What to Eat in Bilbao: The City Where Bacalao Is a Philosophy

1. Why Bilbao's food identity is not just pintxos

The standard advice for eating in Bilbao begins and ends with pintxos — the small bites that line bar counters across the Basque Country. Pintxos are worth eating here and this guide covers where to find the best ones. But reducing Bilbao's food culture to pintxos misses what is specific to this city rather than generic to the Basque region.

Bilbao's kitchen is bacalao. Salt cod arrived here through the Basque fishing fleets that crossed to Newfoundland for cod from the 15th century onward, salted the catch on the Newfoundland shore, and brought it back as the dense, shelf-stable ingredient that fed the interior long before refrigeration. Bilbao, as the commercial capital of Bizkaia province, became the regional trading center for dried salt cod, and over centuries two distinct preparations emerged that carry the stamp of this city: bacalao al pil-pil, a sauce made only from the cod's own gelatin and olive oil, and bacalao a la vizcaina, a red sauce built from dried choricero peppers grown in the Basque interior. Both require patience and technique. Both are harder to replicate well outside the Basque Country than any pintxo. Finding a version of either made by a cook who has been doing it for 30 years is what a food trip to Bilbao is actually for.

2. Bacalao al Pil-Pil — the technique, the origin, where to eat it

Bacalao al pil-pil is a sauce made from four ingredients — salt cod, olive oil, garlic, and dried chili — but the technique transforms them into something resembling a thick cream emulsion. The desalted cod is placed skin-side up in a terracotta cazuela covered in warm olive oil with a few garlic slices and a dried guindilla pepper. The pan is then moved in slow, continuous circles over the lowest possible heat. Over 25 to 35 minutes, the gelatin from the cod's skin gradually emulsifies the oil into a thick, ivory-white sauce without any flour, egg, or other binder. The result coats the fish in something dense and glossy that has no equivalent anywhere else in Spanish cooking.

The dish's center of gravity is Bilbao. The legend attributes its discovery to a 19th-century bacalao merchant who found the emulsification process by accident during a gale; the more accurate version is that generations of Bilbao cooks working with the same ingredient, the same cazuelas, and the same Basque olive oil arrived at the same technique through repetition. Several restaurants in the Casco Viejo have been making it since before their current head cooks were born.

Restaurante Gure Toki at Plaza Nueva 12 is the most accessible starting point — a bar and restaurant in the colonnaded square with a consistently reliable pil-pil served without reservation at the bar counter. El Perro Chico at Calle Arbolantegi 2 uses hand-line-caught bacalao from a Getaria supplier; it costs more (€18 for a lunch portion) and requires a reservation, but the quality gap is real. For a version that prioritizes technique over setting, Restaurante Victor at Plaza Nueva 2 has operated since 1942 and the pil-pil is made from a recipe that has never been written down because the same hands have been making it at midday, every weekday, for decades.

3. Bacalao a la Vizcaina — the other signature of Bizkaia

Bacalao a la vizcaina uses the same dried salt cod but submerges it in a dark red sauce built from choricero peppers — a dried sweet pepper cultivated in the Basque interior since the 17th century and grown almost nowhere else. Making the sauce requires soaking the dried peppers overnight, scraping the flesh from the skin, slow-cooking it with onion and garlic until the onion nearly dissolves, then pressing the mixture through a sieve to remove all fiber. The result is a dense, garnet-colored paste that is slightly bitter at the edges and sweet at the center, with a smokiness that comes from the drying process rather than any added spice.

The sauce is specific to Bizkaia province in a way that makes it impossible to compare to anything outside the region. It contains no tomato and no paprika — the deep red color comes entirely from choricero pepper flesh. In autumn, choricero peppers hang in strings from the beams of traditional shops in the Casco Viejo and appear at the Mercado de la Ribera stalls for €3 to €5 per string of eight. The sauce keeps for several days refrigerated and doubles as a base for marmitako and a condiment for bread.

Casa Rufo at Calle Hurtado de Amezaga 5 in the Ensanche is widely considered to serve Bilbao's best vizcaina, in a dining room that has not been renovated since the 1980s. Book ahead for lunch — the dining room is small and fills with a local business crowd on weekdays.

4. The pintxos circuit — Somera, Ledesma, and what to order

Bilbao's pintxos scene differs from San Sebastian's culture of hot, made-to-order preparations in one structural way: Bilbao bars specialize primarily in cold counter work — elaborate assembled bites that showcase ingredient quality and knife technique rather than last-minute heat. You scan the counter and pick what looks freshest rather than watching what is being cooked. For the full history of how the Basque pintxos tradition developed across the region, that post covers the cultural backstory.

Counters reload twice daily: 12:30 PM for lunch and 7:30 PM for the evening txikiteo. Arriving within 20 minutes of either reload gives the best selection. The rhythm is one txikito (small glass of txakoli or txipirones-friendly red) and 2 to 3 pintxos per bar, standing, then moving. A full evening circuit across five or six bars runs €20 to €30 per person all in.

5. Mercado de la Ribera — the fish market and what to find there

The Mercado de la Ribera at Erribera Kalea 22 is the working center of Bilbao's food supply — a 1929 Art Deco building with a stained-glass riverfront facade that Guinness has listed as Europe's largest covered food market by floor area. The ground floor is the professional fish market, where restaurant buyers arrive from 6 AM on market days (Tuesday through Saturday) to purchase from wholesalers who received the overnight catch from Bermeo, Ondarroa, and Lekeitio on the Basque coast.

By mid-morning the market opens to the general public. What is available on any given day depends entirely on what the boats brought in — there is no fixed inventory. September and October are prime months for bonito del norte (white albacore tuna, the base for marmitako), merluza (hake, the single most important fish in Basque cuisine), and the autumn run of kokotxas — cod cheeks, a gelatinous cut from the jaw of Atlantic cod that Bilbao cooks prepare both al pil-pil and in salsa verde.

The upper floor food court serves coffee and simple preparations from 8 AM: tortilla made from eggs collected that morning, montaditos, and fresh-pressed juice. The cheese section on the same level stocks Idiazabal from several producers. It is a working market rather than a curated food hall, which keeps prices low and the clientele genuinely local through the morning.

6. Kokotxas, txipirones, and the autumn catch from the Nervion

Two preparations beyond bacalao and pintxos define Bilbao's autumn table and are worth knowing before you arrive.

Kokotxas — the gelatinous triangular cheek cut from the jaw of Atlantic cod or hake — are among the most prized ingredients in Basque cooking for the same reason pil-pil works: the collagen content is high enough that the cut nearly emulsifies itself in cooking fat without any added thickener. Kokotxas al pil-pil is a smaller, more intense version of the full bacalao preparation. Kokotxas en salsa verde uses a parsley-and-garlic sauce with white wine and clam juice — brighter in color and flavor, slightly lighter in texture. Both appear on autumn menus in Bilbao when the boats are bringing in larger Atlantic cod. Bar Restaurante Berton at Calle Jardines 11 serves both as pintxo-sized bar portions, which lets you compare them without committing to a full sit-down order.

Txipirones en su tinta — small whole squid cooked in their own ink with onion and a little tomato — is the preparation that most clearly distinguishes Basque coastal cooking from other Spanish seafood traditions. The ink sauce is dense, slightly briny, and nearly black; the tender squid body and intensely savory ink is a combination that appears in other Spanish regions but nowhere with the same consistency of execution as in Bilbao. Serve on white bread to absorb the sauce. Bar Ledesma's version on Calle Ledesma 8 is the city's most reliably excellent.

7. FAQ: What does eating in Bilbao cost in 2026?

Bilbao is meaningfully less expensive than San Sebastian and Barcelona for equivalent quality, and roughly comparable to Madrid for traditional food at the bar level.

8. FAQ: Is October a good time to eat in Bilbao?

October is one of the two best months to eat in Bilbao — September being the other. The bonito season extends into early October, meaning marmitako (the Basque tuna stew with potato and choricero pepper paste) still appears on bar menus alongside the first heavier autumn preparations. Cod season is in full swing: kokotxas are at peak supply, bacalao preparations are on every traditional menu, and the Mercado de la Ribera runs full Tuesday-through-Saturday market service.

Weather in October averages 15 to 19°C on the Nervion estuary — cooler than August, comfortable for walking between the Casco Viejo and the Guggenheim waterfront, and without the summer crowds. Hotel prices drop 15 to 20% from the August peak.

For food travelers in the Basque Country specifically: San Sebastian Gastronomika runs October 5 to 7 at the Kursaal Congress Centre in San Sebastian, 100 kilometers east. The congress includes public tasting sessions that do not require industry credentials. Bilbao makes a natural base for a Basque food circuit — a bacalao lunch in the Casco Viejo and an evening pintxos circuit on Gastronomika day fit comfortably within 48 hours on the estuary.
