cod flakes. Good cod makes all the difference in a dish where there are no sauces to mask the raw ingredients. If you need to desalt your own piece, consult our guide on how to properly desalt cod.

Step-by-Step Recipe
- Prepare and fry the straw potatoes: peel the potatoes and cut them into 2-3 millimeter thick strips using a mandoline or a sharp knife. Dry them with paper towels. Heat plenty of mild olive oil (or sunflower oil) to 180°C and fry the potatoes in small batches for 2-3 minutes until golden and crispy. Drain them on absorbent paper and set aside.
- Sauté the onion: in a wide, deep pan (preferably non-stick, 28-30 cm), pour a good drizzle of extra virgin olive oil. Add the thinly julienned onion and cook it over medium-low heat for 15-20 minutes, stirring occasionally, until it is completely transparent, soft, and sweet. Do not rush this step.
- Add the garlic: when the onion is ready, add the sliced garlic and sauté for two more minutes until fragrant but not browned.
- Sauté the cod: increase the heat slightly to medium. Add the shredded cod to the sautéed mixture and stir for 3-4 minutes to combine with the onion and absorb the flavors. The flakes should be thoroughly heated but not dried out.
- Add the straw potatoes: incorporate the fried potatoes into the pan and mix with gentle movements to avoid breaking them too much. Lower the heat to medium-low.
- Pour in the eggs: lightly beat the eggs in a bowl (so that strands of white and yolk are visible, not a homogeneous mixture). Pour them over the cod and potato mixture. Immediately stir with a wooden or silicone spatula, using constant, folding motions for 2-3 minutes. The egg should partially set, becoming creamy, glossy, and slightly moist.
- Serve immediately: remove the pan from the heat when the egg still looks a little runny (the residual heat will complete the cooking). Divide into warm plates, sprinkle with chopped fresh parsley, and garnish with black olives.
Straw Potato Technique
Straw potatoes are the element that visually distinguishes cod à Bras from any other dish. They should be cut into strips no thicker than 3 millimeters, as uniform as possible so that they fry evenly. The ideal tool is a mandoline with a julienne attachment, although a sharp knife with patience yields an equally valid result.
Once cut, it is essential to wash them in cold water to remove excess starch and then thoroughly dry them with a kitchen towel or absorbent paper. Residual moisture causes splattering when frying and, worse, prevents the potatoes from becoming crispy. Fry them in small batches at 180°C: if you overload the pan, the temperature drops and the potatoes absorb oil instead of browning.
In Portugal, many home cooks directly use bagged straw potatoes bought from supermarkets, and restaurants themselves do not consider it heresy. If you opt for this alternative, choose a quality brand with simple ingredients (potato, oil, and salt) and add them at the last moment to maintain their crispiness. The advantage of making them homemade is that they are less dry and integrate better with the creamy egg.
The Creamy Point of the Egg
This is the step that separates an ordinary cod à Bras from an extraordinary one. The technique is similar to French scrambled eggs: low heat, constant movement, and remove before your instincts tell you to. The egg should have a silky, glossy, and slightly wobbly texture, never dry or set into firm lumps.
The most common mistake is using too high heat. At high temperatures, the egg sets in seconds, forming dry, rubbery fragments that stick to the potatoes without binding them. Over medium-low heat, the egg distributes evenly and coats each cod flake and each potato stick in a thin, creamy layer. You must stir constantly with a wide spatula, making folding motions from the edges towards the center.
The golden rule is to remove the pan from the heat when the egg still seems too wet. The residual heat from the pan, potatoes, and cod will continue to cook the egg during the minute it takes to serve. If you wait for it to look ready in the pan, it will be overcooked on the plate. It is preferable to undercook slightly and serve immediately.
Comparison of Portuguese Cod Dishes
Portugal has dozens of classic cod preparations, each associated with a region, a history, and a different technique. Below we compare the four most emblematic to understand what distinguishes à Bras from the rest.
| Dish | Origin | Key Ingredients | Technique | Final Texture |
|---|---|---|---|---|
| Bacalhau à Brás | Lisbon (Bairro Alto) | Shredded cod, straw potatoes, eggs, onion, olives | Pan-fried, creamy scrambled egg | Creamy, crispy, loose |
| Bacalhau com Natas | Northern Portugal | Shredded cod, cream, fried potatoes, onion, béchamel | Oven-baked, au gratin with cream and cheese | Gratinated, melting, rich |
| Bacalhau à Gomes de Sá | Porto | Cod flakes, boiled potato, onion, hard-boiled egg, olives | Oven-baked, layered assembly | Firm, juicy, baked |
| Bacalhau Espiritual | Convent, central Portugal | Shredded cod, sandwich bread, milk, carrot, béchamel | Oven-baked, béchamel-based soufflé type | Spongy, light, gratinated |
À Bras is the only one of the four great dishes that is entirely cooked in a pan and served immediately. This immediacy is both its greatest virtue (a dish ready in minutes) and its limitation (it does not tolerate waiting or reheating). In contrast, Gomes de Sá or Bacalhau com Natas can be assembled in advance and baked at the last minute, making them more practical for meals with guests.
Pairing and Accompaniment
Cod à Bras is a self-sufficient dish that rarely needs a side dish, but the right wine and accompaniments can elevate the experience. The classic pairing in Portugal is a white, young, and slightly sparkling Vinho Verde, whose fresh acidity cuts through the richness of the egg and fried potatoes. Other excellent Portuguese options include a full-bodied Alvarinho from Minho or a white wine from Dão.
If you prefer Spanish wines, an Albariño from Rías Baixas works perfectly for the same aromatic logic: minerality, lively acidity, and citrus notes that cleanse the palate. A Godello from Valdeorras or a young Verdejo from Rueda are also good alternatives. Avoid wines with too much oak or body, as they will compete with the subtlety of the dish.
As for accompaniments, it is common in Portugal to serve à Bras alone, perhaps with a simple green salad dressed with olive oil and wine vinegar. Some restaurants serve it with a few slices of ripe tomato. You can complete a Portuguese meal with a starter soup, such as the classic caldo verde, and a dessert like pastéis de nata.
Nutritional Information
Cod à Bras is a nutritious and energetic dish thanks to the combination of protein from cod and egg with carbohydrates from potato. Below are the approximate nutritional values per serving.

Cod is one of the leanest protein sources from the sea, with barely 1% fat. Eggs provide complete protein and B vitamins, while olive oil adds healthy monounsaturated fats. If you want to reduce calories, use fewer potatoes and more cod, and sauté the onion with less oil.
Variants of Cod à Bras
The original recipe allows for adaptations that respect the essence of the dish without betraying it. In Portugal, each family has its version with small nuances, and some modern restaurants have created variants that are already classics in their own right.
À Bras with shrimp: replace half the cod with peeled, raw shrimp. Add them to the pan a minute before incorporating the eggs so they cook just right. The combination of the cod's saltiness with the shrimp's sweetness is exceptional. It is the most popular variant in restaurants on the Algarve coast.
À Bras with peppers: add very thinly sliced red and green bell peppers to the onion sauté. Cook them together during the last five minutes of sautéing. They add color, a touch of sweetness, and a slightly crunchy texture that complements the straw potatoes. This is a common version in Alentejo.
Mushroom À Bras: for a fish-free version, replace the cod with a mix of mushrooms (button, shiitake, and oyster mushrooms), sautéed beforehand with garlic until they release all their water and brown. It is not an à Bras in the strict sense, but the concept works well and is an option for vegetarians. You can also explore our leftover cod flake recipes for ideas.
Where to Eat Cod à Bras in Lisbon
If you visit Lisbon and want to try a benchmark cod à Bras, there are several establishments renowned for their version of the dish. Cervejaria Ramiro, on Avenida Almirante Reis, is famous for its seafood but prepares an impeccable à Bras as a starter. In the Alfama district, Tasca do Chico serves a traditional tavern version with live fado. Solar dos Presuntos, near Praça dos Restauradores, is one of Lisbon's most famous restaurants, and its à Bras has been a benchmark for decades.
For a more modern experience, chef José Avillez's Belcanto, with two Michelin stars, offers a deconstructed version of à Bras that respects the original flavors but reinvents the presentation. However, for many Lisboetas, the best à Bras is eaten at home, prepared by grandma with a worn pan and without measuring ingredients. This dish, like so many popular recipes, improves with practice, confidence, and the intuitive touch of someone who has been making it all their life.

Frequently Asked Questions
What is the origin of the name "à Bras"?
The name comes from the innkeeper Bras (or Brás in Portuguese), who ran a tavern in Lisbon's Bairro Alto district in the mid-19th century. According to oral tradition, Bras invented the dish to use up leftover salted cod by combining it with fried potatoes and eggs. Its success was such that customers began to ask for the dish by the cook's name, and thus the denomination was solidified.
Can cod à Bras be reheated?
Technically yes, but the result loses a lot of quality. The straw potatoes soften and lose their crispiness, and the egg dries out when reheated. If you have leftovers, the best option is to reheat it over very low heat in a pan with a drizzle of olive oil and a tablespoon of water, covered, for two or three minutes. Even so, it won't be as good as freshly made, so it's best to calculate quantities well.
Can I use store-bought bagged straw potatoes?
Yes, and many Portuguese people regularly do so at home without any reservations. Bagged straw potatoes save a lot of time and give an acceptable result, although their texture is slightly drier and crispier than homemade ones. Choose a brand with simple ingredients and add them to the pan at the last moment to keep them crispy before mixing with the egg.
What is the difference between cod à Bras and cod à Gomes de Sá?
They are two completely different dishes in technique and result. À Bras uses shredded cod, fried straw potatoes, and creamy scrambled egg, all cooked in a pan. Gomes de Sá uses large cod flakes, sliced boiled potato, onion, hard-boiled egg, and olives, assembled in layers and baked. The first is creamy and quick, the second is heartier and can be prepared in advance.
Can cod à Bras be made with fresh cod?
It can, but the result will not be the same. Salted cod has a firmer texture and a more concentrated flavor that allows it to be shredded into strands that integrate perfectly with the potatoes and egg. Fresh cod is moister and breaks into soft pieces, losing that characteristic texture. If you still want to try it, lightly roast the fresh cod before shredding it to reduce moisture.
How many calories are in a serving of cod à Bras?
A standard serving provides approximately 420 to 460 kilocalories, depending on the amount of oil used for frying the potatoes and sautéing the onion. It is a protein-rich and energetic dish thanks to the combination of cod, eggs, and fried potatoes. To lighten it, you can reduce the proportion of potatoes and increase the cod, or use the technique of baking the potatoes with a little cooking spray until crispy.
What type of cod is best for à Bras?
Ideally, good quality desalted salted cod, preferably from the loin or center, which has long fibers and shreds well. Avoid tail cuts, which are thinner and fall apart too much. The cod should remain in small flakes but with some presence, not pulverized. At Bacalalo you will find premium quality pieces ideal for this dish.
How long does cod à Bras take to make?
The total time is about 40-45 minutes, including ingredient preparation. The longest step is sautéing the onion, which requires 15-20 minutes over low heat. Frying the potatoes takes another 10-15 minutes. The final pan-frying phase, from adding the cod until serving, takes no more than 8-10 minutes. If you use bagged straw potatoes, you can have the dish ready in 25 minutes.
What wine pairs best with cod à Bras?
The classic pairing is a young, refreshing white Portuguese Vinho Verde, which cuts through the richness of the egg and fried potatoes. Other excellent options include an Alvarinho from Minho, an Albariño from Rías Baixas, or a Godello from Valdeorras. The important thing is that it is a white wine with good acidity and not too much oak, so as not to compete with the delicacy of the dish.
Can cod à Bras be prepared in advance?
It is not recommended to assemble the complete dish in advance, as the egg will overcook and the potatoes will lose their crispiness. What you can do is prepare all the components separately: shredded cod, sautéed onion, fried potatoes, and beaten eggs. When ready to serve, heat the onion with the cod in the pan, add the potatoes, and pour in the egg. It will be ready in five minutes.
Is cod à Bras a healthy dish?
It is a nutritious dish with a good protein profile thanks to the cod and eggs. However, the presence of fried potatoes and olive oil makes it a caloric recipe if quantities are not controlled. To make it healthier, you can bake thinly sliced potatoes with a little cooking spray until crispy, reduce the amount of oil in the sauté, and increase the proportion of cod to potatoes.
Can I add vegetables to cod à Bras?
The original recipe does not include vegetables beyond onion and garlic, but variants with red and green peppers are very popular in Portugal, especially in the Alentejo region. You can also add sautéed wild asparagus or fresh spinach incorporated at the end with the egg. The important thing is that any addition respects the balance of the dish and does not detract from the fundamental trio of cod, potatoes, and egg.
