It’s November which means that it’s Thanksgiving season! If you are a long time reader, you know that I have some pretty specific ideas when it comes to our Thanksgiving dinner menu. Our family has some traditional recipes that we don’t really stray from but usually bring a new dish or two to sample.

Over the last few years, I have posted all of my Ultimate Thanksgiving recipes: Bacon Herb Oven Roasted Turkey, Sausage Filling,  Roasted Garlic Herb Cream Cheese Mashed Potatoes, and Cranberry Marshmallow Relish.

There has been one exception: Sweet Potato Casserole.

Marshmallow Sweet Potato Casserole

While I shared my twice baked sweet potatoes recipes a few years back, I have never shared my family’s favorite sweet potato casserole. My sister-in-law is typically in charge of the sweet potatoes and that is the recipe that I always go to when making sweet potato casserole. Her recipe includes a candied pecan topping and this year, I decided to add some Campfire® Mini White Marshmallows to the pecans.

Who doesn’t love sweet potato casserole with mini marshmallows? Add some brown sugar, butter, and pecans and this marshmallow pecan sweet potato casserole is a total winner. The sweet potatoes are creamy, sweet, and when baked in a large casserole dish, each bit gets just the right amount of topping per scoop.

The topping is very coveted.

It’s a simple dish to make, but will make your entire family happy!
