Spanish Tortilla (Tortilla de Patatas): the Recipe for a Tortilla Ready in Less Than 30 Minutes!

The Spanish Tortilla, or tortilla de patatas, is a typical specialty of Spanish cuisine. It is a sort of potato omelette, thicker and tastier, made with potatoes cut into thick slices, beaten eggs and onion. It often takes on the appearance of a cake – as for example in the iconic tortilla served in Cordoba in the Santos bar – because it can reach several centimeters in height depending on the pan in which it is cooked and based on the number of eggs used. It can be consumed hot as an appetizer, or even a main dish, but also cold, as a tapas-style brunch: in Spain, in fact, it is enjoyed in any bar or restaurant at any time of the day.

To prepare a good tortilla, the potatoes are not boiled but fried gently together with the onions, until they are colored but soft. Then they get smashed a bit and drained well of the excess oil and added to the beaten eggs before proceeding to be cooked in a pan like a classic omelette.

What is Spanish Tortilla?

Tortilla de patatas (pronounced tor-TEE-yah deh pah-TAH-tas), also known as Spanish omelette, is a traditional dish from Spain. Its origins are somewhat disputed, but it's widely believed to have been created in the early 19th century. One popular legend suggests it was first made during the Carlist Wars by a Carlist general who needed a simple, nutritious dish to feed his troops. The basic recipe includes eggs, potatoes, and onions, though variations exist. Over time, tortilla de patatas has become a staple in Spanish cuisine, enjoyed in homes, bars, and restaurants across the country.

Tips for the Best Spanish Tortilla

• Ensure that the onion and potatoes are sliced into even circles. This helps them cook evenly and ensures a uniform texture in the final dish.
• You can soak the onions in lightly salted water to make them more delicate, or you can replace the white onion with the red one, if you prefer.
• Don't skimp on the oil when frying the potatoes and onions. They should be well-submerged to cook properly and achieve the right texture. The excess oil can be strained off later.
• Fry the potatoes and onions on medium-low heat to allow them to cook gently and fall apart without burning.
• After frying, make sure to drain the potatoes and onions thoroughly to remove excess oil. This step is crucial to avoid a greasy tortilla.
• Let the potatoes and onions cool before adding them to the beaten eggs, to prevent the heat from curdling them.
• Whisk the eggs until they are well combined and slightly frothy. This will add air to the mixture, making the tortilla lighter.
• Don’t be shy with the salt. Potatoes absorb a lot of seasoning, so make sure to season the egg mixture adequately.
• When cooking the tortilla, use medium heat. This ensures the outside doesn’t burn while the inside cooks through.
• Use a plate to help you flip the tortilla. Place the plate over the pan, hold it tightly, and flip the pan so the tortilla lands on the plate. Then slide it back into the pan to cook the other side.

Are Frittata and Tortilla the Same Thing?

The Spanish tortilla, or tortilla de patatas, traditionally includes potatoes and onions and is cooked on the stovetop, often flipped to cook both sides evenly. It's thicker and denser, typically served at room temperature. On the other hand, the Italian frittata is more versatile in its ingredients, often including cheese and a variety of vegetables or meats. It starts cooking on the stovetop but is finished in the oven, creating a lighter, fluffier texture.

Are Tortillas and Spanish Tortillas the Same Thing?

No, tortillas and Spanish tortillas are not the same thing. In many parts of the world, tortillas refer to thin, flatbreads made from corn or wheat, commonly used in Mexican cuisine for dishes like tacos and burritos. Spanish tortillas, or tortilla de patatas, are a thick omelette made with eggs, potatoes, and sometimes onions, originating from Spain.

Why Is My Spanish Tortilla Greasy?

Maybe you didn't drain the potatoes and onions thoroughly after frying them. When the two retain too much oil, this will mix with the eggs, and result in a greasy texture.

Can I Bake This Spanish Tortilla?

Yes, you can! Preheat your oven around 350°F (175°C), pour the mixture into an oven-safe dish and bake for about 20-25 minutes, or until the tortilla is set and golden on top.

What Are the Best Potatoes to Use For The Spanish Tortilla?

The best types of potatoes to use are starchy varieties like Russets or Yukon Golds which break down more easily during frying, creating a soft, cohesive texture that is ideal for the dish. Yukon Golds, in particular, offer a slightly buttery flavor that complements the eggs and onions nicely. Their creamy texture helps bind the tortilla, ensuring it holds together well while remaining tender and flavorful.

Can I Add Other Ingredients to The Spanish Tortilla?

Yes, you can! Common additions include bell peppers, chorizo, spinach, and cheese. Bell peppers provide a sweet crunch, while chorizo adds a smoky, spicy depth. Spinach introduces a fresh, earthy note, and cheese can offer a creamy, melted richness.

What Can I Serve With Spanish Tortilla?

A fresh green salad with a light vinaigrette adds a crisp contrast to the rich, hearty texture of the tortilla. For a more traditional touch, you might serve it with pan con tomate, which is toasted bread rubbed with ripe tomatoes and drizzled with olive oil. A side of roasted red peppers or a simple plate of olives and manchego cheese can also enhance the flavors. Additionally, a glass of chilled white wine or a light red can round out the meal perfectly.
