Tortilla Española

About This Recipe

Tortilla Española is Spain's beloved national egg dish — a thick, golden cake of potatoes and onions slowly poached soft in olive oil, then bound with beaten egg and set into a tender round. Despite its short ingredient list, it is entirely technique-driven: the potatoes must be cooked gently until creamy, never browned, and the tortilla is famously flipped mid-cook so both faces turn golden while the center stays just-set and juicy (jugosa). Served warm or at room temperature, it appears everywhere in Spanish life, sliced into wedges as a tapa, stuffed into a crusty bocadillo, or packed for a picnic. Each forkful balances soft potato, sweet onion, and silky egg — humble ingredients transformed by patience into something genuinely satisfying.

Ingredients

Serves 6

• 1 kgpotatoes (Yukon Gold), peeled and thinly sliced
• 2 largeonions, thinly sliced
• 8large eggs
• 1.5 cupsolive oil (for poaching)
• 2 tspsalt
• 1/2 tspblack pepper

Instructions

1. 1

   Slice potatoes

   Peel the potatoes and slice them into thin 3mm rounds, then salt lightly and let them sit 10 minutes before patting dry. Even, thin slices cook uniformly and turn meltingly soft in the oil bath rather than staying firm.

2. 2

   Poach potatoes and onions

   Heat the olive oil in a 26cm non-stick skillet over medium-low and add the potatoes and onions so they're nearly submerged. Cook gently, stirring now and then, 25-30 minutes until the potatoes are tender but never browned.

   This is poaching, not frying — keep the heat low so the potatoes go silky and the onions sweeten without color.

3. 3

   Drain

   Tip the potatoes and onions into a colander set over a bowl, reserving about 3 tbsp of the strained oil for cooking the tortilla. Let them cool slightly so the hot oil doesn't scramble the eggs in the next step.

4. 4

   Beat eggs

   Beat the eggs with salt and pepper, then fold in the drained potato-onion mixture and let it sit 10 minutes. Resting lets the eggs soak into the potatoes and absorb their starch, giving a more cohesive, creamy set.

   Lightly crush some of the potato as you mix for a denser, more traditional texture.

5. 5

   Cook tortilla

   Heat 2 tbsp of the reserved oil over medium heat, pour in the egg-potato mixture, and cook about 5 minutes until the edges and base are set while the top is still loose. Shake the pan occasionally to keep it free.

6. 6

   Flip

   Cover the skillet with a flat plate, hold it firmly against the pan, and invert in one decisive motion, then slide the tortilla back in browned-side up. Confidence matters here — a hesitant flip is what causes breakage.

   Work over the sink and use a plate wider than the pan to catch any runaway egg.

7. 7

   Cook second side

   Cook 5 minutes more, tucking the edges under with a spatula to round the shape. The finished tortilla should be golden outside and still slightly soft and juicy (jugosa) at the very center.

8. 8

   Serve

   Slide onto a serving plate and let it rest 5 minutes so the center finishes setting from residual heat. Serve warm or at room temperature, cut into wedges, as a tapa or light meal.

Variations

• •

  Add sautéed red peppers or sliced chorizo to the potato mixture.

• •

  Cheese tortilla: fold in grated Manchego.

• •

  Spinach or piquillo pepper versions for color and flavor.

• •

  Without onion (sin cebolla) for a purer potato-and-egg flavor.

Storage

Refrigerate up to 4 days, well wrapped. It is best enjoyed at room temperature, so take it out 20-30 minutes before serving; a quick warm-up in a low oven also works. It travels well, which is why it's a picnic and bocadillo staple.
