In a large skillet over medium heat, brown the ground beef. Use a spatula to break it up into small pieces as it cooks. Cook until fully browned, about 6-8 minutes. Drain excess fat if necessary.
Add the diced green bell pepper and onion to the skillet. Sauté for about 5 minutes, until the vegetables are tender.
Stir in the diced potatoes, corn, cream of mushroom soup, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix well to combine everything evenly.
Transfer the mixture into a greased 9x13 inch baking dish, spreading it out evenly.
Cover the baking dish with aluminum foil and bake in the preheated oven for 35 minutes.
After 35 minutes, remove the foil and sprinkle shredded cheddar cheese evenly on top. Return the casserole to the oven and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly, and the potatoes are tender.
Once done, remove from the oven and let it sit for a few minutes before serving. Garnish with freshly chopped parsley.
Notes
Serve in individual bowls and sprinkle with additional parsley for a pop of color. You can accompany it with a side salad or some crusty bread for a complete meal.
