Polish White Borscht Soup Recipe
Now that you’re intrigued, it’s time to bring this flavorful soup to life in your kitchen. The following recipe is for a traditional Polish White Borscht Soup. Prepare yourself for a cozy, comforting dish that will warm you from the inside out.
Ingredients Needed
For The Soup
- 4 cups vegetable or chicken broth (this acts as the flavorful liquid base)
- 1 ½ cups fermented rye flour (żur) (this is the heart of the soup’s flavor)
- 2 medium potatoes (peeled and diced – they help add some body to the soup)
- 1 medium onion (finely chopped – adds sweetness and depth)
- 2 cloves garlic (minced – for that punch of flavor)
- 1 tablespoon vegetable oil (for sautéing the onion and garlic)
- 1 teaspoon dried marjoram (a key herb that brings a slightly floral note)
- 2 bay leaves (adds a subtle depth of flavor)
- 1 tablespoon white vinegar (to enhance the tanginess)
- 1 teaspoon salt (or to taste)
- 1 teaspoon black pepper (freshly ground for an added depth of flavor)
- 2-3 boiled eggs (cut into halves or quarters – adds richness and creaminess)
- Smoked sausage (kielbasa) or any other smoked sausage (sliced into rounds or chunks – this gives the soup its meaty, smoky element)
For The Fermented Rye Flour (Żur) Starter
- ½ cup rye flour
- 1 ½ cups warm water
- 2-3 tablespoons of vinegar or lemon juice
(If you don’t have access to pre-made żur, making your own starter with rye flour and vinegar is a great alternative. You’ll need to ferment it for about 3-4 days, so plan ahead.)
Cooking Instructions
-
Make The Żur Starter (if Needed)
- Combine the rye flour and warm water in a jar. Stir until the mixture forms a smooth paste.
- Add a tablespoon or two of vinegar or lemon juice and cover loosely with a lid. Let it sit at room temperature for 3-4 days, stirring once a day, until it starts to ferment and develop a sour aroma.
-
Prepare The Soup Base
- Heat the vegetable oil in a large pot over medium heat. Add the chopped onion and garlic, and sauté them until they become soft and translucent, about 4-5 minutes.
- Add the diced potatoes, bay leaves, and marjoram. Stir for a minute to combine.
-
Bring The Broth Together
- Pour the vegetable or chicken broth into the pot. Stir everything to combine and bring the mixture to a simmer. Let it cook for about 10 minutes, or until the potatoes are nearly tender.
-
Incorporate The Żur
- Add the fermented rye flour (żur) starter into the pot, stirring to blend it with the broth. Continue simmering for 15-20 minutes, allowing the soup to thicken slightly and absorb the flavors.
-
Season The Soup
- Taste and adjust the seasoning. Add white vinegar for more tang, salt, and pepper to taste.
-
Add The Sausage And Eggs
- Slice your smoked sausage into rounds or chunks and add them to the pot. Let them simmer in the soup for another 5-10 minutes to release their smoky flavor.
- Gently add the boiled eggs and heat through, but don’t let them break apart.
-
Serve
- Ladle the soup into bowls, making sure each serving gets a portion of sausage and a piece of egg.
- Garnish with fresh herbs like parsley if you prefer, and enjoy the rustic flavors of this classic Polish dish.
Ingredient Insights
- Fermented Rye Flour (Żur): The star of the dish, fermented rye flour is what gives Żurek its signature tang. The fermentation process makes the rye slightly sour, giving the soup that zesty flavor profile. You can find it in Polish or Eastern European grocery stores, or you can make your own from scratch by mixing rye flour with water and vinegar and letting it sit until it ferments.
- Smoked Sausage (Kielbasa): Kielbasa, or Polish sausage, is often smoked, which imparts a rich, savory flavor to the soup. It’s not just a protein but also an essential part of the soup’s flavor profile. The smokiness infuses the broth and adds a lovely depth.
- Marjoram: This herb is a classic addition to many Polish dishes. It’s slightly sweet, earthy, and floral, providing an aromatic lift to the soup without overpowering the tangy flavor of the rye.
- Eggs: Hard-boiled eggs in Żurek aren’t just for decoration; they add creaminess and richness to the soup. They balance the sourness of the broth and contribute to the hearty, comforting nature of the dish.
Expert Tips
- Let the Soup Sit: If you have time, let the soup sit for a few hours or even overnight. Like many stews and soups, Żurek tends to taste even better the next day as the flavors meld together.
- Use Quality Smoked Sausage: If possible, use high-quality smoked sausage or kielbasa. The flavor of the sausage really comes through, so don’t skimp on it. A rich, smoky kielbasa will make all the difference.
- Adjust the Sourness: The tangy quality of Żurek is key, but the level of sourness can be adjusted. If you like a more pronounced sour taste, use more fermented rye flour or add extra vinegar. If you prefer a milder taste, reduce the amount of vinegar and żur starter.
- Vegetarian Version: For a vegetarian option, swap the sausage for a plant-based sausage or other smoky-flavored substitutes. You can also add more vegetables like carrots, leeks, or mushrooms for added texture and flavor.
Recipe Variations
- With Mushrooms: Adding earthy mushrooms, especially wild ones like chanterelles or porcini, will give the soup an additional layer of umami and depth. Just sauté the mushrooms with the onion and garlic for an extra punch of flavor.
- Vegan Żurek: Omit the sausage and eggs, and substitute vegetable broth for the meat-based broth. You can use a vegan smoked sausage to keep the smoky flavor intact.
- Extra Creamy: If you want an ultra-creamy version, stir in a few tablespoons of sour cream or heavy cream at the end of cooking. This will smooth out the tanginess and give the soup a more indulgent texture.
