Why Sweet Potato Casserole with Marshmallows Is So Popular
Sweet potatoes are naturally sweet and packed with nutrients like vitamin A and fiber. When mashed and combined with buttery goodness and a touch of cinnamon, they become irresistibly creamy. Adding marshmallows on top creates a beautiful caramelized layer that melts into a sweet, fluffy topping, adding texture and a fun twist to the dish.
This casserole is a staple on holiday menus, but it’s also simple enough for any weeknight dinner. If you love comfort food that pleases both kids and adults, this dish is an absolute must-try.

Sweet Potato Casserole Recipe
Step-by-Step Sweet Potato Casserole Recipe
1. Prepare the Sweet Potatoes
Start by peeling and cutting your sweet potatoes into chunks. Boil them in water for about 15-20 minutes, or until fork-tender. Drain and mash them until smooth.
2. Mix the Sweet Potato Base
In a large bowl, combine the mashed sweet potatoes with sugar, beaten eggs, melted butter, milk, vanilla extract, cinnamon, and salt. Stir everything together until smooth and creamy.
3. Assemble the Casserole
Spread the sweet potato mixture evenly in a greased 9×13-inch baking dish. This will be the base of your casserole.
4. Add the Marshmallow Topping
Sprinkle the mini marshmallows evenly over the top of the sweet potato layer. Don’t be shy—marshmallows are what make this dish so special!
5. Bake Until Golden
Bake your casserole at 350°F (175°C) for about 25-30 minutes. The marshmallows will puff up and turn golden brown, creating a sweet, crunchy crust on top.
6. Serve Warm and Enjoy!
Let the casserole cool for a few minutes before serving. The gooey marshmallow topping and creamy sweet potatoes are best enjoyed fresh and warm.
Tips for the Perfect Sweet Potato Casserole
Choose the right sweet potatoes: Look for firm, bright orange sweet potatoes for the best flavor and texture.
Avoid burning marshmallows: Keep an eye on the casserole in the last 5 minutes of baking to prevent the marshmallows from burning.
Make it ahead: You can assemble the casserole a day before and refrigerate it. Add the marshmallows just before baking.
Add nuts: For extra crunch, sprinkle chopped pecans or walnuts on top before adding the marshmallows.
