Prep and Cook Time
- planning: 15 minutes
- Cooking: 30 minutes
- Total Time: 45 minutes
Yield
- Serves 4 to 6 peopel
Difficulty level
- Medium (requires attention to timing and technique)
Ingredients
- 6 medium Yukon Gold potatoes (about 2 pounds), peeled and thinly sliced
- 1 large yellow onion, thinly sliced
- 6 large farm-fresh eggs
- 1 ½ cups extra-virgin olive oil, for frying
- 1 teaspoon fine sea salt, plus more to taste
- Freshly ground black pepper, to taste
Instructions
- Heat the olive oil in a large non-stick skillet over medium heat until shimmering but not smoking. The key is gently frying, not deep frying.
- Add the sliced potatoes and a pinch of salt. Cook slowly, stirring occasionally, for about 10 minutes until tender and just beginning to turn golden. Avoid browning too fast to keep them soft inside.
- Introduce the sliced onions to the skillet with the potatoes. Continue to cook over low-medium heat for another 10 minutes, stirring often to ensure even caramelization. The potatoes and onions should meld into a tender, aromatic mixture.
- While the potatoes and onions cook, whisk the eggs in a bowl, seasoning generously with salt and pepper. This mixture will envelope the potatoes and bind the tortilla.
- Once cooked, use a slotted spoon to transfer the potato and onion mixture directly into the eggs, stirring gently to coat everything evenly.
- Remove excess oil from the skillet, leaving just enough to prevent sticking, then heat over medium.
- Pour the egg-coated potato and onion mix back into the skillet, spreading it out evenly. Cook undisturbed for about 4-5 minutes until the edges set but the center remains slightly runny.
- Prepare a large plate to flip the tortilla. Cover the skillet with the plate, invert quickly but carefully to transfer the tortilla onto it, then slide the tortilla back into the skillet, uncooked side down, to finish cooking for another 4 minutes.
- Test for doneness by gently shaking - the tortilla should be cooked through but still moist in the center.
- Slide the tortilla onto a serving plate and allow it to rest for a few minutes before slicing. This resting step enhances the texture and flavors.
Chef’s Notes: Tips for Success
- Select the right potatoes: Yukon Golds are ideal for their balance of waxy and starchy textures, yielding a creamy interior with crisp edges.
- Control your oil temperature: Maintaining moderate heat helps the potatoes cook gently without burning, crucial for tenderness.
- Patience is key: Slow cooking the onions throughout prevents bitterness and develops natural sweetness.
- Practice the flip: Using a plate slightly larger than your skillet makes turning easier. Don’t rush it - a confident, quick motion avoids spills.
- Variations: For a heartier tortilla, add chopped fresh parsley or a handful of finely diced roasted red peppers.
- Make-ahead tip: Tortilla tastes even better the next day, so prepare in advance and gently reheat with a splash of olive oil in a warm pan.
Serving Suggestions to Elevate Your Classic Spanish Dish
