Galette is a term used in French cuisine to designate various types of flat round or freeform crusty cakes, or, in the case of a Breton galette (galette bretonne), a pancake made with buckwheat flour usually with a savoury filling. Of the cake type of galette, one notable variety is the galette des Rois (King cake) eaten on the day of Epiphany. In French Canada, the term galette is usually applied to pastries best described as large cookies.
Galettes campinoises are a type of galette or waffle popular in Belgium
Galette, or more properly Breton galette (French: Galette bretonne, Breton: Krampouezhenn gwinizh du), is also the name given in most French crêperies to savoury buckwheat flour pancakes, while those made from wheat flour, much smaller in size and mostly served with a sweet filling, are branded crêpes. Galette is a type of large, thin pancake mostly associated with the region of Brittany, where it replaced at times bread as basic food, but it is eaten countrywide. Buckwheat was introduced as a crop suitable to impoverished soils and buckwheat pancakes were known in other regions where this crop was cultivated, such as Limousin or Auvergne.
It is frequently garnished with egg, meat, fish, cheese, cut vegetables, apple slices, berries, or similar ingredients. One of the most popular varieties is a galette covered with grated Emmental cheese, a slice of ham, and an egg cooked on the galette. In France, this is known as a galette complète (a complete galette). Another variety is a hot sausage wrapped in a galette (called galette saucisse, a tradition of Rennes, France) and eaten like a hot dog.

The filling for a paper-thin Breton galette is always simple. The most popular, called a complet, includes ham and egg and often a spoonful of fresh cheese. You can ask for the egg to be brouillé, briskly scrambled on the hot galette, or miroir, left untouched to bake on top. When the galette is pleated, the golden egg yolk peeps out of the crisp brown folds.
