Spanish Tortilla (Tortilla de Patatas)
Spain's national dish: potatoes and onion gently cooked in olive oil, then set with egg into a thick round omelette. The ingredients are simple — the art is a juicy center. Great warm or cold.
Ingredients
Steps
- ⏲ 5 min
Peel and thinly slice the potatoes (3–4mm) and slice the onion.
- ⏲ 18 min
Pour a generous amount of olive oil into a pan over low heat, add the potatoes and onion, and 'confit' them — cook gently 15–20 minutes until tender, without browning (not a hard fry).
- ⏲ 2 min
Drain the potatoes and onion in a sieve (save the oil) and season with salt.
- ⏲ 5 min
Beat the eggs in a bowl, fold in the warm potatoes and onion, and let sit about 5 minutes to meld.
- ⏲ 3 min
Heat 1 tbsp oil in the pan over medium, pour in the mixture, and cook 2–3 minutes, tucking in the edges.
- ⏲ 4 min
Cover with a plate (or lid), flip the pan to turn it out, and cook the other side 2–3 minutes. Slide out while the center is still slightly juicy (jugosa); cool, then slice.
Tips & Variations
Variations
- Without onion (sin cebolla): Many purists skip the onion — a matter of taste.
- Chorizo or peppers: Add chorizo or roasted peppers for richness.
- Runny vs set: Leave the center juicy (jugosa) or cook it fully through.
- Pinchos: Cool, cube, and set on bread for a tapas-style bite.
Tips
- Confit, don't fry — cook the potatoes gently in oil until tender without color.
- Rest the potatoes in the egg for 5 minutes so the flavors meld.
- The flip is the key move — cover with a plate and turn it confidently in one go.
- Pull it off the heat while the center is slightly juicy; residual heat finishes it.
- The leftover olive oil is flavorful — save it for other cooking.
The basics behind this dish
- Browning and the Maillard ReactionMeat fails to brown for one of three reasons: it is wet, the pan is cool, or you put too much in at once. Plus how the brown film stuck to the pan becomes your sauce.
- Cooking Meat: Temperature, Resting, and Cutting Against the GrainDoneness is a core temperature, not a number of minutes. What resting actually does, how to handle a thick cut, and why the direction you slice changes the texture.
- Knife Skills: Grip, Cuts, and Why Size MattersHow you hold the knife matters more than how fast you cut. The pinch grip, the claw hand, and why uniform size is a cooking decision rather than a cosmetic one.
