In a large pot or Dutch oven, cook the chopped bacon over medium heat until crisp. Remove bacon bits with a slotted spoon and set aside, leaving the rendered fat in the pot.

Add the sliced kielbasa to the hot fat and brown on both sides, about 5 minutes. Remove and set aside with the bacon.

Add the chopped onion and sliced mushrooms to the pot. Sauté for 5-7 minutes until the onions are translucent and mushrooms are browned.

Stir in the fresh shredded cabbage and cook for another 5 minutes until it begins to wilt significantly.

Add the drained sauerkraut, tomato paste, caraway seeds, and smoked paprika. Stir well to coat the vegetables.

Pour in the beef broth and return the cooked kielbasa and bacon to the pot. Stir to combine.

Bring the mixture to a simmer, reduce heat to low, cover, and cook for 25-30 minutes to allow flavors to meld and cabbage to tenderize.

Taste and season with salt and pepper as needed (be careful with salt as the meats and sauerkraut are salty).

Garnish with fresh parsley and serve hot with crusty bread.
