Scalloped/Au Gratin Homestyle Casserole

No ... this is not how to make it from scratch.  This is cooking time adjustments for the boxed Idahoan casseroles.  I have no shame in my love for these, none whatsoever.  I can throw down on some pommes anna and other fussy potato dishes, but these are fast, easy and tasty.  I love these boxed franken-potatoes and I don't care who knows!!!

Best for Golden Browning

2. STIR in 1 1/2 cups boiling water, 3/4 cup milk, and 1 Tbsp. margarine or butter with whisk.
