This lighter version of the beloved soup gives you more flavor, less glop, and full hearty satisfaction. With one simple extra step, the standard mashed potato process leads to a creamy soup adorned with all the great baked potato toppings. If you like the idea of some chunks of potato, mash coarsely; for a smoother soup, mash more completely. For the best texture, stick with russet potatoes (aka baking potatoes); starchier varieties won’t yield as creamy a result. The soup reheats well, so it’s a good make-ahead candidate; just store the toppings separately.
