Take your sweet potato casserole up a notch by replacing the traditional marshmallow topping with a crunchy brown sugar and pecan streusel.
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 is always a big hit. It’s an old Southern specialty 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 A sweet potato casserole
Heads up: most grocery stores 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 supermarket, so if you see “yams,” you’re probably looking at sweet potatoes.
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 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.
If you’d like to break up the preparation of this dish a bit, feel free to make and refrigerate the streusel a few days ahead. Or, if you really want to get a head start, assemble and refrigerate the whole casserole up to two days ahead of time. Bake right before serving for best results.

My husband loves him some pumpkin pie, but at my son’s request, I made this sweet potato casserole. My husband no longer needs pumpkin pie for Thanksgiving. He wants this! He and my son devoured it. Thanks for sharing this delicious recipe.
Made this yesterday! I wanted to substitute winter squash for sweet potato because I had one from my CSA. I chose your recipe because unlike most others you provided a weight measurement for the sweet potato, which let me convert it to squash and feel like I was using the right amount. Other than that, followed as written. It was very very delicious. Thank you!
Delicious side dish!thanks
I made the sweet potato casserole for the first time for thanksgiving dinner yesterday. It was the hit of the meal! Everyone raved about it and fought over who got to take home the few leftovers. My 89 year old mother-in-law said it was the best potato dish she had ever eaten and demanded I send her the recipe. Thanks so much.
My go to Thanksgiving sweet potato casserole though I use vegan butter and almond milk to accommodate some family members. I always start by baking the sweet potatoes which I think brings out the natural sugar. The addition of some nutmeg and cinnamon really takes them up. a notch. Cannot beat this praline topping.Thanks for a great, dependably delicious recipe that banishes marshmallows back to hot cocoa where they belong! Happy Thanksgiving, Jenn—grateful for all your great recipes!

Hi Jenn
If I make the sweet potato casserole ahead of time do i wait to bake it or bake and then reheat?
Thank you for all your amazing recipes
This is my sons favorite
Glad your boys like it! I’d assemble it and then bake before serving. Enjoy!
Does the casserole dish need to be greased?
Thank you!
No, it’s not necessary. Enjoy!
What could we substitute for pecans? We have a child with tree nut allergies.
Hi Deb, you can jut omit them or replace them with oats. Hope you enjoy!
Very similar to my sister’s recipe, only difference is she adds a splash of fresh squeezed orange juice. It brings a touch of zing and cuts the sweet.
Hope you don’t mind the suggestion… Ground oats, oat flour, can be substituted for the processed flour.
