In Finnish cuisine, rosolli is a salad eaten mostly as a cold side dish, in particular as part of the traditional Finnish Christmas meal.

Rosolli is made of cooked, diced root vegetables, especially beetroot, carrot and potato, often combined with one or more of pickled cucumber (of either the vinegar or brine type), raw onion and apple.

Variations may also include additional ingredients such as pickled herring or boiled egg, in which case the salad is more likely served as a starter (appetizer) rather than a side dish to a main course.

Similar dishes are found throughout northern Europe, from the Low Countries across Scandinavia to Russia.

[1] In western Finland, alternative terms such as punainen salaatti (literally "red salad", rendered dialectically) or sinsalla (probably from the Swedish word sillsallad, for "herring salad") are traditionally used.
