We have been making this exact Sweet Potato Casserole recipe for as long as I can remember. Over the years, I have tried many different recipes and this one is by far the best version I have ever tasted.
I think it all comes down to that secret ingredient my Mom adds. It comes in a can and is extra creamy. Any guesses what it is?!
Secret Ingredient for the best Sweet Potato Casserole Recipe
Why, it’s sweetened condensed milk of course!
If you have been around here long enough, you know how much my Mom likes to sneak that sweet nectar into recipes.
Just like in the now famous Mama’s Best Banana Pudding, the sweetened condensed milk adds the perfect sweetness and creaminess to this Sweet Potato Casserole.
I have tried making this casserole recipe many other ways…like with milk, cream and even evaporated milk.
I have also tried regular sugar, brown sugar and maple syrup to sweeten this casserole, but I always come back to using sweetened condensed milk!
Sweet Potato Casserole Ingredients
Other than our secret ingredient of sweetened condensed milk, this Sweet Potato Casserole recipe is very classic and southern. 😉
All you will need for this Sweet Potato Casserole with Marshmallows:
- fresh sweet potatoes
- butter
- sweetened condensed milk
- cinnamon
- nutmeg
- salt
- marshmallows
Some people add eggs to their Sweet Potato Casserole and for the life of me I can not figure out why.
To me, when you add eggs, the final product turns out more like a soufflé. It’s just not that classic Thanksgiving casserole that I am personally searching the Thanksgiving table for.
It’s not the way we made it growing up and I prefer the denser texture of perfectly seasoned and mashed sweet potatoes instead!
How to make Sweet Potato Casserole?
The first step to making our Sweet Potato Casserole is to boil our peeled and cubed sweet potatoes in water on the stove until fork tender.
Then we add the melted butter, sweetened condensed milk, cinnamon, nutmeg and salt. Mash away until smooth and transfer the sweet potato mixture into a greased 9×13 casserole dish.
The final step is to load on all those marshmallows on top of the sweet potato casserole.
I like to use large marshmallows — just look at that glorious marshmallow to sweet potato ratio — but you can use minis if you prefer.
Then we bake the casserole at 350°F for a few minutes to make sure everything is hot and to let the marshmallows on top get perfectly toasted.
Make ahead Sweet Potato Casserole
If you want to make this casserole ahead of time, follow all steps but stop right before you put the marshmallows on top.
At this point, cover the casserole dish tightly with a lid, cling warp or foil. Then keep it refrigerated until you are getting close to being ready to serve it.
When you are ready to serve it, take it out of the fridge and let it warm up a little on the counter.
Heat the casserole in oven for 15 minutes (still covered with foil), then remove from oven and carefully top with marshmallows. Then bake it a little longer, uncovered, just until the marshmallows have toasted on top!
This casserole can also sit on the counter for a few hours and wait for your other Thanksgiving side dishes to be ready. Then they can all go into the oven together when you are getting close to eating.
I also included the full make ahead steps and directions in the Sweet Potato Casserole recipe below as well!

do you think I could use drained canned sweet potato?
Hi Jennie! I wouldn’t recommend it. Canned sweet potatoes have soaked up a lot of sweetness and moisture from the syrup. So you would have to cut back on a lot of the liquid ingredients to get a decent texture and I can’t guarantee how your final recipe would taste.
Using canned is fine, drain well though. My mom also adds an egg to hers and chopped pecans to help with the texture too. I think she uses two big cans of yams and one small can of sweetened condensed milk and one egg. You may omit the butter though or take it down a smidge.
This is the perfect side dish for Thanksgiving! Love all those fluffy marshmallows!
Have a Friendsgiving at work tomorrow. Saw this and ran out and got everything to make it. Stuck a little extra in a little oven crock I had so I could try it before I take it in to work tomorrow. DELICIOUS. So excited now to take this in tomorrow for everyone and it was very easy to make. Thanks!

This looks delicious! I can’t wait to make it. Silly question but I want to be sure; am I buying sweet potatoes or yams? Does it matter? The picture just looks so orange and sweet potatoes to me are whiter? Thank you so much for your help! 🙂
Hi Jessica,
Do you put brown sugar in this recipe? I know it’s not on the ingredient list, but this is my first time making this kind of casserole. Lol
