01 - Heat a large skillet over medium heat. Add the ground beef and diced onion. Cook, breaking up the meat, until browned and no longer pink. Drain excess fat.
02 - Transfer the beef mixture to the bottom of a slow cooker.
03 - Evenly layer the diced potatoes, kidney beans, corn, and diced tomatoes over the beef mixture.
04 - In a small bowl, whisk together the condensed mushroom soup, beef broth, smoked paprika, garlic powder, oregano, black pepper, and salt until smooth.
05 - Pour the soup mixture evenly over all ingredients in the slow cooker. Cover and cook on LOW for 6 hours, or until potatoes are fork-tender.
06 - During the last 15 minutes of cooking, sprinkle shredded cheddar cheese over the top. Cover and let melt. Serve hot, garnished with fresh parsley or green onions if desired.
