Plus, you are going to sound ultra-impressive when you casually mention that you are bringing a souffle.

Though the word “souffle” suggests a dish that’s fussy (and you can allow your friends to assume as much), sweet potato souffle is EASY.

Souffle vs. Casserole

Unlike a classic French souffle, southern sweet potato souffle requires zero meticulous whipping and folding of egg whites or hovering by the oven as it bakes to pray to the food gods that it won’t fall.

  • The process to make sweet potato souffle is more like making a casserole: prepare filling, add delicious topping, then bake.
  • The primary difference between a casserole and souffle is the texture of the sweet potatoes. Because eggs are beaten with the sweet potatoes in a sweet potato souffle, they become fluffy and light, just like a classic souffle.

Sweet potato souffle is also much more affordable to make than its fancy name indicates, especially if you pick up your groceries at ALDI.

I’ve been shopping at ALDI since Ben was in graduate school and we were on a serious budget. I am excited to be partnering with them to create this recipe today, because I firmly believe that you shouldn’t have to sacrifice eating well just because you don’t have unlimited money to spend on groceries.

ALDI offers fantastic value and quality for its products, an attribute I especially appreciate this time of year.

The holidays are special, but between presents, entertaining, and giving to good causes, the numbers add up.

Making a change as simple as picking up your groceries at ALDI can go a long way towards stretching your dollar, without having to give up the good eats that make the holidays so special. (In fact, ALDI is proud that customers can get everything they need for a traditional Thanksgiving meal, including the turkey, sides, and pumpkin pie, all from ALDI and all for less than $30.*!)

The Sweet Potato Bake Debate

One of the great battles of our time (not to be dramatic or anything) is whether or not Thanksgiving sweet potatoes should include marshmallows.

  • I am a hard NO, preferring instead a more savory take like these Glazed Sweet Potatoes.
  • My sister Elizabeth? She loves the marshmallow version so much, she could practically eat it for breakfast.

This recipe for sweet potato souffle is the ideal middle ground.

It’s sweeter than the Brown Butter Mashed Sweet Potatoes in my cookbook and my Healthy Sweet Potato Casserole, but nowhere near as cloying as the marshmallow variety.

How to Make Sweet Potato Souffle

Fluffy sweet potato souffle is Southern by origin and remains popular at Thanksgiving throughout the South.

Traditionally it is VERY sweet; most of the recipes I found contain more sugar than Sweet Potato Pie.

  • I found I could cut down on the sugar significantly, especially if I roasted the sweet potatoes instead of steaming or boiling them.
  • Roasting concentrates the sweet potatoes’ natural sugars, making the souffle taste sweeter.

Roasting works with what this delicious, healthy vegetable gives us naturally, instead of covering it up with more sugar than a dessert.

The Ingredients

  • Sweet Potatoes. My fave holiday side! I picked these orange beauties up at ALDI, along with the rest of my regular produce for the week. Sweet potatoes are packed with fiber, vitamins, and antioxidants.

Sweet Potatoes vs. Yams

While often confused for one another (and sometimes labeled incorrectly), sweet potatoes and yams are not the same.

  • The sweet potatoes most typically available in North America are large with orange flesh and smooth skin.
  • Yams have a brown, tough, bumpy skin similar to bark and are the size of small potatoes.
  • The texture of yam flesh tends to be more starchy and dry than a sweet potato.
  • Yams are not readily available in North America. Chances are what you are seeing at the store is a sweet potato. Carry on!
  • Eggs. The key to the fluffy sweet potato souffle’s airy texture. I prefer to purchase organic, as I notice a distinct difference in the quality and taste. Organic doesn’t have to break the bank—I used Simple Nature Organic Cage Free Brown Eggs from ALDI.
Ingredients for sweet potato souffle
  • Pecans. Nuts are another ingredient that can be pricey, which is why I pick up a bag of Southern Grove Pecan Halves on almost every ALDI trip (they are also an excellent excuse to bake Pecan Pie Bars). 

Market Swap

  • For sweet potato souffle with walnuts, swap the pecan halves in the topping for walnut halves.
  • If you prefer a sweet potato souffle without nuts, you can omit them.
  • Butter. Butter adds rich, necessary holiday flavor to both the sweet potatoes and the pecan topping.
  • Milk. Helps make the sweet potato mixture extra creamy. I used 1% milk, but you can use any milk you have on hand.
  • Sugar + Maple Syrup. I tried to keep this sweet potato souffle healthy relative to most by cutting down on the amount of sugar used compared to many traditional recipes. Instead of using only refined sugar, I opted to add in a little maple syrup for natural sweetness. It’s also a divine pairing with sweet potatoes and pecans.
  • Vanilla. Adds a warmth and coziness. Vanilla is surprisingly wonderful in sweet potato bakes.
  • Cinnamon. Cinnamon and sweet potatoes are a dream team.
  • Flaked Coconut. While optional, I love the touch of extra nuttiness it adds to the topping. The flavor is not strong, so even if you are not typically a coconut fan, you will likely enjoy it here.

Frequently Asked Questions

Can I Use Canned Yams to Make Sweet Potato Souffle?

Yes, but do so with caution. Because canned yams (or canned sweet potatoes) come pre-sweetened, I recommend leaving out most of the sugar and maple syrup from the filling to start. Once it’s mixed, you can taste it and adjust if you’d like your filling sweeter (remember, the topping is sweet too).

What Can I Use Instead of Maple Syrup?

If you don’t have any maple syrup on hand, you can swap it for honey.

Can I Microwave the Sweet Potatoes Instead?

Baking the sweet potatoes adds wonderful, important flavor to this dish, so I highly recommend taking the time to do this step. However, if you’re crunched for time, you can microwave the sweet potatoes. Pierce each potato 3 to 4 times with a fork, then microwave them for about 5 minutes.

  • 5 large or 6 medium sweet potatoes about 7 cups once mashed
  • 6 tablespoons Countryside Creamery Unsalted Butter melted or at room temperature
  • 2 large Simple Nature Organic Cage Free Brown Eggs
  • 1/4 cup Baker’s Corner Granulated Sugar
  • 1/4 cup Specially Selected Pure Maple Syrup
  • 1 tablespoon pure vanilla extract
  • 1/2 teaspoon Stonemill Ground Cinnamon increase to 1 teaspoon if you LOVE cinnamon
  • 1/2 teaspoon kosher salt
  • 1/4 cup milk I used 1%


  • 1/4 cup Countryside Creamery Unsalted Butter
  • 1 1/4 cups Southern Grove Pecan Halves finely chopped
  • ¼ cup flaked coconut optional; I used unsweetened; sweetened will work too.
  • 1/2 cup Baker’s Corner Brown Sugar packed
  • 1/3 cup Baker’s Corner All-Purpose Flour
  • ¼ teaspoon kosher salt

  • Bake the sweet potatoes: Preheat the oven to 425 degrees F. Line a rimmed bakingsheet with aluminum foil or parchment paper. With a fork, poke holes in the outsides of the sweet potatoes. Bake for 40 to 60 minutes (timing will depend upon the size of your sweet potatoes), until very tender when pierced with a fork. Set aside to cool.

  • Prepare the souffle: Reduce the oven temperature to 350 degrees F. Coat a 9×13 casserole dish or similar 2 ½ quart casserole dish with nonstick spray.

  • Once the sweet potatoes are cool enough to handle, slip off the peels. Scoop out the flesh and place in a large mixing bowl or the bowl of a standing mixer fitted with the paddle attachment.

  • Add the butter, eggs, sugar, maple syrup, vanilla, cinnamon, salt, and milk.

  • Beat until smoothly combined.

  • Scoop into the prepared baking dish.

  • Prepare the topping: In a medium mixing bowl, melt the butter. Sprinkle the nuts, coconut, brown sugar, flour, and salt over the top. Stir until evenly moistened and combined. Scatter the mixture over the sweet potatoes in an even layer.

  • Bake the sweet potato souffle until the topping is lightly browned and your kitchen smells amazing, about 40 minutes. Let rest 5 minutes, then enjoy warm.

  • TO STORE: Refrigerate souffle in an airtight storage container for up to 4 days. 
  • TO REHEAT: Rewarm leftovers in a baking dish in the oven at 350 degrees F or in the microwave. 
  • TO FREEZE: Freeze souffle in an airtight freezer-safe storage container for up to 3 months. Let thaw overnight in the refrigerator before reheating.
