Give your holiday sweet potato casserole a major upgrade by swapping the marshmallows for a brown sugar pecan streusel—it’s a game changer!
When it comes to Thanksgiving dinner, I think most of us would say, “Don’t get fancy on me, just make the standards really special.” That’s why this down-home sweet potato casserole recipe is always a big hit. It’s an old Southern side dish that graces almost every holiday table. Instead of the traditional marshmallow topping (yes, a classic, but let’s be honest, a gourmet dish marshmallows do not make!), I cover the sweet potatoes with a crunchy brown sugar-pecan streusel. It absolutely makes the dish. Like many Thanksgiving sweet potato sides, it’s almost sweet enough to be dessert. In my house, it’s “that dish”— the one everyone reaches their fork into long after the meal is done.
“My mom and I used your recipe for Thanksgiving and loved it so much that we are making it again for Christmas.”
What You’ll Need To Make Sweet Potato Casserole
- Sweet potatoes – Note that most supermarkets use the names “sweet potato” and “yam” interchangeably. This can be confusing since yams aren’t sweet potatoes at all, but rather thick white tubers with dark brown skin. Chances are you won’t find real yams at the grocery store, so if you see “yams,” you’re probably looking at sweet potatoes.
- Unsalted butter – Adds richness and flavor to both the sweet potato base and the streusel topping.
- Salt – Enhances the flavor of the sweet potatoes and balances the sweetness.
- Light brown sugar – Sweetens the base and adds a warm, molasses flavor to both the sweet potatoes and the crunchy streusel topping.
- Ground nutmeg – Adds a hint of warmth and spice to the sweet potatoes, complementing their natural flavor.
- Eggs – Help bind the sweet potato mixture and give the casserole structure.
- Flour – The base of the streusel topping.
- Ground cinnamon – Adds a warm, spiced flavor to the streusel topping.
- Pecans – Incorporated in the streusel topping to lend a crunchy, nutty contrast to the sweet potato base.

Step-By-Step Instructions
Bring a large pot of water to a boil. Add the sweet potatoes and cook until soft and tender, 20 to 25 minutes. Drain and let cool.
In the meantime, make the brown sugar and pecan topping: Melt the butter in a medium bowl the microwave. (Alternatively, melt the butter in a small pan or over low heat and transfer to a medium bowl.)
Add the brown sugar, flour, and cinnamon.
Mix until well combined. It should look a little clumpy.
Add the chopped nuts, and stir to combine.
Place the cooked and drained sweet potatoes in a large bowl.
Mash with a potato masher or large fork until very smooth.
Add the melted butter, salt, and brown sugar and nutmeg.
Mix well, then add the eggs.
Stir to combine. It’s okay if it is not completely smooth.
Transfer the sweet potato mixture to a 2-quart baking dish and spread evenly.
Sprinkle the topping evenly over the sweet potato mixture.
Bake for about 40 minutes, uncovered, or until the topping is nicely browned. Let cool slightly before serving.

Can I use oil instead of butter?
Hi Annette, I like the flavor that butter adds but if you’re looking to avoid dairy, oil will work. Enjoy!
* I top the casserole with mini marshmellows. You need to keep an eye on the marshmellows til they appear toasted, at which time you need to remove the casserole from the oven. Be careful not to burn the marshmellows. The toasted mashmellow topping adds an extra touch to the sweet potatoe casserole.
