Soft, buttery, and sweet with gooey toasted marshmallows on top, these Marshmallow Crock Pot Sweet Potatoes are the ultimate comfort side dish. Whether it’s a holiday table or a cozy weeknight dinner, this recipe brings classic flavors with a fuss-free cooking method that keeps your oven free for the main event.

Slow-cooked to caramelized perfection, each sweet potato chunk soaks up brown sugar, butter, and cinnamon. Then just before serving, a blanket of mini marshmallows melts over the top, creating that dreamy toasted topping everyone loves. It’s warm, rich, and guaranteed to be devoured.

Preparation Phase & Tools to Use

To get the most out of your Marshmallow Crock Pot Sweet Potatoes, here’s what you’ll need:

Slow Cooker (Crock Pot) – The star of the show. A 6-quart model works best to evenly cook the sweet potatoes and let them absorb the buttery brown sugar blend slowly.
Vegetable Peeler – Peeling is essential for a smooth, soft bite. A good peeler saves you time and effort.
Sharp Chef’s Knife – For cutting the sweet potatoes into even chunks that cook uniformly.

Mixing Bowl – Handy to combine the sweet potatoes with your seasoning and melted butter before transferring to the Crock Pot.
Rubber Spatula or Wooden Spoon – For mixing and scraping every last bit of that delicious buttery-sugar mix.
Kitchen Torch (Optional) – If you want an extra toasted marshmallow top without broiling, a quick pass with a torch adds that golden finish.

Using the right tools not only speeds up prep time but ensures your sweet potatoes cook evenly and taste their best.

Ingredients for the Marshmallow Crock Pot Sweet Potatoes

Every ingredient in this recipe serves a cozy, flavorful purpose. Here’s what makes this dish shine:

Sweet Potatoes – The hero ingredient. Naturally sweet and creamy, they hold their shape while absorbing all the caramel flavors.

Brown Sugar – Adds rich molasses depth and melts into a glossy glaze.
Unsalted Butter – For that luxurious, silky texture and a hint of salty balance.
Cinnamon – Warms everything up with a spice that screams fall comfort.

Nutmeg (optional) – A little goes a long way. Adds an earthy note that pairs beautifully with sweet potatoes.
Salt – Just a pinch to highlight the sweet and savory balance.
Mini Marshmallows – The crowning glory. Sweet, melty, and slightly toasted for texture and indulgence.

How To Make the Marshmallow Crock Pot Sweet Potatoes

Step 1: Prep the Sweet Potatoes

Peel and chop your sweet potatoes into 1 to 1.5-inch cubes. Aim for uniform pieces so they cook evenly in the slow cooker.

Step 2: Combine Ingredients

In a large mixing bowl, toss the sweet potato cubes with melted butter, brown sugar, cinnamon, nutmeg (if using), and a pinch of salt. Coat everything thoroughly.

Step 3: Slow Cook to Perfection

Transfer the sweet potatoes to your Crock Pot and set it on LOW for 5-6 hours or HIGH for 2.5-3 hours. Stir once halfway through to ensure even cooking.

Step 4: Add the Marshmallows

Once the potatoes are fork-tender and caramelized, sprinkle mini marshmallows generously over the top. Cover and let them melt for about 5 minutes on WARM or LOW.

Step 5: Optional Toasted Finish

For an extra-toasty topping, use a kitchen torch or quickly broil the top in an oven-safe dish. Keep a close eye—those marshmallows brown fast!

Serving and Storing These Sweet Potatoes

Serve these Marshmallow Crock Pot Sweet Potatoes straight from the slow cooker for minimal cleanup and maximum warmth. They pair beautifully with roasted turkey, glazed ham, or even as a sweet contrast to spicy BBQ mains.

For storing, allow leftovers to cool completely, then transfer to an airtight container. They will keep in the refrigerator for up to 4 days. To reheat, warm in the microwave or gently in the oven. You can also add fresh marshmallows before reheating to refresh the topping.

Frequently Asked Questions

How do I keep the marshmallows from melting too much?

Add the marshmallows right before serving and set the Crock Pot to WARM. They’ll soften and melt slightly without turning into a gooey mess.

Can I make this recipe ahead of time?

Absolutely! You can prep and cook the sweet potatoes a day in advance, refrigerate them, and simply reheat with marshmallows on the day of serving.

Can I use canned sweet potatoes?

Fresh is best for texture, but in a pinch, canned (drained and rinsed) can work. Reduce the cooking time and keep an eye on texture to prevent mushiness.

How do I toast the marshmallows without an oven?

Use a kitchen torch for a quick, controlled char. It’s optional but adds a deliciously toasted flavor and golden finish.

Can I use large marshmallows instead?

Yes, but cut them in half. Mini marshmallows melt and distribute more evenly, so they’re generally preferred.

Are there dairy-free alternatives?

Swap the butter with a vegan substitute and ensure your marshmallows are gelatin-free to make it dairy- and vegan-friendly.
