This silky sweet potato soufflé is made with baked sweet potatoes and warm spices for an easy to make side dish or dessert that’s perfect for fall.
I have no shortage of Thanksgiving side dish recipe ideas because let’s be honest, they’re the real Thanksgiving heroes. My mom’s classic stuffing, the best mashed potatoes, and my easy glazed carrots are the sides I make every year that keeps them coming back for more. This sweet potato soufflé is just one of them.
This sweet potato soufflé tastes more like a pumpkin or sweet potato pie minus the crust than the typical fluffy soufflé. Isn’t the filling everyone’s favorite anyway? It skips the fussiness of having to separate the eggs or whip any stiff peaks, and instead, everything is mixed in a food processor or blender at once, making it totally simple and quick to make.
Even more, you can choose which way to serve it, baked in one baking dish to serve out of for the table, or individual ramekins to dip into.
What’s in Sweet Potato Soufflé
This sweet potato soufflé is one of the very first recipes I made once I was in charge of Thanksgiving dinner. It’s also one of the very first I published here on the blog—a yam soufflé I adapted from Cooking Light Magazine (RIP) years ago. Over the years, I’ve changed the recipe quite a bit. Could I cut back on the butter a bit? I could. Use baked sweet potatoes instead of canned yams? Now we’re talking.
Here’s what you’ll need for this dish:
- Sweet potatoes—fresh is best. I used to make this with canned yams and while it was super yummy, I’ve since found using baked fresh sweet potatoes make a flavor difference.
- Butter—Be sure it’s softened so it mixes in well.
- Eggs—You can’t have a soufflé without eggs. These work as a binder for the sweet potatoes and give the soufflé its signature lift.
- Half and half—Adds a creamy richness. Use cream if you want something even richer, or whole milk if you want it to be a bit lighter.
- Light brown sugar—Dark brown sugar works here too, and provides a deeper flavor.
- Nutmeg—I prefer fresh nutmeg grated with my handy spice microplane, but ground will work.
- Cinnamon—Saigon cinnamon is a favorite.
- Cornstarch—it’s just a small amount, but don’t skip it, as it helps stabilize the soufflé.
How to Make Sweet Potato Soufflé
Bake the sweet potatoes. You can get my full rundown on baked sweet potatoes here, or here are the CliffsNotes version: Place the potatoes on a foil-lined baking sheet, whole with the skin on, and roast for 50 minutes to 1 hour (depending on the size), or until soft and the peels are papery and pulling away from the flesh. Cool until you can easily peel the jackets from the potatoes, then discard the peel.
Whip it good. Add all of the ingredients to a food processor or blender, and whip everything together until smooth (you can do this in batches if necessary).
Fill the baking dishes. This recipe can be made in lightly buttered individual ramekins or a 1-quart baking dish for your lovely dinner crowd. If you choose the ramekin route, fill them quite full. The soufflé does deflate quite a bit upon cooling.
How to Tell When the Soufflé Is Done
I heed these three signs that the soufflé is done baking:
- Puffed and domed, the top of the soufflé may have cracked just a bit.
- The soufflé has pulled away and separated from the edge of the baking dish.
- The center is springy to the touch.
The soufflé will deflate as it cools. Serve this dish warm, or at room temperature.
If serving at room temperature, this dish can be stored in the refrigerator for up to 3 days ahead of serving.
What’s the Difference Between Soufflé and Casserole?
The soufflé is an eye-catching, show-stopping dish. The wonderfully light and airy dish contains whipped eggs for lift and originated in France in the mid 17th century in more of a savory iteration, as an omelette soufflé. The sometimes sweet, sometimes savory dish endured a renaissance during the 1960s as an impressive dish for dinner guests. It’s basically timeless.
Casseroles are a different animal. While comforting and delicious, they’re more humble in their appearance and don’t usually don’t contain eggs unless they’re needed as a binder. Comforting and cozy, they’re almost always topped with a hearty sprinkling of cheese and sometimes bread crumbs, or even onion rings. Yeah, I went there.
How to Serve the Soufflé
Serve this soufflé warm or at room temperature with:
- Plain and all on its own
- Whip cream or crème fraîche, spiked with a bit of bourbon and vanilla
- Sprinkle with chopped walnuts or toasted pecans
- Vanilla bean ice cream is always a tasty topper no matter the dessert
- Bacon bits with a drizzle of caramel or maple syrup adds a savory touch
