This is what the casserole will look like before baking.
Be careful adding salt to this dish. The cream of mushroom soup is generally salty enough. This is a flexible recipe where you can add ingredients or substitute cream of chicken soup for a different flavor. Bacon, smoked sausage and more mushrooms are good additions. We also use different cheeses for the body and top occasionally.
We use a hand mandolin like this to slice the potatoes and onions that makes it easy and we can control the thickness.
