Pro Tips
I want to say a bit about the baking. It’s going to depend on the size of your quiche. I made a VERY deep one and it took about an hour in the oven. I will say that as it cools the filling sets up more so don’t be afraid of a bit of wobble. You can also tent your crust for part of the baking to prevent burning but it’s kinda optional depending on the bake time you’ll need.
