Place the beef stew meat, potatoes, onion, garlic, paprika, bell pepper, tomato paste, and caraway seeds into the slow cooker.
Pour in the beef broth and add salt and black pepper to taste.
Stir everything together until the ingredients are evenly combined.
Cover and cook on low for 8 hours or on high for 4 to 5 hours, until the beef is fork-tender.
Ladle the stew into bowls and top each serving with a spoonful of sour cream and a sprinkle of chopped parsley.
