Kittencal's Scalloped Potato and Ground Beef Casserole

Sliced potatoes in a delicious creamy sauce on the bottom then topped with a ground beef mixture --- instead of layering the potatoes you can just mix them with the sauce in a large bowl transfer to the baking dish then top with the ground beef mixture either way is fine but the potatoes will cook a little faster if mixed with the sauce --- feel free to throw in some cooked chopped green beans, mushrooms, corn niblets to the ground beef mixture or whatever you wish, I also like sprinkle some grated cheddar cheese over the potato mixture before topping with the ground beef and then again after the casserole has been cooked, this casserole is very versatile and you don't have to worry about the exact amounts --- to save time you may cook the ground beef mixture a day ahead and refrigerate, all ingredients may be reduced to half if desired to yield 4-6 and baked in a smaller baking dish--- NOTE some of the reviewers are stating that the potatoes are taking a long time to cook so you may want to pop them in the microwave first just to soften slightly,
