Instructions
Cook sweet potatoes: In a large stockpot, cover sweet potatoes with cool water. Bring to a boil. Cook until potatoes are fork tender, about 15-20 minutes. Drain.
Mix casserole ingredients: Mash sweet potatoes in 9x9 inch baking dish. Mix in crushed pineapple, brown sugar, pecan pieces, and pumpkin pie spice. Dot with small pieces of butter and stir. Spread mixture evenly in pan. Cover with marshmallows (that is, whatever's left after your kids steal some) and press into sweet potato mixture. Cover with aluminum foil.
Bake: When ready to cook, preheat oven to 350°F. Cook until heated through, 30-45 minutes (depending on whether the casserole had been stored in the refrigerator).
Broil: Once the sweet potato casserole is fully heated through, remove the foil, change the oven to broil, and remove as soon as the marshmallows turn golden brown. Be careful - this happens quickly. Serve hot.

Notes
Make ahead directions: This sweet potato casserole can easily be made ahead by preparing all the way up until the point where it is covered in foil. Instead of baking immediately, store in the refrigerator over night. Place in the oven to cook when ready. To reduce cooking time, allow casserole to come to room temperature before placing it in the oven.
