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 vibrant, firm sweet potatoes for the sweetest flavor and creamy texture. The fresher, the better!

6 tablespoons granulated sugar – This adds a delightful sweetness to contrast the natural earthiness of the sweet potatoes. Feel free to use less if you prefer a less sweet casserole.

4 tablespoons (2 ounces) unsalted butter, melted – Adds richness and depth to the flavor of your casserole. Unsalted ensures you can control the saltiness.

1/4 cup milk – Choose whole milk for a creamier texture, but low-fat milk can work if you’re looking to cut calories.

2 large eggs – These help bind the mixture together, giving it a fluffier, more cohesive structure.

1/2 teaspoon vanilla extract – Just a touch adds complexity and enhances the sweetness of the dish.

1/2 teaspoon salt – Balances sweetness and enhances the overall flavor profile of the casserole.

3 cups mini marshmallows – The crowning glory of this dish! They create a gooey, sweet topping that toasts beautifully.

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). Line a sheet pan with foil to catch any sweet potato drips that may occur (trust me; it’s a sweet mess!). Prick each sweet potato with a fork so they don’t explode while baking. Bake for 40-50 minutes, or until they are fork-tender.

Step 2: Let Cool and Mix Ingredients
Once the sweet potatoes are baked, lower the oven temperature to 350°F (175°C) and let them cool for at least 20 minutes. In a medium-sized mixing bowl, whisk together the sugar, melted butter, milk, vanilla, and salt until combined.

Step 3: Prepare the Sweet Potatoes
Peel the sweet potatoes, tossing the skins aside like an overzealous chef. Add the sweet potato flesh to the mixing bowl. With a fork or a potato masher, stir and mash everything together until you have a smooth blend. Then, add the eggs and give it another good mix.

Step 4: Bake the Casserole
Spread the sweet potato mixture evenly into a small 20-ounce baking dish. Bake for 20 minutes, allowing the flavors to meld together beautifully. Your kitchen will smell like a dream!

Step 5: Add the Marshmallows and Toast
Take the dish out of the oven after 20 minutes. Scatter the mini marshmallows on top, creating a whimsical layer that screams, “Look at me!” Return the dish to the oven and bake for another 5-10 minutes, until the marshmallows are gloriously golden brown and puffed up.

Step 6: Serve and Enjoy
Once your Sweet Potato Casserole with Marshmallows is out of the oven, let it sit for a minute as you admire your masterpiece. Serve it warm, and watch as everyone at the table dives in, eager for a taste of that sweet, sweet nostalgia. Nothing says, “I care” like a homemade casserole.
