Easy Sweet Potato Casserole Recipe (with Marshmallows) ✨🍠

[recipe_dates]

From Campfire Cravings to Sweet Potato Casserole Bliss 📝🔥

The weather has finally turned chilly ❄️, and my kids have been begging us to drag out our little portable propane fire pit 🔥 so they can roast marshmallows in the backyard.

Watching them happily (and messily) crunch into burnt s’mores with frozen fingers 🧤 made me laugh—and also made me think. If they’re this obsessed with marshmallows, maybe I should surprise them with something even better: a holiday dish piled high with marshmallows from edge to edge.

That’s how this Sweet Potato Casserole Recipe with Marshmallows was born in my kitchen. 🍠 I grabbed my trusty Le Creuset baking dish 🥘, the one that always makes me feel a little fancier even on a Tuesday, and filled it with four simple ingredients that somehow feel like pure nostalgia — sweet potatoes, butter, brown sugar, and marshmallows.

Into the oven it went, and the transformation began. The sweet potatoes softened into silky, golden mash, the sugar melted into sticky caramel edges, and the marshmallows puffed into gooey clouds that smelled like campfire magic. ☁️✨

The kitchen smelled like brown sugar and childhood nostalgia — warm, buttery, and just a little toasty from the marshmallows crisping on top. Every time I catch that scent, it feels like the holidays have officially begun.

When I was little, my mom always made her sweet potato casserole from scratch with brown sugar and pecans. Now my kids insist it isn’t Thanksgiving without that golden, gooey topping. I guess every generation has its favorite version of this classic sweet potato casserole recipe. 🧡

💡 Fun fact: The very first sweet potato casserole recipe with marshmallows appeared in 1917, thanks to the Angelus Marshmallow Company’s brilliant idea to make holidays sweeter. 🍬 More than a hundred years later, it’s still a Thanksgiving tradition loved by families everywhere.

When I pulled it out of the oven, the marshmallows were perfectly bronzed and crackly on top, like a toasted campfire dream. The kids squealed, my partner claimed a corner piece before dinner even started, and I realized this easy sweet potato casserole recipe isn’t just comfort food. It’s joy in a baking dish.

The mix of caramelized sweet potatoes, melted butter, and that gooey marshmallow crust makes every bite taste like dessert pretending to be dinner. 🍮 And really, who could argue with that?

Over the years, our family has joined the great sweet potato casserole recipe debate: marshmallows or pecans? 🥜 We’re firmly on Team Marshmallow, but I’ll admit there’s no wrong answer when something this cozy comes out of the oven.

By the time dinner was ready, the casserole sat proudly beside the turkey, its marshmallows perfectly puffed and glowing like holiday lights. Someone always sneaks the corner piece with extra topping (and yes, it’s usually me). 🍴

I hope this Sweet Potato Casserole Recipe with Marshmallows brings as much warmth, sweetness, and holiday cheer to your family as it does to mine! ✨
