How to Make Sweet Potato Soufflé (Step-by-Step)
Time needed: 1 hour and 5 minutes
- Preheat the Oven
Preheat the oven to 350°F and grease a 9×9-inch baking dish with butter.
- Cook and Peel Sweet Potatoes
Wash and cook sweet potatoes using your preferred method:
Stovetop method: Bring large pot of water to boil, add whole sweet potatoes, cook 20-30 minutes until fork-tender
Instant Pot method: Add sweet potatoes with water to cover, high pressure 10 minutes, quick release
Oven method: Poke with fork, bake at 400°F for 45-60 minutes until soft
Cool and peel the sweet potatoes once tender. Let cool slightly before handling. - Mix the Sweet Potatoes
Mash sweet potatoes in large mixing bowl until completely smooth and silky. No lumps!

- Add the Wet Ingredients
Add wet ingredients: Whisk in eggs, heavy cream, brown sugar, softened butter, vanilla, and salt.
Beat until fluffy: Use hand mixer or stand mixer to beat mixture until light and airy, about 3-4 minutes.
- Prepare the Topping
Make cinnamon crumb topping: In separate bowl, combine flour, brown sugar, and cinnamon. Cut in softened butter with fork or pastry cutter until mixture forms small crumbs.
- Assemble the Soufflé
Assemble soufflé: Pour sweet potato mixture into prepared baking dish, spreading evenly. Sprinkle crumb topping over entire surface.

- Bake
Bake the sweet potato soufflé for 45 – 50 minutes.
The soufflé is ready when the top is golden brown, and a fork inserted into the center comes out clean.
Pro Tips for Perfect Sweet Potato Soufflé
- Room temperature eggs incorporate better for maximum fluffiness
- Don’t skip the beating step – this creates the light, airy texture
- Make ahead tip: Prepare through step 8, cover and refrigerate up to 24 hours. Add 10 minutes to baking time if cold.
Storage and Reheating
- Refrigerate leftovers up to 3 days
- Reheat in 350°F oven for 15-20 minutes until warmed through
- Freezing: Not recommended as texture will change
Why Choose Soufflé Over Casserole?
Traditional sweet potato casserole gets “a pumpkin pie-like treatment, with brown sugar and vanilla for a deep caramel flavor and butter and eggs for richness”, but this soufflé takes it one step further with a lighter, more elegant texture that’s perfect for special occasions.
