How to Make Sweet Potato Casserole with Marshmallows
Prep the Sweet Potatoes: Start by preheating your oven to 350°F (175°C). Then peel and chop about three large sweet potatoes into chunks. Boil them in salted water until fork-tender, which usually takes around 15-20 minutes.

Add Flavorful Ingredients: Mix in softened butter, brown sugar, milk, vanilla extract, cinnamon, and a pinch of salt until everything melds into a luscious mixture that smells divine.
Transfer to Baking Dish: Pour your sweet potato mixture into a greased baking dish. Spread it evenly so every corner gets its fair share of that deliciousness.
Add Marshmallow Topping: Generously sprinkle mini marshmallows over the top of your casserole. Feel free to add more than you think necessary—this is where the magic happens!
Bake Until Golden Brown: Place your casserole in the oven and bake for about 25-30 minutes until the marshmallows are golden brown and slightly toasted—watch closely so they don’t burn!
