I have never made this, but if I were going to make potato soup, it would have to be a copycat of Outback's, which I really love (found this:

But my DH has decided he no longer eats white potatoes, so if I made it, it would have to be for myself....
The chunky tomato potato soup above sounds good, but it's not what I think of when I think of potato soup.
