  1. Scrape 500g new potatoes or leave the skins on, if you prefer. Cut them into thick slices. Chop 1 onion.

  2. Heat 150ml extra-virgin olive oil in a large frying pan, add the potatoes and onion and stew gently, partially covered, for 30 minutes, stirring occasionally until the potatoes are softened. Strain the potatoes and onion through a colander into a large bowl (set the strained oil aside).

  3. Beat 6 eggs separately, then stir into the potatoes with 3 tbsp chopped flat-leaf parsley and plenty of salt and pepper. Heat a little of the strained oil in a smaller pan.

  4. Tip everything into the pan and cook on a moderate heat, using a spatula to shape the omelette into a cushion.

  5. When almost set, invert on a plate and slide back into the pan and cook a few more minutes. 

  6. Invert twice more, cooking the omelette briefly each time and pressing the edges to keep the cushion shape. Slide on to a plate and cool for 10 minutes before serving.

I made a mini version of this using a small fried egg pan. 1 red potato, half a small onion and 2 eggs. I did everything the recipe said just with smaller amounts of ingredients and the result was a perfect little Spanish omelette for one. I will definitely make it again.

The recipe was pleasant enough but the ratio of potatoes to eggs was too high. Next time I will use at least one extra egg, or maybe two, and I will also slice the potatoes more thinly. The instructions worked well though and I will definitely make more Spanish Omelettes

So yummy I loved it. It comes out massive. I made it for me and my pal and there’s enough left to have some for lunch tomorrow which is a result.

My late mother lived in Spain for a few years. That is more or less how she made this type of omelette, and they were very good.

Very tasty indeed, I had a bit of trouble inverting the omelette onto a plate from the frying pan as my hands are a bit arthritic but I persevered! I served it with a bean salad.

My potatoes went a grey colour. Where did I go wrong.

This was my first attempt at a Spanish omelette. I halved the recipe and it was a perfect snack for 3 people. A few mistakes I made: I started the potatoes and onions off on a medium sized ring on my gas cooker and they fried too quickly in the first five minutes. I switched to the smallest just in time but some of the onions had too much colour by the end of the 30 mins. Next time I will use the gentlest heat from the start. Also I used mixed size eggs and should've added an extra one. Tasted amazing though. So comforting and indulgent. Will. Make it again and again!

I would probably skip the parsley, but otherwise a fairly accurate recipe for Tortilla Española.

Thanks for your question. This makes 4 portions but you can cut into smaller pieces to make it go further if serving alongside other dishes.

It was very good. Withholding a star because of my usual complaint: quantities are not clear. Onion sizes vary greatly. It would be more helpful to give a volume of chopped onion. And eggs: medium, large, extra large? "Plenty" of salt equals how many tsp? More salt than I used, probably because of the potatoes. Pans: diameter of "large" and "smaller"? How about a half tsp of crushed garlic? Or less, perhaps: enough to hint garlic, not enough to shout "GARLIC!". Thanks.

Thanks for your feedback. We specify exact sizes when it's key to the success of the recipe, otherwise we keep things loose, enabling people to use what they have in the way of ingredients and equipment. Sometimes, it's a question of taste too. We're glad to hear the recipe turned out well nonetheless.

I was worried about the omelette breaking when sliding into the pan so I used two plates. Place the first plate over the omelette in the pan and turn. Place the second plate over the first plate and turn. Now place the pan over the second plate and turn. Make sure your hands aren't oily when turning the plates! I added rosemary. It turned out perfectly.
