Cook the Bacon: In a large Dutch oven over medium heat, cook the chopped bacon until crispy (5–7 minutes). Transfer to a paper towel-lined plate, leaving the drippings in the pot.
Brown the Kielbasa: Add sliced kielbasa to the bacon drippings and cook until browned (3–5 minutes). Remove and set aside with the bacon. Drain excess drippings, leaving about 1 tablespoon.
Sauté the Beef and Aromatics: Add ground beef, onion, and garlic. Cook, breaking the meat apart, until browned and onions are soft (5–7 minutes).
Add Spices and Thickener: Stir in flour, chili powder, cumin, salt, and pepper. Cook for 1–2 minutes until the flour is absorbed and smells toasty.
Build the Stew: Pour in chicken broth, beans (with liquid), corn, diced tomatoes (with liquid), and potatoes. Stir well, scraping up browned bits. Return bacon and kielbasa to the pot.
Simmer to Perfection: Bring to a boil, then reduce heat to medium-low. Cover and simmer for 1 hour, stirring occasionally, until potatoes are fork-tender.
Serve: Ladle into bowls, garnish with parsley, and serve hot with crusty bread or cornbread.
