This is the only casserole my husband likes. I got the recipe from his mother then started to tinker with it. It's a Depression-Era recipe and Marian noted that one could dot with butter if one didn't have cheese. Marian's "measurements" were pretty vague. Over time, mine have become vague, too! This is a very flexible and tolerant recipe, so feel free to add, subtract, and adjust according to your tastes.
You can prepare this ahead of time and bake it the day you plan to serve it. It also makes terrific leftovers.
I like to serve this with broccoli and garlic bread.
I miss Marian and I'm glad I can remember her with this recipe.
