Janssons frestelse (Swedish pronunciation: [ˈjɑːnˈsɔns ˈfrɛstɛlsə], Jansson's temptation) is a traditional Swedish casserole made of potatoes, onions, pickled sprats, bread crumbs and cream. It is commonly included in a Swedish Christmas smörgåsbord, but can be eaten on other occasions such as Easter. The dish is also common in Finland as Janssonin kiusaus.
