2 pounds sweet potatoes (cleaned)
4 Tablespoons butter (softened or melted)
1/4 cup milk (or cream)
1 teaspoon ground cinnamon
1/4 cup brown sugar (packed)
2 Tablespoons maple syrup
1 large egg
1 teaspoon vanilla extract
1/2 teaspoon salt
1/2 cup butter (softened)
1/2 cup all-purpose flour
1/2 cup brown sugar (packed)
1 teaspoon ground cinnamon
3/4 cup pecans (chopped)
2–3 cups miniature marshmallows
Directions
-
Wash, peel, and cut the sweet potatoes into 1-inch chunks. Place them in a large pot and cover with water. Bring the pot to a boil over high heat, then reduce the heat to medium-high and simmer until the sweet potatoes are fork-tender.
-
Drain the sweet potatoes using a colander and return them to the pot. Add the butter, milk, cinnamon, brown sugar, maple syrup, egg, vanilla extract, and salt. Mash with a potato masher or beat with an electric mixer until smooth and well combined.
-
Preheat the oven to 375°F (190°C). Grease a 3-quart baking dish with non-stick cooking spray.
-
Spread the mashed sweet potato mixture evenly in the prepared baking dish.
-
In a medium bowl, mix the butter, flour, brown sugar, and cinnamon with a fork until the mixture becomes crumbly. Stir in the chopped pecans.
-
Sprinkle the streusel mixture evenly over the sweet potatoes.
-
Bake for 10–12 minutes until heated through. Remove briefly from the oven, add the miniature marshmallows over the top, and return to the oven for another 5–6 minutes until the marshmallows are golden and toasted. Watch closely to prevent burning.
-
Remove the casserole from the oven and allow it to cool for about 5 minutes before serving.

Variations
You can easily adapt this casserole to suit different tastes. For a nuttier flavor, try replacing pecans with chopped walnuts or almonds.
If you prefer a less sweet dish, reduce the brown sugar slightly or skip the marshmallows and double the pecan topping for a crunchy finish.
For extra flavor, add a pinch of nutmeg or pumpkin spice to the sweet potato mixture. You can also mix shredded coconut into the streusel topping for a unique twist.
A dairy-free version can be made by substituting plant-based butter and milk alternatives such as almond milk or oat milk.
Storage/Reheating
Store leftover casserole in an airtight container in the refrigerator for up to 4 days.
To reheat, place a portion in the microwave for about 1–2 minutes until warmed through. For best texture, reheat in the oven at 350°F (175°C) for about 10–15 minutes.
If reheating the entire casserole, cover loosely with foil to prevent the marshmallows from burning while the center warms.
This casserole can also be frozen without the marshmallow topping for up to 2 months. Thaw overnight in the refrigerator before reheating and adding fresh marshmallows.
