Chef's Pro-Tips
- Roast instead of boiling: Roasting sweet potatoes whole in their skins caramelizes natural sugars without diluting the flavor with water.
- Dual-topping harmony: Combining crunchy buttery pecans with miniature marshmallows satisfies both traditional family preferences.
- Watch marshmallows closely: Marshmallows brown very quickly during the final 5 minutes of baking; keep an eye on them so they toast to golden perfection rather than burn.

Step-by-Step Instructions
Prep Sweet Potato Base
Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish. Place cooked hot sweet potatoes in a large bowl. Add maple syrup, 4 tbsp melted butter, heavy cream, vanilla, cinnamon, nutmeg, salt, and beaten eggs. Beat with a hand mixer until creamy and velvety smooth.
Spread in Dish
Smooth the whipped sweet potato mixture evenly into the prepared baking dish.
Make Pecan Streusel
In a separate bowl, mix chopped pecans, brown sugar, flour, and cold cubed butter using a fork or pastry cutter until crumbly streusel clusters form.
Bake Casserole
Scatter the pecan streusel evenly over the sweet potatoes. Bake for 30 minutes until bubbling around the edges.
Toast Marshmallows & Serve
Remove from oven and scatter mini marshmallows over the top. Return to oven for 5-8 minutes until marshmallows are puffed and toasted golden brown. Rest 10 minutes before serving.
