Tortilla Española (Spanish Potato and Onion Omelette)

If there’s one dish that proves you don’t need a long ingredient list to make something unforgettable, it’s tortilla española. Just potatoes, onion, eggs, and really good olive oil, turned into something Spain has been arguing about, mostly whether it should have onion at all, for generations.

I fell for it on a trip near the Spanish border years before Sofia and Lucas came along, and it’s become my go-to whenever I want a Mediterranean breakfast that isn’t Portuguese but still feels like home. It sits comfortably next to patatas bravas and Spanish tomato toast (recipes on the site) on our weekend brunch table.

The flip is the part everyone worries about, and yes, the first time I tried it I lost about a third of the tortilla to my stovetop. It gets easier fast, I promise, and even a slightly messy flip still tastes incredible.

Tortilla Española Recipe

Prep time: 15 minutes · Cook time: 35 minutes · Total: 50 minutes · Servings: 6 · Calories: ~310 per serving

Ingredients

• 5 medium Yukon Gold potatoes (about 2 pounds), peeled and thinly sliced
• 1 medium yellow onion, thinly sliced
• 1 cup olive oil, for frying
• 6 large eggs
• Salt, to taste

Instructions

1. Heat the olive oil in a 10-inch nonstick skillet over medium heat.
2. Add the potatoes and onion, season with salt, and cook gently, turning occasionally, 20 to 25 minutes, until tender but not browned. They should be almost poaching in the oil.
3. Drain the potatoes and onion in a colander set over a bowl, reserving 2 tablespoons of the oil; let cool slightly.
4. In a large bowl, beat the eggs with a pinch of salt. Fold in the drained potatoes and onion, pressing gently so everything is coated in egg.
5. Wipe out the skillet and heat the reserved 2 tablespoons of oil over medium-high heat.
6. Pour in the egg and potato mixture, spreading evenly. Cook 3 to 4 minutes, shaking the pan occasionally, until the edges set.
7. Place a large plate over the skillet and, holding it firmly, flip the tortilla onto the plate.
8. Slide the tortilla back into the skillet, uncooked side down, and cook 2 to 3 more minutes for a soft center, or a bit longer if you prefer it fully firm.
9. Slide onto a plate, let rest 5 minutes, and cut into wedges to serve warm or at room temperature.

Recipe Notes

• The potatoes should cook low and slow in the oil, almost like confit, so they turn creamy rather than crisp; this is the single biggest difference between a good tortilla and a mediocre one.
• A well-seasoned nonstick or carbon steel skillet makes the flip much easier and less nerve-wracking the first few times.
• Spaniards argue fiercely over whether tortilla española should include onion at all; I’m firmly on the pro-onion side, but leave it out if you want the purist’s version.
• This keeps well at room temperature for a few hours, which makes it a favorite for picnics and tapas spreads.
