Serves 6
Heat oil in a large pot and cook the onion until soft, about 8 minutes.
Stir in flour and cook for 1 minute.
Add sauerkraut with some of its brine, potatoes, water or stock, caraway seeds and bay leaves. Bring to a simmer.
Cook for 25 minutes until the potatoes are tender and the flavors meld.
Stir in the sliced sausage and simmer for another 10 minutes until heated through.
Season with salt, remove bay leaves, and serve hot with a dollop of sour cream.
Use some of the sauerkraut's own brine in the soup for extra tang and depth, rather than discarding it entirely.
Balance the sourness to taste — rinse the sauerkraut briefly first if it's especially sharp.
This soup reheats and often improves in flavor the next day.
Add smoked ham hock instead of sliced sausage for a richer, more traditional version.
Some households add a bit of caraway seed-infused flour for extra depth.
Serve with dark rye bread on the side.
Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop or in the microwave with a splash of water or stock to loosen the texture.

Yes, it reheats very well and the flavor often deepens after a day resting in the fridge.
A firm smoked sausage like kielbasa or a Czech smoked pork sausage gives the best flavor and texture.
Rinse the sauerkraut briefly before adding, or use less of its brine, then adjust with a pinch of sugar if needed.
