Bonito en Escabeche: Spanish Marinated Tuna Classic 2026

Bonito en escabeche is a traditional Spanish dish that turns fresh tuna into a tangy, aromatic delight. The fish is briefly seared, then simmered with vinegar, paprika, garlic, bay leaves and vegetables, creating a marinade that deepens the flavor over time. It's a technique that dates back to the days before refrigeration, when vinegar was used to preserve food, but today we make it simply because it tastes extraordinary.

This dish is especially popular in northern Spain during tuna season, from summer into early autumn. While the recipe calls for a minimum of 24 hours of marinating, the wait is well worth it—the fish becomes infused with the smoky paprika and sharp vinegar, and the carrots and onions turn sweet and tender. Serve it as a tapa, an appetizer, or a main course, and enjoy the robust flavors of the sea.

Ingredients for Bonito en Escabeche

For 2 servings

• 500 g fresh bonito (1 thick slice)
• Salt
• 50 ml extra virgin olive oil
• 1 or 2 carrots
• 1 onion
• 3 or 4 garlic cloves
• 2 or 3 bay leaves
• 1 teaspoon peppercorns
• 1 teaspoon sweet paprika
• 60 ml white wine vinegar
• 120 ml water

How to Make Bonito en Escabeche Step by Step

1. Clean and cut the bonito

Start by cleaning a thick slice of fresh bonito, about 500 g. Remove the skin and bones. Once clean, cut it into medium pieces, approximately 3 or 4 cm. If desired, you can remove the dark part for aesthetics, but it is completely edible. If you remove it, don't discard it—it can be used for a tuna omelet, pasta dish, salad, or whatever you like.

2. Optional: soak in ice water

If you want to improve the firmness of the fish and eliminate any traces of blood, you can optionally soak the bonito pieces in ice water for 30 minutes.

3. Dry and season the fish

Afterward, dry the fish very well with paper towels or a clean cloth, then season with salt to taste.

4. Sear the bonito on one side

Once the bonito is ready, heat 50 ml of extra virgin olive oil in a wide skillet over medium heat. When the oil is hot but not smoking, place the bonito pieces and sear them on one side for 1 minute. The goal is to lightly brown the outside without fully cooking the inside.

5. Sear the other side and remove

Once the bonito is golden on one side, carefully flip it and sear the other side for a short time as well, so it stays juicy inside. As soon as it's done, remove the bonito from the skillet and set aside.

6. Prepare the vegetables

Now start preparing the base of the escabeche. Peel and cut 1 or 2 carrots into thin slices and 1 onion into julienne strips. Also peel 3 or 4 garlic cloves and cut them in half.

7. Sauté the aromatics

In the same oil, add the carrots, onion, garlic, 2 or 3 bay leaves, and 1 teaspoon of peppercorns. Sauté everything over medium heat for about 10 minutes, stirring occasionally. Once done, season with salt, remove the skillet from the heat, let it cool for half a minute, add 1 teaspoon of sweet paprika, and mix.

8. Return the bonito and add liquids

Place the bonito back in the skillet, on top of the vegetables and spices. Pour 60 ml of white wine vinegar over the bonito, then add twice that amount of water, which is 120 ml.

9. Cook the escabeche

Return the skillet to the heat, this time over medium, and let the liquid come to a gentle boil. When it boils, cook the mixture for 5 minutes over medium-low heat, turning the bonito halfway through so it cooks evenly on both sides.

10. Cool and marinate

After those 5 minutes of cooking, remove the skillet from the heat and let it cool. Then transfer the contents to an airtight container. Cover well and store in the refrigerator for at least 24 hours before consuming, so the escabeche macerates and gains flavor.

Tips for the Best Bonito en Escabeche

Customize the spices

We use bay leaf, garlic, pepper, and paprika, but you can also use other spices like thyme or rosemary and remove any you don't like. Feel free to adjust the spice blend to your taste.

Adjust the vegetables

We've added plenty of carrot and onion because we like it generous, but you can try removing some or adding others like leek, for example. The escabeche is versatile, so make it your own.

Be patient with the marinating time

The hardest part of preparing this dish is waiting for the necessary resting time before you can enjoy it. A minimum of 24 hours in the refrigerator allows the flavors to meld and the fish to absorb the marinade. After that, you can eat it as is, as an appetizer, main course, or even as an ingredient in other dishes like rice or salad.
