Necessary ingredients:
First, brown the sausage!
Then, mix the sausage to the frozen hash browns and add some cheese!
I like to use the hot Italian sausage in this case because I feel it really adds a nice kick to the finished casserole. Mmm!
Mix everything together and pour into a 9x13 casserole dish. Bake covered for approximately 30 minutes and then uncovered until the top browns slightly (or until you think it's done ... there's plenty of room for adjustments)!
The biscuits are an optional but tasty addition, especially if you put the mixture inside the biscuit like a breakfast sandwich!
