How to make marshmallow sweet potato casserole

Step 1: Prepare the sweet potatoes by peeling them and cutting them into large chunks. Doing this will allow them to cook faster when you boil them instead of leaving them whole.

Step 2: Place the sweet potato chunks in a large pot and cover with water. Bring to a boil and cook the sweet potatoes until they are fork tender and fall apart easily.

Step 3: Drain the sweet potatoes and add them back to the sauce pan. Mash with a potato masher.

Add the rest of the casserole filling ingredients: butter, brown sugar, salt, cinnamon, vanilla extract, and nutmeg and mix until well combined.

Step 4: In a separate bowl, make the pecan topping for the casserole. Stir together the melted butter, brown sugar, all purpose flour, salt, and pecan pieces until combined.

Step 5: Grease a 9 by 13 baking dish with cooking spray. Add the sweet potato filling and spread it out evenly in the dish.

Top the sweet potatoes with the pecan crumble in an even layer.

Step 6: Add the mini marshmallows over the pecan topping in an even layer, making sure to cover the entire top of the casserole.

Step 7: Bake the sweet potato casserole at 350 degrees for 25-35 minutes, or until bubbly and the marshmallows are golden brown on top.

We are going for those perfect toasty brown marshmallows that make for the most delicious bite!

Just make sure to keep a close eye on the casserole towards the end to ensure you get a nice toasty brown top without burning.
