Author Notes: With a recipe that contains little more than eggs, potatoes, and onions, you will find many different techniques applied to the preparation of each ingredient. Some call for shallow frying the potatoes in oil and using the oil to cook the tortilla. Some call for cooking the tortilla on the stovetop and flipping it several times while cooking, in order to firm it up and round the edges. I've done this and it produces a great tortilla but not everyone has two pans the same size or, understandably, the will to invert a steaming hot panful of eggs into another hot pan.

For the version I'm sharing here -- which you could call Spanish-ish Tortilla -- I took a nod from Italy and cooked the tortilla like a fritatta (I also added a sprinkling of Parmesan cheese). You can eat it hot, if you like, but it also makes for a great lunch or snack once it's cool.

Serves 6

  • 2 pounds white or Yukon Gold potatoes, peeled
  • Salt
  • 1 medium onion, chopped
  • 3 tablespoons olive oil or vegetable oil
  • 8 eggs
  • Freshly ground black pepper
  • 1/3 cup freshly grated Parmesan cheese
  • 1 1/2 tablespoons unsalted butter
  1. Place the potatoes in a medium pot. Cover with water, season with about a tablespoon of salt, and bring to a boil. Reduce the heat and simmer until the potatoes are just tender when prodded with a fork, 20 to 25 minutes. Drain and let cool, then cut into 1/8-inch slices and put them in a large mixing bowl.
  2. Heat the oven to 400 degrees. Warm 1 1/2 tablespoons oil in a medium pan over medium heat. Add the onions, season with salt, and cook until translucent and lightly browned, about 10 minutes. Scrape the onions into the bowl with the potatoes.
  3. Lightly whisk the eggs until smooth, then add them to the potatoes and onions, and gently fold everything together. The potatoes should not be sticking together -- make sure the egg separates each slice. Season with salt and pepper and fold once more.
  4. Set a large nonstick or well-seasoned cast iron pan over medium high heat. Add the remaining 1 1/2 tablespoons oil and the butter. When the butter foams, pour in the potato-and-egg mixture and pat it down so it's even on the top. Sprinkle the cheese on top, let the eggs set around the edges, and transfer the pan to the oven. Bake until the eggs are almost set in the middle and the tortilla is browned around the edges, about 20 minutes.
  5. Remove the pan from the oven and let it cool on the stovetop. Run a thin spatula or knife around the edge of the tortilla to loosen it, then invert it onto a plate (this may be a 2-person job). If you'd like to serve the tortilla warm, invert it while it's still warm. Slice and serve. If you'd like to serve it with garlic mayonnaise, I won't argue.

Tortilla in Argentina means what it does in Spain. Americans are familiar to the "tortilla" used by Central Americans and Mexicans -- closer proximity and more of them in the USA. But, true, it is an omelet and can be eaten for any meal, hot or cold. When cold and cut, fingers or toothpicks; eaten hot, a lovely mixed or green salad with it is perfect!.

I absolutely love this recipe! It's easy and tastes delicious. However, I have a suggestion that I think helps coating the potatoes. In a bowl I whisked the eggs, added salt and pepper, then the onions. And finally the sliced potatoes. With a spatula I had to separate some, but it was very easy and delicious once again!

Please, Spanish tortilla in the oven?

yeah, the pic is great, the layering is perfect, but doesn't look like it was created by the "stir it all together" method described in the recipe.

Beautiful pic. Perhaps since Americans seem to need to create fusion versions of every simple authentic dish from other countries, take off "Spanish" from the recipe title. Parmesan cheese is never used. Stove-top / flip method is the norm. Some of my tias in Spain add a small pinch of baking powder to the egg mix to create a puffier version. Also, don't add too many potatoes...like making a good paella, it's about the art of balancing the ingredients. (This came to mind when I've seen American friends make paella that is absolutely overfilled w/ chicken.)

How many potatos should you use? Can you post your recipe? My son went to Spain and adored this dish. I would like to make him an authentic one like his host mom made him!! Thanks a bunch

Frankie, look for penelope casas recipe and technique, it is a traditional SPANISH tortilla. This is not. Flipping is easy, just follow her instructions & use a non-stick pan.

Those stupid Americans, always trying to subvert recipes. This should only be allowed to be printed in Spanish so those idiots would be prevented from using unapproved ingredients and methods.

I make this all the time for guests with a salad. I have found that it is important that the potatoes be well seasoned and tasty, BEFORE you pour on the eggs. I don't get a good separate potato feeling from mixing the eggs with the potatoes beforehand.

Jorge Obrayen--Interesting. Can you tell me if the eggs are just added to the fried potatoes after they are crisp and quickly cooked, or does one mix the (fried potatoes) in a bowl?

While these ingredients reflect the tortilla - less the Italian cheese - this is more or a potato frittata. The traditional Spanish kitchen had no oven and fried the potatoes. This approach is not unlike Spanish "tapas" with Japanese ingredients.

agree! I hate seeing people manipulate a dish that is already perfected & still call it a tortilla!

This makes me so happy. I just spent 10 days doing a culinary tour of Spain with fellow culinary students. We learned how to make this and consumed our fair share. It just makes me smile to stumble across this

I've been serving spanish tortilla in Baraka restaurant for quite some time now, with different variations. But what makes it SOOO special, is that we coat little pieces of potatos in olive oil, and then we bake them until crispy. The onions, on the other side, we sautee them until really tender, but not caramelized. We cool everything thoroughly. The pan should be oiled and smoking hot, and the potatos and onions already combined with the eggs and well seasoned. Toss into the pan, until a golden egg skin forms on the bottom (you'll have to guess this). And then, skills! Flip the tortilla, using a plate or a flat lid to help you transfer out, and then back in. If you like it babee, it'll take you like 3 more minutes on medium slow fire. This is how WE like it. Thank you for everything, I enjoy all of this so much.

What should have been explained is that "tortilla" is the Spanish word in Spain for an omelet. Spanish-speaking Americans use the word "tortilla" for the cornmeal dish that Americans know. "Frittata" is the Italian word for such an omelet.

Does one layer with the tortillas? I'm confused.

Tortillas are not in the ingredient list and barely mentioned in the recipe. I'm assuming one puts the cooked potato, egg mixture in a tortilla.

No. What should have been explained is that "tortilla" is the Spanish word in Spain for an omelet. South Americans used it for another dish.

Do you think I can double this and cook in a big 13-inch cast iron skillet? Trying to feed 12 people for brunch.

If you double it in an 13-inch pan, it will be quite thick. I'd either do 10-inch pans or a 13-inch and an 8-inch. I hope this is helpful!

Amanda is wrong, yes you can use a large pan if you are doing to traditional way of making a traditional Spanish tortilla. We have seen beautiful, large tortillas in many cafes & restaurants all over Spain, and I cook one every Sunday for my 4 boys. Just make sure to flip it a bunch of times.

I only said large but wasn't specific about the diameter. I'd aim for a 10-inch pan.

Spaniard here. I don't really get the comment from "Pokolik". First up, there are as many ways of cooking a tortilla de patatas as families are in Spain. For example, my mother doesn't boil the potatoes, she fries them with onion and green pepper, (she even adds some chorizo). But my best friends boils it, and so on...

The fact that the recipe calls for an oven bake instead of frying in the pan, makes a lot of sense, because it is easier & less complicated than turning the tortilla with the help of a plate...

The fact is that this tortilla looks DELISH... and it is great to see so many people from other countries doing their own version.

To my mind, forthright criticism is the best way to go. Ir we demand others be "constructive" and "polite," then we fail to read the real truth.

I made a "frittata style tortilla" this morning and *steamed* the potatoes after slicing them instead of boiling before slicing. It was very quick and a nice trick if you need to save a little time, or are addicted to your steamer.
