Sweet Potato Soufflé Is The Perfect Thanksgiving Side Dish!

Today I’m sharing a classic holiday side dish recipe. Sweet Potato Soufflé is one of those recipes that you usually have once or twice a year for special occasions! I’m not quite sure why this is a reserved for Thanksgiving or Christmas, because it’s so easy, and everyone loves it!

I will say, no one ever actually GETS excited about this version of sweet potato casserole…until they have a bite. It’s always one of those dishes that you forget how delicious it is! Once I start eating this I can’t stop!

Is Sweet Potato Soufflé The Same As Sweet Potato Casserole?

Yes, and no…Sweet Potato Soufflé is a version of sweet potato casserole for sure, and they’re very, very similar. But here are the slight differences:

  1. Typically a sweet potato casserole is made without eggs and soufflé is made with eggs. A soufflé is also more dessert-like than a casserole.
  2. Another traditional characteristic, is that sweet potato casserole is usually is topped with marshmallows. And oh yummmm… I do love that version. But my soufflé has a buttery, crunchy pecan streusel on top and I could eat it with a spoon! It could be just what you grew up eating, but that streusel topping is out of control good!

Canned Sweet Potatoes Or Fresh Baked?

Either! You can easily use canned sweet potato puree OR you can baked sweet potatoes, let them cool and then mashed or blend them up until they’re very smooth. If you choose to bake them, you will need 2 – 3 medium sweet potatoes.

Can You Make Sweet Potato Soufflé Ahead?

Absolutely! This is a perfect make ahead dish. Remove it from the refrigerator about 15 minutes before baking to take the chill off, and then bake it according to the instructions in the recipe!

Also note that the longer this cools the more it will set up. Right out of the oven it will be looser, but still delish!

How To Store:

Just store this airtight in the refrigerator for up to 3 days. You could also freeze this for up to 30 days.

    I bought the canned sweet potatoes (yams) in the sugar syrup. Do I need to drain them before mashing them?
