Slow Cooker Sweet Potato Casserole

Let’s be honest, sweet potato casserole is more of a dessert than a side dish, but on Thanksgiving we can get away with it, right?

Sweet potatoes seem to be a polarizing vegetable. Either you love them or hate them. I used to think that I didn’t like them, but soon after I got married I decided to give them another chance and they soon became one of my favorite vegetables.

This Sweet Potato Casserole is so good. It’s full of the sweet flavors of cinnamon, brown sugar and ooey-gooey marshmallows.

I love that this is a Slow Cooker recipe, becasue let’s be real, hosting Thanksgiving is a ton of work and anything that can be delegated to the Slow Cooker is a big time saver.

I know that you and your loved ones will enjoy this recipe as much as mine do. Happy cooking friends!
