How to Make Sweet Potato Casserole with Marshmallows & Pecans
Boil Sweet Potatoes: Begin by placing your sweet potatoes in a large pot filled with cold water. Cover the pot and bring it to a boil before reducing the heat to a simmer. Cook for 15-25 minutes until tender and easily pierced with a fork. Once done, drain and let them cool.

Mash Potatoes: In a large mixing bowl, mash the cooled sweet potatoes until they reach a creamy, smooth consistency. This will be the delicious foundation of your casserole!
Mix Sweet Base: Combine the mashed sweet potatoes with the light brown sugar, softened butter, vanilla extract, ground cinnamon, nutmeg, and a pinch of salt. Mix until all ingredients are fully incorporated and you have a rich, velvety mixture.
Transfer & Smooth: Carefully spread the sweet potato mixture evenly into the prepared casserole dish. Make sure to smooth the top for an even baking result.
Add Toppings: Sprinkle the remaining 1/4 cup of candied pecans and all the mini marshmallows generously over the sweet potato layer. This will create a delightful, sweet topping as it bakes.
Bake & Serve: Place the casserole in the oven and bake for 15 minutes or until the marshmallows turn golden brown and puffy. For a special touch, drizzle with maple syrup before serving if desired.
Optional: Add a sprinkle of cinnamon on top for an extra touch of warmth!

Sweet Potato Casserole with Marshmallows & Pecans Recipe FAQs
What type of sweet potatoes should I use for the casserole?
Absolutely! For the best results, choose sweet potatoes that are firm and free from dark spots. Look for those with smooth skin, as they tend to be sweeter and creamier. I recommend not letting them sit too long before cooking, as they can lose their sweetness.

Why are my sweet potatoes lumpy after mashing?
Very! If your sweet potatoes are lumpy, it could be that they weren t cooked long enough. Make sure they are tender enough to easily pierce with a fork before mashing them. Use softened butter for a smoother blend, and if lumps persist, you can use a potato ricer or food processor to achieve the desired creaminess!
Is this casserole suitable for people with nut allergies?
