Ingredients for Sweet Potato Casserole with Marshmallows

Here’s what you’ll need to make this delicious Sweet Potato Casserole with Marshmallows:

2 pounds fresh sweet potatoes – Choose sweet potatoes that are firm and smooth; they are the star of the dish, and fresh ones make a noticeable difference in flavor.
6 tablespoons granulated sugar – This will enhance the natural sweetness of the potatoes; adjust to your taste if you’re opting for a less sweet version.
4 tablespoons unsalted butter, melted – Butter adds richness; prefer unsalted so you can control the sodium.
1/4 cup milk – Use whole milk for creaminess; alternatives like almond or oat milk can work too.
2 large eggs – Eggs bind the ingredients together, creating a lovely, fluffy texture.
1/2 teaspoon vanilla extract – Vanilla brings out the sweetness and adds a lovely aroma.
1/2 teaspoon salt – It enhances all the other flavors in this dish.
3 cups mini marshmallows – These create the dreamy, fluffy topping and a delightful sweet finish.

How to Make Sweet Potato Casserole with Marshmallows

Follow these simple steps to prepare this delicious Sweet Potato Casserole with Marshmallows:

Step 1: Bake the Sweet Potatoes
Preheat your oven to 400°F (200°C) and line a sheet pan with foil for easy cleanup. Place the sweet potatoes on the pan, poke them with a fork to release any steam, and bake for 40-50 minutes until they’re tender and can be easily pierced with a fork. The aroma of roasting sweet potatoes is sure to start making your mouth water.

Step 2: Cool and Prepare the Mixture
Once baked, lower the oven temperature to 350°F (175°C) and let the sweet potatoes cool for about 20 minutes. Meanwhile, in a large mixing bowl, whisk together the granulated sugar, melted butter, milk, vanilla, and salt until well combined.

Step 3: Mash It Up
Peel the sweet potatoes—be careful, they’ll be hot! Add them to the bowl and mash everything together until smooth. Stir in the eggs, mixing until combined. This mixture should look like a velvety sweet potato dream, perfect for about 6 people (or just one very happy food lover).

Step 4: Bake the Casserole
Spread the sweet potato mixture evenly into a 20-ounce baking dish. Bake for 20 minutes, allowing it to set and develop a bit of a crust on top before we hit it with the real star of the show.

Step 5: Top with Marshmallows
Take the dish out and layer the mini marshmallows generously over the top. Pop it back in the oven and bake for an additional 5-10 minutes, or until the marshmallows are puffed and golden brown. This is where the magic happens; you’ll gasp as your kitchen fills with the sweet, toasty aroma.

Step 6: Serve and Enjoy
Let the casserole cool for a few minutes before serving. Scooping out this gloriously fluffy, sweet dish will send smiles around the table as you say, “I made this!” Serve it warm and watch it disappear in a matter of minutes. It pairs beautifully with roasted turkey or simply enjoyed on its own as a comforting dessert.

This sweet potato casserole with marshmallows blends the wholesome elegance of sweet potatoes with the playful mischief of toasted marshmallows. Take a moment to relish each bite—because life is too short not to enjoy every sweet mouthful!
