A hearty and flavorful casserole combining seasoned beef, vegetables, and creamy mashed potatoes, topped with melted cheese.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated for even cooking.
In a skillet over medium heat, cook the ground beef and diced onion until the beef is browned and the onion is softened. Drain any excess fat.
Use a wooden spoon to break up the beef for even cooking.
Stir in the tomato sauce, minced garlic, and oregano. Cook for an additional 2-3 minutes to blend the flavors.
Taste and adjust seasoning if needed.
Transfer the beef mixture to a casserole dish, spreading it evenly.
Press the mixture down gently for a firm base.
Evenly distribute the corn over the beef mixture.
Ensure the corn covers the beef layer completely.
Spread the mashed potatoes over the corn layer, smoothing the top.
Use a spatula to create an even layer.
Sprinkle the shredded cheddar cheese over the mashed potatoes.
For extra cheesiness, add a bit more cheese.
Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly.
Check halfway through to ensure even baking.
Let the casserole cool for a few minutes before serving. Enjoy!
Garnish with chopped parsley for a fresh touch.
