How to Make Sweet Potato Soufflé

Step-by-Step Instructions

Prepare the Sweet Potatoes: Preheat the oven to 375°F. Wash the sweet potatoes, pierce them with a fork, and bake on a foil-lined baking sheet for 45-60 minutes, or until soft. Allow to cool, then remove the sweet potato flesh.
Mix the Ingredients: In a medium bowl, combine the sweet potato flesh, brown sugar, granulated sugar, melted butter, heavy cream, eggs, vanilla extract, cinnamon, and salt. Use a food processor or electric hand mixer to blend until smooth.
Prepare the Baking Dish: Grease a 2-quart soufflé dish with melted butter or nonstick spray. Pour the sweet potato mixture into the prepared baking dish.
Add Toppings: For a pecan crumble, mix pecans, brown sugar, flour, and butter, then sprinkle over the sweet potato mixture. Alternatively, top with mini marshmallows.
Bake: Place the dish in a preheated oven and bake at 350°F for 30-35 minutes, or until the top is golden brown and the center is set.

Tips for Achieving Fluffiness

Avoid overmixing: Overmixing can lead to a dense texture instead of the desired fluffiness.
Incorporate air: Beat the eggs separately before folding them into the sweet potato mixture for an extra-light texture.
Use a preheated oven: Ensures the soufflé rises properly without collapsing.

Sweet Potato Soufflé vs. Casserole

Cooking Techniques
