Sweet potatoes are a wonderful way to switch up your starchy carbs, and one of the best parts? They can be served sweet or savory! I’m a huge fan: I love them in this crockpot sweet potato turkey chili just as much as in these sweet potato pancakes.

Why You’ll Love This Recipe

Contrary to popular belief, soufflé isn’t as hard to pull off as you may think. I discovered just that the first time I made this Sweet Potato Soufflé. I was blown away by the richness and simplicity of the dish.

Much of the sweet flavor comes from the crunchy and crispy topping. It’s made with brown sugar, chopped pecans, and cinnamon: all things I adore. It’s an update on typical sweet potato side dishes that are made with marshmallows.

I’ve been looking for a fun new way to serve up one of my favorite vegetables and I found it in this sweet potato soufflé with pecans! If you plan on serving this for Thanksgiving it pairs well with the Cheesy Zucchini Casserole too.

Ingredients

Ingredients Needed

  • Sweet Potatoes: You’re going to need to peel and cube the sweet potatoes for your soufflé. You could also use pre-cut frozen varieties to save a little time.
  • Brown Sugar: Use it in the potato soufflé filling as well as in the crunchy pecan topping. It boasts a toffee and molasses flavor you just don’t get when you only use regular white sugar.
  • Cinnamon: Again, you’ll need it for the filling and the topping! This warm and earthy spice pairs wonderfully with the other ingredients.
  • Pecans: Chopped pecans paired with cinnamon and brown sugar are what dreams are made of. Or, in this case, the topping for your potato soufflé!

Step-by-StepRecipe prep.

Preheat your oven to 425°F and grease a 9×13-inch baking dish with your favorite cooking spray, or simply a bit of oil.

  1. Pre-cook the sweet potatoes. Place your peeled and cubed potatoes into a large pot and cover with water. Bring to a boil and continue to cook over high heat for 15-20 minutes, or until the potatoes are fork tender.
  2. Mash. Remove the sweet potatoes from heat and drain. Place them into a large bowl and, using a handheld mixer, beat them until they become smooth.

Storage and or Freezing Instructions

  • Make-ahead instructions: You can prepare the soufflé filling and crunchy pecan topping up to 24 hours before baking. Store them both (separately) in airtight containers in the refrigerator.
  • Freezing instructions: Prepare and bake this sweet potato soufflé with pecans as instructed and allow it to cool. I recommend that you bake it in a freezer-safe aluminum baking dish. Cover tightly with tin foil, then store it in your freezer for up to 3 months.
  • Storage instructions: Store any leftovers in an airtight container in the fridge where they will keep for up to 4 days. To reheat, you can use your microwave or your oven.

Recipe Notes and Tips

  • Roast the sweet potatoes. For even more added flavor, you should consider roasting the sweet potatoes instead of boiling them. Roasting will bring out their natural sweetness.
  • Use canned yams. While I typically prefer using fresh over frozen or canned, you can use canned yams instead of sweet potatoes for this recipe. You may want to adjust the sugar quantities, however. Yams from a can usually come in syrup.

FAQS

What is the difference between casserole and soufflé?

The biggest difference between casserole and soufflé is the texture. Soufflé tends to be fluffier and lighter. That’s why I like to use a hand mixer to essentially whip the sweet potato filling for this soufflé recipe.

How do you thicken sweet potato soufflé?

Don’t underestimate the power of eggs in this dish! It’s a binder that thickens and stiffens the filling for this dish.
