Tortillas de Bacalao: 4 Recetas Tradicionales (Vasca, Andaluza, Catalana, Francesa)

Cod Fritters: 4 Traditional Recipes (Basque, Andalusian, Catalan, French)

May 25, 2026Maria José Sáez Pastor⏱ 4 min de lectura

In short: 4 traditional cod omelets: Basque from Bilbao (with sautéed onion and piparra), Andalusian (fried cod), Catalan (on bread with tomato), French (stuffed, creamy). Ingredients, techniques, and pairings.

Basque cod omelet (Bilbao): the mother of all

The Basque cod omelet is the most widespread and internationally recognized version. It features shredded cod, very well sautéed onion, and, optionally, Italian green pepper. Some families add piparra (pickled Basque chili pepper) as a distinctive touch.

Ingredients (2 people): 100g desalted shredded cod, 4 eggs, 1 large onion, 50ml EVOO, salt, pepper.

Method: Sauté onion for 25 min over low heat. Add drained cod, sauté for 3 min. Beat eggs and mix. Cook omelet in a small pan over medium-low heat, flipping once. Serve with piparra on top.

Andalusian cod omelet: the "fried cod omelet"

Andalusian version, particularly typical of Cadiz and Seville: the cod is first lightly fried and then mixed with the egg. The result is an omelet with crispy pieces of cod in every bite.

Ingredients (2 people): 100g desalted cod in small flakes, 4 eggs, 1 minced garlic clove, fresh parsley, EVOO.

Method: Fry the cod in EVOO for 1 minute. Set aside. Beat eggs with garlic and parsley. Mix with fried cod. Cook omelet 2-3 min per side. Serve with lemon.

Truita amb bacallà (Catalan omelet)

Catalan version, simple and direct: shredded cod mixed with egg, served on bread with tomato. It is the classic Catalan neighborhood tavern breakfast.

Ingredients (2 people): 100g shredded cod, 4 eggs, salt. To serve: toasted rustic bread + ripe tomato + EVOO.

Method: Mix cod with beaten egg. Cook omelet 2 min per side. Serve on bread with rubbed tomato.

French cod omelet (creamy)

More modern version: rolled French omelet filled with cod and piparra. A finer aesthetic, ideal for an elegant appetizer or brunch.

Ingredients (2 people): 4 eggs, 80g desalted shredded cod, 2 chopped piparras, butter, salt.

Method: Heat cod and piparras together for 2 min. Set aside. Beat eggs with salt. In a small pan with butter, make a baby French omelet (lightly cooked, creamy). Fill with cod+piparras before rolling. Serve immediately.

Common tricks for perfect omelets

Good non-stick pan. Not suitable for creamy French omelets.

Hot oil. If it's cold, the omelet absorbs fat.

Fresh, gently beaten eggs. Not with a blender, do not incorporate air.

Do not salt until the end. Desalted cod still adds salt. Taste before adding more salt.

Small omelet rather than large. Individual 2-egg omelets always turn out better than family-sized 12-egg omelets.

Shredded cod for omelets

Shredded Gadus morhua cod, perfect flakes to integrate into eggs. Desalted and ready for your omelet in any style.

Frequently asked questions

Which is the most traditional cod omelet?
The Basque one, also called "Bilbao cod omelet". It contains well-drained shredded cod, sautéed onion, and optionally piparra chili. It is one of the oldest omelets in Basque cuisine, predating potatoes.
What cod should I use for omelets?
Desalted shredded for all versions. Flakes of 1-2 cm so they integrate into the egg. If you buy loin, break it apart by hand. Important: well-drained (excess water makes the omelet watery).
How many eggs per omelet?
Individual omelet: 2 eggs per person + 50g cod. Family omelet (8 people): 12 eggs + 300g cod. The egg:cod ratio is 1:25 by weight (1 50g egg for every 25g shredded cod).
Basque omelet with or without potato?
Without potato. The classic Basque cod omelet does NOT contain potato (the version with potato exists but is a minority). Sautéed onion yes, plenty. Italian green pepper is also optional.
What is "piparra"?
Basque chili pepper pickled in vinegar, not spicy (medium or no heat). It is called piparra or Ibarra chili. It is typical as a garnish for Basque omelets and gildas. You can find it in a jar or can.
Is Catalan esqueixada omelet the same thing?
No. Esqueixada is NOT an omelet — it is a Catalan salad of raw shredded cod with tomato, pepper, and olives. A "tortilla with esqueixada" would be a modern hybridization. The traditional Catalan cod omelet is similar to the Basque one with a touch of pa amb tomàquet.
Can these omelets be made with fresh cod?
Technically yes, but the flavor changes a lot. Salted/desalted cod has the concentrated umami character that gives the omelet its personality. With fresh cod, it is milder and loses its traditional "zing."

To finish

There are as many cod omelets as there are regions in Spain: the Basque is the most deeply rooted, the Andalusian the most flavorful, the Catalan the quickest, and the French the most elegant. If you have never tried more than one, start with the Basque and then experiment. With quality shredded cod, they all work.
