*This is a great dish to prepare ahead of time too. You can assemble everything a day or two in advance, place on a cookie sheet with sides, cover and store in the fridge. To bake, remove from the fridge and let the quiche sit at room temperature while the oven preheats. Then bake when ready. You can also pre-bake the quiche and then just warm it up before serving. I personally like to prep my quiche in advance though. Then I just bake before serving. I think the flavors are freshest this way!
