Soups & Stews
This Polish soup recipe delivers the velvety richness of traditional Żurek, where tangy fermented rye flour meets creamy sour cream and fresh dill. The broth develops deep, savory layers as it simmers, while the sour cream adds a signature silky texture that balances the dish's bold flavors.
My version stays true to Polish roots while making it accessible for home cooks with simple techniques and pantry-friendly ingredients.
The secret to authentic Żurek lies in the fermented rye flour starter, which creates that signature tangy base. Don't worry if you can't find it—store-bought sauerkraut juice works beautifully as a substitute.
The soup comes together in just one hour, with most of that time spent simmering to develop the broth's depth. Fresh dill and a dollop of sour cream at the end elevate it from hearty to restaurant-quality.
What you'll end up with is a creamy, aromatic soup with a vibrant green hue from the dill and a smooth, almost custard-like consistency from the sour cream. Each spoonful delivers layers of flavor—earthy from the rye, tangy from the fermented base, and fresh from the herbs.
This is comfort food at its finest, perfect for chilly evenings or family gatherings where tradition meets homestyle cooking.
Serve it with crusty rye bread to soak up every last drop of that velvety broth. The recipe scales easily for crowds, and leftovers actually taste better the next day as the flavors meld further. Let's get cooking—this soup will become your new go-to for Polish-inspired dinners.
Ingredients for polish soup
Pantry staples plus a few Polish market finds—nothing fancy, just bold flavors.
| Ingredient | Amount | Notes |
|---|---|---|
| Fermented Rye Flour 🌾 | ½ cup | Or sauerkraut juice substitute |
| Chicken Broth 💧 | 6 cups | Low-sodium preferred |
| Potatoes 🥔 | 1 ½ lb | Yukon gold preferred, cubed |
| Carrots 🥕 | ½ lb | Baby carrots work fine |
| Onion 🧅 | 1 whole | Yellow or white, chopped |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth |
| Sour Cream 🥛 | ½ cup | Full-fat for creaminess |
| Eggs 🥚 | 2 whole | Room temperature preferred |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Crusty Rye Bread 🍞 | 8 slices | For serving, optional |

Fermented rye flour is the soul of Żurek. Polish markets or specialty stores carry it, but sauerkraut juice works in a pinch—just use half the amount. For the potatoes, Yukon gold gives that creamy texture, but Russets work too if that's what you've got. The carrots can be baby carrots if you're lazy—no judgment. Fresh dill is ideal, but dried works at one-third the amount. I always grab extra dill because it wilts fast, and half goes in the soup while the other half gets chopped for garnish.
No fermented rye flour? Sauerkraut juice or even a splash of vinegar gets you close—just taste as you go. The broth can be store-bought (low-sodium) or homemade—your call. Eggs are key for that velvety finish, but if you're vegan, silken tofu blended in works surprisingly well. The rye bread? Any crusty bread does the trick—Trader Joe's has great options if you're not near a Polish deli. The butter adds richness, but if you're watching calories, olive oil works too—just don't skip it entirely.
This soup tastes even better the next day—honestly, the flavors meld into something magical. Keeps for 4-5 days in the fridge, freezes for 3 months. I always make a double batch because it disappears fast. Store the broth separately if you're freezing, then reheat and stir in the sour cream and eggs when you're ready to serve. Garnish with fresh dill and parsley right before eating—that's non-negotiable for the full experience.

Step-by-step instructions for Polish sour cream and dill soup
Here's how to make this creamy, comforting Polish soup that's rich with sour cream and fresh dill.
Sauté the Aromatics and Prepare the Roux
Melt the 2 tablespoons butter in a large pot over medium heat. Add the chopped 1 whole onion and cook for 5 minutes until soft and translucent. Stir in the 4 cloves minced garlic and cook for another 30 seconds until fragrant.
Reduce heat to medium-low and slowly whisk in the 0.5 cup fermented rye flour, creating a thick paste. Cook for 2-3 minutes until the mixture turns golden brown and nutty. This roux forms the creamy base of your soup, so don't rush this step—it's what gives the soup its velvety texture.
Build the Vegetable Base
Gradually pour in the 6 cups chicken broth, whisking constantly to prevent lumps. Bring to a gentle simmer and add the cubed 1.5 lb potatoes and sliced 0.5 lb carrots. Stir in the 2 whole bay leaves and 1.5 teaspoons salt. Let the soup simmer for 10 minutes until the vegetables begin to soften.
Here's where the magic happens: the fermented rye flour releases its tangy depth, while the potatoes and carrots absorb the broth's flavor. You'll know it's ready when you can pierce the potatoes with a fork—they should be tender but not falling apart.
Finish with Creamy Richness
Remove the 2 whole bay leaves and stir in the 0.5 cup sour cream, mixing gently to blend it smoothly into the soup. The heat will warm the sour cream but won't curdle it—just enough to create that signature Polish creaminess. Add the 0.5 teaspoon black pepper and taste, adjusting the salt if needed.
In a separate bowl, whisk the 2 whole eggs lightly. Slowly ladle about 1 cup of hot soup into the eggs while whisking constantly to temper them. Then pour the egg mixture back into the pot, stirring continuously for 1-2 minutes until the soup thickens slightly. This step ensures the eggs cook gently without scrambling.
Garnish and Serve Warm
Remove the pot from heat and stir in the 0.25 cup chopped fresh dill. The bright, herby flavor cuts through the richness perfectly. Ladle the soup into bowls and garnish each serving with a sprinkle of 0.03 oz chopped parsley and a few crusty rye bread slices on the side.
This soup tastes best served immediately while still warm. The contrast of the crispy rye bread against the creamy soup makes every bite satisfying. If you prefer, you can also serve it with a dollop of extra sour cream on top for added richness.
Pro Tips For Making Polish Soup
- Bloom the Flour First: Dump that fermented rye flour straight into boiling broth and you’re asking for a gluey mess. Instead, whisk it with cold water (about 1:3 ratio) until smooth, then slowly ladle it into simmering broth while stirring constantly—this prevents clumping and gives you that silky texture. I learned this the hard way after scraping a pot full of gummy lumps off my walls.
- Sweat the Onion Low: Polish soup isn’t about caramelized onions—it’s about flavor extraction. Cook your chopped onion in a dry pot over medium-low heat until it’s translucent but not brown (about 8–10 minutes). Too much heat and it burns; too little and you’ll be waiting forever. Sounds boring, but this is the thing that matters most for depth.
- Cut Potatoes Evenly: Uneven potato chunks mean some will turn to mush while others stay rock-hard. Use a knife to slice them into 1.5-inch cubes—big enough to hold shape but small enough to cook through. Pro tip: Soak them in cold water for 10 minutes first to rinse off excess starch, which keeps them from turning gluey in the broth.
- Simmer, Don’t Boil: Once everything’s in the pot, keep the heat at a gentle simmer—tiny bubbles at the edges, not a rolling boil. Boiling breaks down the rye flour’s structure and makes the soup cloudy. Let it cook covered for 20–25 minutes, stirring occasionally, until the potatoes are tender but not falling apart. Patience here makes all the difference.
Creative variations of these flavors
Classic Żurek Twist
For a more traditional approach, swap the sour cream for quark cheese—a Polish staple that adds a lighter, tangier flavor. Use ½ cup quark instead of sour cream, and stir it in at the end with the dill.
Quark is available at Polish markets or specialty stores, and it creates a smoother, less rich finish that still delivers that signature tang. 🌾
Smoky Beef Version
Transform this into a hearty beef stew by adding 1 lb stew beef (chuck or round) along with the potatoes and carrots. Brown the beef in the pot before adding the broth, and simmer for an extra 20 minutes until tender.
Finish with a sprinkle of smoked paprika for depth—this version is perfect for cold winter nights and pairs beautifully with dark rye bread.
Vegetarian Adaptation
Skip the eggs and use ½ cup silken tofu blended with 1 tbsp lemon juice instead for a creamy, dairy-free option. Boost umami with 1 tbsp soy sauce added to the broth, and include ½ cup mushrooms (cremini or shiitake) with the carrots.
The fermented rye flour still provides that signature tang, making this version just as satisfying for plant-based eaters.
Spicy Polish Kick
Add a Polish-style hot sauce like Chili Olek (find it at Polish markets) or Tabasco for heat lovers. Stir in 1-2 teaspoons to taste after adding the sour cream. For extra spice, include ½ tsp cayenne pepper with the black pepper.
The heat cuts through the richness beautifully, making this a great option for those who love bold flavors.
Creamy Mushroom Fusion
Incorporate 1 lb wild mushrooms (cremini, shiitake, or oyster) sliced and sautéed with the onions. Add them to the pot with the potatoes and carrots. For extra creaminess, stir in ¼ cup crème fraîche along with the sour cream.
The earthy mushrooms pair perfectly with the dill and rye flour, creating a rich, umami-packed variation that feels luxurious yet homestyle.
Lighter Summer Version
Use ½ cup low-fat Greek yogurt instead of sour cream to cut calories while keeping the tang. Add ½ cup zucchini (diced) with the carrots and reduce the potatoes to 1 lb.
Finish with extra fresh dill and a squeeze of lemon juice for brightness. This version is perfect for warm weather when you want something lighter but still packed with flavor. 🌿

Frequently asked questions
What makes this Polish soup different from other creamy soups?
The signature tang comes from fermented rye flour (or sauerkraut juice), while the eggs and sour cream create that signature velvety texture. Unlike French onion or potato leek, this soup balances rich creaminess with bright dill and a subtle sourness that's uniquely Polish.
Can I substitute fermented rye flour if I can't find it?
Use ½ cup sauerkraut juice or a mix of ¼ cup vinegar + ¼ cup water for tang. For deeper flavor, add 1 tsp lemon juice too. The key is achieving that signature sour note—just taste as you go and adjust.
Why does the recipe call for room-temperature eggs?
Room-temperature eggs blend more smoothly into the hot broth, preventing curdling. Cold eggs can create lumps when added to hot liquid. Simply take them out of the fridge 15-20 minutes before using for perfect results.
How do I prevent the soup from getting too thin when reheating?
Always reheat gently on low heat, stirring constantly. If it's too thin, mix 1 tbsp cornstarch with 2 tbsp cold water, stir into the soup, and simmer 1-2 minutes until thickened. Never boil after adding sour cream or eggs.
What's the best way to store leftovers?
Store in an airtight container in the fridge for 4-5 days. For freezing, keep broth and solids separate—reheat broth first, then stir in sour cream and eggs when serving. The flavors actually deepen overnight!
