Preheat oven to 375. Spray your casserole dish with nonstick cooking spray.
In a large bowl, mix all ingredients together except for 1 cup of the cheese. Stir until ingredients are well combined. Add salt and pepper to taste.
Pour mixture into your greased casserole dish and top with remaining cup of cheese.
Bake casserole uncovered in oven for 45 - 55 minutes or until cheese is bubbly and center is heated through.
Remove from oven and serve immediately.
Notes
This recipe can easily be doubled or halved
You can use any cream soup that you have in your pantry or that you like
I use one small bag of hash browns in mine, since the size of bag varies so much depending on my store or the brand available that's why I have such a large range for the size. Use whatever you can find.
If your bag is on the larger end of the spectrum, you may want to add a little more sour cream or cheese if you want more of a gooey texture to your casserole.
