I guess it all depends upon the mood I am in and how one wishes to define a casserole.
Love scalloped potatoes with Parmesan cheese.
Can make a great potato casserole with cheese and ham.
....I'll show you mine
I make a standard ham/scallop potatoes, straight out of Bettey Crocker, bechemel sauce, cooks thirty minutes covered and one hour uncovered. Well, 30 years ago, I decided to top it with grated cheddar cheese and Pepperidge Farm herb seasoned dressing in the final thirty minutes. My boys think that's the greatest think since Christmas. It is reallly good. And yours...
