Let’s talk about tortilla española, also called tortilla de patatas. Not the wrap. Not the chips. This is Spain’s greatest magic trick: potatoes, onions, eggs, salt, and olive oil turning into something that tastes like way more than the sum of its parts.

I love this recipe because it is low-drama, pantry-friendly, and wildly versatile. Serve it hot for dinner with a salad, room temp for lunch, or chilled in neat little squares like the world’s coziest tapas. The goal is simple: tender potatoes, sweet onion, and eggs that set like custard, not rubber.

Why It Works

Soft, tender potatoes gently cooked in olive oil until they are creamy and sweet, not browned and crisp.
Onions that melt into the mix, adding sweetness and that savory depth you notice even when you cannot name it.
A controlled cook: low heat sets the eggs evenly so the center stays silky, not dry.
Flip confidence with a simple plate-and-pan method that keeps the tortilla intact and gorgeously golden.

Storage Tips

How to Store Leftovers

Refrigerate: Cool completely, then wrap slices or store in an airtight container for up to 4 days.
Serve later: Tortilla española is excellent cold or room temperature. If reheating, warm gently in a skillet over low heat or microwave in short bursts so the eggs do not toughen.
Freeze (optional): You can freeze slices, tightly wrapped, for up to 1 month. This is not the traditional move and the texture softens a bit after thawing, but it is handy for quick breakfasts. Thaw overnight in the fridge.
About that reserved oil: If you want to reuse it, strain out any bits, cool completely, then refrigerate in a sealed jar and use within 3 days for roasting potatoes or sautéing vegetables.

Common Questions

Is a Spanish tortilla supposed to be runny inside?

It depends on preference and region. Many people aim for a slightly custardy center, not raw. A good cue is this: when you gently shake the pan, the tortilla should look set at the edges and jiggle a little in the center. It will continue to set as it rests. If you want it fully set, cook a few minutes longer on the second side and rest it 10 minutes before slicing.

Do I have to use onion?

No, but I vote yes. Onion makes it sweeter and more complex. If onion is not your thing, skip it and add an extra pinch of salt to help the potatoes pop.

What potatoes work best?

Use a waxy to all-purpose potato like Yukon Gold or red potatoes. They hold together while still turning creamy. Russets work, but they can break down faster.

How do I flip it without ruining it?

Use a large flat plate (or a flat lid) bigger than your pan. Take the pan off the heat, then place the plate on top and hold it tightly against the skillet. Use oven mitts and keep your hands away from the rim, because a little hot oil can sneak out. Slide the tortilla onto the plate, invert the pan over it, then flip so the tortilla lands back in the pan. Do it with conviction, like you meant to do it that way all along.

Can I add chorizo, peppers, or cheese?

You can, and it will be delicious, but the classic is just potatoes, onion, eggs, salt, and olive oil. If adding extras, keep them cooked and not watery, and do not overload or the tortilla will not set neatly.

I have always had a huge passion for the culinary arts, people, working as a team, and so on. I wanted to pursue my love for cooking initially at Virginia Commonwealth University with a culinary arts degree; however, I instead decided to apply myself and acquire more practical skills. My end goal is to eventually open my own restaurant or similar establishment.

Fine mesh strainer or slotted spoon
Rubber spatula
Large flat plate (for flipping)
Chef’s knife and cutting board

The first time I made tortilla española, I treated it like an American omelet and tried to rush it. Bad plan. The magic is in the patience: potatoes that go soft in olive oil and eggs that set slowly like a savory custard. Now it is one of my favorite “feed everyone, impress no one on purpose” meals. Slice it up, set it on the table, and suddenly people are hovering in the kitchen like you just opened a tiny tapas bar.
