Bacalhau à Brás is one of Lisbon’s most beloved cod dishes, combining tender salted fish with crisp potato matchsticks, onion, softly set eggs, olives, and parsley.
Desalted cod is gently warmed with onions before the potatoes and eggs are folded through. The goal is a creamy skillet texture with plenty of golden potato strands.

Desalt the cod in the refrigerator, changing the water several times. Taste before adding salt because the fish may still carry plenty of seasoning.
Serving Suggestions
Serve immediately with a green salad, lemon wedges, and extra black olives. A light Portuguese white wine pairs well.

Recipe Notes
The cod can be desalted a day ahead. Bacalhau à Brás is best fresh because the potatoes soften as it stands.

- Large bowl
- Fine strainer

Ingredients
Cod and Potatoes
- 1 lb salted cod desalted, skinless, and boneless
- 1/4 cup olive oil
- 1 medium yellow onion thinly sliced
- 2 cloves garlic minced
- 1 lb russet potatoes cut into matchsticks
- 6 large eggs lightly beaten

Instructions
Prepare the Cod and Potatoes:
- Soak the cod in cold water in the refrigerator for 12 to 24 hours, changing the water several times. Drain, simmer in fresh water for 8 minutes, cool, and flake.
- Fry the potato matchsticks in batches until pale golden and crisp. Drain well.
Cook the Brás:
- Warm the olive oil in a large skillet. Cook the onion and garlic until soft and translucent, about 6 minutes.
- Fold in the flaked cod and cook for 2 minutes. Add the potatoes and toss gently.
Add Eggs and Serve:
- Lower the heat and pour in the beaten eggs. Stir gently until just set and still creamy.
- Fold in the olives and parsley. Serve immediately with lemon wedges.
Notes
- Desalting time depends on the thickness of the cod.
- Keep the egg softly set rather than fully dry.
- Add salt only after tasting the cod mixture.
