What French dish is a savory custard tart from the Lorraine region?

The French dish that is a savory custard tart from the Lorraine region is Quiche Lorraine.

Its filling traditionally combines eggs, cream, and bacon or ham in an open pastry case. The eggs and cream set into the dish’s characteristic savory custard as it bakes. It may be served hot, warm, or cold.

Quiche Lorraine is a regional version of quiche, a broader French tart category that can include cheese, vegetables, seafood, or other meats. Early versions used a bread-dough crust, while modern recipes usually use shortcrust or puff pastry. The dish dates back at least to the 16th century, although it became widely known outside Lorraine only during the 20th century.

A common mix-up concerns cheese: many modern recipes include Gruyère or another cheese, but traditionalists often regard cheese as an addition rather than an essential ingredient. The name quiche may be related to the German word Kuchen, meaning cake or tart.
