    I remember the first time I ever made a sweet potato casserole. It was the second week on the job with a new client, and we were talking about the menu over the next couple of days, and she decided she wanted Thanksgiving in July!

    Well, I'm a firm believer that holiday food should be enjoyed at all times of the year because it's that good! So, after whipping up a recipe, the client was impressed and looked at me like she was ready for marriage.

    You read that right! Do not make this recipe unless you're ready to be loved for a long time. I know there's a big debate over pecans or no pecans, but a true sweet potato casserole has a pecan topping. The marshmallows are the thing I believe can stay or go.

    What is Sweet Potato Casserole?

    Sweet potato casserole is a popular side dish during Thanksgiving and Christmas. It is made with mashed sweet potatoes, butter, sugar, eggs, milk, and cinnamon. The mixture is then placed in a baking dish and topped with pecans and marshmallows. Then bake until the marshmallows are golden brown.

    Key Ingredients

    Before you start whipping up this sweet potato casserole, look at this list of ingredients to make sure you have everything you need for some delicious sweet potato casserole with marshmallows.

    Fresh Sweet Potatoes

    Never buy a fresh sweet potato with strings dangling from it. This is a sign that the sweet potato is old.

    Dark Brown Sugar

    I love the deep maple molasses flavor of dark brown sugar. However, you can use light brown sugar.

    Eggs

    The eggs will help the casserole firm up while it bakes.

    Unbleached All-Purpose Flour

    Flour helps the topping bind. Feel free to use gluten-free flour as a 1:1 swap.

    Evaporated Milk

    I like the extra sweetness that evaporated milk adds. You can taste the subtle difference in the final product. You can use any milk you have on hand.

    Marshmallow Fluff

    I wanted to try something different, so I used marshmallow fluff which gives the final product a creamier mouth feel that I’m a big fan of.

    Pecans

    It’s not a sweet potato casserole if there are no pecans. For a time, buy pre-chopped pecans, but if you’re like me and have them on hand, give them a quick chop.

    How To Make Sweet Potato Casserole Recipe

    I want my sweet potato casserole with marshmallows to be fun to make, bursting with flavor, and a crowd-pleaser.

    Sweet Potatoes: Preheat the oven to 350°F and place the oven rack on the second highest level. Add peeled and chopped sweet potatoes to a medium pot and cover with water. Place over high heat and bring to a boil; cook sweet potatoes for 15 minutes or until potatoes are fork tender. Drain, mash, and measure out 3 cups of sweet potatoes into a large bowl.

    Pecan Topping: Add brown sugar, unsalted butter, salt, and cinnamon, and mix them together. Add eggs, vanilla, and milk until smooth. Transfer to a butter 9 x 13 casserole dish.

    Assemble Casserole: In a large bowl, mix brown sugar, flour, butter, and pecans. Evenly spread sweet potato mixture in the dish. Bake for 30-40 minutes until the marshmallows are slightly brown and the casserole is bubbling. Cool for 10 minutes. Turn oven on low broiler before serving hot.

    Spread marshmallow fluff over sweet potato casserole, place on the top rack, and cook until fluff is brown; rotate pan if needed. Serve immediately.

    Pro Recipe Tips & Tricks

    Here are the best practices, techniques, substitutes, and flavor builders you'll need for the best sweet potato casserole.

    • If you’re short on time, use canned sweet potatoes, you will need (2) 29 oz. cans of sweet potatoes to make sure you have enough casserole.
    • Feel free to use gluten-free flour in place of unbleached all-purpose flour.
    • You can mash sweet potatoes with a fork or potato masher.
    • Baked sweet potatoes have more flavor than boiled, but it also takes 45 minutes longer.
    • The casserole is fully cooked once you notice that it has firmed up.
    • You can use traditional marshmallows or mini marshmallows instead of marshmallow fluff. Just add after you add the toppings.
    • I chose to use marshmallow fluff because traditional marshmallows are made with pork.
    • If you’re not a fan of pecans, a great substitute are oats, walnuts, or hazelnuts.
    • Using light brown sugar or granulated sugar instead of dark brown sugar will still produce a delicious final product.

    FAQs

    Here are the top questions readers have about sweet potato casserole with marshmallows.

    Do I need to add eggs to my sweet potato casserole?

    Yes! Adding eggs to your sweet potato casserole gives the dish a thicker structure, similar to sweet potato pie. Make sure your sweet potatoes are not steaming hot when adding the eggs to the dish because it will scramble the eggs.

    How can I spice up sweet potatoes?

    Sweet potatoes take on flavors very well. Adding cinnamon, nutmeg, or ground ginger and the right amount of salt to spice up your sweet potatoes.

    Do you need to wrap sweet potatoes before baking?

    No, that’s an unnecessary step. Use a fork to pierce the sweet potato evenly before baking. This helps the potato to release steam as it bakes, which allows the sweet potato's sugar to cook throughout the whole potato.

    Is it better to boil sweet potatoes before baking?

    Boiling sweet potatoes is a faster cooking process than baking. However, a flavor test will show that baked sweet potatoes have a better flavor. Steaming them is also another great option.

    Can I use something other than pecans for the toppings?

    Yes. I like to use oats, walnuts, or hazelnuts as a swap for pecans.

    Why do they put marshmallows on sweet potatoes?

    I believe a marshmallow topping is added to sweet potatoes because when they're cooked, the gooey marshmallows add a creamy taste and texture to the sweet potatoes.

    Can I make this in advance?

    Yes! You can bake the whole sweet potato casserole two days before you’re ready to serve. You can also make the sweet potato filling and toppings in advance. Keep them separate until you’re ready to bake.

    How to store sweet potato casserole?

    Sweet potato casserole is best 2 days after baking but will be fresh for 7 days in an airtight container in the fridge. I wouldn’t recommend freezing it, but you can freeze it by placing it in a freezer-safe container for 3 months.

    Reheat the casserole in a 350°F oven for 10-12 minutes or until hot.
