Bacalao al Pil Pil: Basque Country’s Iconic Cod Dish
Four simple ingredients produce one of the Basque Country’s most distinctive cod dishes. Bacalao al Pil Pil combines salt cod, olive oil, garlic and chili, with the traditional technique relying on the fish skin and gentle pan movement. Here is how to recognize it, order it and know what to expect.
What should a traveler know before ordering it?
Expect a proper ración or restaurant fish course. Smaller pintxo-size versions exist, but are not the default.
Traditional pil pil uses skin-on cod; the sauce should be silky and emulsified, not a pool of clear oil.
Bilbao is a practical base, but Donostia, Vitoria-Gasteiz and Basque coastal towns also belong to the story.
What Is Bacalao al Pil Pil?
Bacalao al Pil Pil is a traditional Basque preparation of salt cod gently cooked with olive oil, garlic and chili. The ingredient list is short, but the technique is not.
The traditional method uses the cod skin because its natural gelatin helps the olive oil form the characteristic pale-golden, silky pil pil sauce. The cooking is gentle, and the vessel is moved while the oil is incorporated. That skin-and-oil relationship is one of the useful things to understand before ordering it.
That is why the best versions can look deceptively simple: a piece of white cod surrounded by a glossy sauce, with slices of golden garlic and a little chili.
A Dish Built Around Sea, Oil and Technique
Cod has a major place in Spanish cooking, but the Basque Country has its own particularly recognizable cod traditions. Bacalao al Pil Pil is one of the region’s signature preparations, alongside bacalao a la vizcaína.
Basque cuisine is strongly connected to the sea and to high-quality ingredients. Pil pil fits that tradition: very few ingredients, a recognizable local technique, and a dish that lets the cod remain the focus.
If your route already includes Bilbao, pair the old town and its pintxo culture with a proper meal featuring Bacalao al Pil Pil. But do not treat Bilbao as the only place for it: the dish belongs to the wider Basque Country.

Salt cod · olive oil
Garlic · chili
What Does “Pil Pil” Actually Mean?
The word matters because pil pil is not simply “garlic oil.” The characteristic sauce is an emulsion: the natural gelatin from the cod skin combines with olive oil as the cooking vessel is moved gently and continuously.
The skin releases gelatin as the cod cooks gently.
Oil meets the fish juices and gelatin.
Gentle movement helps them combine into the classic sauce.
A proper pil pil should look glossy, silky and connected to the fish — not like plain oil poured over cod.
The Traditional Ingredients
Traditionally desalted before cooking. Skin-on pieces are important to the classic technique.
The main cooking fat and an essential part of the final emulsion.
Usually sliced and gently fried until golden, then used to finish the dish.
A small amount adds aroma and a gentle point of heat rather than dominating the fish.
Spain.info’s traditional recipe for four uses four pieces of cod, 250 ml olive oil, six garlic cloves and one chili pepper. The site classifies it as a second course and gives a medium cost, so think of it as a proper meal.
How Is Bacalao al Pil Pil Cooked?
Soak the salt cod for about 36 hours, changing the water several times.
Gently cook sliced garlic in the oil, then remove it once golden.
Place the cod in the warm oil and cook slowly so the fish stays moist.
Move the cazuela gently while incorporating the warm oil until the sauce emulsifies.
How to Read the Menu Before You Order
This is where Bacalao al Pil Pil becomes more useful as a travel guide than a recipe page. Al pil pil describes the preparation, not a ready-made sauce poured over cod. You are checking whether the dish is being presented in the traditional spirit.
Where Should You Try Bacalao al Pil Pil?
Bilbao
Bilbao is an easy place to connect the dish with the wider Basque food culture. Explore Casco Viejo and its pintxo scene, then choose a proper restaurant meal if you want Bacalao al Pil Pil as the main course.

San Sebastián (Donostia) and Vitoria-Gasteiz also sit within the Basque culinary landscape. If either city is already on your route, there is no reason to detour to Bilbao solely for this dish.

What Should You Expect to Pay?
There is no single Spain-wide price. Recent 2026 menus checked in Bilbao and San Sebastián show Bacalao al Pil Pil examples from roughly €12 to €32 for a portion, with more elaborate or higher-end restaurants potentially above that. Treat this as a working travel range, not a fixed price, and check the current menu before ordering.

Method
