The combination of red and white potatoes were great. I have made these twice. The first time I just served them right after mashing. Both ways, these potatoes are great.

This is a very tasty potato casserole. I scaled the potatoes by half but used the stated amounts of cream cheese, sour cream and cheese (cheddar and Parmesan). Love the texture and the cheesiness. Thanks for posting.
