    • 100g natural yogurt
    • 4 tbsp semi-skimmed milk

    Method

    1. Slice the onions into small, thin, wedge-shaped pieces. Heat the rapeseed oil in a large, preferably non-stick, sauté or deep frying pan. Stir in the onions and fry over a medium heat for about 20 mins. Stir only occasionally so they can cook fairly undisturbed and caramelise underneath. When done, they should be well caramelised and sticky.

    2. Meanwhile, prepare the base. Heat oven to 190C/170C fan/gas 5 and put in a baking sheet. Put the flour and butter in a bowl with a pinch of salt and rub with your fingers until it resembles rough crumbs. Mix the yogurt and milk, pour it into the flour mixture and work together briefly with a knife until the dough just comes together. Remove from the bowl and gently press together to form a ball. Do not overwork the mixture.

    3. Roll dough out thinly on a lightly floured surface and use to line a 23cm round, fluted, loose-based flan tin, about 2.5cm depth, pressing it with your fingers into the flutes. Sit the tin on. If the dough is a little sticky, dust your fingers in some flour.

    4. Beat the eggs in a medium bowl, then stir in the crème fraîche, thyme, mustard and seasoning. Spoon and spread half of the onions into the lined base, season with pepper then scatter over half the cheese. Pour the egg mixture over the top, then scatter over the rest of the onions and cheese. Sit the tin on the hot baking sheet and bake for 25-30 mins until the base and filling are cooked. Remove and cool for about 10 mins, then remove from the tin and serve while fresh and warm.

    I don't really like quiche, except those Higgidy ones, so took a bit of a chance with making this and it was lovely! Served with roasted new potatoes, homemade olive oil bread and a rocket and tomato salad with balsamic. I only had a 23cm springform tin so I used that, and just pushed the pastry into the tin without rolling. I added slightly more mustard and cheese, and think it was spot on for my tastes, although I did let it cook for a little longer. Will definitely make again and would try adding smoked bacon, or maybe feta and roasted red peppers instead of gruyere.

    As someone else has asked, could either creme fraiche OR yoghurt could be used for both filling and pastry? As they can only sit in the fridge for 3 days, it does mean having to plan specific meals to use them up....unless the cooked quiche could be frozen, so you could make 2 and then freeze one?

    A simple delicious recipe! I substitued white onions for red onions since I didn't have any red ones and it was still great. I followed the previous tip about using the sheets of cling film to roll the pastry which worked very well.

    I love this recipe! I do tend to burn the onions slightly every time I make it but it always turns out nice. Never bother rolling the pasty, I just tend to squish it into the tin. It does stick to your hands so flour them liberally. I am just waiting for a slightly adapted tart to come out of the oven (red onion, spinach and goats cheese). We'll see if it as nice as the original recipe :)

    I've just taken this out of the oven and it smells great. I can't wait to try it! I didn't use the pastry recipe given as I had no yogurt but I'll try it next time. I used a little more cheese than the recipe stated as several people had said there was not enough in the original recipe but if it tastes as good as it smells it'll be a winner.

    Lovely & easy to make , adding the yougurt to the base made it very quick to work and easier to roll .we all enjoyed it with a nice salad ! Added a bit more salt and pepper and doubled the amount of cheese to give it more taste .will definetly make again and use the same base for other tarts!

    Really nice recipe, was surprised at how quick and easy it was! Like someone before me I didn't roll the pastry out, just pressed it out into the tin with my fingers, and it turned out lovely! Going to make it again at Christmas for the family.

    This looks really yummy, looking forward to trying it when I can get the ingredients. Would it work putting extra crème fraîche in the pastry instead of the yogurt as I'd rather not have to buy both especially for this?

    The texture was lovely, but did not find it that flavoursome- maybe more mustard was needed? Looks great though!

    You would never know this was a healthy option as yummy! Although I did add a bit of grated parmesan on top too. Served up the next day as part of a beach picnic and everyone ate it all up. The 'taste the difference' one part went in the bin.

    I hate making pastry so this scone base appealed to me, it was an easy to make quiche but took me longer than 25 mins. The middle was so creamy and tasty and went well with the scone base, tasted even better the next day for lunch, will definitely make again.

    Made this last night and we both really enjoyed it, only change I made was using double the amount of cheese, and glad I did. having leftovers for lunch with salad on Monday. Initally thought yogurt a strange addition to the pastry base but it turned out great. This was a definate hit, will make again.

    Lovely tart, really delicious and the base is really tasty. Was a nightmare trying to roll it out though and ended up just shaping it out in the tin with my hands instead, which worked perfectly - would recommend others to do the same as it will save a lot of mess!

    Just made this with gluten free pastry (frozen - DS make it and most big supermarkets stock it) and it was delicious! My boyfriend is looking forward to having it again for lunch tomorrow.

    This went down a treat with my family. I roll out the pastry in between 2 sheets of cling film. That way it doesn't crack, you can get it really thin and don't need any extra flour.

    Thia was really delicious - even my meat loving husband enjoyed it! It would be great served as part of a summer buffet.

    I loved this quiche but made a bit of a variation with what i had in the fridge, I used ready rolled pastry and baked it blind, used leftover brie sliced and put in where the cheese is added, next time i make it id do more onions and also I needed more of the egg mixture.

    Very yummy. The whole family enjoyed it. My base was sticky and hard to roll out, but i am awful at pastry, so i ended up prodding into the dish, but turned out lovely.

    I was happy with the end result, but I found it hard to make the scone case. Would make again however, the leftovers lasted me for a few days in lunches!

    Made this for dinner tonight and it was delicious. I used two large eggs by accident and it was fine. Wolfed down by the whole family and I have leftovers for lunch tomorrow.

    This was ok, but I found it a bit sweet. We love the ultimate makeover quiche, but found this a bit disappointing. Will not bother to make again.
