This one’s the real deal! Butter, brown sugar and fresh mashed sweet potatoes all topped with melted marshmallows… basically THE BEST sweet potato casserole with marshmallows.
My Mom had a big sweet tooth. She would stash Little Debbie’s and chocolate bars around the house trying to ensure she’d have something sweet when the cravings kicked in. She was also very southern in her style of cooking, so you could expect a dash (or a lot) of sugar to go into most dishes including her macaroni and cheese. And it all tasted so good.
So it’s no surprise that her famous best sweet potato casserole with marshmallows is the real deal. Yup, I’m talking brown sugar AND real butter AND marshmallows, friends.
The Best Sweet Potato Casserole with Marshmallows
I haven’t shared this recipe on Running in a Skirt because I worried that it doesn’t exactly fit into the healthy mold I try to create here. BUT I believe that you should eat and enjoy foods like this in moderation, especially when it is such a family favorite.
Making this best sweet potato casserole with marshmallows recipe and keeping it at the family table during the holidays helps keep my Mom’s memory alive. I believe in traditional family recipes and I believe in THIS recipe. I know it if you try it you will also make it a family favorite.
Beyond being a family favorite, this really is the best sweet potato casserole with marshmallows recipe. It uses fresh sweet potatoes, hand mashed to perfection and big doses of cinnamon and nutmeg.
My Mom’s big secret is she made her recipe and THEN added even more brown sugar until it was absolutely sinful. If you really want to channel her sweet tooth, I suggest doing the same thing… but just for Thanksgiving. AND maybe Christmas too…. I promise not to tell.
The sweet potato mixture bakes to perfection and the marshmallows turn golden brown on top.
This one is truly from my heart guys, I hope you enjoy it as much as I do!
