This Polish-style Sauerkraut Mushroom Buns recipe turns basic ingredients into mouthwatering savory treats that mix tangy fermented cabbage with rich mushrooms all wrapped in soft, fluffy yeast dough. These tasty buns, known as paszteciki or kapusniaczki in Poland, bring real Eastern European taste to your kitchen without any fancy cooking tricks.

I tried making these for a cold-weather party because I wanted something different than the usual chips and dip. They vanished almost instantly, and everyone kept asking me about the amazing flavor combo they hadn't tried before.

Ingredients

  • For the Sauerkraut Mushroom Filling
  • Sauerkraut: Gives that zingy taste that's the heart of Polish food
  • Dried porcini mushrooms: Pack a powerful earthy punch that makes the filling special
  • Fresh cremini mushrooms: Add heartiness and help balance the sauerkraut's tang
  • Onions: Slowly browned to bring out natural sweetness that softens stronger flavors
  • Caraway seeds: Give that real Polish taste with their unique fragrant flavor
  • Marjoram: Brings a fresh herb note that works well with earthy elements
  • For the Yeast Dough
  • All-purpose flour: Makes a soft but strong wrapper for your filling
  • Instant yeast: Gets your dough rising without extra steps
  • Butter: Makes the dough taste amazing and creates that can't-resist texture
  • Eggs: Add richness and help the buns turn beautifully golden

Simple Cooking Steps

Start With The Filling Basics:
Cook your drained sauerkraut with the dried porcini and spices until everything's nice and soft. This slow cooking brings all the flavors together while taking away that too-sharp sauerkraut bite. The leftover cooking liquid gets packed with mushroom goodness and makes awesome soup later on.
Build Your Flavor Foundation:
Cook those onions slowly with caraway seeds until they turn clear and sweet. This creates the base taste for your filling. Then brown your fresh mushrooms separately on high heat, letting them sit untouched at first to get really caramelized. Doing them separately means each part keeps its own special taste and feel.
Get The Filling Just Right:
Chop everything up fine but don't turn it into mush. Your filling should have some texture but still stick together when you put it on the dough. Only add salt and pepper after everything's mixed since sauerkraut already brings plenty of flavor.
Mix Up That Soft Dough:
Start your dough with warm milk to wake up the yeast. Then work the butter in bit by bit after the dough has formed - this makes layers of softness you can't get if you throw everything in at once. Taking your time with the butter is key for that perfect texture.
Form Your Buns Carefully:
Roll the dough out into a big rectangle and cut it into strips before adding your filling. Wrap everything tight so nothing leaks during baking. Let them rise again after shaping to get fluffy and develop more flavor.
Bake Them Golden Brown:
Brush with beaten egg to get that pretty shine. Make little cuts on top before baking so they'll break apart easily while staying moist inside. Watch for that golden color instead of just following the clock.

My grandma always spent at least ten minutes cooking those onions until they turned sweet. I tried to rush it once and the whole thing tasted awful. That slow cooking of the onions totally changes the filling from just okay to amazing by balancing out the sour sauerkraut perfectly.

Easy Prep Options

You don't need to make these all at once. The filling keeps in the fridge for three days if you want to get ahead. You can even put together the unbaked buns and keep them in the fridge overnight before their final rise. If you want to store them longer, bake them completely, let them cool down, and pop them in the freezer in sealed containers. When you're ready to eat, warm frozen buns in a 325°F oven for about 10-15 minutes.

Tasty Twists

The classic recipe works great as is, but you can always change things up. Try adding a spoonful of rinsed poppy seeds to the filling for a real Polish touch. Want something more filling? Toss in 4 ounces of crispy chopped bacon with the onions. Vegetarians might like adding 1/2 cup of cooked barley to the mix for extra chewiness and nutrition.

Ways To Enjoy

In Poland, folks eat these during Christmas celebrations or grab them as street food. Serve them warm with a dollop of sour cream for dipping as an appetizer. For a full meal, pair them with a simple cucumber and dill salad mixed with sour cream. They're also fantastic for breakfast alongside some scrambled eggs.

Food History

Sauerkraut and mushroom fillings run deep in Polish cooking, especially around Christmas when many people skip meat on Christmas Eve. Fermenting vegetables helped communities eat well through long, cold winters. When you make this recipe, you're connecting with hundreds of years of Eastern European cooking wisdom using methods that really work.

Frequently Asked Questions

→ Can I get the filling ready ahead of time?

Sure, you can make it the day before. Chill it in the fridge once cooled, so it's ready for use later.

→ How can I stop the dough from sticking?

Slight stickiness is normal. Try using a silicone mat or just lightly oil your hands and surface to help.

→ Can I swap in other mushrooms?

Absolutely. While porcini and cremini are great, button mushrooms or shiitake make good replacements too.

→ What does the egg wash do?

A quick egg wash gives the buns a shiny, golden look and a slightly crisped outer layer.

→ Is it okay to freeze baked buns?

Yes, you can freeze them. Cool them completely, then store in an airtight bag or container for up to three months.

→ What should I do with extra filling?

You can use leftover filling in pierogi, croquettes, or as a topping for toast or baked potatoes.

Ingredients

→ Mushroom & Sauerkraut Mixture

01 240g onions, medium-sized
02 3 tbsp oil for frying
03 2 dried bay leaves
04 450g sauerkraut, well-drained
05 1 tsp caraway seeds
06 2 allspice berries, whole
07 20g porcini mushrooms, dried
08 400g cremini mushrooms, fresh
09 Season with salt and black pepper
10 1 tsp dried marjoram

→ Dough with Yeast

11 400g plain flour, spooned & leveled
12 115g butter, very soft
13 240ml slightly warm milk
14 1 teaspoon fine salt
15 1 large egg, room temperature
16 1 packet + 1/2 tsp (9g instant yeast)
17 1 additional egg yolk, room temperature
18 1 tbsp white sugar

→ Extras

19 Milk (1 tbsp) + 1 egg, combined for wash
20 Caraway seeds for dusting

Instructions

Step 01

In a medium pot, combine the sauerkraut, dried porcini, bay leaves, and allspice berries. Pour in water to just cover everything and cook under a loose lid at medium heat for about 45 minutes. Once the sauerkraut turns tender, drain the mixture and toss the bay leaves and berries.

Step 02

Pour 2 tbsp of oil into a big pan and heat at a medium level. Toss in chopped onions and caraway seeds, stirring occasionally for around 10 minutes, until soft. Sprinkle in marjoram, cook for another 60 seconds, then set aside. Turn the heat up to high, add the remaining oil, and cook mushrooms without stirring for 2–3 minutes. Stir and fry until any moisture is gone and mushrooms brown up. Let cool.

Step 03

Combine the cooked sauerkraut, mushrooms, and onions in a food processor. Blend briefly until finely broken down but avoid turning it into paste. Alternatively, mince it all with a knife. Sprinkle with salt and pepper to your liking. Chill in the fridge until you need it.

Step 04

In a roomy bowl, toss together flour and salt. Heat milk to just warm (around 38–43°C), mix in sugar and yeast, and wait 10 minutes for foam to appear. Stir the yeast liquid, egg, and yolk into the flour mix, forming a rough dough. Slowly knead in softened butter bit by bit until it's well blended. Knead for 10 minutes. Shape the dough into a round, place it in a greased bowl, cover it, and let it grow in a cozy spot for an hour or until it doubles in size.

Step 05

Spread the dough into a 35x45cm sheet. Slice this into 4 strips lengthwise. Spoon the chilled filling down each strip’s middle, then fold the dough around the filling to create logs. Line a baking sheet with parchment, place the logs on it, cover lightly, and let them puff up for half an hour.

Step 06

Turn the oven on to 180°C to preheat. In a small bowl, whisk an egg and 1 tablespoon of milk for the topping. Brush the dough logs, slice 5cm openings halfway down along each log, and bake for 25 minutes until they’re golden all over. Enjoy warm!

Notes

  1. For easy dough handling, make sure the filling cools completely before assembly.
  2. Save the drained sauerkraut liquid — it packs a punch in hearty soups like beet soup.
