Breakfast Sausage – So I used sausage for this breakfast bake. But, you can swap with Canadian bacon, bacon, etc. Just make sure the meat is fully cooked before you mix in the casserole.

Hashbrowns – I used diced hashbrowns that I got in the freezer section at our grocery store.

Cheese – Cheddar cheese is a great pairing, Monterey Jack, or even a sharp cheddar can be used. Or spice it up with pepper jack cheese.

Seasonings – Garlic powder, onion powder, and salt and pepper are used for seasoning.

Milk – The milk is going to help allow the eggs to become fluffy as it bakes up.
