Sometimes you can’t beat a homemade quiche with a baked potato and a nice fresh salad, but it always takes me longer to make a quiche than I think it will! Which is why I was very excited to ‘discover’ this amazing (magic?) crustless quiche. The Aussies call it ‘impossible quiche’! Read on to find out why, and how to make it…
All quiches are easy to make… right?
A big thumbs down for traditional homemade quiche!
Whenever I make quiche, which we all enjoy in our family (including our super picky toddler!), I find it surprisingly time consuming to make.
I also find the end result varies.
I’m sure it’s just me, but I often end up with holes in my pastry (aka half the filling dripping out onto the oven – oops. See this post. Delicious quiche, terrible photos desperately in need of an update!).
Or I undercook or overcook the filling.
Even if everything goes swimmingly and my quiche is perfect, it takes ti-iiiiii-me. Especially if I make my own pastry.
So now… I either make THESE mini quiche lorraine, because you don’t have to precook the pastry or fillings, or I make THIS crustless quiche.
Impossible Quiche!
Have you ever heard of impossible quiche? I’ve only ever seen recipes for it in Australia, but it’s pretty well known there, and for good reason. It’s a delicious quiche – and a little bit different!
Most crustless quiche recipes I find a bit too interchangeable with a frittata. The thing that makes this recipe different is that you add flour to the egg mixture.
The idea is that the flour sinks to the bottom of the quiche during cooking and makes a very light ‘crust’.
Quiche or souffle?
I say crust, but really I’d describe it as a sort of pancake-y layer that’s slightly heavier than the rest of the quiche. Sometimes it’s a bit more defined than other times.
I think it might depend of the type of fillings that you add to the quiche, and whether or not they are cooked.
Either way the quiche is delicious. If the flour doesn’t sink so much, I find that the eggy mixture has a slightly different texture to a regular quiche – almost like a souffle! The top of the quiche is also a bit crunchier than usual. As some of the flour stays on the top, it forms a kind of light batter topping.
This quiche reheats really well, and when you reheat it the top gets even more deliciously crunchy. Try it and see!
Erm… but what’s Impossible Quiche?
If I’m totally honest I don’t know why this is called impossible quiche. At first I thought it was because of the thin ‘crust’ that forms at the bottom, as if by magic!
But this feature of the quiche is subtle, and like I said before seems to depend on what fillings you’ve added.
So maybe it’s because the quiche is ‘impossibly’ quick to make?
Lightly cook the onions and mushrooms (or whatever fillings you want to add), then pour everything into your quiche pan and cook it for just 30 minutes.
Caramelizing the onions. Mmmm, delicious!
Before…
After…
Of course it doesn’t really matter why it’s called what it’s called. The important thing is that it’s a really delicious quiche. Recently it’s become my go-to, and I wonder if it will become yours too if you give it a go!
Why is this the best crustless quiche?
To summarize, I think this is the very best crustless quiche because…
- It’s REALLY quick and easy to make, but it ISN’T just another frittata!
- It seems really cheesy, even though there isn’t that much cheese in it – almost like a souffle.
- This particular quiche is made with ham (so no pre-cooking!), mushrooms, and the most amazing caramelized onions.
- If you’re lucky there’s a kind of magic thin crust on the bottom of your quiche.
- Sometimes, when I’m feeling especially lazy or short on time, I don’t pre-cook any of the veggies. I just add finely chopped onions, peppers and chopped cherry tomatoes (as well as ham and cheese, of course!). Surprisingly I seem to end up with the best ‘magic crust’ on the bottom of the quiche when I do this.
- You use milk to make this quiche, not cream. So it’s a little lighter than a regular quiche – but no less delicious!
- This crustless quiche reheats really well. If anything it’s more delicious when reheated!
So next time you’re craving a quiche, I challenge you to ditch your regular recipe (or store-bought go-to!) and give this crustless quiche a chance.
What to serve with a crustless quiche
Our favourite way to eat quiche is with a baked potato and salad. Don’t forget the coleslaw – trust me, it’s the icing on the cake 😉
Another easy quiche recipe for you!
If you’re loving the easy quiche vibe in the post, but would rather keep the crust…
- try these easy mini quiche lorraine! They do have pastry, but you don’t need to pre-cook it. In fact you don’t pre-cook anything. The quiches are super super quick and easy, contain only 6 ingredients, and are perfect for freezing and/or taking along to parties!

Notes
A note on the fillings
The amount/type of fillings in this recipe are just a guideline. You could easily make a more traditional quiche lorraine with just bacon, onions and cheese if you prefer. To make this quiche even quicker and easier, don’t pre-cook a single thing! I’ve made it with just finely chopped raw onion and peppers, halved cherry tomatoes, and lots of cheese! Interestingly, this made for the best ‘magic crust’ on the bottom. Or add things like: leftover cooked roasted vegetables (I often add these)asparagus (no need to pre-cook)
chopped spinach (blanched and squeezed) & cubes of feta cheese
Ellie says
Maybe I should have cooked the mushrooms more before adding to the baking pan. They weeped and when I cut into the quiche, moisture seeped out. Other than that the taste was very good.
Helen says
Hi Ellie! Yes, I do usually cook the mushrooms for a few minutes before adding them to the quiche pan. Try that next time and see how you get on!
Helen says
Hi Helen, if I make this quiche in the morning will I have to take it out of the flan dish to reheat later or can I reheat it in the dish. What temperature and how long would you reheat it? Thanks Helen
Helen says
Hello Helen! (great name!) You can absolutely make this ahead and reheat again later in the flan dish. If you want to reheat the whole quiche again, start with around 20 minutes in the oven at 300F/150C and go from there. If it isn’t quite reheated at that point, give it another 5 minutes until it’s piping hot again. Enjoy!
Helen says
Many thanks for replying back to me!!! That’s great I’m actually going to make it in a hour’s time ready for dinner tonight!! I’m so looking forward to trying it!!!😄. I’m serving it will salad and some sweet potato fries. Kind regards Helen xxx P.S yes it is fab name🤣🤣🤣
Helen says
I hope it turned out well and you enjoyed it, Helen! Salad and sweet potato fries sounds perfect 🙂
Helen says
Hi Helen, just to let you know the quiche was absolutely fabulous!!! We all loved it and i will definitely make it again!!!! My family said no more shop bought quiches when they can have this🤣😄😄😄. Many thanks Helen (UK)
Helen says
Ahhh, so good to hear that, Helen! Thank you so much for keeping me updated – I love it!
Jens says
I have made it 4 or 5 times now, and it is a winner. Thanks for sharing!!
Helen says
Hello Jens. That makes me sooo happy to hear that this is a winner in your house! Thank you so much for the feedback.
Ngaere Farquhar says
Made this last weekend and so good I used leeks instead of onions , carrots and small amount silver beets (all out of my garden) and mushrooms,,I only had 3 no 8 eggs but the thing I liked most was self crusting so quick and easy. Will definitely being making it again and I had it with a lettuce salad.on the side. What I didn’t use put in the freezer. Will make sure I use correct amount of eggs next time.. I think this will be a regular light healthy meal for me
Helen says
Thank you so much for the lovely review, Ngaere – you know how much I appreciate it! I love that you were able to use so much homegrown produce – definitely making me envious. I’m glad you freezed some for another time. I often do that since it’s a pretty big quiche. 🙂
Kim says
Had my doubts but used the 9 inch loose-bottomed quiche pan as instructed and everything leaked out the bottom! Complete waste of time. Should have looked at the photos more carefully as NO LOOSE BOTTOMED quiche pan used there
Amend your recipe please
Kim
Helen says
Hi Kim, sorry to hear this happened to you. I know how frustrating it feels to waste all your ingredients. Loose-bottomed pans should be watertight (but obviously they aren’t always), or you can tightly wrap foil around it just in case, but I’ll remove that link from the equipment section so that doesn’t happen to anyone else. I hope you’ll give the quiche a second chance and make it in a regular quiche pan.
Lesley says
Will this work with gluten free flour…keen to try it 😄
Helen says
Hello Lesley! Yes, gluten free flour will be fine. The results may be a little different but it will definitely still work. Enjoy! 🙂
Ted says
As asparagus is in season I substituted it for mushrooms and made another successful quiche
Helen says
Hello Ted! I’m so happy you like this enough to keep trying it different ways. I’m so happy asparagus season is here again, and love the sound of your mushroom asparagus quiche. Thank you for the idea – I’d love to try it that way! 🙂
Ted says
Hi Helen ham and asparagus is what I used Ted
Helen says
Mmm sounds wonderful Ted! I’ll try it since we’re just coming into asparagus season!
Hayley says
I love this recipe and have made it several times using different fillings! It’s usually a good way to use up random leftover veggies as a substantial meal if I’m in need of going shoppig. However I now need to be dairy free. Do you think it wouls still work if I use oat milk instead and have no cheese? I still can’t get my head around no cheese, it’s such an integrated part of my life!
Helen says
Hello Hayley! I’m so happy you’ve been enjoying this recipe, but equally sorry to hear that you’re dealing with having to change your diet in this way. I know that’s hard. Our son is allergic to nuts so we have to be careful about ingredients since they’re in many foods where you wouldn’t expect to find them (pesto etc.).
I actually think you’d be fine using oat milk or another type of dairy free milk to make this quiche. I haven’t tried it myself but after a quick google I can see that it is possible to make a dairy free quiche just by using dairy free milk and excluding the cheese. Can you get hold of some dairy free cheese? I know that it does exist but haven’t tried it myself. Can you tolerate goat or sheep’s milk cheese? There are some authentic feta cheeses made from those milks!
If you do decide to try the quiche diary free, I’d love to hear how you get on. Best wishes, Helen 🙂
Ollie says
Love love love this recipe.
Best ever.
Helen says
Aw, thank you Ollie! I’m so happy that you’re enjoying it! 🙂
Mary F Zoppa says
I don’t have self rising flour. I hate to buy it just for this recipe. Can I use another flour>
Helen says
Hello Mary! Yes, of course! Just mix half a teaspoon of baking powder into the half cup of flour called for in the recipe. Just use all-purpose/plain flour. If you have a quick scroll through the comments below the recipe, some readers have also successfully used other types of flour, but I’d stick to plain white flour if you have it. Good luck and I hope you enjoy it!
Mary F Zoppa says
I took your advice and added baking powder to all purpose flour. I doubled the recipe and added bacon and broccoli to the ham and mushrooms. I had small amounts of gruyere and sharp cheddar as well as parmesan-it was good! I will cut and freeze one quiche. for hubby’s lunch. I will spice it up more next time (there will be a next time-great recipe). I will probably add garlic powder, and cayenne, It is a keeper!!
Helen says
I love your ideas for making this recipe your own, Mary. Thank you so much for the great feedback! 🙂
Christine says
Hi Helen just wanted to say I made the quiche with the gluten free flour, Stilton, broccoli and cherry tomatoes and it was super, think it may have been a little lighter if ordinary flour had been used but nevertheless it’s a keeper and will be making it again.
Thanks,
Christine
Helen says
Ah this is so good to hear, Christine – thank you for letting me know and I love the sound of your stilton and broccoli version! 🙂
Maureen Macfarlane says
Thank you Helen for the amazing quiche recipe.I’ve just put another one in the oven , having made two previously. Both were a huge success. So easy. Cheers Maureen
Helen says
Hello Maureen! Aw, thank you so much for letting me know you enjoyed it! It’s always the biggest compliment when someone makes a recipe more than once. 🙂
Lynn says
Delicious! Better than traditional quiche (with crust). Thank you 🙂
Helen says
Thank you so much for the feedback, Lynn. I’m so glad you liked it!
Annie says
Hi, I intend making this quiche at the weekend.
What type of ham is it best to use? Thanks
Helen says
Hello Annie! It doesn’t really matter but for maximum flavor I’d choose a good quality, fairly thick cut off-the-bone smoked ham. But I’ve even made it with that thin stuff you buy in a packet for sandwiches! Enjoy!
Christine says
I’d like to make this for a friend who’s Gluten intolerant, could I use cornflour please?
Helen says
Hello Christine, yes that should be no problem at all. The cornflour may not combine to make a ‘base’ but the quiche will still have a lovely texture. Alternatively you can use gluten free flour. Good luck and I really hope your friend enjoys it!
Christine says
Thanks for that, stupid of me not to think about it especially as I have some in my cupboard!! Unfortunately all my quiche tins are perforated, I have a dish but it’s quite deep could the ingredients be increased don’t want it to look half full. Am going to try broccoli, Stilton and cherry tomato which is what they all like, must admit bit nervous about it!!!
Helen says
Not stupid at all, Christine! I think both will work. As for the tin, I think you could either line the quiche tin with 2 layers of baking paper, or you could increase all the ingredients by say 50% (there’s a slider in the recipe card if you’d like to use that) and use your larger dish. The cooking time will increase a bit but it’s pretty easy to see when the quiche is done. Just keep an eye on it. You want it to have started to brown on top (lightly) and for it to be ‘just’ set in the middle. Although saying that a few times I have slightly overcooked it and it’s still been delicious. Try not to be nervous – it’ll be delicious even if not perfect! 🙂
valda cox says
Hi there from Cape Town South Africa.
I really enjoyed this quiche and don’t think I will ever worry about making a pastry lining again.
I made a spinach, feta and cooked onion one and you don’t even miss the not having a pie crust.
I am going to send it to my daughter in the UK
Thanks
Helen says
Hello Valda, always love to hear from people from near and far. Would love to visit Cape Town some day! I hear it’s beautiful. I’m so happy you enjoyed the quiche, and I love the sound of the way you made it your own. I agree that you just don’t need the crust any more, and I really hope your daughter likes it too! 🙂
Rodney says
Lekke… we are NOW busy making 2 this for dinner and leftovers for breakfast tomorrow morning (if anything will be left).
Greetings from Kuilsriver, Cape town South Africa.
Helen says
Hello Rodney! I hope you enjoyed it! Love the idea of finishing off for brekkie! Lekke! 🙂
Adriana says
It’s called impossible quiche (or sometimes impossible pie), because it’s virtually impossible to mess it up 🙂
Helen says
Oh I love that, Adriana! Thank you for the reminder and I hope you liked the recipe 🙂
Pat Scott says
The best tasting crustless quiche I’ve made!!
Helen says
So great to hear, Pat! Thank you for the feedback 🙂
Reggie says
Wow! The best I’ve tried so far. The mustard seed just makes it sing!! I’ve made this many times and tweaked it many times, they were all nice but the original recipe is the best!
Helen says
Thank you so much for the vote of confidence, Reggie – I really appreciate you taking the time to leave a great review. Like you I’ve made many different versions of this, but always come back to the original 😉
Desiree says
I have made this a few times and it always comes out delicious. I now bake it ahead of time and freeze it for lunches.
Helen says
Hi Desiree! I’m so happy that this has become a favourite recipe! And it’s very helpful to hear that you find it freezes well. Thank you so much! 🙂
DG says
I spiced up with red chili peppers sautéed with ham and onion, delicious!
Hosting a brunch next weekend and was looking for an easy egg veggie and meat dish. This is perfect!
Helen says
Thanks so much for the feedback, Dave! I love that you spiced it up! Hope the brunch went OK! 🙂
