The Classic Thanksgiving Side Dish (Or, Dessert?)
You guys, the strange thing about this sweet potato casserole is that it is very much a dessert, but never once in my Thanksgiving career have I experienced this being served as anything other than a completely luscious side dish to accompany the mashed potatoes and gravy, turkey, green bean casserole, and soft white dinner rolls. The flavor just works. It’s that one little pre-dessert side that you might even like more than your real dessert.
This is a recipe that my mom has been making for years, and she got it from one of her friends who has been making it for years before that, and there is a reason is has become a mainstay at Thanksgiving.
First, let’s talk toppings. 👇🏼
Topping For Sweet Potato Casserole
I like to Easy Button my life whenever possible, so I just toss all the topping ingredients in my food processor and give it a go-round till it makes that crumbly, streusel-like topping that we know and love.
We’re talking just four easy ingredients:
- Brown sugar
Now, we know some love the sweet fluffy topping of marshmallows, but the texture of this sweet, nutty, crumbly topping just CANNOT BE BEAT. The crunchy topping perfect balances the fluffiness of the mashed sweet potatoes, and just… wow. Trust us, we’ll make a convert of you.
Okay, we’ve got the topping.
Now the base.
Ingredients In The Sweet Potato Casserole Base
The sweet potato mixture is as easy as mixing up a muffin batter.
All you need to do is mix all this together:
- Sweet potatoes (CANNED, which I know seems so retro and perfect and that’s because it is – I’ve made this with non-canned sweet potatoes, and the weight of baked or boiled sweet potatoes is just too heavy, trust me on this one)
That’s it! Now let’s get this in the oven and on the table.
How To Make This Easy Sweet Potato Casserole
We’ve got our topping, we’ve got our base, and now it’s time to bring it all together.
It’s this easy:
- Mix and pour your sweet potato mixture into a pan.
- Top it with your beloved crumble.
- Bake for 30-45 minutes to get that topping nice and crispy.
And then? The moment of Thanksgiving sweet potato casserole truth.
YOU’RE A HERO.
The soft and sweet bottom layer + the crunchy and nutty top layer work their magic together to make the best sweet potato casserole that you could ever want for your Thanksgiving side-dish domination.
I can’t wait for you to love this one.
Frequently Asked Questions: Sweet Potato Casserole
Yes! We actually enjoy the texture of the canned sweet potatoes here, but fresh would work as well. Would recommend that you bake them instead of boil if you go the fresh route as to not add more moisture.
The eggs in the sweet potato casserole are what binds it all together without making the base too heavy. Without them, the casserole wouldn’t be quite as fluffy and scoopable!
We couldn’t have explained it better than The Spruce Eats. In this recipe, we’re technically using orange sweet potatoes.
Yep, that should work just fine! Prep it all as listed, and you can refrigerate for 1-2 days before baking. If you want to make it even better, you could also wait to sprinkle on the topping until it’s time to bake.
To make this vegan, you can sub the butter for vegan butter, the milk for your favorite plant-based unsweetened/unflavored milk, and omit the eggs.
Sub in a gluten-free flour (like almond flour) for the all-purpose flour in the topping.
Like most foods being served, this should not sit out for more than 2 hours according to the USDA. After that it should either head to the fridge or be tossed!
Store in the fridge in a covered container (either the dish it was baked in or a new container). It will keep in the fridge for 3-4 days, but best sooner than later! To reheat, you can cover it and pop it in the oven again, uncovering it for the last few minutes to crisp it up, or you can hit the easy button and just reheat in the microwave. It won’t be quite as crispy but still delicious!

Lindsay, you had me at sweet potato. I am addicted to orange vegetables and fruit. Pinning it to try later. Thank you.
I want to face plant into that crumble. Easy recipes for the win! Good luck with moving!
How many whole sweet potatoes is that? I’m not sure how to measure them out since I’m not using canned
Most recipes call for 3 to 4 medium sweet potatoes. I like it better with fresh sweet potatoes rather than canned.
Great question. We haven’t tested this recipe using whole sweet potatoes. You could try cooking 4 medium sweet potatoes and then weighing them after they’re mashed to ensure they’re around 29 ounces!
Definitely need this in my life. That crumble is awesome!
I think my mom uses this same recipe! LOL! Obviously, the measurements are a little (Like just a tad!) different, but some idea! Love it!
Haha awesome! Moms know!
Dads too, check out my post LOL…
That looks so amazing! I use canned pumpkin all the time, so I’m not freaked out by the idea of canned sweet potato. It must make things WAY easier, and is probably smoother! Good luck with your move! Moving is kind of the worst, but setting up the new place will be fun. Do you have a great window for food photos? Can’t wait to see the pics!
Haven’t tried any of the windows yet but I’m just happy to have TWO in the kitchen after having none for so long! They’re small but they’re windows!! 🙂
Do you use the plain yams in a can or the sweet potatoes in light syrup? Also, if i double do i adjust the cooking time?
I’d like to know the same thing! Have canned yams but no vanilla.
I’ll have Lindsay get back to you, Etta!
Yes, if you double it I’d bake it a bit longer. Just check it periodically – it is going to be mushy even when fully baked, but judge it based on the topping (should be pretty deep brown and crisped up a little bit when done). Any yams will work! We use the Nature’s Pride old-school looking can with sweet potatoes in it. I believe there might be some syrup in there.
What a lovely and easy recipe!
You just took me to my happy place! My mom’s sweet potatoes are my favorite Thanksgiving side (if you threatened to take away my pie and forced me to choose just one that is), but now I want to add this recipe to the mix as well. I mean, pecan crumble? Oh yes.
What a great side dish. It looks great served right out of the pan too
I literally just texted my Mom asking if I can be in charge of the sweet potatoes- we have to claim things we want to cook ahead of time for Thanksgiving in our family- and she said yes 🙂 Crumbly, yummy goodness here I come!
Ho-lee crap. I’m not normally a fan of overly sweet casseroles at Thanksgiving (ugh, with the mini marshmallows) but I could 100% get behind this dish. I night even bring myself to buy canned sweet potatoes! (this exists? really?) But that crumble topping…. that’s the nail in the coffin right there. Yes, please!
I make something similar, but I have to try yours. You are right the sweet potato dishes are an awesome treat on your plate for thanksgiving
We have done something similar for close to 40 yrs. I really think the apple pie spice makes it yummy! Although sometimes difficult to find, you can substitute some cinnamon, nutmeg, ginger, cardamom, etc. I also make a double batch of the topping because it is crazy good. We often bake the casserole the day(s) before, let it cool, and refrigerate. I usually pull it out of the oven a bit early just so it won’t burn the next day when I re-heat it. So, you re-heat it for a few minutes in the oven, then make the topping, sprinkle on top and toss it into the broiler. This frees up your oven for some of the other holiday dishes. Whichever MAGICAL recipe you make, you will LOVE it. I usually have half a bite of regular mashed potatoes on my fork with half a spoonful of the sweet potatoes. (Mouth watering ~ NOW!) Oh, and the leftovers (if there are any) can be heated in the microwave. DO IT! You will be the hit of the party even with people who normally don’t like (*gasp) sweet potatoes. I use a 13×9 dish…I like having more surface area for the topping!
Sweet Potato “Soufflé”
2 ½ c. canned sweet potatoes, drained & mashed
½ stick butter
1 1/2 c. sugar
¾ c. evaporated milk
1/3 c. water
1 t. apple pie spice
1 t. vanilla extract
Preheat oven to 350 degrees.
Mix ingredients together until almost smooth. Bake 1 ½ hours or until inserted knife comes out clean. Broil 1 min. with topping (I double the topping recipe. This is a single recipe below):
2 T. sugar
2 T. flour
1 t. apple pie spice
½ c. chopped nuts
2 T. margarine or butter, softened
Hi Donna! That’s what we call it too but I changed the name here just for search purposes. I think in general people are more familiar with sweet potato casserole than souffle. The recipe looks really similar! I doubled the topping too as you can see in this recipe. 🙂
We make this every year… Except we bake it with some shredded coconut… Yummm!!!
Thank you so much for sharing these recipes…and for the work you put in to the blog/site and giving the little details to ensure we have a successful turnout on our recipe attempts. I’m always so grateful for these resources we have available
to us thanks to other people’s time and efforts.
Ihave to confess…kind of drives me a little tiny bit or a lot crazy when someone comes to the reply section and uses it as their platform to indirectly critique someone else’s efforts by elevating their own agenda and “knowledge” about how they already know all you’ve shared, have a better way of doing it, a better name to call it, and suggest so many substitutions or exchanges, that it completely changes the recipe. It’s confusing to the followers and just seems a little…or a lot, out of place. Don’t get me wrong. I don’t mind helpful additional thoughts or ideas that stem from an original post such as helpful tips, or minimal substitutions that might be useful in place of an ingredient harder
to find or a “crunchier” option for those who have more organic items on hand. But all of that can be done with tact, class, social ediquette, while keeping the writer’s recipe at the center of the post, without using the reply section as a whole new platform for their own recipes and opinions. Changing your recipe completely, comes across as an attempt to “one-up or belittle” the writers efforts and tends to give the impression That they feel their ideas or recipe, are in some way, superior and deserve a “place” on your blog. I have no doubt that other people have similar recipes with some great ideas. But, they fortunately, also have the same opportunity and resources available to start and write their own food blog, without having to take the easy way out of the work and instead, trolling others sites to promote or brag on themselves.
Just my two cents..You guys don’t always get the appreciation you deserve. Thank you for this and I will be trying it just as shared…without 13 other spices and alterations. Would it even be the same recipe if I did that? LOL.
Thanks again. -a lot of time and work goes into what you do.
Came Across this recipe (was actually looking for THIS recipe specifically and THANK GOODNESS it happened to be the VERY 1st thing that popped up on the search engine page! 🙂
BUT, I did notice while scrolling through the comments (just seeing what everyone else might’ve said regarding THIS recipe specifically and actually trying to find out which brand of canned sweet potatos to use, which indeed had already been asked and answered, THANKS BTW 🙂 ), when I noticed a “comment” that was PRETTY MUCH almost a complete BLOG POST within itself with an entirely different RECIPE listed with a completely DIFFERENT list of ingredients, along with allll of THEIR little different “tips & tricks” SPECIFICALLY FOR THE RECIPE THEY POSTED ONLY! Which was a completely different recipe than the recipe and blog post here!! I ALSO FOUND THAT QUITE DISRESPECTFUL MYSELF!!
This comment/reply will probably NEVER be seen considering its 2018 almost 2019 and this a pretty old post from several years ago, but I HOPE IT DOES AND I HAVE TO AGREE WITH THE COMMENT ABOVE!! It is different to comment or add little tweaks or suggestions regarding this original blog post/recipe but to comment “YOUR OWN” entirely different recipe made different with a whole list of different types of ingredients etc is just so disrespectful in my opinion.
If you’d like to share YOUR OWN PERSONAL FAVORITE RECIPE OF SOME KIND THAT HAS NOTHING TO DO WITH THE RECIPE IN THIS BLOG, IN MY PERSONAL OPINION, THEN MAYBE YOU SHOULD GO CREATE YOUR OWN BLOG POST SHARING THAT RECIPE ALONG WITH ALL OF THE DIFFERENT INGREDIENTS ETC YOU LIKE TO USE AND HOW YOU LIKE TO MAKE SOMETHING YOUR WAY, ON YOUR OWN BLOG/POST/PAGE/WEBSITE!
Say what what whatttt?! I’ll take this dish and a spoon please and thank you!
That looks absolutely amazing! I only love sweet potatoes around thanksgiving. I don’t know why. Next week I’ll be whipping up some sweet potato yumminess.
Thanksgiving is the one time of year we don’t have to apologize for using ingredients that may otherwise be shameful (I still use canned green beans for green bean casserole, and I’m never going to stop!). I love that Thanksgiving evokes those traditions from all of us. I love love love this, I can’t even imagine how amazing it tastes if it’s as good as it looks! Heaven.
THE best part of the whole meal! You’ll love it!
Yum I can smell this through the computer, I swear!
This is one of my favorite ways to make sweet potatoes….but we usually save it for special occasions. And I agree…you have it as part of the meal and then go back for seconds…and then thirds. Hmmm…how about the leftovers (rarely) for breakfast????
I could eat this with a spade! Which means the quantitites would have to be quadrupled!
I have been making this dish for the last 25 years. I never heard it referred to as a crumble ,as my recipe was called Sweet Potato Souffle. It is delicious! So glad others are finding out about it! I have to make two casserole dishes of it because guests always want some to take home and then I never have any leftover!!! Enjoy!
Yes! That’s actually what we call it too but I just re-named it for search purposes. 🙂 🙂
Miss Lady thank you is all i can say……I’m a cook not a baker but this is a must try…..Yippie Skipping to the store……..????????????????
My very favorite Thanksgiving dish is my mom’s candied sweet potatoes. Just something about the way mom’s make them, right? Or maybe it’s the sugar too. 😉
I’d love to try your mom’s signature sweet potato casserole! And you definitely can’t beat 8 minutes.
Anything with sweet potatoes is a win and anything with a buttery brown sugar crumble is a win so the two put together are a major win! The classic passed-around recipes are often the best! This looks so delicious!
I love old family recipes – thanks for sharing your story behind this recipe, I could almost smell the pine trees! What an awesome experience that must have been at Christmastime!
I love that you made this in a cast iron skillet!! Great idea. I finally purchased one a few months ago and am still experimenting with it. Can’t wait to make this. Have a great weekend!
This looks really good, thanks for sharing your mum’s recipe! One question though, is the 3 cup measurement for the already mashed potato or for the potato pieces before they are mashed? We don’t have canned sweet potato in Greece so I’ll be making it from scratch. Many thanks!
Good question. I think it would be three cups mashed, which was how I did it when I made them with non-canned sweet potatoes. The cans come in the perfect size, so I just know my mom always uses that same size which was why I didn’t specify that in the recipe. I’ll clarify that.
I’m on my way to buy a cast iron pan and cans of sweet potato !!!!! It just looks so earthy and rustic oh and not to mention really yummi thanku …..
I have made something similar for many years, but using regular sweet potatoes. The secret is that you need to put the sweet potatoes through a ricer after they are cooked. This gets rid of all the fibrous part of the potato and makes for a much creamier dish than if you just use them whole.
Great tip, Janine!
Wow Lindsay, this looks amazing! I’m a huge fan of anything sweet on the diner table, especially when it’s a treasured family recipe. Those are always the best!
By the way, I don’t think I can get my hands on canned sweet potatoes. You know, because of the whole living in Europe thing… Do you think I can still make this with homemade sweet potato mash? Maybe add something extra or drain the puree or something to make them taste like the canned stuff?
Yes, I would just bake them instead of boiling (which was how I did it when I tried using fresh). The boiled ones held too much moisture and they didn’t really fluff up, but I think baked potatoes with the flesh scooped out and mashed would be great.
Going to try this for first time. Prefer not to use canned sweet potatoes. How
many sweet potatoes will I need to make 3 cups mashed. Knowing that Size of potatoes vary, would you be able help with this?….Please reply
