Ingredients

• 2½ cups extra virgin olive oil

• 1 yellow or white onion, thinly sliced
• 6 large eggs, beaten
• 2 teaspoons crushed sea salt, divided

Instructions

1. Cook the potatoes and onion:
   In a large skillet, heat the olive oil over medium heat. Add the potatoes and onion, making sure they’re mostly covered in oil (add a bit more if needed). Season with 1½ teaspoons of salt.
   Cook over medium-high heat, maintaining a gentle simmer, for 8–12 minutes, stirring occasionally, until the potatoes are just fork-tender. Avoid overcooking — they should be soft but not falling apart.
2. Drain and cool:
   Pour the mixture into a colander to drain, reserving the oil. Taste the potatoes and season with a bit more salt if needed. Let them cool for a few minutes.
3. Mix with eggs:
   In a large bowl, beat the eggs with the remaining ½ teaspoon salt. Add the cooled potatoes and onion, gently tossing to coat everything evenly.
4. Cook the tortilla:
   Heat a little of the reserved oil in a 10-inch nonstick skillet over high heat. Once hot, pour in the potato mixture. Cook on high for 1 minute, then reduce heat to medium-low and cook for about 5 minutes.
   Run a spatula around the edges to prevent sticking and shape the tortilla’s sides.
5. Flip the tortilla:
   When the edges and top start to firm up (but the center is still slightly soft), place a large plate over the skillet. Carefully flip the tortilla onto the plate so the cooked side is facing up.
6. Finish cooking:
   Slide the tortilla back into the skillet, cooked side up. Gently tuck the edges under with a spatula to keep its round shape.
   Cook for 1 minute on high heat, then reduce to low heat and cook for another 2–3 minutes, or until set in the center. A knife or toothpick inserted should come out clean.
7. Serve:
   Flip the finished tortilla onto a serving plate. Serve warm or at room temperature, sliced into wedges or squares.

Tips

• Use the right potatoes: Waxy or semi-waxy varieties like Yukon Gold hold their shape well.
• Control the heat: Too high, and the potatoes will brown instead of softening; too low, and they’ll absorb too much oil.
• Flip carefully: Use a large, flat plate and confidence — it’s easier than it looks!
• Reuse the olive oil: The strained oil can be used again for future cooking; it’s infused with wonderful flavor.

Variations and Substitutions

• Add vegetables: Try bell peppers, spinach, or zucchini for a colorful twist.
• Make it cheesy: Stir in a handful of shredded Manchego or mozzarella before cooking.
• Add protein: Include bits of cooked chorizo, ham, or bacon for a heartier version.
• No onion version (Tortilla de Patatas sin cebolla): Traditionalists debate this — feel free to skip the onion if you prefer a pure potato flavor.
• Lighter version: Reduce the olive oil and briefly boil or microwave the potatoes before cooking in the pan.

FAQs

Can I make it ahead of time?
Yes. Tortilla de Patatas keeps well for up to 2 days in the fridge. Bring to room temperature before serving or gently reheat in a skillet.

Do I need to use so much oil?
The oil is key for the signature texture and flavor, but most of it is drained and reused — the potatoes are gently confited, not fried.

Can I bake it instead of frying?
Yes! Combine everything in an oven-safe skillet and bake at 375°F (190°C) for 20–25 minutes, until set.

How do I know when it’s done?
It should feel firm in the center, and when you insert a knife, it should come out clean.
