Sweet Potato Casserole with Pecan Streusel is a beloved dish that graces many holiday tables, especially during Thanksgiving and Christmas. Creamy, smooth mashed sweet potatoes form the base, lightly sweetened and spiced with cinnamon, nutmeg, and vanilla. On top, a golden-brown streusel made from butter, brown sugar, and chopped pecans adds a delightful crunch and a nutty, caramelized flavor that contrasts beautifully with the soft interior.
This casserole is more than just a side dish – it often feels like dessert disguised as dinner. The natural sweetness of the sweet potatoes is enhanced by a touch of sugar and warm spices, while the pecan topping provides texture and richness. Some versions include a splash of orange juice or zest for brightness, or a bit of bourbon for depth and complexity. Whether baked in a deep dish or spread into a shallow pan for extra topping, this dish brings warmth and comfort in every bite.
Its roots in Southern cooking give it a nostalgic charm, and its versatility allows it to shine alongside roasted turkey, glazed ham, or even as part of a vegetarian spread. While some families prefer marshmallows on top, the pecan streusel offers a more grown-up and flavor-forward alternative that appeals to a wider range of palates.
Sweet Potato Casserole also holds up well when made ahead, making it ideal for busy holiday meal prep. Reheated, it tastes just as good, if not better, the next day. Leftovers can be served with breakfast or as a sweet side for lunch, and they’re even tasty straight from the fridge.
From its smooth, spiced filling to the buttery, crisp topping, Sweet Potato Casserole with Pecan Streusel is a dish that balances decadence with wholesomeness. It’s a time-honored favorite that invites second helpings and brings a sense of home and celebration to the table.

I don’t know about this recipe… Sweet potatoes and sugar? Seems kinda odd to me. I might stick with normal potatoes for my casseroles.
This recipe is amazing! The pecan topping really adds a nice crunch to the dish. I made it for Thanksgiving and everyone loved it!
This casserole was everything I hoped for! The sweetness was spot on and the pecans added a nice crunch. Highly recommend!
I’m glad you enjoyed it! I’m thinking of trying this recipe for Thanksgiving. Do you think it would work with walnuts instead of pecans?
Sounds good but why’s everyone raving about pecans? They’re just nuts, right? Can you really taste the difference?
I found it too sweet! I think I might reduce the sugar next time. Also, I used walnuts instead of pecans because that’s what I had.
I guess it really depends on personal taste! I like it a bit sweeter myself, but walnuts are a great swap! Hope it turns out good next time!
Not bad, but the texture was kinda gummy? Maybe I mashed too aggressively or didn’t drain long enough after boiling. Flavor was great, just needs tweaking.
Pretty good, but mine came out a bit too sweet. Next time I’ll cut the granulated sugar in half or reduce the brown sugar in the streusel. Still worth making though.
Y’all, this is like a sweet potato pie without the crust! Love the nuts on top! 😍
I totally agree! The pecans really do add that nice crunch! This dish is so good, I can’t stop eating it! 😋
Sweet potato pie without crust? Sounds off to me. Why not just make pie then? Guess people got different taste…
Super yummy! My kids devoured it, even the picky eaters! Thanks for sharing!
I tried this and my kids just picked the pecans off! Not a fan of sweet potatoes. Maybe less sugar next time?
So glad to hear your kids loved it! It’s always a win when picky eaters enjoy something healthy! 😊
Was okay, but my topping didn’t get golden brown. What did I do wrong? 🙁
I’m not sure about using sweet potatoes…they taste funny to me. Should I try it?
I thought it was too sweet for my taste. Maybe cut down on sugar next time?
Meh, not what I expected. The texture was off. Should I have used less milk?
Sweet potatoes + pecans = my fave! Will make this every Thanksgiving!
This recipe is fantastic! My family loved it, especially the pecan topping. Definitely a keeper.
This casserole is a game changer! The pecan topping adds such a nice crunch. My family loved it.
Is it really that great? Sounds a little too sweet for my taste.
I totally agree! The pecan topping really takes it to the next level! 😍
Why use brown sugar when regular sugar is the same? Idk, seems pointless lol.
My mom used to make this every holiday! It always brings back memories.💕
This was pretty good but I mixed up the eggs and flour ratio. Oops!
2 large eggs seems like a lot? I worried it would turn into like custard, but it actually held together well. Next time I might try one egg just to test.
Totally disagree on reducing eggs. Sweet potato casseroles need that binding or the texture gets watery. But testing with 1 egg next time could be fine if you watch it closely.
Yeah I used to think 2 eggs was a lot too, but honestly sweet potato is pretty forgiving. Glad yours held together—custard worry is totally real though.
Nice recipe, but I used coconut oil instead of butter. Still turned out fine.
Honestly, I found it too sweet. Maybe cut down on the sugar next time. 🤔
I agree! It was way too sweet for my taste too. Maybe next time I’ll try half the sugar. 😅
Absolutely delicious! This recipe is a hit at every family gathering. I will make it again for sure!
I’m glad to hear that! This casserole is such a crowd-pleaser. Have you tried adding marshmallows on top? It’s a game changer!
I dunno about this… sweet potatoes with sugar? Sounds weird to me. My family likes it savory.
I’m skeptical of casseroles with lots of sugar, but wow. This was surprisingly balanced once baked. The golden topping helped a lot.
I didn’t have pecans, so I used walnuts. Wasn’t as good, but still edible. Next time I’ll follow the recipe properly.
Sweet potato casserole is just gross. Don’t understand the hype. 🤷♂️
I thought this recipe was a bit complicated for a newbie cook like me. Had to look up what ‘medium’ meant in eggs. But it turned out alright.
This is delicious! I made it for Thanksgiving and everyone asked for the recipe. The mashed sweet potatoes set really nicely after baking.
Thank you! Love hearing the mashed sweet potatoes set up nicely after baking—exactly what I was hoping for. Glad everyone wanted the recipe!
Meh. Too rich for me. :/
This recipe is amazing! We made it for Thanksgiving and everyone went crazy for it! Definitely a keeper! 🍠🥳
Made this for Thanksgiving and it was a hit! Way better than those canned ones I used to make.
I replaced pecans with almonds, and it still tastes good. Just an idea for those allergic to nuts.
That’s a great idea! I’m allergic to nuts too, so I’ll definitely try almonds next time.
Almonds? Really? They taste way different than pecans. Hope it doesn’t ruin the recipe.
I don’t know, it was just too sweet for my taste. Maybe I added too much sugar? Not for me.
Need simpler recipes for people like me! Can it be made in the microwave???
I hear ya! Sometimes these recipes are way too complicated. And microwaving sounds quicker. Could work, right?
SO good. Sweet potatoes are like nature’s candy! Yum!!
I followed the steps and it was easy. Only thing: I think boiling time depends on potato size, so 20 minutes wasn’t quite enough for my cubes. I baked another 5 minutes and it was fine.
Hmm 20 minutes seems short to me. My cubes took like forever (maybe I cut them too big). Also I noticed it thickened more after baking—next time I’ll check doneness instead of the timer.
Totally agree—sweet potato cube size makes a big difference. I usually just keep boiling until a fork slides in easily. Love that you adjusted with the extra 5 min!
This turned out *so* comforting. The pecan streusel is the star—crispy on top but still creamy underneath. I added a pinch of cinnamon too and it tasted like holiday season in a dish.
Yes!! I love when the streusel stays crunchy on top but the casserole is still creamy underneath. That pinch of cinnamon sounds perfect—definitely trying that next time. Thanks for the holiday-vibes tip!
Okay but like, why does it call for brown sugar AND granulated sugar? Seems like overkill. 🤔
I think both sugars add different flavors and textures to the dish! Brown sugar gives it that nice caramel taste 😋.
Wait, sweet potatoes are actually good in dessert? I was sure it would be nasty. Turned out alright tho. 😅
Yum, this is the best sweet potato dish I’ve ever made! So easy and the flavors are perfect. 👍
I used walnuts instead of pecans (because that’s what I had). It worked, but the flavor isn’t the same. Would definitely go back to pecans though.
I did walnuts once and thought it tasted fine tbh. Maybe your casserole got a little more “earthy” than “sweet”? Next time try adding an extra splash of vanilla or a pinch of cinnamon so it’s closer to pecan flavor.
Good to know! I’m always swapping nuts based on what’s in the pantry. Walnuts usually work, but yeah—pecans have that sweeter, buttery vibe. I’ll stick to pecans next time.
My topping clumped—maybe I didn’t use soft enough butter. Still tasted good, just looked rustic. I’d make again and just break up the butter more.
Hmm I don’t know… I feel like using melted butter in the casserole might make it wetter and then the topping clumps anyway? I usually bake without the flour in the streusel—more like just pecans + brown sugar + butter. Still, rustic is fine lol.
That makes sense—if the butter wasn’t softened enough, the streusel kind of turns into bigger clumps instead of a nice crumb. Next time, try breaking up the butter into smaller pieces before mixing, and it should stay more even. Glad it still tasted good though!
