Tortilla de patatas

A classic Spanish tortilla, thick and soft, with melting potatoes confited in olive oil, barely set eggs, and a touch of sweet onion. It is served warm or at room temperature, in generous slices.

Ingredients

  • 700 g waxy potatoes
  • 6 pieces eggs
  • 1 piece yellow onion
  • 250 ml extra-virgin olive oil
  • 1 tsp fine salt

Method

  1. Peel the potatoes and the onion; cut the potatoes into thin, irregular slices and thinly slice the onion so it melts during cooking.
  2. Heat the olive oil in a wide skillet over medium-low heat, then add the potatoes, onion, and salt; the oil should simmer gently, never sizzle loudly.
  3. Cook, stirring gently occasionally, until the potatoes are very tender, almost confited, and break easily under the spatula.
  4. Drain the potatoes and onion in a colander, reserving the oil for another use; let cool slightly to avoid coagulating the eggs too quickly.
  5. Beat the eggs in a large bowl until blended but not frothy, then fold in the potatoes and onion; let rest until the mixture is soft and well cohesive.
  6. Pour a drizzle of the reserved oil into a nonstick skillet, heat over medium, then add the mixture; gently pull the edges toward the center at first to form a thick cake.
  7. Lower the heat and let set until the edges are firm, the bottom golden, and the center still slightly jiggly.
  8. Flip the tortilla using a flat plate, slide it back into the skillet, and continue cooking until the outside is set but the center remains soft.
  9. Let rest off the heat before cutting, so the tortilla firms up without drying out; serve warm or at room temperature.
