How To Make the Crockpot Sweet Potatoes with Marshmallows

Step 1: Prep the Sweet Potatoes

Peel and chop the sweet potatoes into 1-inch chunks. Uniform size ensures even cooking in the crockpot.

Step 2: Make the Sweet Glaze

In a mixing bowl, whisk together brown sugar, melted butter, cinnamon, and a pinch of salt until well combined.

Step 3: Load the Crockpot

Place the chopped sweet potatoes into the slow cooker. Pour the glaze over them and stir gently to coat every piece.

Step 4: Cook Low and Slow

Cover and cook on LOW for 6 hours or on HIGH for 3-4 hours, until potatoes are tender when pierced with a fork.

Step 5: Add the Marshmallows

Once cooked, top the sweet potatoes with mini marshmallows. Cover again for 5-10 minutes, just until they start to melt and turn gooey.

Step 6: Serve Warm

Scoop onto plates and serve warm. The sticky glaze and melted marshmallows make it an irresistible side.

Serving and Storing Crockpot Sweet Potatoes with Marshmallows

This dish is best served fresh and warm right out of the slow cooker. It pairs beautifully with roasted turkey, glazed ham, or any hearty fall-inspired main course.

To store leftovers, let the sweet potatoes cool completely before transferring them to an airtight container. Refrigerate for up to 4 days. To reheat, simply microwave individual portions or warm in a covered dish in the oven at 300°F until heated through. If the marshmallows have dissolved during storage, feel free to add a few fresh ones before reheating.

Freezing is not recommended as the texture of the potatoes and marshmallows may change after thawing.

Frequently Asked Questions

Can I make this ahead of time?

Yes! You can cook the sweet potatoes and refrigerate them without the marshmallows. Just add marshmallows and reheat before serving.

Can I use canned sweet potatoes?

It’s best to use fresh sweet potatoes. Canned ones may become too mushy after slow cooking.

Can I add pecans or other toppings?

Absolutely! Toasted pecans, chopped walnuts, or a drizzle of maple syrup add great texture and flavor.

What size crockpot should I use?

A 4 to 6-quart crockpot works well. If doubling the recipe, go for an 8-quart.

How do I keep the marshmallows from melting too much?

Add them at the end and keep the lid on for just 5-10 minutes—they should soften but not disintegrate.

Can I make this dairy-free?

Yes, use a plant-based butter substitute and double-check your marshmallows for dairy-free labeling.
