Boil the Sweet Potatoes: Cook the sweet potatoes until they are fork tender, which typically takes about 15-20 minutes. They should crumble easily when pierced! This indicates they re ready for mashing.

Prepare the Pecan Topping: In a separate bowl, whisk together the melted butter, brown sugar, flour, salt, and pecan pieces. Mix until crumbly, giving you a deliciously crunchy topping!
Grease the Dish: Lightly grease a 9 by 13-inch baking dish with cooking spray to prevent sticking and make cleanup a breeze.
Add Sweet Potato Filling: Pour the creamy sweet potato mixture into the prepared dish, spreading it evenly. This base is where all the magic begins!
Top with Pecans: Sprinkle the pecan topping evenly over the sweet potato layer, ensuring every bite has that satisfying crunch.
Add Mini Marshmallows: Layer the mini marshmallows generously across the top, covering the pecan mixture. This is where the gooey goodness happens!
Bake and Enjoy: Place the casserole in a preheated oven at 350 °F for 25-35 minutes, or until it s bubbly and the marshmallows are golden brown. Let the aromas waft through your home, creating an atmosphere of comfort!
