You may have the prettiest and freshest mushrooms in the world:
and
and
. . . but if you don’t have a can of Cream of Mushroom soup (preferably one, like this one, that’s “Great for Cooking”) . . .
. . . you can’t make a proper Midwestern mushroom casserole. And with its various additions, this one is still very improper.
Yum!
