Amy, buy a couple boxes of Betty Crocker Scalloped potatoes (or the Au Gratin ones) - prepare as directed on the box, and add two bunches of green onions, chopped, with ends. Bake as directed.
This my son’s VERY favorite scalloped potatoes dish - and he almost devoures the whole dish~!
I have tried these yorkie and I agree they are delicious! My SIL makes the old fashioned kind and she makes 2 casseroles for Thanksgiving and Christmas because my brother loves them so. I have never suggested the Betty Crocker’s to them, as they are very set in their ways. I am pretty sure she told me she uses 8 potatoes for each casserole. Thats a lot of peeling and slicing into nice rounds!
When I cook for just me I use those. I warm over the rest the next day or whenever!
