Though it employs simple ingredients, prežganka is a Slovenian classic. This nourishing soup is prepared with water, flour that is lightly browned in oil, and spices such as caraway seeds, paprika, salt, and pepper. A lightly whisked egg is often added into the soup, which gives the dish a thicker consistency and a more complex flavor.

Prežganka is commonly served with croutons or toasted bread on the side and is believed to be a great hangover remedy. A similar dish is found in Croatia, where it goes under the name prežgana juha or ajnpren juha, and in Germany, where it is commonly referred to as einbrennsuppe.
