  1. Put the spinach in a large colander and pour over a kettleful of boiling water. Drain well and, when cooled a little, squeeze dry, trying not to mush up the spinach too much.

  2. Heat 3 tbsp oil in a 25cm non-stick pan with a lid, then sweat the onions for 15 mins until really soft but not coloured. Add another 3 tbsp oil and add the potatoes and garlic. Mix in with the onions, season well, cover and cook over a gentle heat for another 15 mins or so until the potatoes are very tender. Stir occasionally to stop them catching.

  3. Whisk the eggs in a large bowl, tip in the cooked potato and onion, and mix together. Separate the spinach clumps, add to the mix and fold through, trying not to break up the potato too much.

  4. Add 2 tbsp more oil to the pan and pour in the sweet potato and egg mix. Cover and cook over a low-medium heat for 20 mins until the base and sides are golden brown and the centre has mostly set. Run a palette knife around the sides to stop it from sticking. 5 To turn the tortilla over, put a plate face down onto the pan, then flip it over. Slide the tortilla back into the pan and cook for a further 5-10 mins until just set and golden all over. (Don’t worry if it breaks up a little on the edges as you’re turning it – it will look perfect when it’s cooked through and set.) Continue cooking on the other side until just set and golden all over. Again use a palette knife to release the tortilla from the sides. Allow to rest for 5 mins, then tip onto a board before cutting into wedges.

Made this the night before for a picnic, absolutely delicious. As previously mentioned, does not need 15 mins of onion cooking and for that size of pan, I used 5 eggs and 3 medium sweet pots. You could skip the onion part and just use granuals. I also added garlic granuals as couldn't be bothered with any more slicing plus some smoked paprika. Post flip, 7 mins was perfect.

The quantities are way too big for a 25cm pan. I had trouble cooking the potato because there's was too much in the pan to cook it evenly. I should have gone with my gut and only used half the quantity. I had to add extra egg to cover the mix. There was also no way it was getting flipped so I finished it off in the oven. Also the cooking times seem really off; too long for the onion, not long enough for the potato. Too long before you flip. All in all, not a great recipe to follow, particularly for novice cooks. If I make again I'll use about half of the ingredients.

Mine burnt on the bottom and was still raw on the top so I will be following the advice below and trying again by finishing it off in the oven. I did taste the sweet potato mixture and it tasted good so I will be persevering

Perfect. And this should keep for a few days in the fridge too. Will make for a good brunch :) This is something similar that I made. I think I feel more safe not having to flip the thing! http://muchadoaboutnoting.com/breakfast-frittata/

Tried this last night for dinner along side of grilled salmon and salad. The amount of sweet potato asked for was way too much. I used 2 large instead of 4 medium as called for. I will attempt this again although I will use only one large sweet potato, and add some nutmeg like a previous poster suggested. While the potato is cooking under cover it really needs to be watched it doesn't overcook, as it gets starchy.

Does not take that long to cook! I thought it seemed much longer than the usual cooking time for omelettes, but perhaps the potatoes needed longer? Nope! My tea is now completely burnt on the bottom. I only left it for 10 mins, top was cooked too. Next time I'll just trust my gut!

This was a lovely tortilla. I would recommend using either a very large frying pan or two smaller ones as it is really huge! It does need seasoning well and I also added some grated nutmeg to the spinach. For the last part of cooking, I found that it started to catch in the middle after 10 minutes even though the heat was very low so I transferred it under a medium grill to finish cooking which took about 10 more minutes. If you press down with a fish slice any gooey bits should rise to the surface. When this stops happening, the tortilla should be cooked. It looked very attractive when sliced up. Served with smoked salmon, mixed salad and crusty bread.

This recipe is simple and delish. I used two small frypans and it made it easier to flip..Will make again for sure

What is the difference if instead the finished mixture is placed in an oven to avoid the flipping part?
13th Aug, 2014
No difference - sometimes when I'm using a sub-par frying pan I just grill the top in the oven (being mindful of the plastic handle) instead of flipping. Will be slightly different texture, but not affect the taste.

Has anyone frozen this?

No, unfortunately an egg dish like this with a high proportion of vegetable won't freeze well. It can be made a couple of days ahead and served cold or warmed in a low oven covered with foil if you want to get ahead though. Hope this helps

Is this something that could be frozen and defrosted as a part of batch cooking?

Hi there. You could also finish this in the oven instead.
