01 - Heat a large skillet over medium heat. Add ground beef and diced onion. Cook until beef is browned and no longer pink, breaking apart with a spoon. Drain excess fat.
02 - Transfer the beef mixture to the base of a slow cooker.
03 - Arrange diced potatoes, kidney beans, corn, and diced tomatoes in even layers over the beef mixture.
04 - In a small bowl, whisk together condensed cream of mushroom soup, beef broth, smoked paprika, garlic powder, dried oregano, black pepper, and salt until smooth.
05 - Pour the soup mixture evenly over all ingredients. Cover and cook on LOW setting for 6 hours, or until potatoes are fork-tender.
06 - During the final 15 minutes of cooking, sprinkle shredded cheddar cheese over the top. Cover and allow cheese to melt completely.
07 - Serve hot. Garnish with fresh chopped parsley or sliced green onions if desired.
