Golden Cod: Traditional Portuguese Recipe Step by Step
Golden cod — known in Portugal as Bacalhau à Brás — is probably the most emblematic cod recipe in Portuguese gastronomy. A dish that combines shredded cod, straw potatoes, scrambled eggs, and black olives in a seemingly simple mixture that demands mastery of timing and textures. This guide details the complete process, including common mistakes that ruin the dish and tricks that elevate it.

What is Golden Cod
Golden cod is a Portuguese dish that combines shredded desalted cod with very thinly julienned potatoes (straw potatoes), sautéed onion, scrambled eggs, black olives, and parsley. The result is a creamy, lightly golden mixture with a contrast of textures ranging from the crispness of the potato to the softness of the egg.
In Portugal, it is known as Bacalhau à Brás — named after the Bica neighborhood in Lisbon where it was supposedly invented — and it is one of the 365 cod dishes that the Portuguese boast of having, one for each day of the year. It's no exaggeration: Portugal consumes more cod per capita than any other country in the world, and this recipe is its most recognizable ambassador.
What makes this dish special is not the ingredients — all of them are pantry staples — but the technique. The egg must be creamy, never set like an omelet. The potatoes must retain some crispness. And the cod must be shredded into fine fibers, integrated but identifiable. When everything comes together, the result is addictive.
Origin and History of Bacalhau à Brás
The history of Bacalhau à Brás is linked to the taverns of 19th-century Lisbon. According to the most widespread version, the dish was created by a tavern owner in the Bica neighborhood named Brás who sought to use leftover cod. Another theory attributes the recipe to a merchant named Brás from the Madalena neighborhood.
What is certain is that the dish originated as popular and economical food. Dried salted cod was — and still is — the omnipresent ingredient in the Portuguese pantry. Potatoes, onions, and eggs were available all year round. The combination was logical, accessible, and satisfying.
Over time, Bacalhau à Brás moved from taverns to Portugal's most prestigious restaurants. Today it is featured on the menus of Michelin-starred establishments, although its essence remains the same: a dish made from leftovers elevated to the status of a gastronomic icon. In Spain, the recipe has become popular as "bacalao dorado" (golden cod) and is one of the most sought-after preparations by those who appreciate quality cod.

Step-by-Step Recipe
Step 1: Prepare the cod (10 minutes)
If using ready-to-use desalted cod, simply remove any remaining bones or skin. Shred the cod by hand into fine fibers, following the natural grain of the muscle. Do not use a knife: irregular fibers integrate better with the egg and potato. Set aside in a bowl.
If starting with dried salted cod, you need to properly desalt it for 48 hours before starting. This is the most important step in the entire recipe.
Step 2: Fry the potatoes (15 minutes)
Cut the potatoes into very thin julienne — ideally 2-3 mm thick. If you have a mandoline, use it. If not, be patient with the knife. Dry them thoroughly with a clean cloth: moisture is the enemy of frying.
Heat plenty of olive oil (or sunflower oil for frying) to 180 °C (350 °F). Fry the potatoes in small batches until golden and crispy, about 3-4 minutes per batch. Drain them on paper towels. Set aside. The potatoes should be slightly crispier than you want them in the final dish, as they will soften when mixed with the egg.
Step 3: Sauté the onion and garlic (10 minutes)
In a large skillet (or shallow pot), heat 80 ml of extra virgin olive oil over medium-low heat. Add the julienned onion and sauté for 8-10 minutes, stirring occasionally, until completely translucent and sweet. Do not brown it: we want softness, not caramelization.
Add the chopped garlic in the last 2 minutes. Stir to prevent it from burning.
Step 4: Incorporate the cod (3 minutes)
Increase the heat to medium. Add the shredded cod to the skillet with the onion. Stir for 2-3 minutes so that the cod absorbs the flavors of the sofrito and heats through. Cod does not need long cooking: it is already cooked (or cold-desalted). It just needs to integrate.
Step 5: Add the potatoes (1 minute)
Add the fried straw potatoes to the skillet. Mix carefully to avoid breaking them too much. We want them to retain some structure and texture.
Step 6: The eggs — the critical step (2-3 minutes)
Beat the 6 eggs in a bowl with a fork. Do not overbeat them: we want to see some streaks of white and yolk, not a homogeneous mixture.
Lower the heat to minimum. Pour the beaten eggs over the cod and potato mixture. Stir immediately with a wooden spatula, using folding motions, for 2-3 minutes. The goal is for the egg to partially set, creating a creamy texture that binds all the ingredients. The point is when the egg is no longer liquid but still shiny and juicy.
Fatal error: leaving the heat high. If the eggs set completely, you will have a shredded omelet, not golden cod. Remove from heat even a little earlier than you think necessary — residual heat will continue to set the egg on the plate.
Step 7: Serve (immediately)
Serve immediately on warm plates. Garnish with black olives and chopped fresh parsley. Optionally, add a few flakes of Maldon salt on top. Golden cod does not wait: it is eaten right away.
Tips for Perfect Texture
- Room temperature eggs: if you take them out of the fridge cold, they will cool the mixture and take longer to set, which can result in soft potatoes.
- Well-dried potatoes before frying: moisture causes splattering and prevents them from browning properly.
- Don't skimp on oil: golden cod is not a diet dish. Olive oil is part of the recipe, not a dispensable cooking medium.
- Shred by hand, never by machine: irregular fibers integrate better and maintain their identity in the dish.
- Minimum heat for the egg: this is the difference between a creamy texture and a dry disaster.
- Serve on a warm plate: prevents the egg from continuing to set due to thermal changes.
Common Mistakes That Ruin Golden Cod
| Error | Consequence | Solution |
|---|---|---|
| Poorly desalted cod | Salty dish or rubbery texture | Desalt for 48h with 3 daily water changes |
| Eggs over high heat | Broken omelet texture, dry | Minimum heat, remove early |
| Thick potatoes | Don't integrate, end up like french fries with cod | Julienne 2-3 mm max |
| Raw or burnt onion | Aggressive or bitter taste | Sauté 10 min over medium-low heat |
| Adding salt without tasting | Inedible dish | Always taste: cod already adds salt |
| Serving cold or reheated | Set egg, soft potatoes | Serve immediately on a warm plate |
Variations and Adaptations
Golden cod with cream
Some Portuguese versions add 2-3 tablespoons of liquid cream to the beaten eggs. The result is creamier but heavier. It works well in winter.
Baked golden cod
An adaptation for serving many diners: prepare the mixture up to step 5 (without eggs), place it in a baking dish, pour the beaten eggs over it, and gratinate at 200 °C (390 °F) for 8-10 minutes until the egg sets. You lose some creaminess but gain convenience. You can see more baked cod recipes for inspiration.
Version with commercial potato chips
The emergency trick no one admits to: substituting homemade straw potatoes with thin bagged potato chips. The result is not the same, but for an impromptu dinner, it works surprisingly well.
Golden cod with red pepper
Adding finely sliced red pepper to the sofrito adds color and a touch of sweetness. It's a popular variation in the Algarve.
Nutritional Value
Golden cod is a complete dish from a nutritional point of view. Per serving (approximately 350 g):
| Nutrient | Amount per serving | % Daily Value |
|---|---|---|
| Calories | 480-520 kcal | 24% |
| Protein | 32-36 g | 64% |
| Total Fat | 28-32 g | 40% |

| Omega 3 | 0.8-1.2 g | 50% |
| Vitamin B12 | 4.5 µg | 188% |
| Selenium | 45 µg | 82% |
Most of the fat comes from olive oil and eggs — both sources of quality fat. Cod provides lean protein of high biological value. It is not a light dish, but it is nutritionally balanced.
Wine Pairing: What Wine to Serve
Golden cod pairs well with full-bodied white wines. Verified options:
- Vinho Verde: the natural Portuguese option. Fresh, slightly effervescent, cuts through the richness of the dish.
- Albariño: for those who prefer a Spanish white. The acidity and citrus aromas complement the cod.
- Godello: fuller-bodied than Albariño. Works especially well if you add cream to the recipe.
- Verdejo: a good economical option, with herbaceous notes that balance the richness of the dish.

Frequently Asked Questions
Can I make golden cod with frozen cod?
Yes, but the result will be different. Frozen cod has more water and less fibrous texture than desalted dried cod. If you use it, thaw it completely in the refrigerator, drain it well, and dry it with paper towels before shredding. The version with desalted cod is superior in taste and texture.
How long does it take to make golden cod?
If you start with already desalted cod, the active preparation time is 35-40 minutes: 15 minutes for frying potatoes, 10 minutes for the onion sofrito, 3 minutes for the cod, and 2-3 minutes for the eggs. If you need to desalt the cod, add 48 hours beforehand.
Can golden cod be reheated?
It is not recommended. The egg sets more when reheated, and the potatoes lose all their texture. If you have leftovers, the best option is to eat it at room temperature as a tapa. If you insist on reheating it, do so over very low heat in a skillet, adding a drizzle of olive oil and an extra beaten egg to restore creaminess.
What is the difference between golden cod and Bacalhau à Brás?
They are the same dish. Golden cod is the common name in Spain; Bacalhau à Brás is the original Portuguese name. Some Portuguese versions are slightly more generous with oil and have the onion sautéed longer, but the basic technique is identical.
Can I use bagged straw potatoes?
You can, and the result is acceptable for a quick dinner. However, bagged straw potatoes are thinner and soften faster when they come into contact with the egg. The ideal is fresh potatoes cut into julienne and fried at the moment.
How many eggs does golden cod have per person?
The classic ratio is 1.5 eggs per person: for 4 people, 6 eggs. Some more generous recipes use up to 2 eggs per person. With less than 1 egg per person, the mixture will be dry and lack the characteristic creaminess.
Which part of the cod is best for this dish?
Loin and center are the best options: they have long fibers, few bones, and a thickness that facilitates shredding. Cod flakes also work well and are more economical. Tails and scraps are too thin and fall apart too much.

The flakes are cuts of desalted cod: same product, same flavor, more accessible price. They are already shredded, saving you a step. Ideal for recipes where cod integrates with other ingredients.
Conclusion
Golden cod is one of those recipes that demonstrate that product-based cuisine doesn't need to be complicated. Well-desalted cod, thin potatoes, patiently cooked onion, eggs with technique. Nothing more. The secret lies in respecting the timing — especially for the egg, which turns a mediocre scramble into a memorable dish.
If you use quality cod, the result is noticeable in every bite. There's a difference between shredding long, firm fibers from North Atlantic cod and working with frozen cod that disintegrates in water. The raw material dictates the outcome.
