Rösti or rööschti is a Swiss dish consisting mainly of potatoes, sautéed or shallow-fried in a pan. It was originally a breakfast dish, commonly eaten by farmers in the canton of Bern, but is now eaten all over Switzerland and around the world. The French name röstis bernois directly refers to the dish's origins.

Swiss cuisine is an ensemble of national, regional and local dishes, consisting of the ingredients, recipes and cooking techniques developed in Switzerland or assimilated from other cultures, particularly neighboring countries. The diversity and comprehensiveness of Swiss gastronomy reflects the linguistic, cultural and geographical diversity. The climate of Switzerland allows for a large variety of terroirs, and therefore a wide range of indigenous food, from simple cereals to refined products like cheese and wine.
