Traditional Vicenza Style Stockfish from Sandrigo | Baccalà alla Vicentina Tradizionale di Sandrigo
This is the recipe as Sandrigo defends it: the codified version written down by the Venerabile Confraternita del Bacalà alla Vicentina, with soft yellow polenta beside it and nothing on top. No lemon, no tomato, no potato, no cream. Stockfish, white onions, anchovies, parsley, Parmigiano, flour, milk and olive oil, and five hours in which the casserole is not stirred once.
The confraternity exists because the dish was drifting. By the 1980s every restaurant in the province had taken its own liberties, and a group of Sandrigo cooks fixed a reference text before the original disappeared into variations. What they wrote down is short and unusually strict, and most of it concerns what you are not allowed to do.
Cooked this way the fish does not taste of fish the way a fresh fillet does. Air drying concentrates it into something deeper and slightly sweet, and five hours under milk and oil turns the casserole into one pale sauce that clings to the polenta. It is among the very few Italian dishes genuinely better on the second day, and Sandrigo will tell you so before you ask.
Yield: 6 servings. Soaking: 48 to 72 hours. Prep: 40 minutes. Cook: 5 hours for the fish, 45 minutes for the polenta. Rest: overnight, ideally. Difficulty: advanced. Course: secondo piatto with polenta. Region: Veneto, Sandrigo and the province of Vicenza.
The Story
The dish begins with a shipwreck. In the winter of 1431 the Venetian merchant Pietro Querini lost his ship in the North Atlantic and was cast ashore on Røst, in the Lofoten islands, where the islanders kept him alive for months. What struck him was the fish they ate: cod split and hung on wooden racks in the cold wind until it was hard as board and would keep for years. He carried some back to Venice, and with it the trade that made dried cod a fixture of the Veneto table.
Vicenza made more of it than anywhere else. The Council of Trent had multiplied the days on which meat was forbidden, and an inland province with no fresh fish needed something for all of them. Stockfish travelled and stored, and the Vicentine kitchen buried its austerity under onions, milk, cheese and a great deal of olive oil. The result is a Lenten dish that is anything but penitential.
Sandrigo, a village of a few thousand people north of Vicenza, became the guardian of it. The Venerabile Confraternita del Bacalà alla Vicentina was founded there in 1987, published the official recipe, and holds a festa every September where the dish is cooked in quantity and eaten in the open air. The confraternity is partly ceremonial and entirely serious: it exists to say the dish has a fixed form, and that a version with tomato in it is a different dish with a borrowed name.

Preparation
Soak the stockfish
If the fish was not beaten at the shop, beat it with a mallet until the fibres loosen. Stand it in cold water in the refrigerator for 48 to 72 hours, changing the water every 8 hours. Sandrigo cooks traditionally leave it under a slow trickle of running water instead. It is ready when the thickest part yields to a thumb with no woody core left.
Bone the fish and keep the skin
Drain and dry the fish. Split it along the backbone, remove the spine and take out the pin bones with tweezers. The skin stays on every piece: it is the main source of the gelatin that thickens the sauce and it keeps the flesh whole. Cut into pieces of roughly 2 1/2 inches (6 cm), all of similar thickness.
Sweat the white onions
Put the sliced onions in a pan with a third of the olive oil over the lowest heat and cook them about 40 minutes without letting them colour at any point. The Vicentine proportion is half the dry weight of the fish in onions, which sounds excessive until you taste the sauce and realise the onion has become the body of it. Stop when the slices fall apart under a spoon.
Make the anchovy and parsley battuto
Rinse the salted anchovies under cold water, open them out and lift away the bones. Chop them roughly with the parsley, add the mixture to the warm onions and work it over low heat until the anchovy melts entirely into the oil, 3 to 4 minutes. Taste it: there should be salt and savour but no recognisable anchovy flavour left.
Flour the fish and build the layers
Roll each piece in flour and tap off the excess. Choose a casserole that holds the fish snugly in one layer or at most two, since a wide pan spreads the liquid thin and it evaporates before the fish is ready. Spread onion across the base, lay the fish skin side down, season, cover with Parmigiano, then the remaining onion and the rest of the cheese.
Bring the liquid level with the fish
Pour the milk in against the wall of the pan, then the remaining olive oil the same way, until it stands level with the top of the fish and no higher. Too much liquid and five hours will not reduce it; too little and the top layer dries out and turns stringy long before the bottom is done.
Cook five hours without stirring
Set the casserole on a flame diffuser over the lowest possible heat and leave it 4 1/2 to 5 hours, uncovered or barely covered. The surface should move only every few seconds. Nothing goes into the pan and nothing is stirred. If the liquid needs to move, hold the pan by both handles and turn it in a slow circle, which the Vicentini call far pipare and treat as the only permitted intervention.
Stir the polenta
Forty five minutes before service bring the water to a boil with the coarse salt and rain in the maize flour while whisking. When it thickens change to a wooden spoon and stir steadily for 40 to 45 minutes over low heat, scraping the bottom and sides. Vicentine polenta for this dish is soft, loose enough to spread with a spoon, because it has to take a wet sauce.
Rest, and preferably wait a day
The dish is finished when the sauce is thick and ivory and a layer of oil has risen. Let it stand off the heat 20 minutes before serving. Better still, cool it, refrigerate it overnight and rewarm it the next day over the lowest heat: Sandrigo will tell you the second day is the real one.
Plating
Serve it in wide shallow bowls warmed to around 140°F (60°C). The sauce is mostly olive oil and milk fat and sets on a cold plate within a minute, which is why the trattorie of the province warm their plates for this dish and almost nothing else.
Spoon soft polenta onto one side of the bowl rather than the centre, letting it settle into a loose pool. Lift two pieces of fish out with a slotted spatula and set them against the polenta so the sauce runs between them. Spoon plenty of sauce over the fish, including the oil separated on top, which carries most of the aroma and should never be skimmed away.
Nothing else goes on the plate. A turn of black pepper and a few drops of raw olive oil are the limit, and even those are optional. No parsley scattered over the top, no lemon wedge, no garnish. Here restraint is not a style choice but the recipe itself.
Professional Technique
The decisive technique here is the soak, and it is chemistry rather than patience. Air drying removes about 80 percent of the water from the cod and leaves the muscle proteins packed tight against each other. Cold water reverses that slowly, from the surface inwards, and the fibres regain their ability to hold water only if given enough time at a low temperature. Warm water speeds nothing up and starts spoilage, and a short soak leaves a dense core that five hours of gentle heat cannot open, because the casserole never exceeds about 185°F (85°C).
The second is the geometry of the pan, which the confraternity treats as part of the recipe. A narrow deep casserole holding the fish in one or two close layers keeps the liquid column tall, so the lower pieces stay submerged while the surface reduces and the milk concentrates instead of vanishing. The same quantity in a wide pan loses its liquid in two hours and bakes rather than stews. Pan choice is why one ingredient list gives two different results in two kitchens.
The third is the flour. The dusting on each piece is not a coating and never crisps; it dissolves into the liquid and supplies the starch that stabilises an emulsion of milk, olive oil and fish gelatin which would otherwise break under five hours of heat. It is also why stirring is forbidden: starch and gelatin build a fragile structure around each motionless piece, and a spoon destroys it.
Texture and Moisture Control
The finished fish should hold its shape on the spoon and then give way completely in the mouth, with no fibrous pull. That result is set long before the casserole goes on the heat: a properly soaked piece has regained most of its water and softens further, while an under soaked one tightens and stays chewy however long it cooks.
The sauce is the second control point and can only be judged at the end. It should coat a spoon thickly and hold a line drawn through it. If it is still loose at four and a half hours, continue uncovered for 30 more minutes; raising the heat instead curdles the milk proteins and releases the oil as a separate slick. If it has gone too far and looks oily, a tablespoon of warm milk trickled down the side of the pan, with no stirring, brings it back.
The polenta has to stay wet. Vicentine polenta for baccalà is softer than the firm block served with meat, because it has to accept a liquid sauce rather than sit beside one. Hold it covered over the barest heat and beat in hot water if it sets. Serve both at around 160°F (70°C): the sauce turns waxy below that, and the polenta forms a skin.
Professional Mise en Place
Almost everything here happens days in advance and unattended. The only work close to service is the polenta and the plating.
Equipment and tools
Deep container for the soak, and a mallet if the fish is not pre beaten
Narrow heavy casserole, ideally terracotta or enamelled cast iron
Flame diffuser, not optional on gas
Heavy pan for the polenta, whisk and long wooden spoon
Slotted fish spatula and fine tweezers
Prepared ahead
Stockfish soaked with the water changed on schedule, 48 to 72 hours ahead
Fish boned and cut, up to 12 hours ahead, covered and cold
Onions sweated with the anchovy and parsley battuto, up to 1 day ahead
The whole dish cooked the day before and rewarmed, which is the traditional way
Service setup
Casserole warming through very slowly, never simmering
Polenta soft and covered over the lowest heat, hot water within reach
Bowls warming at around 140°F (60°C)
Slotted spatula and sauce ladle ready, pepper mill and oil on the pass
Chef Tips
Weigh the fish dry, before soaking, and work from that number. Stockfish roughly triples in weight during the soak, so a recipe written for 2 1/4 lb (1 kg) of dry fish feeds six from what looks like 6 lb of wet fish on the board. Every proportion here is calculated on the dry weight.
Avoid anchovies in oil if you can. Salted anchovies dissolve cleanly into the onions and leave savour behind, while the oil packed kind carry their own flavoured oil into the pan and stay recognisable as anchovy in the finished sauce.
Cook it the day before. This is not a convenience suggestion but the traditional instruction, and the dish genuinely changes overnight. Rewarming has to be slower than the original cooking, with a spoonful of milk if the sauce has set very firm.
For a crowd, use two narrow casseroles rather than one wide one. Doubling the recipe into a big roasting pan changes the liquid depth and the evaporation rate and gives a dry separated result that no adjustment will save.
Common Mistakes
Using salt cod. The dish is named baccalà but made with stoccafisso, cod dried in air rather than preserved in salt. Salt cod flakes apart within two hours and gives salt instead of gelatin, so the sauce never reaches the right body.
Adding tomato, garlic or cream. None of the three appears in the confraternity recipe and each pushes the dish somewhere else. Tomato turns it into a generic braise and is the commonest error outside the province.
Using a pan that is too wide. Spread thin, the liquid evaporates hours before the fish is ready and the top layer dries into strings. Choose a casserole that holds the fish snugly in one or two layers.
Stirring during cooking. It breaks the starch and gelatin structure forming around each piece and shreds the flesh at the same time. Rotate the whole pan instead.
Cutting the soak short. Two days is the minimum and three is safer for thick loins. A core that has not rehydrated is still chewy after five hours, and nothing corrects it once cooking has started.
Serving it with firm polenta. A set block sheds the sauce instead of taking it. Vicentine polenta for baccalà is soft, loose enough to spread with the back of a spoon.
Wine Pairing
Soave Superiore DOCG: The classic answer and the one poured in Vicenza itself, from the hills a short drive east. Garganega gives quiet stone fruit and a distinct bitter almond finish, and that bitterness keeps the palate from being coated by the oil. Superiore bottlings have enough extract to meet a sauce this rich without needing oak.
Verdicchio di Matelica DOC: From an inland valley in the Marche, and more incisive than its coastal cousin. High acidity and a saline, almost briny thread cut cleanly through the milk fat, while the fennel and citrus aromatics lift the sweetness the onions bring. A wine with real length, which matters against a dish that lingers on the palate.
Ribolla Gialla Collio DOC: A Friulian white with firm structure and a slightly grippy, almost tannic texture for a white, which gives it something to push against the Parmigiano folded between the layers. Its green apple acidity handles the anchovy salt, and the faint herbal note on the finish keeps the whole plate from turning heavy.
Franciacorta DOCG: The Lombard sparkling wine, and the best choice where the dish is served in quantity. The bubble and acidity strip the olive oil coating between mouthfuls, while the bread and hazelnut character from lees ageing runs alongside the cheese and flour in the sauce. Choose a Brut, not a Satin.
Bardolino DOC: The light red of the eastern shore of Garda, for anyone who will not drink white with dinner. Pale, low in tannin and built on sour cherry, it works because it asks nothing of the dish: at around 55°F (13°C) it refreshes instead of competing with a delicate white fish sauce, which a fuller red would flatten.
Storage & Reheating
Keep the fish under its sauce in a shallow airtight container in the refrigerator for up to 4 days. The sauce is the seal, so never lift the pieces out to store them separately. The polenta keeps 3 days covered and will set into a firm block, which is expected and useful.
Rewarm very slowly in a covered pan on a diffuser for 20 to 25 minutes, adding a tablespoon of milk down the side if the sauce has set hard. Do not stir, do not let it simmer, and never use a microwave, which boils the sauce in patches and splits the emulsion permanently. Soft polenta comes back with hot water beaten in over low heat; the set block is better sliced thick and grilled, which is what Veneto households do with it the next day.
The cooked dish freezes for up to 2 months with its sauce, though the texture loosens. Thaw it overnight in the refrigerator and rewarm as above. Do not freeze polenta, which becomes grainy, and never refreeze rehydrated stockfish.
