My kids used to scrape the marshmallows off when they were younger, so I tried making a healthier sweet potato casserole without marshmallows. After many complaints to the management, the marshmallows are back!
A word to the wise — Don’t mess with sacred holiday side dishes!
How to Make Sweet Potato Casserole with Marshmallows
Next, carefully remove the sweet potatoes from their jackets (they’re hot), and place them into a large bowl or casserole dish. I usually just mix everything in the casserole dish.
Mash the sweet potatoes with some butter, maple syrup, brown sugar and cinnamon. Then, smooth the potatoes evenly in the casserole dish.
Sprinkle enough mini marshmallows over the potatoes so that they are completely covered. And, pop the casserole under the broiler for about 5 minutes or until the marshmallows are golden brown.
The marshmallows are crispy on top, soft and melty on the bottom, and the sweet potatoes are smooth and creamy underneath. Good stuff!
How to Prepare Sweet Potato Casserole Ahead of Time
If you want to make the casserole a few days in advance, mash the potatoes, cover the baking dish in plastic wrap, and refrigerate until you’re ready to serve. Then, uncover and reheat the casserole in the microwave, your oven, or try your air fryer oven if you have one.
You may have to add a little more maple syrup or butter if the casserole seems dry. When the sweet potatoes are heated through, top with marshmallows, and broil.
