Easy Fancy Scalloped Potatoes

Easy fancy scalloped potatoes are the perfect mix of creamy and crunchy. The thinly sliced potatoes are cooked in a creamy cheese sauce standing on their sides so the tops get extra crispy.

This recipe combined with a re-shoot of my Mom’s refrigerator overnight mashed potato recipe is the reason I ate potatoes for lunch for about a week straight. Not only did I cook all the potatoes; I cooked up a stuffing recipe as well. I was on top of my holiday recipes this year. Unfortunately I didn’t plan to cook a turkey or pot roast.

It was just sides for us.

I actually prefer Thanksgiving sides to the turkey anyway.

There is more variety.

Let the carnivores fight it out over who gets the last of the white/dark meat and go ham on the sides—that’s my holiday dinner motto. 

The idea for this recipe came from one of my favorite side dishes, hassleback potatoes. A potato is sliced 3/4 of the way down, like an accordion, baked, and stuffed with cheese or butter and veggies. The tops of the potatoes get nice and crispy while the lower half of the potato stays fluffy and creamy.

Easy fancy scalloped potatoes are cooked under the same premise. Arrange the thinly sliced potatoes on their sides, coat in cheese sauce, and then bake. They look super fancy and taste even better than the regular standard scalloped potatoes you might be used to.

My Thanksgiving isn’t complete without my favorite mashed potatoes. However, I would be willing to skip them for a year with a plate of easy fancy scalloped potatoes in front of me.

Sorry mom.
