These Crockpot Sweet Potatoes with Marshmallows are the ultimate comfort side dish. They combine the warm, natural sweetness of slow-cooked sweet potatoes with a buttery brown sugar glaze and pillowy marshmallows melted just enough to make each bite heavenly. Whether you’re prepping for a holiday feast or just need an easy weeknight side, this dish delivers every single time.

What makes this recipe a keeper? The simplicity. Toss everything into the crockpot, walk away, and let the magic happen. In just a few hours, you’ll have soft, caramelized sweet potatoes infused with rich fall spices and topped with the nostalgic charm of gooey, golden marshmallows.

What Kind of Sweet Potatoes Should I Use?

Go for firm, orange-fleshed sweet potatoes, often labeled as “yams” in stores. These have a naturally sweet flavor and become creamy when slow-cooked. Avoid white or purple varieties for this dish—they don’t have the same texture or sweetness needed to balance the brown sugar and marshmallows.

Ingredients for the Crockpot Sweet Potatoes with Marshmallows

Sweet Potatoes – The star of the show. They absorb all the buttery, sweet flavor while turning perfectly tender.

Brown Sugar – Brings that deep molasses sweetness that caramelizes beautifully during cooking.

Butter – Rich and velvety, butter helps the glaze coat every cube of sweet potato.

Cinnamon – Adds a warm, spiced kick that enhances the natural sweetness.

Salt – A pinch helps balance the sweet elements and deepens flavor.

Vanilla Extract – Introduces a subtle warmth and complexity.

Mini Marshmallows – Melted on top just before serving, they add a fun, gooey layer kids and adults both love.

How To Make the Crockpot Sweet Potatoes with Marshmallows

Step 1: Peel and Chop the Sweet Potatoes

Peel 3 pounds of sweet potatoes and cut them into uniform 1-inch cubes for even cooking.

Step 2: Make the Sweet Glaze

In a small saucepan or microwave-safe bowl, melt 1/2 cup unsalted butter and stir in 1/2 cup brown sugar, 1 tsp cinnamon, 1/4 tsp salt, and 1 tsp vanilla extract. Mix until smooth.

Step 3: Load the Crockpot

Add the chopped sweet potatoes into the crockpot and pour the glaze evenly over them. Stir gently to coat all the pieces.

Step 4: Cook Low and Slow

Cover and cook on LOW for 5-6 hours or on HIGH for 3 hours, until the sweet potatoes are fork-tender.

Step 5: Add Marshmallows

Sprinkle 2 cups of mini marshmallows on top, cover for 5-10 minutes more until they’re soft and slightly melted. Serve warm and melty.
