Bouneschlupp is a classic Luxembourgish soup made with green beans, potatoes, smoked bacon, and onions. Regional variations of this dish may include additional ingredients such as carrots, leeks, or celery. Metworst or other types of heavily spiced sausages may be added as well.
Although bouneschlupp is considered a national dish of Luxembourg, it can also be found in the German state of Saarland, Lorraine (France), and the historical regions of Gaume and Arelerland in Belgium. It is traditionally served hot with potato pancakes called
gromperekichelchen and (optionally) a dollop of sour cream on the side.
