Sweet potato casserole is a staple at most Thanksgiving tables. Add some marshmallow creme and it’s closer to a yummy dessert.Jump to Recipe
Every Thanksgiving my grandpa is in charge of the sweet potato casserole. We call it a side dish, but really it’s more like a dessert. Yes, it’s sweet potatoes, but we top it with marshmallow creme and brown sugar. So it’s a bit of your starch/veggies and dessert.
Of course, if you don’t want the marshmallow creme, you can skip that. Then you would basically be making candied yams. In my opinion, though, the marshmallow is what makes this so delicious.
Most of the time, grandpa put the marshmallow creme on top as-is. When I make it, I like to put it under the broiler to brown the marshmallow on the sweet potatoes just a bit.
Grandpa’s Sweet Potato Casserole Step by Step
- 4 tbsp butter, softened
- 4 large sweet potatoes, peeled and sliced
- 1 cup brown sugar
- 1 jar marshmallow creme
Preheat the oven to 350F.
In a 9×13 baking dish, spread out 2 tbsp of butter.
Spread the potatoes on top of the butter.
Add the brown sugar, then top with the remaining butter.
Bake for 1 hour.
Top with marshmallow creme while still warm.
Place under the broiler for a few minutes to brown the marshmallow creme, if desired.
Grandpa’s Sweet Potato Casserole Leftovers
Any leftover sweet potato casserole can be stored in an airtight container in the refrigerator for up to 2-3 days. We like to reheat it in the oven so they don’t get soggy.

Mmmm this sounds yummy! I haven’t had a sweet potato casserole but you piqued my interest with your recipe. I can’t wait to make this! Perfect for the upcoming season and even Thanksgiving.
What a great idea for a casserole. I’ve had scalloped potatoes before, but never with sweet potatoes.
Good tip to reheat in the oven so it doesn’t get soggy. That marshmallow topping is everything.
We are a family of sweet potato lovers, so this is right up our street and a must try one weekend, because it looks yummy xx
This recipe is really interesting. The combination of sweet potato and marshmallow creme will definitely challenge my pallet.
Wow! Just a few ingredients and a lazy bum like me can also experiment with this recipe. Btw sweet potato is so versatile and i like it’s mild aroma.
Now, this is one I really need to try! I love sweet potato casserole and haven’t had it in years!
This is yummy, I love when my mom cooks casseroles before but never tried this one. I will add it to the list.
That’s certainly something I’ve never tried. What an unusual combination although I can really see that working well. I need to try this next time I have guests and see what they think.
This goes great as a dessert!
You’re Grampa is awesome! He knows how to make a sweet potato casserole. I love that it is gluten-free and I would put about 6 inches of marshmallow cream on top!
Hhhhmmmm….I think I will love this casserole with my cup of tea in the evening. Sweet potato has always been a good friend of mine.
Sweet potatoes are widely available in my locality. Plus i love a good casserole. But dessert casserole is new to me. Will surely try this recipe.
I’m in love with this recipe. The huge dollops of marshmallow fluff really make it for me!
I’m getting hungry just looking at this! I LOVE this spin on a classic. I can’t wait to make it.
This sweet potato casserole dish is new to me. It is so full of health. Plain boiled sweet potatoes are not a hit with my kids, but this will surely be.
This looks so so good!!! I can’t wait to make your grandpas’ recipe, can’t wait!!!! I love sweet potatoes.
I love sweet potato casserole, but we always mash our potatoes! This sounds like a texturally interesting version.
I really love sweet potatoes, but would have never thought to put marshmallow creme on top of them.
