Pickled cod is one of the oldest and most flavorful recipes in Spanish cuisine. This preservation method, which combines frying with a bath of vinegar, olive oil, vegetables, and spices, transforms desalinated cod into a deep-flavored, aromatic, and addictive dish that improves with each passing day. In this article, we'll teach you the traditional pickled cod recipe step-by-step, with all the tricks to make it perfect. Marc González Sáez, from Barcelona's Mercat del Ninot, shares a recipe he has been preparing since 1990.

What is Escabeche? History and Fundamentals
Escabeche is a culinary technique with over a thousand years of history on the Iberian Peninsula. The word comes from the Arabic sikbāǧ, a sweet and sour stew with vinegar that the Arabs brought to Spain. For centuries, escabeche was much more than a recipe: it was an essential preservation method in an era without refrigerators. Fishermen and cooks discovered that submerging fried fish in an acidic mixture of vinegar, oil, and spices could keep it in good condition for weeks.
The principle is simple and effective: vinegar acidifies the medium, inhibiting bacterial growth. Olive oil creates a protective layer that isolates the food from the air. Spices — bay leaf, pepper, thyme, clove — provide natural antimicrobial compounds as well as extraordinary flavor. The result is a dish that not only preserves but improves over time: flavors meld, vinegar softens, and the cod absorbs all the aromas of the escabeche.
In Spanish tradition, escabeche has been applied to all types of fish — bonito, sardines, mackerel, partridge, quail — but pickled cod holds a special place. Cod, with its firm flesh and ability to absorb flavors, is the perfect canvas for this technique.
Ingredients for Pickled Cod (Serves 4)
For the cod
- 800 g of desalinated cod loins, cut into 5 cm pieces
- Wheat flour for coating
- Extra virgin olive oil for frying (plenty)
For the escabeche
- 200 ml extra virgin olive oil
- 150 ml white wine vinegar (or Sherry vinegar for more complexity)
- 2 medium leeks, cut into 1 cm slices
- 2 large carrots, peeled and thinly sliced
- 12 French shallots (or 2 medium onions, thickly julienned)
- 1 whole head of garlic, cut in half crosswise
- 10 black peppercorns
- 5 sprigs fresh thyme
- 3 bay leaves
- 2 dried chilies (cayenne or spicy ñora)
- 3 cloves
- 1 tablespoon capers
- 1 teaspoon paprika de la Vera (sweet or bittersweet)
- 200 ml dry white wine
- Salt
Preparing the Cod
The success of good pickled cod begins long before you turn on the stove. The cod must be properly desalinated: 48 hours in cold water, changing the water every 8-10 hours, always in the refrigerator. Overly salted cod will ruin the escabeche's balance; overly desalinated cod will be bland.
Once desalinated, thoroughly pat the cod pieces dry with paper towels. This step is crucial: if the cod is damp, it will splatter when frying and you won't get a crispy crust. Lightly flour each piece, shaking off the excess. The flour coating serves a dual purpose: it protects the cod flesh during frying and helps slightly thicken the escabeche liquid.
Heat plenty of olive oil in a wide pan over medium-high heat (about 170-180 °C). Fry the cod pieces on both sides for about 2-3 minutes per side, until golden brown on the outside but juicy on the inside. Do not overcook them: the cod will continue to "cook" in the hot escabeche. Remove and set aside on absorbent paper.
The cod makes all the difference.

The Escabeche Step-by-Step
In a wide, shallow pot (ideally an earthenware pot or cast iron Dutch oven), heat the 200 ml of olive oil over medium heat. Add the whole French shallots (or julienned onion) and let them brown slowly for 5 minutes, stirring occasionally. Add the sliced carrots and leeks. Sauté for another 5 minutes until the vegetables begin to color.
Add the cut head of garlic, peppercorns, cloves, chilies, thyme, and bay leaf. Stir for a minute to release the aromas of the spices. Sprinkle in the paprika de la Vera, stir quickly (paprika burns in seconds), and immediately add the white wine. Let the alcohol evaporate for 2-3 minutes over high heat.
Reduce the heat and add the vinegar. This is the key moment: the classic ratio is 2 parts oil to 1 part vinegar, but you can adjust to your taste. If you prefer a milder escabeche, reduce the vinegar to 100 ml and compensate with more wine. Simmer over low heat for 15-20 minutes, until the vegetables are tender but still have some texture.
Add the capers, stir, and taste the liquid. It should have a balanced flavor between acidic, fatty, and aromatic. Adjust salt if necessary (carefully, as the cod will add some saltiness).
Place the fried cod pieces in the pot, submerging them in the hot escabeche. The liquid should cover at least three-quarters of the fish. If there isn't enough, add a little more oil and vinegar in the same proportion. Simmer everything together over very low heat for 5-8 minutes. Do not stir excessively: the cod can break apart.
Remove from heat and let cool to room temperature with the lid on. This slow cooling is part of the process: the cod absorbs the flavors of the escabeche as the temperature gradually drops.
Vegetables and Spices: The Soul of Escabeche
What distinguishes a mediocre homemade escabeche from an extraordinary one are the vegetables and spices. Each element adds a layer of flavor:
- Leeks: soft sweetness and silky texture. They partially dissolve in the escabeche, adding body to the liquid.
- Carrots: natural sweetness that counteracts the acidity of the vinegar. They also add orange color to the escabeche.
- French shallots: the star ingredient. Whole, they maintain their texture and become small flavor bombs. If you can't find them, use spring onions cut into 3 cm pieces.
- Whole black peppercorns: subtle and warm heat. Much more elegant than ground pepper.
- Fresh thyme: herbal, earthy, with woody notes. It is the classic escabeche herb.
- Bay leaf: balsamic, slightly bitter. Three leaves are enough; more would be excessive.
- Chilies: a touch of heat that awakens the palate. If you don't like spice, omit them or use only one.
- Cloves: intense, pungent, a little goes a long way. Three cloves are perfect for this quantity.
- Capers: acidic, salty, with a bitter note that adds complexity. Add them at the end so they maintain their texture.
- Paprika de la Vera: smoky, earthy, with a deep red color that dyes the entire escabeche.
The combination of these spices creates an aromatic profile that is unmistakably Spanish: warm, spicy, with the acidity of vinegar as the common thread.
Resting and Preservation: When Patience Pays Off
Here's the secret many overlook: pickled cod is good on the first day, but it's spectacular from the second day onwards. During cold resting, the flavors meld magically. The vinegar loses its aggressiveness, the oil absorbs the aromas of the spices, and the cod soaks up the entire mixture.
Once cooled to room temperature, store the escabeche in the refrigerator, covered. The ideal temperature is between 4 and 6 °C. Storage: it keeps perfectly for 7-10 days in the refrigerator, as long as the cod is completely submerged in the escabeche liquid. If any piece remains exposed to air, add a little more oil to cover it.
Before serving, take the escabeche out of the refrigerator about 30 minutes beforehand. Escabeche is traditionally served at room temperature or slightly chilled; never hot. At room temperature, the flavors are much more perceptible than straight from the fridge.
Variations of Pickled Cod
Pickled cod with saffron
Add a generous pinch of saffron to the white wine before incorporating it. Saffron provides a spectacular golden color and a floral, bitter, and earthy flavor that elevates the escabeche to another level. This variation is typical of some areas of Castilla-La Mancha.
Mild pickled cod with orange
Replace part of the vinegar (50 ml) with natural orange juice and add the peel of half an orange (without the white pith). The result is a milder escabeche, with citrus notes that combine wonderfully with cod. Ideal for those who find traditional escabeche too acidic.
Quick skillet escabeche
If you don't have time for resting, you can make an express escabeche: fry the cod, sauté the vegetables in the same pan with the spices, add vinegar and oil, and serve the cod with the vegetables on top. It's not a traditional escabeche — more like cod in an escabeche sauce — but the result is very appetizing and can be prepared in 25 minutes.
Escabeche with Sherry vinegar
Replace the white wine vinegar with Sherry reserve vinegar. Sherry vinegar has a complexity and roundness that white wine cannot match: notes of wood, caramel, dried fruits. The resulting escabeche is darker, deeper, and more elegant. It is the preferred version in fine dining restaurants.
Pairing and Presentation
Pickled cod is a complete dish in itself, but it can be accompanied to turn it into a memorable meal:
- Rustic bread: essential for dipping in the escabeche liquid. Bread with a crunchy crust and dense crumb is the perfect companion.
- Green salad: a mix of bitter leaves (arugula, endive, chicory) dressed only with olive oil complements the acidity of the escabeche without competing.
- Boiled potatoes: cut into thick slices and warm, they are a classic accompaniment in Basque and Castilian cuisine.
- Wine: a cold Albariño or a Godello from Valdeorras. The acidity of the wine harmonizes with that of the escabeche. If you prefer red, a young and fresh Mencía from El Bierzo works very well.
For presentation, serve the cod in an earthenware dish with the vegetables and escabeche liquid. Garnish with a few fresh thyme leaves and lemon slices. The earthenware dish maintains the temperature and adds a rustic touch that matches the character of the dish.

Frequently Asked Questions
How long does pickled cod last in the fridge?
Properly prepared pickled cod lasts between 7 and 10 days in the refrigerator, provided the fish is completely submerged in the escabeche liquid. Vinegar and oil act as natural preservatives. If you notice any piece exposed to air, add more oil to cover it.
Can pickled cod be frozen?
Yes, it can be frozen for 2-3 months, but the texture of the cod will be affected. When defrosted, the flesh loses firmness and the vegetables become softer. If you are going to freeze it, do so in airtight containers with the escabeche liquid covering everything. Defrost slowly in the refrigerator for 24 hours.
What type of vinegar is best for escabeche?
White wine vinegar is classic and works perfectly. If you want to elevate the dish, use Sherry reserve vinegar, which adds more complexity and roundness. Avoid very aggressive vinegars like spirit vinegar or cleaning vinegar. Apple cider vinegar is a milder alternative but takes away the Spanish character of the dish.
Is it necessary to fry the cod before pickling?
Traditionally, yes, and we recommend it. Frying creates a protective crust that keeps the fish juicy during marination, as well as a toasted flavor that enriches the dish. However, there is a lighter version where the cod is poached directly in the hot escabeche without pre-frying. The result is milder and less caloric, but it loses the characteristic texture.
Can escabeche be made with unsalted cod?
It is not recommended. Salted cod has a very high salt concentration that would completely unbalance the escabeche. You should always desalt the cod beforehand (48 hours in cold water, changing every 8-10 hours). If you buy already desalinated cod, you can use it directly.
Is escabeche served cold or hot?
Pickled cod is traditionally served at room temperature or slightly chilled. Never hot: heat alters the balance of flavors created during resting. Take it out of the refrigerator about 30 minutes before serving so it can come to temperature and the flavors can fully express themselves.
Can I reuse the escabeche liquid?
Yes, the escabeche liquid can be reused once more to pickle another batch of cod or other fish. Heat it, adjust the amount of vinegar and oil, and repeat the process. Reused liquid has even more flavor than the original. Do not reuse it more than once for food safety reasons.
Pickled cod is one of those recipes that connects directly with Spain's culinary history. It is a humble dish in its origin — born out of the need to preserve fish — but sophisticated in its result. The key lies in patience: proper desalting, precise frying, a balanced escabeche, and, above all, the resting that allows the flavors to meld. As we say at the Mercat del Ninot: the best recipes are not made with just hands, but with time.
