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 slow cooker. Evenly layer the diced potatoes, kidney beans, corn, and diced tomatoes over the beef.
03 - In a small bowl, whisk together the condensed mushroom soup, beef broth, smoked paprika, garlic powder, oregano, black pepper, and salt until smooth.
04 - Pour the sauce mixture evenly over the layered ingredients. Cover and cook on LOW for 6 hours, until potatoes are fork-tender.
05 - Sprinkle shredded cheddar cheese over the top during the last 15 minutes of cooking. Cover until melted. Serve hot, garnished with fresh parsley or green onions if desired.
