Why You’ll Love This Crockpot Sweet Potatoes with Marshmallows
This is not your average sweet potato side dish. First, the crockpot ensures perfectly cooked, fork-tender sweet potatoes every time without needing to babysit the oven. Then comes the hint of brown sugar and cinnamon, enhancing the natural sugars of the potatoes beautifully. And let’s not forget the crown of mini marshmallows that adds that irresistible melt and toast at the end. It’s simple, comforting, and everyone from kids to adults devours it.
Can I Use Canned Sweet Potatoes Instead of Fresh?
You technically can, but fresh sweet potatoes are definitely the way to go. They hold up better in the slow cooker and develop a rich, deep flavor that canned ones just can’t match. Plus, using fresh allows you to control the texture and sweetness, so it doesn’t get overly mushy or sugary.
Ingredients for the Crockpot Sweet Potatoes with Marshmallows
Sweet, soft, and lightly spiced, this dish shines with just a few key ingredients. The flavors play off each other beautifully, and each one has a purpose in creating that signature taste.
- Sweet Potatoes: The heart of this dish. Choose firm, medium-sized ones for the best texture.
- Brown Sugar: Adds a caramel note and enhances the natural sweetness.
- Butter: Richness and flavor are boosted by a few tablespoons of butter.
- Ground Cinnamon: Warms up the dish with cozy spice.
- Salt: Just a pinch helps balance out the sweetness.
- Mini Marshmallows: The final gooey topping that gets melty and golden right before serving.

How To Make the Crockpot Sweet Potatoes with Marshmallows
Step 1: Peel and Slice the Sweet Potatoes
Start by peeling your sweet potatoes and cutting them into 1/2-inch thick rounds or chunks. Try to keep them uniform for even cooking.
Step 2: Layer in the Crockpot
Place the sliced sweet potatoes into the crockpot. Dot them with pieces of butter, sprinkle the brown sugar and cinnamon evenly over the top, and add a pinch of salt.
Step 3: Cook Low and Slow
Cover and cook on low for about 5 to 6 hours, or until the sweet potatoes are tender and easy to pierce with a fork. Stir gently halfway through to coat the potatoes with that buttery sweet mixture.
Step 4: Add the Marshmallows
Once the potatoes are soft and flavorful, top them with mini marshmallows. Cover again and let cook for another 10 to 15 minutes, just until the marshmallows are melted and slightly golden.
Step 5: Serve Warm
Give everything a light stir or serve as is for a more layered look. Either way, serve warm and enjoy the blend of textures and flavors.
How to Serve and Store Crockpot Sweet Potatoes with Marshmallows
This recipe easily serves 6 to 8 people, making it perfect for holidays or when you’re entertaining guests. Serve them right from the crockpot to keep them warm during dinner. They pair beautifully with roasted turkey, glazed ham, or even a simple herb-roasted chicken.
To store leftovers, transfer the sweet potatoes and marshmallows to an airtight container once they’ve cooled. Keep them in the refrigerator for up to 4 days. Reheat in the microwave or in the oven until warmed through and marshmallows are soft again. For longer storage, skip the marshmallows and freeze the sweet potatoes for up to 2 months.
