How to Make Sweet Potato Casserole with Marshmallows
-
Prepare the sweet potatoes by peeling and cutting them into large chunks. Place them in a large saucepan and cover with water. Bring to a boil to soften.
-
Boil the sweet potatoes until they are fork-tender, around 15-20 minutes. They should easily fall apart when pierced.
-
Drain the sweet potatoes and return them to the saucepan. Mash them with a potato masher, adding the stick of butter to melt it. Mix in the remaining sweet potato filling ingredients until smooth and well-combined.
-
Make the pecan topping in a separate bowl. Stir together the melted butter, brown sugar, all-purpose flour, salt, and finely chopped pecans until everything is well-coated and crumbly.
-
Grease a 9 by 13-inch baking dish with cooking spray to prevent sticking.
-
Spread the sweet potato filling evenly in the greased baking dish, ensuring a smooth, even layer.
-
Top the sweet potatoes with the pecan mixture, sprinkling it evenly over the surface for a crunchy topping.
-
Layer the mini marshmallows evenly over the pecan topping for that quintessential sweet finish.
-
Bake the sweet potato casserole at 350°F for about 25-35 minutes. Look for it to be bubbly and the marshmallows to turn a beautiful golden brown. Keep an eye on it towards the end to avoid burning.
Optional: Serve with a sprinkle of additional cinnamon for added warmth.

Expert Tips for Sweet Potato Casserole
-
Choose the Right Potatoes: Use large, firm sweet potatoes for the best flavor and texture. Avoid any with soft spots or blemishes.
-
Mash Well: Ensure your sweet potatoes are thoroughly mashed and smooth before mixing in other ingredients. This prevents a lumpy casserole.
-
Don’t Overcook Marshmallows: Keep a close eye when baking. Mini marshmallows can burn quickly—remove them as soon as they reach that perfect golden brown!
-
Add a Hint of Spice: For an extra kick, consider adding a pinch of cayenne pepper to the sweet potato mixture. This pairs surprisingly well and enhances the sweet and savory profile.
-
Storage Tips: If preparing ahead, store the sweet potato filling and pecan topping separately until just before baking. It keeps everything fresh and prevents sogginess.
