Zupa Grzybowa – Dried Polish Mushroom Soup

To complement our recent highlight of Cycling Krakow to Slovakia Plus! Budapest, we went in search of a traditional Polish recipe. After consulting Kathie Dudzinski – she and Paul, who was born in Poland, live in Fort Collins and are dear friends of Sales and Marketing Manager Carol Busch, we landed on a mushroom soup recipe that calls for “Polish dried mushrooms.” Kathie got the recipe from Paul’s mom. As with most recipes, this is a family version that likely differs from others you’ll see online. A search for “zupa grzybowa” will turn up many iterations!

Kathie usually makes the soup for a crowd and doubles or triples the recipe. She says this soup is best made 2-3 days ahead, heated and cooled a few times, although confessses that they usually eat a bit right away! The recipe that follows is a ballpark guide. Let your nose and tastebuds be your guide.
