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 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.

Questions and Answers…

1.  Can We Make Quiche Ahead?

Yes, indeed.  You can make this crustless quiche ahead of time. It’s best to bake it, then reheat it when you’re ready to serve it. 

2.  Can We Freeze Quiche? 

Yes, you can freeze quiche as long as you bake it first.  Allow it to cool completely before freezing. Cover with aluminum foil and freeze.  Best to freeze for up to one month only, after that it will develop freezer burns.

3.  How To Reheat?

Remove frozen quiche from the freezer and allow it to sit on your counter for at least one hour before reheating it.  Reheat in your preheated oven at 350 degrees F (180C), and reheat for 10 minutes.
