If you want a foolproof holiday side dish that practically cooks itself, Crockpot Sweet Potatoes with Marshmallows is exactly what you need. This recipe gives you all the warm, cozy flavors of classic candied sweet potatoes but with the hands-off convenience only a slow cooker provides.

Whether it’s Thanksgiving, Christmas, or a simple weeknight dinner where you want something comforting and sweet, this dish never fails. Soft, buttery sweet potatoes slow-cook to perfection and are topped with gooey, golden marshmallows that melt into a dreamy dessert-like topping.

Not only does the crockpot save oven space (crucial for holidays), but it delivers perfectly tender potatoes and allows the flavors to deepen slowly. Let this dish simmer away while you handle the rest of your menu — or enjoy it as a set-it-and-go side that impresses with zero effort.

Why This Recipe Works

1. Slow Cooking Unlocks Maximum Flavor

As the sweet potatoes gently cook, the butter, cinnamon, and vanilla soak deep into every bite.

2. Marshmallows = The Iconic Finish

They melt into a caramel-like layer that transforms simple sweet potatoes into a sweet, dreamy topping.

3. Saves Oven Space

Crockpots shine during busy cooking days — freeing your oven for turkey, stuffing, or casseroles.

4. Works for Meal Prep

Great for holidays but also perfect for weekly prep.

5. Only a Few Ingredients

Simple staples = big flavor.
