A delightful casserole combining ham, potatoes, and cheese for a comforting meal.
Preheat your oven to 375°F (190°C).
Ensure the oven is fully preheated for even cooking.
Lightly grease a 9x13 inch baking dish.
Use a non-stick spray or a small amount of butter.
In a large mixing bowl, combine the hash brown potatoes, diced ham, sour cream, cheddar cheese, and cream of mushroom soup.
Mix thoroughly to ensure even distribution of ingredients.
Transfer the mixture into the prepared baking dish and spread evenly.
Smooth the top with a spatula for even cooking.
Sprinkle the grated Parmesan cheese evenly over the top.
Ensure the topping is evenly distributed for a consistent crust.
Bake in the preheated oven for about 60 minutes, or until the top is golden and the casserole is bubbling.
Check halfway through to ensure even cooking.
Let the casserole cool slightly before serving.
Allowing it to cool helps the flavors settle and makes serving easier.
