Bacalhau à Brás (Portuguese Salt Cod)

Method

1. Prepare the salt cod by soaking it in cold water for 24-48 hours in the refrigerator, changing the water every 8-12 hours. After soaking, place the cod in a saucepan, cover with fresh cold water, and bring to a gentle simmer. Poach for 8-10 minutes until the fish flakes easily. Drain, remove any skin and bones, and shred into thin flakes by hand.

2. Fry the potatoes by heating oil to 350°F. Fry the matchstick potatoes in batches for 3-4 minutes until golden and crispy. Drain on a wire rack. These will soften slightly when mixed with the eggs — that contrast of crispy and soft is the signature texture.

3. Cook the base by heating olive oil in a large skillet over medium heat. Add the sliced onion and cook for 8-10 minutes until soft and golden. Add the garlic and cook 30 seconds. Add the shredded salt cod and toss to combine. Cook for 2-3 minutes to warm through.

4. Add the potatoes and toss gently with the cod and onion mixture. Everything should be evenly distributed.

5. Add the eggs by removing the skillet from heat. Pour the beaten eggs over the mixture and stir gently with a spatula. Return to low heat and stir slowly for 1-2 minutes until the eggs are just barely set — creamy and soft, not dry. The residual heat continues cooking them after you stop.

6. Finish with black olives and a generous shower of fresh parsley. Taste — the cod should provide enough salt, but adjust if needed.

7. Serve immediately on a warm platter. In Portugal, bacalhau à Brás is served family-style with a simple green salad and crusty bread. It's comfort food — unpretentious, satisfying, and deeply flavored.

Equipment

• Large skillet Recommended: Joyce Chen 14-Inch Carbon Steel Wok
• Deep skillet or pot (for frying potatoes) Recommended: Lodge 12-Inch Pre-Seasoned Cast Iron Skillet
• Colander Recommended: OXO Good Grips 5-Quart Stainless Steel Colander

Chef Notes

• The most important thing: Soak the salt cod for 24-48 hours in cold water, changing the water 3-4 times. This removes the excess salt and rehydrates the fish. Under-soaked bacalhau is inedibly salty; properly soaked bacalhau is sweet, flaky, and delicate.
• Shred the cod by hand into thin flakes after soaking and poaching. Don't chop it — hand-shredding follows the natural grain and creates the right texture.
• The potatoes should be cut into thin matchsticks (like shoestring fries) and fried until crispy. They soften slightly when mixed with the eggs, creating a contrast of crispy and soft.
• The eggs should be barely set — creamy and soft-scrambled, not dry. They bind everything together into a cohesive dish. Add them off the heat and stir gently.
• Bacalhau à Brás is one of 365 Portuguese bacalhau recipes — one for every day of the year. Portugal's relationship with salt cod dates back to the 15th century Age of Discovery.

Common Substitutions

Ingredient	Substitution	Notes
Dried salt cod	Fresh cod, seasoned with 1 tsp salt	Skip the soaking — poach fresh cod 8 min, then shred
Matchstick potatoes	Frozen shoestring fries, baked crispy	Quick shortcut — not traditional but works
Black olives	Green olives	Different flavor — both are used in Portuguese cooking
6 eggs	4 eggs + 2 tbsp cream	Richer, creamier result
Olive oil	Butter	Not Portuguese but adds richness

What You're Practicing

Bacalhau teaches you about salt-curing and rehydration — one of the oldest preservation techniques in cooking. Understanding how salt draws out moisture (preservation) and how soaking reverses the process (rehydration) connects you to centuries of culinary history. The same principles apply to salt-cured meats, preserved lemons, and any ingredient that's been dehydrated for storage. Visit Brines, Cures & Marinades for more.

The soft-scrambled egg technique — adding beaten eggs off the heat and stirring gently — teaches you about egg cookery at low temperatures. The same gentle approach produces French-style scrambled eggs, Japanese tamago, and any preparation where you want creamy, custard-like eggs instead of dry, rubbery ones. See Techniques for more.
