Tortilla Española
Potato, egg, onion, olive oil, salt — five ingredients into Spain's universal bar-counter wedge.
In repertoire since Dec 2025
Potato cooked in oil like a confit.
The Spanish tortilla is not really an omelette in the French sense; it's a confit of potato and onion in olive oil, then bound with egg and set in a pan. The technique reveals what makes a great tortilla different from a fine one: the oil is low (130°C), the time is long (25 minutes), and the potato emerges tender enough to mash with a fork before the egg ever enters the picture.

Then, the plants.
Each ingredient held water and minerals, built sugar out of light over weeks or months, ripened, and was picked. A few ingredients (salt, water) came from a different elemental story.
- Ingredient
Waxy potatoes
600 g waxy potatoes, peeled, sliced 3 mm thick
Slice with a mandoline if you have one. Uniform thickness means uniform cooking; a mixed slice is a tortilla with crunchy and mushy patches.

- Ingredient
Yellow onion
1 large yellow onion, thinly sliced
The eternal Spanish argument: *con cebolla* or *sin cebolla*. This recipe is *con*; the Betanzos coast in Galicia is *sin*. Both are correct.

- Ingredient
Olive oil
500 ml extra-virgin olive oil
Yes, this much. The potatoes confit in oil at low temperature — most of the oil is reused or strained and saved for another cook.
Liguria olive mill - Ingredient
Eggs

Tortilla Española
Potato, egg, onion, olive oil, salt — five ingredients into Spain's universal bar-counter wedge.
The Spanish dish that’s eaten everywhere and is iconic everywhere. From a tapas counter in Madrid to a backpacker’s lunch on the Camino, tortilla is the universal Spanish meal — protein, starch, fat, salt, on a plate that costs almost nothing to make and travels well.
A note on naming: this is tortilla in Spanish, meaning “little cake.” It is not the Mexican tortilla (the flatbread). Same Spanish word, different food, different countries, four hundred years of confusion. In Spain, the flatbread version is called tortilla mexicana if it appears at all.
Jugosa or cuajada?
Juicy or set. Northern Spain wants the centre almost custardy; the south and Madrid go firmer. Both are tortilla. The argument is national, perpetual, and irresolvable.
