Having a smaller Thanksgiving dinner and don’t need a sweet potato and a mashed potato option? Just want more flavor than the traditional options? These are for you!! We make these for Thanksgiving, steak night and so much more.

I was a little weary of mixing the two potatoes when I first made this dish a few years back but you will not regret it. It brings the sweet and the savory together perfectly.
