There’s something magical about walking into a kitchen where Sweet Potato Casserole with Marshmallows is bubbling away in the oven. Furthermore, the golden marshmallows on top create an irresistible aroma that instantly transforms any house into a warm, welcoming home. Moreover, this beloved dish has graced American tables for generations, and today I’m sharing my foolproof version that’ll have your family asking for seconds.
The Thanksgiving Lesson I’ll Never Forget
Let me tell you about the time I nearly ruined Thanksgiving dinner at my cousin’s house in Georgia. Additionally, I was twenty-five, fresh off my food truck adventures, and convinced I could reinvent the classic Sweet Potato Casserole with Marshmallows. Consequently, I added exotic spices, swapped the marshmallows for some fancy topping, and basically turned a beloved family recipe into something completely unrecognizable.
The silence at that dinner table was deafening. However, my great-aunt Ruby, bless her heart, took one bite and said, “Honey, sometimes the old ways are the best ways.” Subsequently, she pulled out her handwritten recipe card, yellowed with age and splattered with decades of kitchen love. That’s when I learned that Sweet Potato Casserole with Marshmallows isn’t just a side dish; it’s a tradition that connects us to our roots.
Since then, I’ve made this Sweet Potato Casserole with Marshmallows countless times, tweaking it just enough to make it my own while respecting the classic flavors that make it so special. Therefore, every time I serve it, I remember Aunt Ruby’s wisdom and the importance of honoring the recipes that have brought families together for generations.
Now, whenever I prepare this Sweet Potato Casserole with Marshmallows in my Asheville kitchen, I think about all the hands that have stirred similar mixtures before mine. As a result, it’s become more than just a recipe, it’s a way to pass down love, one golden, marshmallow-topped spoonful at a time.

Timing
This Sweet Potato Casserole with Marshmallows takes just over an hour from start to finish, which is actually 25% faster than many traditional recipes that require roasting the sweet potatoes first. Instead, boiling them cuts down significantly on prep time while still delivering that perfect creamy texture.
The beauty of this timing is that you can easily fit it into your holiday cooking schedule. While the casserole bakes for 35 minutes, you’ll have plenty of time to work on other dishes, like these easy Thanksgiving Appetizer Deviled Eggs, or simply enjoy a cup of coffee and watch the magic happen through your oven window.
Step-by-Step Instructions
Step 1: Prepare the Sweet Potatoes
First, peel and cut your sweet potatoes into large chunks, then place them in a large saucepan. Cover completely with water and bring to a rolling boil. This method is my favorite because it’s faster and more consistent than roasting, plus you won’t heat up your whole kitchen.
Step 2: Cook Until Fork-Tender
Boil the sweet potatoes for about 15-20 minutes until they’re fork-tender and easily pierced. They should practically fall apart when you touch them with a fork. Don’t worry about overcooking them slightly, it’ll make your mashing easier!
Step 3: Mash and Season the Base
Drain those beautiful potatoes and add them back to the saucepan. Now comes the fun part, mash them with a potato masher until smooth. Then, mix in the melted butter, brown sugar, salt, cinnamon, vanilla extract, and nutmeg until everything’s perfectly combined. Taste as you go, this is your chance to adjust seasonings.
Step 4: Create the Pecan Topping
In a separate bowl, stir together the melted butter, brown sugar, flour, salt, and chopped pecans until they form a crumbly mixture. This topping adds incredible texture contrast to the smooth sweet potatoes.
Step 5: Assemble the Casserole
Grease your 9×13 baking dish with cooking spray, then spread the sweet potato mixture evenly across the bottom. Next, sprinkle the pecan topping over the sweet potatoes, making sure to cover the surface evenly.
Step 6: Add the Marshmallow Magic
Top everything with an even layer of mini marshmallows. Don’t pack them down, just let them sit naturally on top. They’ll spread and melt beautifully as they bake.
Step 7: Bake to Golden Perfection
Bake at 350°F for 25-35 minutes until the casserole is bubbly and the marshmallows are golden brown. Watch closely during the last 10 minutes to prevent burning, those marshmallows can go from perfect to charred quickly!

Healthier Alternatives for the Recipe
Want to lighten things up without sacrificing flavor? Try these smart swaps that I’ve tested in my own kitchen. First, replace half the butter with unsweetened applesauce, you’ll save about 60 calories per serving while maintaining moisture.
For a lower-sugar version, substitute half the brown sugar with mashed banana or pure maple syrup. The natural sugars provide sweetness while adding extra nutrients. Additionally, you can use coconut oil instead of butter for a dairy-free option that adds subtle tropical notes.
Consider swapping regular marshmallows for sugar-free versions, or try my favorite alternative: a topping made from chopped dates and toasted coconut. It’s naturally sweet and adds wonderful texture. Furthermore, adding chopped walnuts or almonds instead of all pecans increases protein while reducing costs.
Serving Suggestions
This Sweet Potato Casserole with Marshmallows pairs beautifully with traditional holiday fare, but don’t limit yourself to just Thanksgiving! Serve it alongside roasted turkey, glazed ham, or even grilled chicken for a comfort food twist on weeknight dinners.
For an elegant presentation, try serving individual portions in ramekins, it’s perfect for dinner parties and makes portion control easier. Moreover, this casserole makes an unexpected but delightful brunch side dish with eggs Benedict or French toast.
Temperature matters too! While it’s delicious hot from the oven, it’s equally wonderful at room temperature, making it perfect for potluck dinners and buffet-style gatherings. The flavors actually develop and meld beautifully as it cools.
Common Mistakes to Avoid
The biggest mistake I see home cooks make is not cooking the sweet potatoes long enough. Undercooked potatoes lead to lumpy, uneven texture that no amount of mashing can fix. Therefore, always test with a fork, they should practically fall apart.
Another common pitfall is over-mixing the sweet potato base. Once you add the seasonings, mix just until combined. Over-mixing can make the texture gluey rather than creamy. Similarly, don’t pack the marshmallows down, they need space to expand and brown properly.
Watch your oven temperature too! Too hot, and the marshmallows will burn before the casserole heats through. Too cool, and you’ll end up with pale, sad marshmallows that won’t have that gorgeous golden color we’re after.
Storing Tips for the Recipe
Leftover Sweet Potato Casserole with Marshmallows stores beautifully in the refrigerator for 4-5 days in an airtight container. However, the marshmallows will lose their fluffy texture, so don’t expect them to look exactly the same as when fresh.
For reheating, I recommend covering with foil and warming in a 325°F oven for about 15 minutes. This method maintains the best texture. Alternatively, microwave individual portions for 1-2 minutes, though the marshmallows won’t re-crisp.
You can also prepare this casserole completely ahead of time! Assemble everything except the marshmallows up to two days in advance, then add the marshmallows just before baking. This strategy is a game-changer for holiday meal prep.

FAQs
Can I make this Sweet Potato Casserole with Marshmallows ahead of time?
Absolutely! You can prepare the entire casserole up to two days in advance. Just hold off on adding the marshmallows until you’re ready to bake. Cover tightly and refrigerate, then add marshmallows and bake as directed.
What’s the best way to prevent lumpy sweet potatoes?
The key is cooking them until they’re completely fork-tender, almost falling apart. Also, make sure to mash them while they’re still warm, cold sweet potatoes are much harder to get smooth.
Can I use fresh marshmallows instead of mini ones?
Sure! Just cut regular marshmallows into smaller pieces or use about 6-8 large marshmallows. Mini marshmallows distribute more evenly, but regular ones work fine too.
How do I know when the marshmallows are perfectly golden?
Watch for a rich golden-brown color that’s deeper than tan but not dark brown. They should look toasted and slightly puffed. Start checking at the 25-minute mark to prevent burning.
Can I freeze this casserole?
Yes, but freeze it before adding the marshmallows. Wrap tightly and freeze for up to three months. Thaw overnight in the refrigerator, add fresh marshmallows, and bake as directed.
