Absolutely! You can make your pie crust 2-3 days prior and tightly wrapping the dough and refrigerating it until ready to use. Just remove it from fridge and roll it out into the size/shape for your quiche dish. Then whip together the quiche filling ingredients. Also, you can bake your quiche ahead of time, let it cool completely, and then store it in the refrigerator for up to 4 days.
