Zurrukutuna is one of the most emblematic and ancient soups of Basque cuisine: a humble dish of shredded cod, soup bread, choricero peppers, and egg, cooked in a bone broth that concentrates all the flavor of the sea. Its name in Euskera literally means "spoon broth" and perfectly summarizes its essence: a survival dish transformed into a delicacy, which has passed from the kitchens of Basque fishermen to the menus of the best restaurants in the Basque Country. Marc González Sáez, from Mercat del Ninot in Barcelona, teaches you the recipe step by step with the tricks of a professional who has been working with cod since 1990.

Zurrukutuna: Origin and History
Zurrukutuna originated in the rural and fishing areas of the Basque Country, at a time when wasting food was unthinkable. It was a pure utilization dish: stale bread from the day before, leftover cod that didn't sell at the market, and choricero peppers hanging in the kitchens. All of this was cooked in water—or better yet, in the broth from cooking the cod itself—with a poached egg on top to provide protein and richness.
The name zurrukutuna comes from Euskera: "zurru" (to slurp) and "kutuna" (pleasant or beloved). It is, literally, a "beloved slurp." And that is exactly what it is: a comforting, simple soup, drunk (or eaten with a spoon) directly from the plate, slurping the hot broth with pieces of soaked bread and flakes of cod.
During Lent, when the Church prohibited the consumption of meat, zurrukutuna was one of the star dishes in Basque farmhouses. It was economical, nutritious, and complied with the precept of abstinence. Today, far from being a dish of necessity, zurrukutuna appears on the menus of Michelin-starred restaurants as a tribute to ancestral Basque cuisine.
Ingredients (4 servings)
- 300 g desalted cod, hand-shredded into flakes
- 200 g day-old rustic bread (stale or semi-stale)
- 4-5 dried choricero peppers (or 2 heaped tablespoons of choricero pepper pulp)
- 4 cloves garlic, sliced
- 1 large onion, finely chopped
- 1 teaspoon sweet paprika from La Vera
- 800 ml cod fumet (or quality fish broth)
- 4 eggs
- Extra virgin olive oil
- Salt (carefully: cod adds salinity)
- Fresh parsley, chopped
The cod broth or fumet
As with marmita, the broth makes the difference between a passable zurrukutuna and a memorable one. If you can, make a fumet with the cod bones, skin, and head: put them in a pot with cold water, a leek, a carrot, and parsley. Bring to a gentle boil and cook for 25 minutes. Strain and it's ready.
This bone broth provides natural gelatin that gives the dish a rich, slightly thick texture, enveloping the bread and cod like a hug. No commercial broth can replicate this. However, if you don't have cod scraps, a homemade fish fumet or even a good quality packaged fish broth (read the label: fish, water, vegetables, salt, and little else) is an acceptable alternative.
Step-by-step preparation
Step 1: Prepare the choricero peppers (30 minutes)
Place the choricero peppers in a bowl with hot water for 30 minutes. Once soft, open them and scrape out the pulp with a knife, separating it from the skin. Reserve the pulp. The soaking water, filtered through a fine sieve, can be added to the broth.
Step 2: The base sofrito (10 minutes)
In a wide saucepan (earthenware if you have one), heat a generous drizzle of olive oil over medium heat. Add the sliced garlic and brown it lightly. Remove it before it darkens and set aside. In the same oil, sauté the onion over medium-low heat for 8-10 minutes until completely translucent and sweet.
Add the sweet paprika from La Vera (sauté for a second, stir quickly so it doesn't burn) and the choricero pepper pulp. Mix well and cook for 1-2 minutes to combine.
Step 3: Bread and broth (10 minutes)
Cut the stale bread into slices or pieces of about 2-3 cm. Add it to the sofrito and stir so that it soaks up the oil, onion, and choricero peppers. This step is crucial: the bread absorbs the flavors of the sofrito before receiving the broth.
Pour the hot cod fumet over the bread. Stir gently and bring to a boil. Reduce the heat and cook for 8-10 minutes. The bread will partially break down, thickening the broth and creating that characteristic texture of zurrukutuna: neither a liquid soup nor a thick porridge, but a silky and comforting intermediate point.
Step 4: The cod (5 minutes)
Shred the cod by hand into medium flakes (not too small: they should have presence in the dish). Add it to the saucepan and cook over low heat for 4-5 minutes. The cod only needs to heat through and release its juices into the broth. Do not overcook it: the flakes should remain whole and juicy.
Step 5: The eggs (4-5 minutes)
With a spoon, make 4 indentations on the surface of the soup. Crack an egg into each indentation. Cover the saucepan and cook over low heat for 4-5 minutes, until the whites set but the yolks remain runny. This is the finishing touch that transforms zurrukutuna from a soup into a complete meal.
Sprinkle with the reserved browned garlic and fresh chopped parsley. Serve directly from the saucepan, with a spoon for each diner.
Shredded cod is the soul of zurrukutuna.

Soup bread: what type to use
Not just any bread works for zurrukutuna. You need a rustic bread with a thick crust and dense crumb, preferably day-old (semi-stale). Industrial sliced bread instantly disintegrates and creates a textureless mush. Sourdough bread with an open crumb also breaks down too quickly.
The ideal bread is:
- Castilian rustic bread (pan de hogaza): compact crumb, thick crust, wheat flavor. It partially disintegrates in the broth but maintains some textured pieces, creating the perfect contrast.
- Basque corn bread (artoa): the traditional option in Basque farmhouses. Denser and with a slightly sweet flavor that complements the choricero peppers.
- Whole wheat rustic bread: a modern alternative with more flavor and nutrients.
If your bread is fresh, dry it in the oven at 100°C for 20 minutes before using it. Dry bread absorbs the broth without completely disintegrating, which is exactly what we're looking for.
Zurrukutuna variations
Gratinad Zurrukutuna
A very popular modern version: prepare the soup up to step 4 (without eggs). Pour it into individual earthenware dishes, crack an egg into each, and cover with grated Idiazábal cheese. Gratin in the oven at 200 °C for 8-10 minutes until the cheese is golden and bubbling. Smoked Idiazábal provides a spectacular contrast with the cod and choricero peppers.
Creamy Zurrukutuna (restaurant version)
Some Basque chefs have modernized zurrukutuna by partially blending it: blend 60% of the soup and mix with the remaining 40% unblended. The result is a cream with pieces of cod that maintains the rustic essence but with a more refined texture. It is served in a deep bowl with a poached egg on top (instead of poached in the soup) and a drizzle of extra virgin olive oil.
Zurrukutuna with clams
Add 250 g of well-washed clams (purged in salted water for at least 2 hours) in the last 5 minutes of cooking, along with the cod. The clams open in the hot broth, adding their marine juice. It's a more luxurious version of the original humble dish.
Frequently Asked Questions
Is zurrukutuna a soup or a stew?
Zurrukutuna is technically a thick soup, halfway between soup and stew. Its texture depends on the amount of bread and broth: with more broth it is more liquid (soup), with more bread it is thicker (almost a stew). The traditional version is quite thick: it is eaten with a spoon but not drunk. It is what in Basque cuisine is called a "spoon dish."
Can it be prepared without an egg?
Yes. The poached egg is a later addition to the original recipe; older versions did not include it. Without egg, zurrukutuna is still a tasty and comforting dish. If you want extra protein without egg, increase the amount of cod to 400-500 g.
Can I use fresh bread instead of stale bread?
It's not ideal. Fresh bread absorbs the broth too quickly and completely disintegrates, creating a mushy texture. Stale or semi-stale bread absorbs the broth gradually, maintaining some textured pieces and creating the contrast that defines zurrukutuna. If you only have fresh bread, dry it for 20 minutes in the oven at 100 °C.
How long does zurrukutuna last in the fridge?
The base (broth with bread, sofrito, and cod) lasts 2-3 days in the refrigerator. The bread will continue to absorb broth and the soup will thicken considerably: when reheating, add extra broth to restore the desired texture. Eggs should be cooked fresh when reheating.
What other Basque cod dishes are similar?
The family of Basque cod dishes is extensive: bacalao al pil-pil (confit in oil), Club Ranero (pil-pil with piperrada), marmita de bacalao (stew with potatoes), bacalao a la vizcaína (choricero pepper sauce). Zurrukutuna is distinguished by the use of bread as a main element, something that does not appear in the others. It is the oldest and most humble dish in the family.
Is it a child-friendly dish?
Absolutely. The soft texture of the soaked bread, boneless shredded cod, and flavorful broth make it an ideal dish for children aged 2-3 and up. Reduce or omit the chili pepper if using, and omit the paprika if you want a milder flavor. Many Basque children grow up eating zurrukutuna as one of their first spoon dishes.
Zurrukutuna is proof that great cuisine is born from scarcity, not abundance. Stale bread, cod scraps, dried peppers, and an egg. That's all. And yet, the result is a deep, comforting dish, full of nuances. It is real cooking—the kind passed down from generation to generation that needs no embellishments or artifice. If you've never tried zurrukutuna, prepare to discover that the best soups in the world don't contain expensive ingredients: they contain soul.
