  • 6 large egg


  1. Heat oven to 200C/180C fan/gas 6. Using a large frying pan, soften the onions with 1 tbsp olive oil and some seasoning. Cook over a low heat for 20 mins or until golden and caramelised.

  2. Place the potato slices, 3 tbsp olive oil and seasoning onto a large baking tray or 2 small ones and toss them around. Bake for 15 mins until potatoes are soft, but not brown.

  3. Mix the eggs in a large bowl with more seasoning. When the potatoes and onions are done, toss them in and mix well. Add the remaining 1 tbsp oil to a 20cm frying pan, warm it and pour in the egg mixture. Allow to cook slowly over a low heat for 20-25 mins.

  4. When nearly all the liquid egg is gone, you will need to flip it over. Place a plate on top of the pan and invert the tortilla, holding the plate firmly while doing so. Slide the tortilla back into the pan and cook for another 3-4 mins. Alternatively, if you aren’t too confident about flipping and your pan is ovenproof, place the pan under the grill for a few mins until the top is done. Serve cut into wedges, warm or at room temperature.

To Jills Fills, Res-eeps and Mike. You're all right- 2.5cm slices of potato was an error on our part. Our cookery team suggest you slice thinly according to personal taste and depth of pan. Sorry for the mix up! All the best, BBC Good Food web team.

I can guarantee you that it isn't 2.5cm! Think it might be easier to go for half an inch (at the most).

I think this recipe is missing something i.e. herbs, or a sauce of some kind.

Probably not one I'd make again.

It surely means 2.5mm -- though that's awfully specific!

Suggest that 2.5 cm slices are a little larger than the picture suggests!
