Traditional Sauerkraut and Kielbasa
My dad is 100% Polish and has been talking about his grandmother’s and mother’s Kielbasa Kapusta for decades! When my Polish grandmother passed away when I was 17, I inherited a couple of her cookbooks and her recipe tin.
That recipe tin has produced fabulous gems over the years. To surprise my dad on a recent trip back home, I made our family Kielbasa Kapusta recipe for him, but with my twist! I kept the ingredients and quantities the same, but I decided to cook it in the crockpot! It’s way more convenient for my lifestyle, and I know many of you will find this cooking method helpful, too!
Another change I made was to cut the kielbasa pieces smaller. This method enhanced the dish’s flavor by releasing more of the kielbasa juices, AND it allowed more surface area for the kielbasa to soak up the Kapusta juices! Is your mouth watering yet?! While the Kielbasa Kapusta was cooking, my dad snuck into the kitchen more than once with a huge, nostalgic grin on his face, saying, “This smells familiar,” and “Ooohhhh weeeee, is it dinner time yet?”
While I never tasted my grandmother’s version, my dad thought I pulled off a near match. I am so glad I found and tried this recipe, which gave my dad and me another link to our family heritage and produced a heartwarming dish we can pass to generations to come!

What is kielbasa?
Kielbasa is a staple in any Polish home. It is a type of sausage. In the USA, it is best known as any U-shaped meat with a coarse texture.

How to serve this Kielbasa Kapusta Crockpot Recipe
Kapusta means cabbage, so when serving this recipe of cabbage and Kielbasa (sausage), potatoes are a great option. These crispy smashed potatoes are seriously one of my all-time favorite potato recipes. For a classic choice, check out these creamy buttermilk mashed potatoes. But if you are like me and need more cheese in your life, you will want to make these 3-cheese potatoes Au gratin!

Kielbasa Kapustka Recipe FAQs
Kapustka is a surname in the Polish language, and its literal translation is “cabbage.”
The word “kapusta” is of Slavic origin and is used in several Slavic languages, including Polish, Ukrainian, Russian, and others, to refer to “cabbage.”
In German, the word for “cabbage” is “Kohl” or “Weißkohl” (white cabbage) for the specific type of cabbage. The term “kapusta” is not used in the German language.
No, it would be best not to poke holes in the kielbasa before cooking. Poking holes in the sausage can cause the flavorful juices and fats to escape, leading to a drier and less tasty result.

I am really gonna try this one. I’m from the Netherlands and I looks so much like a real dutch meal we called zuurkool stamppot (mashed sauerkraut) that’s with sauerkraut, mashed potatoes, bacon mixed together, with smoked sausage called in Dutch rookworst. We mostly eat it in the winter
I’ve been making Kapusta for years. My recipe is about the same. I do add sliced potatoes as a filler, and shredded carrots for color. Always make perogies to go with. One of my favorite meals, and everyone lives it.
Can you brown the meat a bit under a broiler to enhance flavor?
Yes, you can brown the kielbasa under a broiler to enhance its flavor. This can add a nice caramelization and deepen the taste of the dish. After slicing the kielbasa into pieces, place them on a baking sheet and broil for a few minutes until they are browned to your liking, then proceed with the rest of the recipe.
