Bacalhau à Gomes de Sá
Porto's definitive bacalhau preparation — named for José Luís Gomes de Sá, a 19th-century merchant who created the recipe in the kitchens of the Restaurante Lisbonense in Oporto. Layers of desalted bacalhau, boiled potato, and onion are arranged in an earthenware dish, covered in olive oil, and baked until everything is tender and fragrant. The finishing garnish is hard-boiled egg, black olives, and parsley. Bacalhau à Gomes de Sá is distinguished from other bacalhau bakes by its specific sequence and the technique of soaking the shredded cod in hot milk before layering — this produces exceptional creaminess and removes the last of any excessive salinity.

The Method
1
Place the desalted shredded cod in a bowl. Pour over the hot milk — it must be steaming but not at a rolling boil. Leave to soak for 30–60 minutes. The cod is ready when it feels soft and yielding throughout and carries no sharp saline edge on the tongue.
2
Warm the olive oil in a wide pan over a medium flame. Add the onion rings and cook gently, stirring occasionally, until soft and deep golden throughout — roughly 20–25 minutes. Do not rush this stage; the onion must be fully sweet and collapsed before it can carry the dish.
3
Drain the cod from the milk. In an earthenware baking dish, build the layers in this order: a bed of golden onion, then shredded cod, then sliced potato; repeat — onion, cod, potato — finishing with potato on top. Each layer should be even.
4
Pour olive oil over the entire surface with a generous hand. Every layer must be coated; the surface should glisten and a small pool of oil visible at the base of the dish. Under-oiling is the primary cause of a dry result.
5
Bake uncovered at 200 °C for 25–30 minutes. The dish is done when the top layer of potato is tender to a skewer but still holding its shape, the edges are bubbling, and the kitchen carries a full savour of olive oil and salt cod — not a harsh, dry smell.
6
Remove from the oven. Arrange the sliced or quartered hard-boiled eggs across the surface. Scatter the Portuguese black olives and the chopped parsley. Dust with pimentón if using. Bring the earthenware dish directly to the table.

Quality Hierarchy
01
Reserve — Bacalhau dried and salted from thick-cut Gadus morhua loins; Portuguese single-estate extra-virgin olive oil; Azeitona da Conserva or Galega olives sourced from a specialist importer.
02
Estate — Good-quality salt cod from a Portuguese or Spanish fishmonger; a named Douro or Alentejo extra-virgin olive oil; Portuguese-variety olives from a delicatessen.
03
Market — Salt cod from a reliable supermarket fish counter; a decent supermarket extra-virgin olive oil; the best black olives available in-store — Kalamata is an acceptable fallback.
04
House — Packaged salt cod fillets; standard olive oil; any pitted black olive. The milk soak and the layering sequence must still be observed, or the dish loses its character entirely.

Sensory Tests
◇Taste. After the milk soak, the shredded cod carries no sharp saline edge; it is soft, moist, and balanced.
◇Sight. The sautéed onions are fully collapsed and deep golden — no translucent or white patches remain.
◇Touch. A skewer passes through the potato layers with no resistance, yet the slices hold their form and do not crumble.
◇Sight. The surface of the assembled dish glistens with olive oil and the edges are visibly bubbling in the oven.
◇Smell. At the end of baking, the kitchen carries a full, rounded savour of olive oil and bacalhau — not a harsh or dry note.
◇Where it lives or dies. The milk soak — 30 to 60 minutes in hot milk before layering — is the step that separates a creamy, integrated bacalhau à Gomes de Sá from a dry, sharp-tasting bake.
