A flan is a type of open tart commonly found in British baking and patisserie. In this sense it describes a shallow case of pastry or sponge holding a sweet or savoury filling. The term can cover a wide range of preparations, from fruit and jam-topped tarts to egg-and-cream custard fillings, and it often appears in bakeries, teatime menus and home baking.

Characteristics and construction

Most traditional flans are round and use a shortcrust pastry base, though some recipes use a sponge case as an alternative for lighter texture. The case is filled before or after baking depending on the filling: heavier custards are typically poured into a pre-baked shell, while fruit or jam may be added to a baked sponge. The result is an exposed filling rather than a fully enclosed pie.

History and name

The word flan has medieval roots in several European languages and originally referred to a flat cake or tart. Over centuries the form evolved in domestic and professional kitchens, producing both savoury and sweet variants. Flans in Britain have long been part of afternoon tea and dessert traditions, adapting regional ingredients and preferences.

Uses, common fillings and examples

  • Sweet: custard tarts, fruit flans topped with berries or sliced fruit, jam tarts and baked cream fillings.
  • Savoury: vegetable or meat fillings bound with egg or cream; these overlap with quiches but tend to be shallower and more tart-like.
  • Regional counterparts: French flan (flan pâtissier) is a dense custard tart, while Spanish and Latin American flan usually means a caramel-topped baked custard (crème caramel).

Distinctions and notable facts

In British usage a flan emphasizes the open case—see examples of open pastry and the alternative of a sponge case. For context within cuisines, note that listings of British cuisine often treat flans as distinct from pies and enclosed pastries. Understanding the term requires attention to regional meanings: the same word can denote quite different desserts in other languages.

Flans remain a flexible template in baking: simple to assemble, adaptable to seasonal produce, and served warm or cold depending on the filling. Their variety illustrates how a basic format — a shallow case supporting a flavoured filling — can produce many familiar dishes across European and global cooking traditions.
