Traditional Sauerkraut and Kielbasa

My dad is 100% Polish, and he 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 decided to make our family Kielbasa Kapusta recipe for him, but with my twist!

I kept all of the ingredients and quantities the same, but decided to cook it in the crockpot! It’s way more convenient for my lifestyle, and I know so 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 flavor of the dish 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 treat we can pass forward to generations to come!

Kielbasa and Sauerkraut Crockpot ingredients

  • 2 Tablespoons butter
  • 2 Tablespoons bacon drippings
  • 2 ½ cups sweet yellow onions finely chopped

How to season Kielbasa

Seasoning kielbasa is a simple and delicious way to enhance its flavor. Start with fresh or smoked kielbasa. If you’re using fresh kielbasa, you can cook it as is. Add some flavor to the smoked kielbasa by brushing it with olive or vegetable oil. While kielbasa is already flavorful, add extra seasonings to suit your taste preferences. Popular seasonings for kielbasa include black pepper, garlic powder, paprika, onion powder, mustard powder, and caraway seeds.

How to make Kielbasa and Sauerkraut

  1. First, melt the butter and bacon drippings until foaming stops in a large skillet for a couple of minutes.
  2. Next, add onions and cook, occasionally stirring, for about 8 minutes.
  3. Then, drain the sauerkraut at least twice, ensuring it is well-drained before putting it in the crockpot.
  4. Next, add the onions, salt, pepper, brown sugar, water, and kielbasa in the crockpot. Stir everything before you cover it and cook on high for 1 hour.
  5. Finally, reduce to low and cook for an additional 6 hours, stirring occasionally. Serve and enjoy!

Kapusta Recipe Cook’s Note

  • My dad distinctively remembers his mom using bacon drippings that she would keep in the refrigerator for this recipe. If you don’t have any on hand, then substitute two additional tablespoons of butter (for a total of 4 tablespoons) for the bacon drippings.
  • I like to serve this dish with mashed potatoes (this recipe is SO good!). After all, potatoes, kielbasa, and cabbage are the holy trinity of Polish cuisine!
  • This recipe is even MORE flavorful the next day! I know hard to believe, right?!
  • My family likes to eat leftovers between toasted Kaiser rolls with grainy mustard.

How to serve this Kielbasa 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! If you’re going to make it a complete Polish meal, then serve this along with my Polish Beet Soup
