Spanish Tortilla

Tortilla espanola is Spain’s most iconic dish, and it only needs four ingredients: potatoes, eggs, olive oil, and salt. This thick potato omelette shows up in every tapas bar, cafe, and home kitchen across the country, served in wedges at any temperature from hot to room temperature.

The potatoes get slowly sauteed in olive oil until soft, not crispy. You want them tender enough to break apart slightly when mixed with the beaten eggs. That slow cooking is what separates a good tortilla from a bad one. Rushing with high heat gives you fried potatoes in scrambled eggs, which is a different thing entirely.

The plate-flip technique takes nerve the first time. Once the bottom is set and bubbles appear on top, you place a plate over the pan, flip the whole thing, then slide the uncooked side back into the pan. It should feel solid when finished, set all the way through but still slightly creamy in the center.

Kitchen Tips

• Slice potatoes thin and uniform so they cook at the same rate. Thick, uneven slices mean some are mushy while others are still crunchy.
• Keep the heat low the whole time. A Spanish tortilla is never cooked on high heat. Patience is what makes it tender.
• Oil the plate before flipping. A dry plate sticks and the tortilla tears apart on the turn.

Variations

• Con cebolla: Add a thinly sliced onion to the potatoes while they cook. This is the great Spanish debate, but onion adds sweetness that many prefer.
• Pepper and chorizo: Toss in diced roasted red pepper and a few slices of cured chorizo for a heartier version.
