  3. Beat the eggs and cream together in a bowl, then add the cheese and some seasoning. Stir in the onions, then spoon the mixture into the flan case. Bake for 25-30 mins until lightly set and browned.

Vegetarian Parmesan cheese? What is a non vegetarian cheese?

Usually Parmesan cheese isn't vegetarian due to the rennet that is extracted from a calf's stomach. Vegetarian Parmesan is made with microbial rennet. You can use either of those if you don't care.

I found I could cut down all the timings and the result was delicious (even without the cheese which I left out because it needed to be dairy free and hence I swapped the cream for a dairy free version).

This tart is divine, I substituted the cream for half milk, half (lightest) cream cheese.
Will definitely be making this again, it was so easy to make too!

This was great and so simple! I didn't have any double cream so but I had mascapone and cream cheese which I loosened with a little milk, I also used a little nutmeg, perfect for lunchboxes! I love the comment below about putting some blue cheese with this, which I will try next time.

Made it today for lunch and it went down a treat! I added extra oregano and nutmeg plus extra Parmesan. Will be making this again.

Made a double batch, but using shop bought pastry. I really liked this dish, husband thought it was a bit sweet, but nothing left on guests plates. So guess it was a hit. I will be making it again, may even try a little blue cheese.

Gorgeous! Creamy and tender and so beautiful with a golden brown top! Was lovely the next day too and I'll remember to make it for a picnic when summer comes around again! My veggie friends loved it when I made individual versions for them as a dinner party main course - gratifyingly easy!

Made this with one red and one white onion, no cream, just semi-skimmed milk, 3 eggs to 1/2 pint milk, made my own potato pastry for a tasty gluten free vegitarian quiche - lovely.

Thank you, perfect suggestion.

Absolutely adorable!!! It was devoured in a few minutes at a party.... I did add more salt and decided to put some nutmeg in it, which I think it always compliments white creamy sauces and dishes...

Made this the other day and it turned out really good. Sadly we ended up eating it almost all between the two of us with barely a slice left for the next day, so feel fat a guilty! lol

Only added half the cream and checked the seasoning before cooking and for me the balance of the sweet onions and the salty cheese was fine. Used my own pastry and all was good, enough left for another.

Now in the process of making a purple asparagus and stilton tart, but think I should have used another egg as there is not as much volume as with the onions. Oh well.

As many comments suggest a delicious creamy quiche. Super with a tossed green salad for a lunch with friends. Used all the cream recommended and a deep tin. No problems setting. I keep a few chickens and they lay large to extra large eggs. Also found it easy and quick to do. Next time and I'm sure there will be one, think I will add some fresh thyme to balance the sweetness of the onions.

Was very surprised at how delicious this was; better than a supermarket one I'd recently bought, about twice the size and half the cost to make. Definitely recommended.

I made this for my son's second birthday party and it disappeared in seconds.

I made the case from the cheesy pastry from the slow roasted pesto tart and after reading reviews made sure that I seasoned everything well.

Fantastic

really delicious tart. Next time I think I'll use half parmesan and half cheddar or gruyere for a change
