Ingredients

  • 4 lbs sweet potatoes, peeled and cut into 1-inch cubes
  • 1/2 cup unsalted butter, melted, plus extra for greasing
  • 1/2 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 1/2 cup whole milk (or heavy cream for a richer casserole)
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 5 cups mini marshmallows

Instructions

  • Step 1: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
  • Step 2: Place the cubed sweet potatoes in a large pot and cover with cold water. Bring to a boil over high heat, then reduce heat to medium and simmer until fork-tender, about 15-20 minutes.
  • Step 3: Drain the sweet potatoes thoroughly. Return them to the pot and mash them until smooth.
  • Step 4: Add the melted butter, brown sugar, granulated sugar, milk, eggs, vanilla extract, cinnamon, nutmeg, and salt to the mashed sweet potatoes. Mix well until everything is fully combined and smooth.
  • Step 5: Spread the sweet potato mixture evenly into the prepared baking dish.
  • Step 6: Bake for 25-30 minutes, or until the edges are lightly bubbling.
  • Step 7: Remove the casserole from the oven. Evenly sprinkle the mini marshmallows over the top.
  • Step 8: Return the casserole to the oven and bake for another 5-10 minutes, or until the marshmallows are golden brown and puffed. Keep a close eye on them, as marshmallows can burn quickly.
  • Step 9: Let the casserole stand for 5-10 minutes before serving to allow it to set slightly. Serve warm and enjoy!

Recipe Variations

While the classic Sweet Potato Casserole with Marshmallows is undeniably delicious, don't hesitate to personalize your dish! For a crunchy element, consider adding a pecan streusel topping instead of or in addition to marshmallows. Simply combine 1/2 cup chopped pecans, 1/4 cup brown sugar, 2 tablespoons melted butter, and 1/4 cup flour; sprinkle over the sweet potato mixture before baking. You could also swap out whole milk for cream cheese in the potato mixture for an even richer, tangier base, or add a pinch of ginger for an extra warm spice note.

Pro Tips for Success

Achieving the perfect sweet potato casserole is all about technique. Firstly, ensure your sweet potatoes are thoroughly drained after boiling; excess water can make your casserole runny. Mashing them while hot helps achieve a smoother consistency. When adding the marshmallows, monitor them closely during the final bake. They can go from perfectly golden to burnt in a matter of seconds! If you notice them browning too quickly, you can cover the casserole loosely with foil. Also, don't be afraid to taste and adjust the seasonings before baking; everyone's preference for sweetness and spice is different.

Storage and Reheating Instructions

To store leftover sweet potato casserole, allow it to cool completely, then cover tightly with plastic wrap or aluminum foil and refrigerate for up to 3-4 days. For reheating, you can warm individual servings in the microwave or reheat the entire casserole in an oven preheated to 325°F (160°C) until heated through, typically 20-30 minutes. If the marshmallows have deflated, you can add a fresh layer for the last few minutes of reheating for that fresh-baked look and texture.

You can freeze the sweet potato base without the marshmallow topping for up to 3 months. Assemble the casserole in a freezer-safe dish, cover tightly, and freeze. Thaw overnight in the refrigerator before baking. Add fresh marshmallows just before the final baking step.



Is sweet potato casserole a dessert or a side dish?

Sweet potato casserole with marshmallows uniquely blurs the line between a side dish and a dessert.
