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