Ingredients:

1 cup milk
3/4 cup sour cream
3/4 cup butter, melted
1/3 teaspoon seasoning salt
1 teaspoon ground black pepper
1 teaspoon garlic powder
1/4 cup Parmesan cheese, plus extra for topping
2 cups shredded cheddar cheese
1 onion, diced
2 green onions, thinly sliced
2-3 cups frozen hash browns

Instructions:

Preheat Oven: Set your oven to 350°F (175°C) to preheat while you prepare the casserole.
Prepare Casserole Dish: Grease a 13×9-inch casserole dish generously with butter to prevent sticking.
Mix Ingredients: In a large mixing bowl, combine the undiluted soup, milk, sour cream, melted butter, seasoning salt, black pepper, garlic powder, and 1/4 cup of Parmesan cheese. Whisk or mix thoroughly until all ingredients are well combined.
Incorporate Cheese and Onions: Add the shredded cheddar cheese, diced onion, green onions, and frozen hash browns to the mixture. Stir until everything is evenly distributed.
Transfer to Baking Dish: Spread the mixture evenly into the prepared casserole dish, ensuring it is spread out uniformly.
Top with Cheese: Sprinkle an additional 1/2 cup of Parmesan cheese over the top of the casserole for an extra cheesy crust.
Bake: Place the casserole dish in the preheated oven, uncovered, and bake for approximately 40 minutes, or until the casserole is hot and bubbly, and the top is golden brown.
Optional Cheesy Finish: For an added layer of cheesy goodness, sprinkle an additional 2 cups of grated cheddar cheese over the top of the casserole during the last 3 minutes of baking. Return the casserole to the oven just until the cheese is melted and gooey.
Serve and Enjoy: Once baked to perfection, remove the casserole from the oven and allow it to cool slightly before serving. Slice into generous portions and watch as your family and friends devour this delectable dish with delight.

Tips and Variations:

Make Ahead: This casserole can be prepared ahead of time and refrigerated until ready to bake, making it a convenient option for busy days or entertaining guests.
