This post is sponsored on behalf of #FallFlavors. Our generous sponsors Melissa’s Produce and Nairn’s Oatcakes  have provided me complimentary products for recipe creation and a giveaway for our readers. As always, all opinions are my own.

Sweet Potato Gratin is my recipe of the day with #FallFlavors week. This is not your usual marshmallow topped overly sweet casserole. And that is always a good thing.

Instead, this  gratin has thin slices of sweet potato. Those are in a buttery cream sauce flavored with Parmesan cheese. And topped with crisp  oat crumbs. It is very much a wholesome and hearty comfort food dish.

Perfect for your  autumn family dinners. Together with an entree and salad, it is a complete meal.

In addition to weekday  meals, it can be a great side dish for  a holiday  spread.

Potatoes are lined up on their edges in  a circular pattern. Then they are topped with buttery  cream and cheese. And covered and baked until tender.

Once it  is  baked, it is time to add the buttered crumbs which  quickly brown  for a nice crisp  topping.
