'cheese soufflé') is a Dutch snack of melted cheese inside a thin dough-based wrap which has been breaded and then deep-fried.
[1] It is either bought ready-made frozen and deep-fried at home, or ordered at snackbars in the Netherlands, where it is one of the few vegetarian fast-food snacks available.
[2] At certain Dutch fastfood outlets, such as FEBO or Smullers, it is possible to purchase a kaassoufflé without having to order it at the counter; instead it can be had directly from an automatiek, a coin-operated vending machine.
Smaller versions, called mini-kaassoufflés, are usually sold for consumption at home, or for at the aforementioned borrel where they are usually eaten as part of a bittergarnituur, a selection of snacks to go with drinks.
This is simply done by wrapping a slice of cheese, with or without additional spices, inside puff pastry and then baking it in an oven.
