Zupa Grzybowa: Polish Dried Mushroom Soup
Dried porcini bring a deep, woodsy aroma to the broth, while carrot, parsley root and celeriac add gentle sweetness. The soup is lightly thickened rather than heavy, and sour cream rounds the mushroom flavour with a mild tang. Noodles make it a satisfying bowl without obscuring the mushrooms.
Mushroom soup appears in Polish culinary references and has different roles at different tables. Tourism sources describe both fresh-porcini soup and dried-mushroom preparations; one regional account records mushroom soup becoming established among central Polish Christmas Eve dishes after the Second World War. Families and regions choose different soups and accompaniments, so this recipe is an everyday version that can also suit a festive meal.
For a clean, fragrant broth, filter the porcini soaking liquid through a fine sieve lined with a coffee filter, then simmer the mushrooms until fully tender. Add the butter-flour roux gradually so it blends without lumps. Whisk hot soup into the sour cream, take the pot off the heat, and stir the mixture back in gently.
