Make-ahead and reheat, this crustless quiche is perfect to whip up in minutes when you need one, and they’re wonderful to serve all year round. 

Our Italian mothers and grandmothers always made simple meals like this quiche, only they called them frittata or omelet.  

And it was always 100% crustless.

It’s SO delicious! 

I made it the other day and it was gone in minutes.  Everyone was having seconds and even thirds, it turned out so good, everyone raved about it all day.  The next morning, my husband even enjoy it cold, for breakfast.


So, what is Quiche?   

The “quiche” is from French cuisine and it became popular when Julia Child first broadcasted the recipe on television.  It’s made in a pastry crust filled with eggs, cream, and sometimes with meat or other veggies, and it’s baked in the oven.  The quiche Lorraine is the most popular one made with bacon and it can be served either warm or cold.
