Polish Soup in Bread: How to Make Żurek Bread Bowls

Polish soup in bread is a serving of żurek, a tangy Polish soup made with fermented rye starter, sausage, and potatoes, ladled into a hollowed-out bread loaf. The crisp, sturdy bread makes an edible bowl and balances the soup’s sour, savory flavor; families and regions vary the soup, and it is also commonly served in an ordinary bowl.

Ingredients

4 sturdy round rye or sourdough bread rolls, 8–10 oz each (225–280 g each)
1 tablespoon neutral oil (15 ml)
4 oz bacon, diced (115 g)
1 medium yellow onion, finely chopped, about 1 cup (150 g)
2 garlic cloves, minced, about 2 teaspoons (6 g)
4 uncooked Polish white sausages, about 12 oz total (340 g); use fresh, unsmoked biała kiełbasa if available
6 cups chicken stock or broth (1.4 L)
2 medium potatoes, peeled and cut into ½-inch cubes, about 2 cups (350 g)
2 cups bottled or fresh żurek zakwas, fermented rye soup starter (480 ml)
2 bay leaves (about 0.2 g)
1 teaspoon dried marjoram (1 g), lightly crushed between your fingers
1 teaspoon fine salt (6 g), plus more to taste
½ teaspoon freshly ground black pepper (1 g)
4 large eggs (about 200 g without shells)
½ cup sour cream (120 g), for serving
2 tablespoons chopped fresh dill (6 g), for serving
1 tablespoon prepared horseradish (15 g), optional

Instructions

Prepare the bread and vegetables (25 minutes). Cut a circle around the top of each roll and lift off the lid. Pull out the soft interior, leaving a shell about ¾ inch (2 cm) thick so it can hold hot soup. Keep the lids for dipping. Chop the onion, garlic, bacon, and potatoes, and set the rolls aside. If the bread feels soft or has a thin crust, save it for serving alongside rather than using it as a bowl.
Brown the bacon and soften the aromatics (12 minutes). Heat the oil in a large heavy pot over medium heat. Add the diced bacon and cook for about 7 minutes, stirring occasionally, until browned and some fat has rendered. Add the onion and cook for 5 minutes, stirring, until softened but not deeply browned. Stir in the garlic for about 30 seconds. If the bacon has rendered plenty of fat, you can use less or omit the oil, but keep the heat moderate so the garlic does not scorch.
Simmer the sausage (20 minutes). Add the stock, bay leaves, and whole white sausages. Bring the pot just to a boil, then lower the heat to maintain a gentle simmer. Cook for about 20 minutes, turning the sausages once. Check the center of a sausage with a food thermometer: it must reach 160°F (71°C), the USDA FSIS safe minimum for ground meat. Remove the cooked sausages to a plate. While the soup simmers, boil the eggs in a separate pan until the yolk and white are firm, then cool them enough to peel. Keeping the eggs separate makes their doneness easy to judge and prevents them from breaking up in the soup.
Cook the potatoes (13 minutes). Add the cubed potatoes to the simmering stock and cook until just tender when pierced with a fork, about 13 minutes. Keep the soup at a gentle simmer rather than a rolling boil; vigorous boiling can break up the potatoes and make the broth cloudy. While they cook, slice the sausages into bite-size rounds once they are cool enough to handle.
Add the rye starter and season (5 minutes). Stir the żurek zakwas well, since rye flour can settle in the bottle, then pour it into the pot. Add the marjoram, salt, and pepper. Return the sliced sausage to the soup and simmer gently for 5 minutes, stirring once or twice. Do not boil hard after adding the fermented starter. Taste a spoonful and adjust the salt or pepper; the starter’s sourness and salt level vary by maker. Stir in the optional horseradish if you want a sharper finish.
Fill and serve the bread bowls. Cut each peeled egg in half. If you want firmer bread bowls, set them on a baking sheet and warm them in a 350°F (175°C) oven for 8–10 minutes while the soup finishes; this optional warming time is not included in the 1 hour 15 minute recipe total. Ladle the hot soup into the bowls just before serving, making sure each portion has sausage and potatoes. Top with half an egg, a spoonful of sour cream, and dill. Serve promptly with the bread lids on the side.

Tips

Choose bread that can hold its shape. A crusty rye or sourdough round with a firm crumb is less likely to leak than a soft sandwich loaf. If you cannot find individual rounds, use one small boule, cut it into four thick portions, or serve the soup in bowls with toasted bread on the side.
Know your starter. Żurek zakwas is fermented rye starter, not ordinary sourdough discard. Bottled zakwas is the easiest option; shake or stir it before measuring. If you find packaged żurek soup base instead, follow its label and reduce added salt because concentrates are often already seasoned. Plain vinegar or lemon juice adds sharpness but does not reproduce the fermented rye flavor.
Keep the soup gently simmering. A hard boil can split the sausage casing, break apart the potatoes, and make the starter taste harsher. If the broth seems too sour, add a little more stock; if it tastes mild, stir in a few extra tablespoons of zakwas and simmer briefly before serving.
Fill bowls at the last minute. Bread absorbs liquid quickly, especially at the cut edge. Set the bread bowls on individual plates or shallow dishes to catch drips, and keep extra soup in the pot until everyone is ready to eat.

Serving Suggestions

Serve each bowl as a substantial main course, with the egg, sausage, potatoes, sour cream, and dill distributed across the servings. A crisp, acidic side such as cucumber salad or a simple cabbage slaw gives the meal a fresh contrast to the rich broth. Pickled cucumbers or beets are also a good match, and the bread lids make handy pieces for dipping.

If you are serving a group, bring the soup to the table in a pot and let people choose between bread bowls and regular soup bowls. This is especially useful if someone prefers a smaller serving or if the loaves are not sturdy enough to hold soup for long. Put extra horseradish and sour cream on the table so each person can adjust the strength and creaminess to taste.

Variations

Fresh Polish white sausage gives the soup its familiar mild, savory character. If it is unavailable, use uncooked mild pork sausage and remove it from its casing if needed; the soup will remain similar, though it will not have the same Polish seasoning. Smoked kielbasa is another practical substitute, but because it is already cooked and smoky, slice it and add it with the potatoes rather than simmering it for the full sausage-cooking stage. Check the package directions and heat it through.

For a meat-free version, leave out the bacon and sausage, use vegetable stock, and brown sliced mushrooms in the pot before adding the onion. The result will be less smoky and meaty, so a little extra marjoram or horseradish can add depth. For a milder soup, start with 1½ cups (360 ml) of zakwas and add more to taste. You can also omit the bread bowls entirely and serve the soup with rye bread on the side; the broth and toppings are the same.

Storage and Reheating

For best texture, store the soup, eggs, and bread separately. Refrigerate the soup within 2 hours of cooking in a covered container; it keeps for 3–4 days. Refrigerate peeled eggs in a separate covered container, and keep unfilled bread rolls at room temperature in a bread bag for a day or two, according to their freshness. Do not refrigerate soup inside the bread bowls, since the bread will become soggy.

Reheat only the amount of soup you need in a saucepan over medium-low heat, stirring occasionally, until it is steaming throughout and reaches 165°F (74°C), the USDA FSIS safe temperature for leftovers. Avoid a vigorous boil. Warm bread bowls separately in a 350°F (175°C) oven for a few minutes if they are still fresh. Add sour cream and dill after reheating. The soup can be frozen in a freezer-safe container for about 2–3 months for best quality, though the potatoes may soften; thaw it in the refrigerator before reheating to 165°F (74°C).

Frequently Asked Questions

What is Polish soup in bread called?

The soup is usually żurek, also spelled zurek, a Polish sour rye soup made with fermented rye starter. Serving it in a hollowed bread loaf is a popular presentation, but żurek is just as often served in a regular bowl. The bread bowl is a serving style rather than a different soup.

Can I make żurek without bottled rye starter?

Yes, but the flavor depends on what you use. Look for fermented żurek zakwas in a Polish or Eastern European grocery shop, or use a packaged żurek soup base according to its instructions. Plain sourdough starter, vinegar, or lemon juice is not a direct substitute: each changes the flavor, and acid alone will not provide the fermented rye character.

Can I prepare the soup ahead of time?

Yes. Cook the soup a day ahead, cool it promptly, and refrigerate it in a covered container. Reheat it gently to 165°F (74°C) before serving, and prepare the bread bowls only when you are ready to eat. Keep the eggs and garnishes separate so the bread stays crisp and the toppings remain fresh.

How do I keep a bread bowl from leaking?

Start with a dense, crusty roll rather than a soft roll, and leave a thick wall and base when you hollow it out. Warming the empty bowl in the oven can help dry the cut surface, but it cannot rescue bread with a weak crust or a very open, fragile crumb. Fill it immediately before serving and set it on a plate.

Is żurek supposed to taste sour?

Yes, its fermented rye starter gives it a pleasantly tangy flavor, though the strength varies between starters and regional or family recipes. Start with the measured amount, taste after simmering, and adjust gradually. A splash of stock can soften an overly sharp batch; adding more zakwas makes a mild pot tangier.
