Bacalhau à Brás

Bacalhau Dourado, Golden Cod with Egg and Potato

Bacalhau à brás recipe: desalted shredded cod, golden matchstick potatoes and softly scrambled egg, finished with black olives and parsley. One serving is about 350 g.

Lisbon tradition credits this dish to Brás, a tavern keeper in the Bairro Alto quarter in the 19th century, who is said to have invented it from leftover salt cod, eggs and potatoes — the humble ingredients every Lisbon kitchen kept on hand. Whether or not the tavern keeper is real, the dish became a fixture of Lisbon's tascas and is now one of the most cooked cod dishes in Portugal, a country that famously claims hundreds of ways to cook bacalhau.

Pairs well with: A simple green salad and a glass of vinho verde

A good bacalhau à brás is judged by contrast: crisp potatoes, creamy just-set egg, and flakes of cod in every forkful.

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 50m
P

Prep Stage: Soak, Shred & Slice

25 Mins • Soak 24 Hours Ahead

Soak the salt cod in cold water for 24 hours, changing the water 3–4 times so the salt draws out evenly. Drain it, remove skin and bones, and shred into fine flakes. Meanwhile cut the potatoes into 3 mm matchsticks, rinse and dry them well, slice the onion, chop the garlic and parsley, and beat the eggs with pepper.

Maestro Tip: Dry potatoes fry crisp; wet ones steam and turn soggy, so towel-dry them properly.

  1. 1

    Soak and Shred the Cod

    24 Hours Soaking + 10 Mins Cold water, ~20°C (68°F)

    Soak 400g of salt cod in cold water for 24 hours, changing the water 3–4 times. Drain, pat dry, pull off the skin, pick out any bones, and shred the flesh into fine flakes with your fingers.

    Taste a flake after soaking: it should be pleasantly salty, not harsh. If it still stings, soak a few hours longer.

    Done when: Flakes are tender, lightly salted, and free of skin and bones.

  2. 2

    Fry the Matchstick Potatoes

    12 Mins Oil at ~175°C (350°F)

    Heat 30 ml of olive oil in a wide frying pan over medium-high heat. Fry the matchstick potatoes in two batches for about 5–6 minutes each, turning once, until pale gold and crisp. Lift out with a slotted spoon and drain on paper.

    Fry in batches — crowding the pan drops the oil temperature and the potatoes go limp instead of crisp.

    Done when: Potatoes are golden, crisp at the edges, and tender inside.

  3. 3

    Soften Onion, Garlic and Cod

    5 Mins Medium heat, ~160°C (320°F)

    In the same pan, warm the remaining 15 ml of oil over medium heat. Soften the sliced onion for 3 minutes until translucent, add the garlic for 30 seconds, then stir in the shredded cod and cook for 2 minutes until it is heated through and fragrant.

    Do not brown the garlic — it turns bitter in seconds, so add it after the onion has softened.

    Done when: Onion is soft and sweet-smelling; cod is hot all the way through.

  4. 4

    Add Potatoes, Then the Eggs

    5 Mins Low heat, ~120°C (250°F)

    Return the fried potatoes to the pan and toss with the cod. Turn the heat to low, pour in the beaten eggs, and stir gently and constantly with a wooden spoon for 2–3 minutes until the egg just sets into soft, creamy curds that coat everything. The residual heat finishes the job — take the pan off the heat while the egg still looks slightly glossy.

    Low heat and constant stirring are the secret: the eggs should bind the dish like a soft scramble, never dry out into rubbery lumps.

    Done when: Eggs are just set and creamy, coating the potatoes and cod; nothing is browned or dry.

  5. 5

    Rest and Serve

    2 Mins Off the heat, ~60°C (140°F)

    Fold in half the chopped parsley, taste and add a pinch of salt only if needed, then plate in a warm dish. Scatter the black olives and the remaining parsley over the top and serve at once.

    Serve immediately — the dish loses its crisp-creamy contrast if it sits.

    Done when: Hot, glossy, and fragrant, with olives and parsley bright on top.

Finishing Touches & Plating

Serve straight from the pan onto warm plates, with black olives and parsley on top. A squeeze of lemon is optional — it lifts the richness of the egg and oil.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.

Vitamins & minerals: Vitamin B12 and selenium (cod), vitamin B6 and potassium (potato), vitamin D and choline (egg), vitamin K (parsley).

High-Quality Protein

Cod and egg together supply about 36 g of complete protein per serving, with all essential amino acids the body needs to build and repair muscle.

Heart-Friendly Fats

Olive oil is rich in monounsaturated fat, and cod contributes omega-3 fatty acids — fats associated with healthier blood lipid profiles when they replace saturated fat.

Potassium and B Vitamins

Potatoes add potassium and vitamin B6, cod adds vitamin B12 and selenium, and parsley brings vitamin K and vitamin C to the plate.

Food Pairings

What to Eat With

To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:

Vegetables

Simple Green Salad

Crisp lettuce with a light lemon-olive oil dressing cuts through the richness of egg and oil and adds fresh crunch.

Drinks

Vinho Verde

A chilled, lightly sparkling vinho verde has the acidity to balance the salty cod and the fat of the egg, and it is the traditional Lisbon pairing.

Sides

Crusty Bread

A slice of crusty bread is ideal for scooping up the soft egg and any golden crumbs left on the plate.

Full Menus

Full Lisbon Menu

Follow with fresh fruit and a small coffee, as in a Lisbon tasca — the fruit's acidity refreshes the palate after the salty, savoury main.

Complete menu

Start with bacalhau à brás as the main, with a simple green salad and crusty bread on the side and a chilled vinho verde; finish with fresh fruit.

Digestive Guardrails

What NOT to Combine

To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:

Extra Salt Before Tasting

Salt cod stays salty even after soaking, and olives add more sodium. Adding salt before tasting easily pushes the dish over-salty; always taste first. This is general information, not medical advice.

Heavy Cream Sauces on the Side

The dish is already rich from egg and oil, so a heavy cream sauce adds saturated fat without improving flavour — a light salad is the better match. This is general information, not medical advice.

General information only, not medical advice — consult a doctor for personal dietary decisions.

Who Should Eat It

Who Should Eat

  • General adultsA complete, satisfying dinner — protein, carbs and healthy fat in one pan.
  • ChildrenSuitable from age 3+; pick out the olives if they dislike them and check carefully for small cod bones.
  • ElderlySoft and easy to chew; keep the portion moderate because of the salt, and use well-soaked cod.
  • Pregnant womenGenerally suitable — the cod is fully cooked and the eggs are set through; keep the portion moderate due to sodium.
  • Breastfeeding womenGenerally suitable; the protein and B12 support recovery — drink water alongside, as the dish is salty.
  • AthletesA strong post-training meal with about 36 g protein per serving plus fast carbs from potato for glycogen.
  • Weight gainA good choice — add an extra egg and a second helping of potatoes, plus bread on the side.
  • Weight lossUse half the oil, fry the potatoes in a non-stick pan with less oil, and fill half the plate with salad.

Health Conditions — Adjust or Avoid

Conditions

  • DiabetesKeep the potato portion to about a third of the plate and add extra salad; the egg and cod themselves are low in carbohydrate. Ask your clinician about portion size.
  • High blood pressureSoak the cod thoroughly, skip the olives and any added salt, and keep the portion modest — most of the sodium comes from the cod. Ask your clinician about portion size.
  • Kidney diseaseThis dish is high in sodium and potassium from cod and potato; eat rarely and in a small portion, and ask your clinician first.
  • GoutEat occasionally and in smaller portions — fish and egg are moderate in purines. Ask your clinician about frequency.
  • Stomach issuesUsually well tolerated, but go easy on the black pepper and fried potato if your stomach is sensitive.
  • Cardiovascular diseaseUse olive oil rather than butter, keep the egg yolks to 4–5 for the batch, and load up on salad. Ask your clinician about portion size.
  • Fatty liverKeep the portion modest, fry with less oil, and favour the cod and egg over extra potato. Ask your clinician about portion size.
  • Food allergiesContains fish (cod) and egg. Naturally gluten-free — just confirm the olives and any stock used are gluten-free if you have coeliac disease.
  • Special therapeutic dietsIf you follow a prescribed low-sodium diet, soak the cod longer and skip the olives; check with your clinician before eating.

If you have a medical condition, consult your doctor before changing your diet.
