Step‑by‑Step Instructions for Heavenly Sweet Potato Casserole with Gooey Marshmallow Topping
Step 1: Prep Sweet Potatoes
Start by peeling and cutting the sweet potatoes into large chunks. Place them into a pot of boiling water and cook for about 15-20 minutes until they are tender and easily pierced with a fork. This initial step lays the foundation for a creamy and delicious sweet potato casserole.
Step 2: Mash Sweet Potatoes
Once tender, drain the sweet potatoes thoroughly and return them to the pot. Using a potato masher or a hand mixer, mash the sweet potatoes until smooth and free of lumps. This will create a lovely base for your casserole, ensuring every bite is creamy and comforting.
Step 3: Mix Filling
In a large mixing bowl, combine the mashed sweet potatoes with melted butter, light brown sugar, cinnamon, nutmeg, vanilla extract, and a pinch of salt. Mix well until all ingredients are thoroughly blended and the filling is creamy. The aroma will instantly remind you of holiday gatherings as you prepare this sweet potato casserole.
Step 4: Prepare Baking Dish
Preheat your oven to 350°F while you prepare your baking dish. Grease a 9×13-inch baking dish with cooking spray to prevent sticking. This step ensures your Heavenly Sweet Potato Casserole bakes evenly and is easy to serve once it’s done.
Step 5: Layer Ingredients
Spread the sweet potato filling evenly across the bottom of the prepared baking dish. Make sure to smooth it out with a spatula for an even layer. Top generously with mini marshmallows, ensuring they cover the entire surface for a delightful, gooey topping that will melt and toast beautifully in the oven.
Step 6: Bake
Place the baking dish in the preheated oven and bake for 25-35 minutes. Keep an eye on it, as you want the marshmallows to achieve a golden-brown color. The casserole will be bubbly and fragrant, filling your kitchen with the comforting essence of the holidays.
Step 7: Broil for Extra Crispiness
For a final touch, you may opt to broil the casserole for an additional 1-2 minutes at the end of baking. This step will give your marshmallows a beautifully toasted finish, but be sure to watch closely to avoid burning.
Step 8: Serve and Enjoy
Once done, carefully remove the casserole from the oven and allow it to cool slightly. Scoop portions onto plates and savor the deliciousness of this Sweet Potato Casserole, perfect alongside turkey at your festive gatherings or as a comforting side dish during any meal.
