Sweet Potato Casserole with Marshmallows and Pecans

Sweet Potato Casserole with Marshmallows and Pecans blends mashed sweet potatoes with cinnamon, ginger, maple syrup, and egg, folded with mini marshmallows, then topped with more marshmallows, chopped pecans, and brown sugar before baking. The result is a warm, sweet, and slightly spiced casserole with a soft interior and a crunchy topping.

Description

This casserole begins with boiled sweet potatoes that are peeled, cubed, and softened, then mashed smoothly. Mixing in egg, maple syrup, cinnamon, and ginger, the base balances natural sweetness and mild spice. Incorporating mini marshmallows into the mash adds a subtle sweetness and melt-in-the-mouth texture inside.

Topped with additional marshmallows, chopped pecans, and brown sugar, the casserole develops a golden, crunchy layer during baking. The pecans provide texture contrast, while the brown sugar caramelizes over the marshmallows, enhancing richness and sweetness. Baking at 350°F yields a warm, comforting dish with a creamy interior and slightly crisp topping.

This dish traditionally serves as a side for holiday meals but can also be enjoyed as a sweet side or dessert. It pairs well with savory proteins or festive dinners.

The recipe allows roasting the sweet potatoes whole as an alternative to boiling. Pecans can be toasted beforehand for extra crunch and flavor. Leftovers store well in an airtight container for up to five days and can be reheated in the oven at a low temperature to retain texture. This casserole also freezes well for up to three months, with thawing recommended overnight prior to reheating.
