Tortilla española
Thick Spanish omelette of slow-cooked potato bound in egg, served by the slice. Debate over whether to include onion is a national pastime.
Tortilla española (also tortilla de patatas) is the everyday Spanish omelette: potato slices cooked slowly in olive oil until tender, then folded into beaten egg, poured back into the pan, and flipped halfway through so both sides set golden. The result is dense, custardy in the middle, eaten warm or at room temperature, sliced into wedges and served as a tapa, in a sandwich (bocadillo de tortilla), or as a quick lunch. Every Spanish family has a tortilla recipe and an opinion on whether onion belongs in it (the con vs sin debate is genuinely heated). The interior should be slightly runny in the middle; a fully-set tortilla is considered overcooked by most.
How it's served
By the slice as a tapa, in a bocadillo, or as a main course with a salad and bread. Tortilla bars in Madrid (the most famous is Casa Dani) build a whole identity around it. The texture should be soft and slightly liquid in the centre, not fully cooked through.
Regional variation
The big split is onion. Tortilla con cebolla is the Castilian classic; tortilla sin cebolla is the purist preference. Both are common across Spain. Catalan kitchens often add escalivada or butifarra. Galician restaurants sometimes go thinner; Andalusian bars often serve a softer, runnier version.

Frequently asked
What's in a Spanish tortilla?
Potato, egg, olive oil, salt, and sometimes onion. That's it. The potatoes are sliced thin and cooked slowly in oil until tender, then mixed with beaten egg and set in a hot pan. The dish is thick (an inch or so), dense, and cut into wedges.
Onion or no onion in tortilla?
Genuine national debate. Tortilla con cebolla (with onion) is sweeter and softer; tortilla sin cebolla (without) is purer and firmer. Both are correct. Asking someone their preference in Spain is roughly equivalent to asking about pineapple on pizza, with similar emotional intensity.
Is a tortilla the same as an omelette?
Distantly related. A French omelette is thin, lightly set, and folded around a filling, eaten hot. A Spanish tortilla is thick, dense, potato-based, sliced into wedges, and eaten warm or at room temperature. Both use eggs as the binder; the format and texture differ completely.
