Ingredients:

4 large sweet potatoes, peeled and chopped into large chunks (around 9 cups worth)
½ cup unsalted butter, melted
1 cup brown sugar
½ teaspoon salt
½ teaspoon cinnamon
1 teaspoon vanilla extract
¼ teaspoon nutmeg
4 tablespoons unsalted butter, melted
⅓ cup brown sugar
2 tablespoons all-purpose flour
½ teaspoon salt
1 ¼ cups finely chopped pecan pieces
10 oz mini marshmallows

Preparing the Sweet Potato Base

The foundation of a truly spectacular Sweet Potato Casserole with Marshmallows lies in perfectly cooked sweet potatoes. To begin, preheat your oven to 400°F (200°C). This initial high heat helps to soften the sweet potatoes quickly. Place your peeled and chopped sweet potato chunks in a large pot and cover them generously with cold water. Add a pinch of salt to the water; this not only seasons the potatoes as they cook but also helps them cook more evenly. Bring the water to a rolling boil over high heat, then reduce the heat to medium and let them simmer for about 15-20 minutes, or until they are fork-tender. You should be able to easily pierce them with a fork or a knife. Once tender, carefully drain the sweet potatoes in a colander, allowing any excess water to escape. This step is crucial to prevent a watery casserole.

Mashing and Flavoring the Sweet Potatoes

Now it’s time to transform those cooked sweet potatoes into a smooth, flavorful base. Return the drained sweet potatoes to the warm pot you used for boiling. This residual heat will help evaporate any remaining moisture. Add the ½ cup of melted unsalted butter to the pot. This butter will lend richness and a delightful mouthfeel to the casserole. Next, incorporate the 1 cup of brown sugar. The brown sugar not only adds sweetness but also a lovely caramel undertone that pairs beautifully with the sweet potatoes. Sprinkle in the ½ teaspoon of salt to balance the sweetness and enhance all the flavors. For warmth and spice, add the ½ teaspoon of cinnamon and the ¼ teaspoon of nutmeg. These classic fall spices are essential for that comforting, cozy flavor profile. Finally, stir in the 1 teaspoon of vanilla extract for its aromatic sweetness. Using a potato masher or an electric mixer on low speed, mash the sweet potatoes until they are mostly smooth. Don’t over-mash them into a paste; a few small lumps add a pleasing texture. Ensure all the ingredients are thoroughly combined and that the mixture is well-seasoned. Taste it at this stage and adjust any seasonings if necessary.

Assembling the Pecan Streusel Topping

While the sweet potato mixture is still warm, let’s get started on the irresistible pecan streusel topping. In a medium bowl, combine the remaining 4 tablespoons of melted unsalted butter with the ⅓ cup of brown sugar. This forms the sticky base of our crumble. Next, whisk in the 2 tablespoons of all-purpose flour. The flour acts as a binder, helping to create a cohesive and satisfyingly crumbly topping. Add the remaining ½ teaspoon of salt to this mixture to ensure a balanced flavor in the topping as well. Now, for the star of the show in the topping: the 1 ¼ cups of finely chopped pecan pieces. These crunchy, nutty morsels will provide a wonderful textural contrast to the creamy sweet potato base. Add the chopped pecans to the butter, sugar, flour, and salt mixture. Using a fork or your fingertips, mix everything together until it resembles coarse crumbs. You want to ensure the pecans are evenly coated with the butter and sugar mixture, creating clusters of deliciousness.

Layering and Baking the Casserole

Now that all the components are ready, it’s time to bring them together and bake this delightful Sweet Potato Casserole with Marshmallows. Grease a 9×13 inch baking dish with butter or cooking spray to prevent sticking. Spoon the prepared sweet potato mixture evenly into the prepared baking dish, spreading it out into a smooth layer. Gently pat the top smooth with the back of a spoon or a spatula. The next step is where the magic truly happens. Evenly sprinkle the prepared pecan streusel topping over the entire surface of the sweet potato layer. Make sure to cover as much of the sweet potato as possible with the crumble to achieve that perfect crunchy topping.

The Marshmallow Finish and Final Bake

The grand finale for our Sweet Potato Casserole with Marshmallows involves the beloved marshmallows. Once the streusel topping is in place, carefully arrange the 10 oz of mini marshmallows over the top. You can place them in a single layer, or if you prefer a more decadent, gooey topping, feel free to pile them on generously. Ensure they are distributed evenly across the streusel. Place the assembled casserole into the preheated oven, which should now be at 350°F (175°C). This slightly lower temperature is perfect for melting the marshmallows and browning the topping without burning them. Bake for 20-25 minutes, or until the marshmallows are puffed up, golden brown, and irresistibly gooey, and the edges of the casserole are bubbling. Keep a close eye on it during the last 10 minutes of baking, as marshmallows can go from perfectly toasted to burnt very quickly. If the marshmallows are browning too fast but the casserole isn’t heated through, you can loosely tent the dish with aluminum foil. Once out of the oven, let the Sweet Potato Casserole with Marshmallows rest for about 10 minutes before serving. This allows the flavors to meld and the casserole to set slightly, making it easier to serve.
