This tortilla de patatas is the classic Spanish omelette, and it’s one of my favourite simple dishes to cook at home. If you’re curious about where this humble dish sits in Spanish food culture, the Tortilla de Patatas even has a surprisingly detailed entry on Wikipedia.
If you've ever wondered about the difference between a tortilla, a frittata, and an omelette, I've written about that too.
In most Spanish households, this national dish consists of eggs, potatoes, onions, olive oil, and salt. My version is no different, except that I add grated cheddar cheese and a pinch of black pepper.
The addition of cheese gives it more luxury and oomph, much to the disdain of my neighbour, who turned her nose up at the thought of adding cheddar. I stand by it — it works.
How to Make a Tortilla de Patatas
Fresh ingredients for a homemade Spanish omelette (tortilla española), including eggs, potatoes, onions, olive oil, and seasoning, arranged on a kitchen prep board.
Beat the eggs in a bowl with a pinch of black pepper. Add the grated cheddar and mix well.
I cook this the traditional way, in plenty of good olive oil — and if you’re curious about the kind I use at home, I’ve written about my favourite unfiltered organic extra virgin olive oil here, including why this type of oil elevates Spanish cooking.
Fry a thinly sliced onion with a pinch of salt until caramelised, then set aside.
In the same pan, fry the sliced potatoes for 15–20 minutes or until they start to break up.
Add back the onions and gently mix.
Pour the egg and cheese mixture over the potatoes and onion, shaking the pan to spread everything evenly.
Cook on low for 10 minutes before flipping (I use a plate for this) and continue to cook for another 5 minutes or so.
I use a silicone spatula around the edge to stop the tortilla from sticking.
When done, allow this Tortilla de Patatas to stand for a few minutes to set.
Serve warm with a salad.
This is served as a tapa in my village. I like it warm or at room temperature, but straight from the fridge does nothing for me.
Tips for the Perfect Spanish Omelette
It’s crucial to cook your tortilla on low heat to prevent it from becoming rubbery. Slow and gentle cooking keeps the eggs tender and lets the flavours meld beautifully.
My late Mum, bless her heart, used to make what she called a “Spanish” omelette. Unfortunately, it consisted only of eggs, and the result was often rubbery and unappetising. While her effort was genuine, it lacked the nuances of a true Tortilla de Patatas — a reminder that technique and patience make all the difference.

FAQ – Tortilla de Patatas (Spanish Omelette)
What is tortilla de patatas?
Tortilla de patatas is a traditional Spanish omelette made with potatoes, onions, eggs, and plenty of good olive oil. It’s a simple, comforting dish served across Spain.
Should tortilla de patatas include onions?
This is a classic debate. I prefer it with onions because they add sweetness and depth, but you can leave them out if you like.
What kind of potatoes work best?
Waxy potatoes hold their shape and give the tortilla a creamy texture, but any potato you have at home will work.
Can I make tortilla de patatas without flipping it?
Yes. If flipping feels tricky, you can finish the top under a grill. Flipping is traditional, but both methods work well.
Why use unfiltered extra virgin olive oil?
Unfiltered extra virgin olive oil brings richer flavour and a more authentic Spanish character to the dish, enhancing the overall taste.
Can I add cheese to tortilla de patatas?
Yes. A handful of grated cheddar melts into the eggs and adds a delicious savoury twist.
How do I know when the tortilla is cooked?
The edges should be set and lightly golden, while the centre stays soft and custardy. Cook it longer if you prefer a firmer texture.
Is tortilla de patatas served hot or cold?
Both are traditional. Warm is comforting, but cold tortilla is perfect for tapas, picnics, and next‑day snacking.
How long does tortilla de patatas keep?
It keeps well in the fridge for up to 2 days. Enjoy it cold or gently reheat it in a pan.
