What Goes Into Fluffy Sweet Potato Souffle?

Looking for something different from your typical sweet potato casserole? Make sweet potato souffle! This delicious American side dish can even be served as a dessert for a special occasion.

It’s so simple to make too, taking only 10 minutes of prep time. You’ll take cooked, mashed sweet potatoes and mix them with softened butter, white sugar, vanilla extract, milk, and beaten eggs for the base.

Then you’ll make the streusel topping with melted butter, brown sugar, flour, flaked coconut, and chopped nuts and put it over the top. Bake it up and enjoy the tantalizing aroma until it’s time to eat. It’s absolutely divine and will disappear faster than you can say, “Sweet potato souffle!”

Common Questions

Can I omit the nuts in the streusel topping for sweet potato souffle?

Absolutely! Whether you have a nut allergy or just a disdain for all things nuts, you can leave them out. And if you like nuts, you can use pecans, walnuts, or even almonds (or combine them) as long as you chop them for a better texture.

Can sweet potato souffle be frozen?

Yes, you can freeze sweet potato souffle. However, you should only make the body of the souffle first and make the streusel topping fresh when you’re ready to bake it. It will be good in your freezer for up to 1 month.

What's the difference between souffle and casserole?

While this isn’t the typical French-style souffle, it is still a souffle because it is made with eggs. The eggs make it have a soft and light texture which means you can serve it as a side or a dessert as you see fit. Meanwhile, a casserole is more of a medley of ingredients that are baked.

Chopnotch Tips

  • You can use canned yams to save time, though this recipe will taste far better if you use fresh sweet potatoes and take the time to cook and mash them first.
  • This recipe merely specifies chopped nuts for the streusel, leaving the nuts up to you. You can omit them if you’d prefer or use pecans, almonds, or walnuts to make your chopped nut mix.
  • The all-purpose flour in this recipe can be swapped for a gluten-free variety. Use one with a 1:1 ratio that includes a binding agent to ensure the texture stays as it should.
