Yes. Here are detailed instructions for preparing in advance: Freezing before baking: Assemble the quiche as instructed (par bake the crust) and place in the freezer until solid. Then, remove the quiche, wrap tightly in plastic and then foil. You may keep frozen for up to a month. To bake, remove the wrap and bake straight from the freezer, note that the bake time may increase by as much as 10-15 minutes. Freezing after baking: Bake the quiche as instructed and cool completely. Wrap in plastic and then foil and freeze for up to a month. To reheat, thaw the quiche overnight in the refrigerator then pop in a 325F (165C) oven and heat until warmed through (about 15 minutes). Refrigerating: You can bake the quiche and cover and refrigerate for up to 3 days before serving. Reheat in a 325F (165C) oven for 15-20 minutes.
