Let’s make it
Preparation
Preheat the oven to 180°C (350°F). Grease a 9x13 inch baking dish with butter or non-stick spray.
Sweet Potato Preparation
Place peeled and chopped sweet potatoes in a large pot and cover with water. Bring to a boil and cook until tender when pierced with a fork, about 15-20 minutes. Drain well.
Sweet Potato Preparation
Transfer the cooked sweet potatoes to a large bowl. Add granulated sugar, butter, milk, vanilla extract, and salt. Mash everything together until smooth and creamy.
Assembly
Spread the mashed sweet potato mixture evenly into the prepared baking dish.
Topping Assembly
In a small bowl, combine chopped pecans, brown sugar, and ground cinnamon. Sprinkle this mixture evenly over the sweet potatoes.
Baking
Bake the casserole in the preheated oven for 20 minutes, until the topping is set and slightly browned.
Marshmallow Topping
Remove the casserole from the oven. Evenly distribute mini marshmallows over the top.
Final Baking
Return the casserole to the oven and bake for an additional 5-7 minutes, or until the marshmallows are golden brown and toasted. Watch carefully to prevent burning.
Serving
Remove from oven and let stand for 5 minutes before serving warm as a delicious side dish.
Tips & notes
Use fresh sweet potatoes and mash while still warm for the smoothest texture. Toast pecans lightly in a dry pan before adding to heighten flavor. Watch marshmallows closely during final bake to avoid burning them.
Saving it for later
Store leftovers covered in an airtight container in the refrigerator for up to 3 days.
Reheating
Reheat individual portions in the microwave until warmed through. For best texture, reheat in a preheated oven at 175°C (350°F) for 10-15 minutes until hot and marshmallows are soft again.
