Sweet Potato Casserole with Marshmallows

Whenever we visited my Grandma for a holiday, she would spend so much time in the kitchen cooking from scratch. As a girl, I loved nothing more than being in the kitchen with her, helping to make all the homemade treats.

I fondly remember making this sweet potato casserole recipe with her. When I was very little, I would help with simple things like adding all the ingredients into the dish. Now, I do the same with my children. They love helping me make this classic casserole.

One of the things I love the most about my Grandma’s easy sweet potato casserole recipe with marshmallows is all the fresh and delicious ingredients. Whenever she could, she would try to get her sweet potatoes fresh from a market so she knew they were the best of the best. When it came to the quality of food, she never compromised.

The thing that makes this one of my top rated casseroles is the topping. It wouldn’t be an amazing sweet potato casserole without the baked marshmallow topping.

Some people in my family like to stick to the original white marshmallows on top of their sweet potato casserole. If you want to make your casserole slightly less traditional, my Grandma would sprinkle the top of her sweet potato casserole recipe with nuts like pecans.

How to Make Sweet Potato Casserole

Making this sweet potato casserole with marshmallows couldn’t be easier. With few ingredients and only a handful of steps to follow you’ll be tucking into sweet potato goodness before you know it.

Out of all the baked dishes that my Grandma makes, this has to be my all-time favorite. Good homemade sweet potato casserole begins with the sweet potatoes of course. You need to make sure that they’re cooked just right. Skin them, then cut into one inch chunks. Boil in a pan of water until soft.

To create your syrup, boil water, brown sugar and butter until reduced. It will be the consistency of maple syrup.

Once the sweet potatoes are fully cooked, layer them in the bottom of a casserole dish. Pour the syrup over them and top with mini marshmallows.

Bake at 350* for about 30 minutes. You’ll want to watch closely to make sure the marshmallows don’t burn. You just want them toasted, like in s’mores. And they can burn fast at the end, so be diligent.

The only downside to this recipe is that you’ll be hard pushed to keep any leftovers as you’ll more than likely be going back for second helpings. 🙂
