How to Make Sweet Potato Casserole with Marshmallows
Step 1: Prepare the Sweet Potatoes
First things first, let’s get those sweet potatoes ready! Start by peeling them and chopping them into large chunks. Aim for about 1-inch pieces to ensure even cooking. Place the chopped sweet potatoes into a large saucepan and cover them with water. Bring the water to a boil over medium-high heat. Once boiling, reduce the heat and let them simmer until fork-tender, which usually takes about 15-20 minutes. You want them soft enough to fall apart easily, so keep an eye on them!
Step 2: Mash the Sweet Potatoes
Once your sweet potatoes are tender, it’s time to mash! Drain the water and return the sweet potatoes to the saucepan. Grab a potato masher and get to work, mashing them until smooth. This is where the magic happens! Now, add in the melted butter, brown sugar, salt, cinnamon, vanilla extract, and nutmeg. Mix everything together until well combined. The aroma will be heavenly, and you’ll be tempted to sneak a taste!
Step 3: Make the Pecan Topping
Now, let’s create that crunchy pecan topping! In a separate bowl, combine the melted butter, brown sugar, all-purpose flour, and salt. Stir until everything is well mixed. Then, fold in the finely chopped pecan pieces. This topping adds a delightful crunch that perfectly complements the creamy sweet potatoes. If you want an extra layer of flavor, consider toasting the pecans lightly before mixing them in!
Step 4: Assemble the Casserole
It’s time to bring it all together! Start by greasing a 9 by 13 baking dish with cooking spray to prevent sticking. Spread the sweet potato filling evenly across the bottom of the dish. Next, sprinkle the pecan topping generously over the sweet potatoes. Finally, add a layer of mini marshmallows on top. Make sure they’re spread out evenly for that perfect gooey finish. Your casserole is looking delicious already!
Step 5: Bake the Casserole
Preheat your oven to 350 degrees Fahrenheit. Once it’s ready, pop your casserole in the oven and bake for 25-35 minutes. Keep an eye on it, especially towards the end! You want the marshmallows to turn a beautiful golden brown without burning. When it’s bubbly and the marshmallows are perfectly toasted, take it out and let it cool for a few minutes. Your Sweet Potato Casserole with Marshmallows is now ready to be devoured!

Tips for Success
- Make sure to mash the sweet potatoes thoroughly for a smooth texture.
- Adjust the amount of marshmallows based on your family’s preference for sweetness.
