This Polish Kapusta is a delicious family recipe perfect for any occasion. It's an easy slow cooker kielbasa and sauerkraut dish, combining hearty flavors with minimal effort.
In a large skillet, melt butter and bacon drippings over medium heat until foaming subsides, about 2-3 minutes.
Add onions and cook, stirring occasionally, until onions are translucent and edges begin to brown, about 8-10 minutes.
While onions cook, rinse and drain sauerkraut at least twice. Make sure the sauerkraut is well drained.
Add the sauerkraut to a slow cooker along with onions, salt, pepper, brown sugar, water, and kielbasa. Give everything a good stir and cover.
Cook on high for 1 hour, then reduce to low and cook for an additional 6 hours, stirring occasionally. Serve.

Notes
My dad distinctly remembers his mom using bacon drippings that she would keep in the refrigerator for this recipe. If you don't have any on hand, substitute two additional tablespoons of butter (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.
