Golden, cheesy, and with that hint of ham, this Duchess Gratin Potato Slab is a great addition to your dinner table.

The flavor of loaded potatoes, the texture of classic Duchess spuds and the look of slab pie. Did I mention it’s easy as well? Using leftover mashed potatoes is also perfectly suitable for this preparation!
