Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

6 medium to large-size sweet potatoes
2 large eggs
1/2 stick unsalted butter
1/3 cup packed light brown sugar
1 teaspoon ground cinnamon
coarse salt and fresh cracked pepper to taste
1/3 cup all-purpose flour
1/3 cup packed light brown sugar
3/4 cup roughly chopped pecans
1/2 stick unsalted butter
1 cup mini marshmallows

Directions

Preheat the oven to 375°.

Place the sweet potatoes on a lined baking sheet and bake for 60 to 70 minutes, or until they are very tender.

Remove the potatoes from the oven, let them cool slightly, then peel off and discard the skins. Transfer the soft potato flesh to a large bowl.

Add the eggs, butter, brown sugar, cinnamon, salt, and pepper. Mash everything together using a hand masher or an electric mixer until smooth and creamy.

Spread the mashed sweet potato mixture evenly into a greased 13×9-inch casserole dish and set aside.

In another bowl, combine the flour, brown sugar, pecans, and butter. Mix until the butter is broken down into small pieces, about the size of rice.

Fold in the mini marshmallows, then sprinkle the mixture evenly over the sweet potatoes, covering the surface completely.

Bake for 25 to 30 minutes, or until the topping is golden and the marshmallows are lightly browned. Serve warm.

Servings and timing

This recipe yields about 10 servings and takes approximately 1 hour and 40 minutes from start to finish, including baking time.

Variations

For a less sweet version, reduce the amount of sugar or skip the marshmallows and focus on the pecan topping. You can add a splash of vanilla extract or a pinch of nutmeg for extra warmth. If you prefer a smoother topping, omit the pecans and create a simple crumble. For a dairy-free option, substitute the butter with a plant-based alternative.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, cover the casserole with foil and warm it in the oven at a low temperature until heated through. Individual portions can also be reheated in the microwave, though the topping may lose some crispness.
