What is tortilla española?
Tortilla española is a thick omelette of potatoes and eggs, made by gently cooking sliced potato (and usually onion) in plenty of olive oil, then folding it into beaten egg and cooking it in a frying pan until set on both sides. It's served in wedges, warm or at room temperature. You'll find it in nearly every bar in Spain.
What's in it
- Potatoes: thinly sliced or diced, cooked slowly in olive oil until soft rather than crisp.
- Eggs: beaten with salt.
- Onion: optional, and the subject of a long national argument. Con cebolla has it; sin cebolla doesn't.
- Olive oil: a lot of it, most of which is drained off before the egg goes in.
Texture divides people too. Jugosa means juicy, with a soft, almost runny centre; cuajada means fully set. Variants add chorizo, green pepper, spinach, tuna or cheese.
Allergens and diets
Assume egg. A tortilla is mostly egg and potato, and a jugosa tortilla has a lightly cooked centre. If you've been told to avoid undercooked egg, ask for it well set (bien cuajada).
The standard recipe has no flour or dairy. Gluten comes in when it's served on a slice of bread, as a pincho de tortilla often is, or inside a bocadillo (a sandwich in a baguette-style roll). A few cooks add milk to the eggs for softness, so ask if milk matters to you.
The potatoes are usually cooked in a pan of their own, but in a busy bar they may be fried in shared oil. If you have a severe fish or shellfish allergy, it's worth asking. A plain tortilla is vegetarian, and with no meat or alcohol it suits most religious diets, though chorizo versions contain pork.
On the menu
On a bar counter or menu it appears as tortilla española, tortilla de patatas or just tortilla, sold as a pincho (single slice), a ración (a larger plate) or occasionally whole. Tortilla francesa is a plain folded omelette, not this. In Mexico and Central America, a tortilla is a flatbread, which is a completely different thing.
