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. Thank you for such an easy, delicious dish that we will enjoy for years to come!”
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.
Make-Ahead, Storage & Freezing Instructions
The assembled casserole can be refrigerated for up to 2 days or frozen for up to 3 months. If refrigerated, allow it to sit at room temperature for 30 minutes before baking. For a frozen casserole, thaw in the refrigerator overnight. In either case, add a few extra minutes to the baking time. For best results, bake just before serving.
For leftovers, cover the casserole with foil and reheat in a 350°F oven for about 20 minutes, or until warmed through. If you want a crispier topping, remove the foil for the last 5 minutes of reheating. It’s also delicious as a snack cold from the fridge!

Is there a way to make this GF an omit the flour? Is there a good substitute I can use instead? Thanks!
Hi Deek, you can replace the flour with gluten-free flour. Hope you enjoy!
For someone with a nut allergy (almonds are okay), what would you suggest as a suitable substitute in the topping? Would slivered almonds work or is there a better alternative?
Hi Erin, I do think you could get away with almonds here. Please LMK how it turns out!
I made this for the first time this Thanksgiving, and my husband BEGGED me to make it again for Christmas and again for his birthday! The topping is wonderful, but the mashed sweet potatoes themselves also have such a nice flavor. This is a must-make from now on for our holidays!
Since finding this recipe we have made it repeatedly because my family loves it! It’s gone in no time!! Thanks for sharing it!
Hey Jen! Would this recipe still be yummy without the nuts? (Allergic to them). Thanks!
Sure, Melissa. You can just omit the nuts here or use oats in place of them. Hope that helps!
This is among my favorites of Jenn’s recipes! I make it every holiday (even in the spring!) because it is such a crowd pleaser. I have even frozen it and used it well after making it and it is remarkably good out of the freezer – which says a lot about the quality of the recipe, since I have never been encountered another recipe with streusel that freezes well. Thank you for another phenomenal dish that everyone loves!
Delicious. Family members who typically don’t eat sweet potato casserole tasted and liked it after hearing others rave over how good it is. This is a keeper.
Typically, like others, we only have sweet potato casserole during the holidays. This is one of those recipes that breaks that tradition. My family loved it so much that we make throughout the year, usually accompanied by a pork roast. It is simple and satisfying.
This is such a hit at the holidays, whether its xmas, thanksgiving, passover, or any other holiday it is sure to be a hit and one of the fastest dishes devoured. The topping makes it so yummy.
If you need a new idea for sweet potatoes, try this.
I made this for Christmas, my kids loved it.
I’ve already bought a big can of Bruce’s Sweet Potatoes (Yams). I am sure I can just make your topping and put it on top, but should I add anything to the canned sweet potatoes, too? Thank you! Karen
Yes, I’d recommend adding the other ingredients (the butter, salt, sugar, nutmeg, and egg). Hope you enjoy!
Please don’t use canned sweet potatoes. I am so surprised people change up such a wonderful recipe. I would suggest you bake the sweet potatoes at 400 degrees for 1 hour, cool and peel. the flavor is amazing compared to canned sweet potatoes. Easy Peasy!!!!!!
