Potato Soup with Dumplings

This is the kind of soup that shows up in Czech, Polish, and German kitchens when the weather turns. A sturdy base of new potatoes, butter-softened onions, and celery, then tender little egg-and-flour dumplings (the same ones you’d find in a German Leberknödel or a Czech knedlík) dropped by teaspoonfuls into the simmering pot.

The dumplings are small but critical. Beating butter with flour first, then whisking in eggs, gives you a thick paste that holds its shape when it hits hot broth. A pinch of freshly grated nutmeg in the dumpling batter plays against the earthy potatoes in a way that’s a signature of Central European soup cookery.

New potatoes are the right pick. Their waxy flesh holds its shape during the simmer instead of breaking down into mashed. Old starchy potatoes would turn the broth cloudy and thick.

Kitchen Tips

• Drop the dumplings one at a time from a teaspoon dipped briefly in hot broth each time. Wet spoons release the batter cleanly. Dry spoons stick.
• Don’t let the soup boil hard once the dumplings go in. A gentle simmer keeps them intact. Vigorous boiling shreds them.
• Finish with a generous swirl of cold sour cream in the bowl rather than stirring it into the pot. Added to the hot pot, it can break and curdle.
• Scatter fresh parsley just before serving. It freshens the heavy broth and adds a bright green contrast against the pale soup.

Variations

• Swap water for good chicken or vegetable stock for a richer, more savory broth.
• Stir a teaspoon of dill into the dumpling batter for a Hungarian-style profile.
• Add a handful of crumbled crispy bacon on top with the parsley for smoky richness.
