Spanish Omelette

A Spanish omelette - or tortilla española if you want to be authentic about it - is one of those deceptively simple dishes that requires a little patience to get right.

It's been a staple of our family picnics for years. So much so that it became the designated dish I'd instruct my sister to make - which, more often than not, resulted in a dramatically burnt bottom! The secret, as it turns out, is to cook the omelette low and slow. Rush it and the eggs overcook. Give it time and you get that perfectly set omelette with a beautiful golden crust.

Beyond picnics, a proper tortilla española is an essential on any good tapas menu - the kind of thing you order without thinking at a Spanish bar and immediately wonder why you don't make it more often at home. Serve it warm or at room temperature, sliced into wedges with a dollop of aioli alongside and a fresh Greek salad - suddenly a Tuesday lunch feels considerably more civilised!

Why You'll Love This Recipe

Five ingredients, endlessly versatile

Eggs, potatoes, onion, olive oil and salt - that's it. The simplicity is the point. A proper tortilla española doesn't need anything else and the result is far greater than the sum of its parts.

Perfect hot or cold

Serve it warm straight from the pan or at room temperature - it's equally delicious either way. Makes it brilliant for picnics, packed lunches, tapas nights or a quick light lunch.

The low and slow secret

This is not a recipe to rush. Cooking the potatoes gently in olive oil and keeping the heat low for the omelette itself is what gives you that perfectly set, slightly yielding centre rather than rubbery overcooked eggs. Patience is the ingredient nobody mentions.

Great for a tapas night

A tortilla española is the cornerstone of any good tapas spread. Serve alongside patatas bravas, olives, cured meats and some good bread for a proper Spanish feast at home.

Brilliant for using up eggs

Six eggs, a couple of potatoes and an onion - the kind of fridge staple meal that costs almost nothing and tastes like something from a restaurant.

Serve it the Spanish way

Slightly warm, sliced into wedges with a generous dollop of aioli alongside. A simple green salad on the side makes it a proper light lunch that feels like a little holiday.

4 Servings 50 Minutes

Ingredients

Eggs - 6
Olive Oil - 3 tbsp
Salt - 1 tsp
Brown Onion - 1
New Potatoes - 400 grams

Method

Peel and slice potatoes into thin rounds (about 3–4 mm thick), then peel and thinly slice the onion.
Heat 2 tbsp olive oil in a large non-stick frying pan over medium-low heat. Add the potatoes and onion, stir to coat in oil, then reduce heat to low. Cover and cook gently for 15–20 minutes, stirring occasionally, until potatoes are tender but not browned. Season lightly with salt.
Remove the potato and onion mixture from the pan and set aside in a bowl. Wash the pan and return to the heat.
In a large bowl, beat the eggs with a pinch of salt. Add the potato and onion mixture to the eggs and stir gently to combine without breaking up the potatoes too much.
Heat the remaining 1 tbsp olive oil in the frying pan over medium heat. Pour in the egg and potato mixture and spread evenly. Cook gently for about 5–6 minutes until the bottom is golden and the edges are set but the centre is still a little runny.
Place a large plate over the pan, hold it firmly, and flip the omelette onto the plate. Then carefully slide the omelette back into the pan to cook the other side for 3–4 minutes until just set in the centre.
Once cooked, transfer to a plate and let it cool slightly before slicing into wedges. Serve warm or at room temperature.

Hints and Tips

Low and slow is non-negotiable

This is the most important tip. Cook the potatoes on the lowest heat possible - you want them tender, not browned. And when the egg mixture goes in, resist the urge to turn up the heat. Low and slow is what gives you a perfect tortilla rather than a burnt one. Ask my sister.

Don't break up the potatoes

When you stir the potato and onion mixture into the beaten eggs, do it gently. You want the potato slices to stay relatively intact - they give the tortilla its characteristic layered look and texture.

The flip is the moment of truth

Place a large plate firmly over the pan, take a breath, and flip confidently in one smooth motion. Hesitate and it goes wrong. A wide, heavy plate works better than a small one - you want it to cover the whole pan.

Use a good non-stick pan

This is not the moment for your worst pan. A good non-stick is essential for getting the tortilla out cleanly and for achieving that golden crust without sticking.

Slightly runny in the middle is correct

A properly made tortilla española should be just set in the centre with a tiny bit of wobble - not completely solid. If it's fully cooked through it's been on too long. The residual heat will finish it off as it rests.

Rest before slicing

Let it cool for a few minutes before cutting into wedges. It holds together much better when slightly cooled and the flavours settle beautifully.
