Kapuśniaczki are little Polish pasties filled with sauerkraut and mushrooms, and they’re a firm favourite around Christmas in our house. The dough bakes up golden and soft with a gentle sweetness that sits beautifully against the tangy, savoury filling inside.
They’re the classic partner for a bowl of barszcz (Polish beetroot soup), handed round warm while everyone waits for the main meal. You can make the sweet dough from my recipe, or reach for shop-bought puff pastry when you’re short on time - both work well. Serve them alongside my Barszcz - Polish Beetroot Soup.

What Are Kapuśniaczki
Kapuśniaczki are little Polish pasties filled with sauerkraut and mushrooms, a classic pairing that sits right at the heart of Polish cooking. They turn up at Christmas next to a bowl of barszcz, but they are just as good as a snack any time of year. You can use different doughs, but I like an enriched, slightly sweet one, it plays beautifully against the tangy filling.
Kapuśniaczki Filling Ideas
The filling of Kapuśniaczki is what truly sets them apart, offering both versatility and depth of flavor. The classic vegetarian version features a savory combination of sauerkraut, mushrooms, and onions. The tanginess of sauerkraut balances perfectly with the earthy notes of mushrooms, while sautéed onions bring a subtle sweetness that ties everything together.
For an even more aromatic and robust filling, consider adding wild mushrooms like porcini or chanterelles. Wild mushrooms introduce a deeper, woodsy flavor that takes this humble dish to the next level. Many families in Poland forage for mushrooms during the autumn months, preserving them for dishes like this throughout the year.
While the vegetarian version is the most traditional, some households prefer a meatier twist by incorporating minced pork or beef into the filling. The richness of the meat pairs beautifully with the sauerkraut and mushrooms, creating a heartier, more indulgent version of Kapuśniaczki. If you’re using meat, browning it with the onions and seasoning generously with salt, pepper, and a pinch of marjoram ensures a perfectly balanced flavor.
For a subtle burst of flavor, you can also add a dash of caraway seeds or a hint of smoked paprika, both of which complement the sauerkraut filling beautifully.
If you stick to the vegetarian classic or explore a meat-filled variation, the filling is what makes Kapuśniaczki such a much-loved and customizable Polish dish. Each bite is packed with flavor, making it an tempting addition to any festive table or a comforting snack for cozy days.
Chef’s tip: the filling is where the flavour lives. Use good mushrooms and brown them well, squeeze the sauerkraut really dry so there is no watery cabbage, and season it a touch more boldly than you think - the pastry mutes the flavour, so a filling that tastes just right on its own can end up bland once baked.

Kapuśniaczki - Polish Sauerkraut & Mushroom Pasties
Equipment:
- Colander
- Hybrid Non Stick Frying Pan
Ingredients:
For the filling:
- 1.5 lbs Sauerkraut - (700g)
- 2 cups Hot water - (500ml)
- 0.66 lbs Brown or white mushrooms - (300g) cut in half and sliced (wild mushrooms can also be added to the mix)
- 3 Red Onions, medium size - (300g) finely sliced
- 2 tbsp Vegetable Oil
- 1 tsp Butter
- 2 Bay leaves
- 3 Allspice berries
- Salt and Black Pepper to taste
For the dough:
- 4 cups Plain flour - (500g)
- 1 pinch salt
- ¼ cup Granulated sugar - (50g)
- 2 oz Butter - (60g)
- ½ cup Milk - (130ml)
- 3 tbsp Water - (40ml)
- 1 oz Fresh yeast - (30g) or 0.5oz (15g) active dry yeast
- 3 Eggs - 2 for the dough and 1 for the brushing
- 2 tsp Caraway - seeds for topping
Instructions:
Preparing the Kapuśniaczki Filling:
- Begin by simmering the sauerkraut in a large pot with the bay leaves, allspice berries, and water. Cover with a lid and let it cook for about an hour. After cooking, drain the sauerkraut, remove and discard the spices, then allow it to cool. Finely chop the sauerkraut.
- While the sauerkraut is simmering, heat 2 tablespoons of oil in a medium-sized frying pan. Add the onions and cook over medium heat until they start to soften, about 5 minutes. Then, add the mushrooms, increase the heat, and cook until they are browned and fully cooked. Finish by stirring in 1 teaspoon of butter, and season with salt and black pepper to taste.
- Combine the chopped sauerkraut with the cooked mushrooms and onions. Adjust the seasoning to achieve a balance of salty, sour, and a hint of sweetness from the onions.
Preparing the Kapuśniaczki Dough:
- In a small saucepan, gently heat the milk and butter until the butter melts. Transfer this mixture to another container and add 3 tablespoons of cold water to cool it down. Dissolve the fresh yeast in this mixture and set it aside.
- In a large mixing bowl, combine the flour, a pinch of salt, and sugar. Add the yeast mixture and 2 eggs. Mix until well combined. The dough will be sticky; avoid adding extra flour. Let the dough prove in the bowl until it triples in size, which should take about 1 to 1.5 hours.
- Once the dough has risen, preheat the oven to 330°F (165°C). Divide the dough into 10 equal portions, each weighing about 3 ounces. Roll each portion into a 6-inch square (16 cm). Make five 1.2-inch (3 cm) cuts on both the left and right sides of the square. Place about 3 ounces (80g) of filling in the center of each square. Braid the dough by alternating strips from each side over the filling. Brush each pasty with beaten egg and sprinkle with caraway seeds.
- Bake the pasties on a baking tray lined with parchment paper for about 20 minutes. They may need to be baked in batches or on separate trays to ensure enough space for expansion.
- Once baked, transfer the pasties to a cooling rack. They are best enjoyed warm but can also be reheated in the microwave. Serve with a cup of beetroot soup. Enjoy your homemade Kapuśniaczki!

Regional Names and Combinations
In Poland, Kapuśniaczki are sometimes referred to as “Paszteciki” in different regions. While both are savory pastries filled with sauerkraut, mushrooms, or meat, Paszteciki are typically smaller in size and often shaped into bite-sized rolls or crescents. These petite versions are a popular choice for gatherings and festive celebrations, as they are easy to serve and enjoy.
Both Kapuśniaczki and Paszteciki are traditionally paired with a steaming bowl of barszcz czerwony (beetroot soup). This combination is a staple in Polish cuisine, especially during Christmas Eve (Wigilia) dinners and other special occasions. The rich, tangy filling of the pastry beautifully complements the slightly sweet, earthy flavor of the beetroot broth. Together, they create a comforting and flavorful experience that captures the essence of Polish culinary traditions.
While this pairing is most common during the holidays, it’s enjoyed throughout the year, particularly as a hearty snack or appetizer. If you’re new to Polish cuisine, starting with this classic combination is highly recommended. The contrast of the flaky, savory pastry with the smooth, velvety soup is simply unforgettable.
So, grab a plate of Kapuśniaczki or Paszteciki, pour yourself a warm bowl of borscht, and enjoy a taste of Poland’s rich culinary heritage. Smacznego!
