Preheat your oven to 375°F (190°C). Place your cubed sweet potatoes in a large pot, cover with water, and bring to a boil. Cook until tender—about 12–15 minutes. Drain well and return them to the pot. Using a hand mixer or masher, blend the potatoes until smooth. Add in your softened butter, maple syrup, milk, vanilla, cinnamon, nutmeg, and salt. Mix until it’s velvety and well-combined. Spread this creamy sweet potato mixture evenly into a greased baking dish. Top generously with mini marshmallows. Bake for 20–25 minutes, or until the marshmallows are golden and toasted to perfection.
Getting Your Timings Just Right
Don’t worry—you won’t be stuck in the kitchen all day with this one. I usually spend about 25 minutes prepping everything (peeling, chopping, boiling), and then the casserole bakes for another 25 minutes. In under an hour, you’ll have a warm, inviting holiday side dish ready to share. Perfect for a slow, cozy weekend or a festive evening with loved ones. If you’re looking for more sweet potato inspiration, try these easy roasted sweet potatoes—they’re just as simple and satisfying.
Marshmallow Sweet Potato Casserole
Ingredients
- 5 pounds sweet potatoes peeled and cut into 2-inch chunks
- 8 tablespoons unsalted butter melted and slightly cooled
- 1/2 cup granulated sugar
- 2 large eggs lightly beaten
- 1 tsp vanilla extract
- 1/2 tsp kosher salt
- 1/4 cup whole milk
- 1/4 cup orange juice
- 1 10.5-ounce bag miniature marshmallows
Method
- Place the sweet potato chunks in a large pot and cover with cold water by 1 inch. Bring to a boil over high heat, then reduce heat to medium and simmer for 20-25 minutes until the potatoes are very tender when pierced with a fork.
- Drain the sweet potatoes thoroughly in a colander, then transfer them to a large mixing bowl. Mash with a potato masher or beat with an electric mixer on medium speed until completely smooth with no lumps remaining.
- Preheat your oven to 350°F and grease a 9×13-inch baking dish with butter or nonstick cooking spray. Let the mashed sweet potatoes cool for 5 minutes, then stir in the melted butter, granulated sugar, beaten eggs, vanilla extract, salt, whole milk, and orange juice until fully combined.
- Spread the sweet potato mixture evenly into the prepared baking dish using a rubber spatula. Bake uncovered for 30-35 minutes until the edges are lightly bubbly and the center is set.
- Remove the casserole from the oven and evenly scatter the miniature marshmallows across the entire surface. Return to the oven for 5-7 minutes until the marshmallows are puffed, golden brown, and toasted.

Thoughtful Tips for Special Diets
I love making recipes work for everyone around the table. If you’re sugar-conscious or exploring diabetic-friendly options, here’s how we can tweak this casserole together. Instead of maple syrup, try a natural sugar alternative like stevia or xylitol—they blend beautifully with the sweet potatoes’ natural sweetness. You could also reduce the marshmallows or look for a sugar-free version. Another tip? Keep portion sizes modest and balance your plate with protein and veggies. It’s all about enjoying real food in a way that feels good for you.
My Favorite Tweaks for Even More Flavor
Over the years, I’ve learned a few tricks to make this casserole even more special:
- For a richer flavor, swap the vanilla with a dash of orange zest—it brightens everything up!
- If you’re avoiding dairy, coconut milk works wonderfully in place of regular milk.
- To avoid a soupy texture, make sure your sweet potatoes are well-drained before mashing.
- Leftovers reheat beautifully in the oven at 300°F for 15 minutes—cover lightly with foil to prevent over-browning.

How to Serve This Heartwarming Dish
I love serving this casserole straight from the oven, with the marshmallows still puffed and golden. It pairs beautifully with roasted turkey, glazed ham, or even a simple weeknight roast chicken.

Avoid These Common Casserole Mistakes
Even the coziest recipes can have pitfalls—here’s how to avoid them:
- Overboiling the sweet potatoes: This can make them watery. Cook until just fork-tender.
- Adding marshmallows too early: If they go on before the last 10–15 minutes, they can melt too much and become chewy instead of toasty.
- Not tasting before baking: Adjust sweetness and spice to your liking while the mixture is still in the bowl.

Storing Your Leftovers for Later Coziness
We rarely have leftovers, but when we do, I cherish them! This casserole keeps well in an airtight container in the fridge for up to 4 days. Reheat gently in the oven to restore that toasted topping. It also freezes well (without the marshmallow topping) for up to 2 months. Just add fresh marshmallows when you’re ready to bake again.

Frequently Asked Questions
When to put marshmallows on sweet potato casserole?
I always add marshmallows during the last 10–15 minutes of baking. This gives them enough time to get golden and toasty without burning or melting completely into the dish. If you’re using a broiler at the end, watch them closely—they can go from perfect to overdone in seconds!
What does Texas Roadhouse put on their loaded sweet potatoes?
While their exact recipe is a secret, Texas Roadhouse is known for loading their sweet potatoes with butter, cinnamon sugar, and marshmallow topping. For a homemade version that’s just as indulgent, try adding a pat of butter and a sprinkle of brown sugar before the marshmallows.
