Quiche, a savory French pie, is prepared by filling a pastry crust with meat, cheese, vegetables, or seafood, and a custard made with eggs and cream or milk. Shortcrust pastry is typically used, but puff pastry can work as well. There are several versions of the dish, including the traditional quiche Lorraine, quiche Florentine, quiche au fromage, and quiche aux champignons.
