Sweet Potato Souffle is a delicious, rich, and creamy side dish. Topped with crunchy, oven-roasted pecans and a sprinkle of cinnamon sugar.

Thanksgiving side dishes are probably my favorite part of the holiday, with all the desserts as well. I always make this Sweet Potato Casserole, cheesy Creamed Corn, creamy and fluffy Mashed Potatoes, and some simple Sweet Potatoes on the side.

I never skip dessert, and these Pumpkin Cheesecake Bars are on top of my list, with this amazing Pecan Pie Cheesecake. If you can’t decide which one to make, settle for this Pecan Pie Pumpkin Cheesecake, it combines the best of both worlds.

Best Sweet Potato Souffle recipe

Sweet Potato Soufflé is such a tasty and somewhat different side dish that you can make for the holidays. I love that it is something between a sweet potato casserole and a sweet potato pie. I absolutely adore the tender texture, especially when combined with a cinnamon sugar topping and crunchy pecans.

If you are looking to elevate your holiday game, but still stay within the traditional recipes borders, this Sweet Potato Souffle is a great choice. I mean, it sounds fancy, while it’s very easy to make. You can get creative with the toppings and add some marshmallows or keep it simple and just top it with pecans or walnuts.

What is Sweet Potato Souffle?

Sweet Potato Souffle is a Souther dish made with sweet potatoes, sugar, cream, eggs, butter, and self-rising flour. It is very similar to Sweet Potato Casserole, with a slightly different and smoother texture.

Is Sweet Potato Souffle a dessert?

That is the question that I get most. The short answer is that you choose what it is. Sweet Potato Casserole and Sweet Potato Souffle can be considered both, a dessert and a side dish. It all comes down to your own preference and also what ingredients you used, how sweet you prepared the dish. But, they both can be enjoyed as a side dish, which is a great excuse, as they are on the sweeter side.

How long do you bake Sweet Potato Souffle?

Sweet Potato Souffle is usually baked at 350 degrees F for about 1 hour or until puffed. Because every oven is different, I recommend checking on it after about the 50-minute mark. 

What is the difference between sweet potato souffle and casserole?

The difference is not huge, however, in my opinion, these are the main factors that make them different:

  • Texture:

Sweet Potato Souffle is supposed to be much puffed, tender and smoother, also hold its shape better. Usually, for the souffle, to get a very smooth texture, the ingredients are added to a blender and processed until smooth and well combined. A hand mixer can be used as well. While sweet potatoes for the casserole are just mashed.

  • Key Ingredient:

A key ingredient in Sweet Potato Souffle that is usually missing in sweet potato casserole is Self Rising Flour. The flour is added to add that airy, puffed texture to the souffle, and bring all the ingredients together, making it easier to scoop or even cut.

  • Toppings:

While Sweet Potato Casseroles are known for all the topping options, when it comes to souffles, they are kept simpler, because the selling point is really the texture. However, this doesn’t mean that you can’t improvise and add your favorite toppings.

How to make Homemade Self Rising Flour?

This recipe asks for a small amount of self-rising flour, and I know that many don’t keep it on hand. If you don’t want to buy an entire bag, here is how you can make your own very quickly at home.


  • 1 cup all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon salt


In a small bowl, whisk all the ingredients until fully combined. Store or use in recipes.

Can I make Sweet Potato Souffle in advance?

Yes, you can. You can assemble it 24 hours in advance, wrap tightly in plastic wrap, and bake when ready. Also, you can bake it, let it fully cool, wrap tightly in plastic wrap, and refrigerate it. Cover with foil and warm it up in the oven before serving.

How to store Sweet Potato Soufflé?

Refrigerate the souffle in shallow airtight containers or resealable plastic bags, if kept in the baking dish, cover tightly with plastic food wrap. Properly stored, it will last for 3 to 5 days in the refrigerator.


  • First, assemble the souffle and make sure it’s not warm.
  • Skip the pecan and cinnamon sugar topping, those can be added right before baking.
  • Lay a sheet of plastic wrap or aluminum foil directly on top of the souffle in the dish, then wrap tightly and in many layers over the top rim and around the baking dish or the container.
  • Freeze for up to 3 months for best results.
  • Thaw overnight before baking.


  • First, cool souffle to room temperature.
  • After that, lay a sheet of plastic wrap or aluminum foil directly on top of the souffle in the dish, then wrap tightly and in many layers over the top rim and around the baking dish or the container.
  • Also, individual servings or leftovers can be added to freezer-safe ziplock bags.
  • Freeze for up to 3 months for best results.
  • Thaw overnight before heating up in the oven or the microwave.

Hello! For making the self rising flour, you have an alternative to making it but you use a whole cup, where the recipe only calls for using half a cup. I am confused. What amount should I be using?


You have to use only half a cup, save the other half for other recipes.



Hi! Whatā€™s the best way to make this dairy free?


Use any vegan butter and milk that you like, it will work very well. I usually recommended coconut milk from a can as it is creamier.



If all I have is dark brown sugar, will that alter the recipe to much? What will it do?


That will work fine



I made this recipe last year and it was amazing ... everyone went back for seconds. I'm making it today per requests!! Thank you so much for this recipe ... it's now a tradition for our Thanksgiving meal! Happy Thanksgiving!!



November 28, 2020 This recipe was sensational. I added a few other ingredients that really made the souffle pop. I didn't prefer the nuts, but did add a little cinnamon and nutmeg to the batter. Right before baking I topped it with brown sugar. Delicious.

If I double the recipe do I add to baking time


You may have to add 20 minutes or so.



I made this recipe dairy free using vegan butter and almond milk. I found the extra 3 tablespoons of melted butter that are drizzled over the souffle just before baking were way too much. It resulted in a bit of a puddle of butter situation after baking, and I had to bake it for longer. It still tasted delicious but they weren't necessary. Anyone else have this issue?
