Why this Recipe Works
Nothing divides a country more than the choice of topping on your Sweet Potato Casserole.
Or maybe, I should say, nothing divides a family!
Do you like a crunchy pecan topping or a marshmallow topping on your sweet potato casserole? Do you love candied sweet potatoes?
I honestly love it both ways. Or without. Or even just baked sweet potatoes.
But today’s Sweet Potato Casserole is topped with the good stuff! Soft and sweet, pillowy marshmallow topping.
And y’all know I love me some marshmallows (Rice Krispie Treats are my favorite dessert)!
FYI. You could use this delicious Ruth’s Chris Sweet Potato Casserole recipe for the streusel topping and add marshmallows. No reason you can’t combine them BOTH!
Make a new tradition this year and serve up a big bowl of this tasty Sweet Potato Casserole with Marshmallows!
Step by Step Instructions
STEP 1. Start with cooked sweet potatoes.
STEP 2. Add brown sugar, salt, vanilla, eggs, and melted butter.
STEP 3. I like to use an electric mixer on low speed to mash them, but you could use a hand masher for a rustic texture, or a food processor for a smoother texture.
If you beat them with the mixer, they will get a fluffier texture, so you decide what you prefer!
STEP 4. Transfer filling to a greased 2 qt baking dish.
STEP 5. Bake in a 350 degree F oven for 30 minutes. Remove from oven and sprinkle mini marshmallows on top. Or use our homemade marshmallows for a rich finish.
STEP 6. Return to oven for 10 minutes, or until lightly browned.
How to Cook Sweet Potatoes
I prefer to bake them whole in the oven, then scoop out the soft sweet potato center. No peeling.
To do this, wash potatoes and poke with a fork. Place unpeeled sweet potatoes on baking sheet and bake in a 400 degree F oven for about an hour (place a piece of aluminum foil on the baking sheet for easy clean up)!
Once done, slice in half and scoop out center.
You could also boil the sweet potatoes. While this is a faster option, it’s more hands on. Don’t forget, for the boil option you’ll need to peel the potatoes first!
You can also cook your sweet potatoes in the Instant Pot!
Recipe FAQs
Sweet Potato Casserole recipe can be prepared up to 48 hours in advance by cooking and mashing the sweet potatoes and assembling the casserole as directed. Refrigerate until ready to bake before the meal.
Absolutely. Leave them off entirely and you can still enjoy sweet potato casserole without marshmallows.
Dark brown and light brown sugar can be used interchangably in sweet potato casserole. I usually only have light brown sugar on hand.
More Thanksgiving Side Dishes
This is the best sweet potato casserole recipe, but there are plenty of other sides that grace our holiday table.
- Cheesy Hashbrown Casserole is a must have any holiday. I’m a big fan of the crunchy corn flake topping.
- Of course, Green Bean Casserole with those crispy fried onions on top are a winner. Do you see a pattern with crunchy toppings?
- Well, while we’re at it can we discuss this Ritz Mac and Cheese? So creamy, but baked to perfection (and again with a crunchy, buttery topping).

I made this recipe but cut it in half and it was delicious. If I made the full recipe but put it in two 8×8 dishes would I cut the baking time?
I cut this recipe in half and it was delicious. Could I do the full recipe but split it into two 8×8 dishes? If so, would I bake at normal time or would I have to cut time back?
So I didn’t realize I had to cook it for 30 minutes before putting the marshmallows.. so I put the marshmallows on, can I still cook it for 30 minutes without burning the marshmallows?
The marshmallows will definitely burn. I would remove them before cooking.
This has been our go to family sweet potato casserole for the hoildays for years. it is amazing. The kids love it and ask for it. We use coconut sugar instead of brown sugar. Thank you for a great recipe
Absolutely delicious! Perfect amount of all the ingredients. Not too sweet. This will definitely be a keeper!
This was wonderful and easy to follow directions. I used the canned yams. We will have this again. 😊
Followed direction to the “T”. Didn’t add anything…..Turned out Fantastic!
Thanks
Happy to hear it 🙂
This was good. I used your idea of baking the potatoes. Instead of the orange fleshed ended up with sweet yellow potatoes which worked fine. Melted the butter with walnut oil for nuttier flave, with pinch of salt, and brown sugar, just chopped cooked taters with a fork, tossed with the butter mixture, topped with the marshmallows, baked, etc. was plenty sweet and left out the eggs and vanilla (IMO much better without).
Can you use BRUCE’S YAMS, instead of the SWEET POTATOES???😉
Yes, I did a combination of a 40 oz. can of Bruce’s and a couple of nice sized raw sweet potatoes. You absolutely do not need to peel the potatoes before you boil them because the peel slips off very easily once you cool them down with cold water. Put them together in a big bowl and mash away! I use cinnamon, nutmeg, allspice and a touch of ginger along with melted butter and brown sugar (I only had dark) which was fine! I also broke up about a cup of pecans with my fingers and added to the mixture. I cooked this for about 45 minutes on 350 degrees then took it out of the oven and covered the whole top with the big ‘s’mores (square) marshmallows and put it back in the oven for about 15 more minutes for them to become golden brown! They were absolutely delicious!!!
If I’m using a 9×13 pan should I cook it for 20 min?
