As Easter approaches, many Polish kitchens start thinking about Żurek — the beloved sour rye soup that appears on holiday tables across Poland. The heart of this soup is zakwas, a naturally fermented sour starter that gives żurek its unmistakable tangy flavor.
But żurek flavors aren’t just for soup. Today I’m sharing a simple and deeply comforting dish: Kopytka with a Creamy Żurek Sauce. It’s earthy, slightly sour, fragrant with dill, and perfect for cool spring days when you’re already thinking about Easter cooking.
The dumplings themselves are the classic Polish Kopytka — soft potato dumplings that are simple, humble, and incredibly versatile. If you need the recipe, you can find it here: Kopytka recipe.
Once the dumplings are ready, the sauce comes together quickly and fills the whole kitchen with that unmistakable Polish aroma of butter, mushrooms, and sour rye.

Ingredients
- prepared kopytka (recipe above)
- 1 small onion, finely chopped
- 2 tablespoons butter
- 1–2 cups wild mushrooms (fresh or frozen)
- a splash of water or vegetable broth
- 1 cup żurek starter (zakwas)
- salt and black pepper to taste
- a splash of sweet cream (optional)
- a generous handful of fresh dill, chopped
Here is a short video on how I make Kopytka with Creamy Żurek Sauce:
Instructions
1. Sauté the Onion
In a pan, melt the butter over medium heat. Add the chopped onion and sauté until soft and fragrant.
2. Add the Mushrooms
Add the wild mushrooms — fresh or frozen both work beautifully. Cook for a few minutes until they release their aroma.
Pour in a small splash of water or vegetable broth so the mushrooms can soften and cook through. Simmer for about 5 minutes.
3. Add the Żurek Starter
Pour in one cup of zakwas (żurek starter) and let the sauce simmer gently. As it cooks, it will thicken slightly and the flavor will deepen. Let it reduce a bit so the sauce becomes rich and concentrated.
Season with salt and black pepper.
If the zakwas is very tangy, you can soften the flavor with a small splash of sweet cream.
4. Finish with Dill
Just before serving, add a generous handful of fresh dill. This bright herbal note brings everything together beautifully.
How to Serve
Serve the hot sauce over:
Both dumplings absorb the sauce perfectly.
A Little Easter Kitchen Tip
With Easter approaching, this is also a great moment to start thinking about making your own zakwas for żurek.
You can even prepare a gluten-free version, using gluten-free grains if that’s the standard in your kitchen. Polish traditions are wonderfully flexible — you don’t have to give them up, sometimes you just adjust them a little. Because in the end, what matters most is keeping the flavors and memories alive. And a bowl of soft dumplings covered in a tangy mushroom żurek sauce does exactly that.
