Sweet Potato Vanilla Bean Soufflé

Ingredients

- 3 medium sweet potatoes
- 1 vanilla bean
- 4 tablespoons unsalted butter
- 1/2 cup heavy cream
- 1/4 cup whole milk
- 3 large egg whites
- 1/4 teaspoon cream of tartar
- 1/4 cup granulated sugar
- 1/2 teaspoon vanilla extract
- 2 tablespoons brown sugar

Instructions

1. Preheat and Prepare
Preheat your oven to 375°F (190°C). Grease a 9-inch soufflé dish generously with butter.

2. Cook and Mash Sweet Potatoes
Pierce the sweet potatoes with a fork several times and place them on a baking sheet. Roast in the oven for about PT1H until tender (1 hour). Remove from the oven and let cool slightly. Once cool enough to handle, peel the skins off and mash the sweet potatoes until smooth.

3. Infuse Vanilla
Split the vanilla bean lengthwise and scrape out the seeds with a knife. In a small saucepan over low heat, melt 4 tablespoons of butter with the vanilla seeds and pod. Let it cook for about PT5M (5 minutes) to infuse the flavors. Remove from heat, discard the pod, and set aside.

4. Prepare Sweet Potato Mixture
In a large bowl, combine the mashed sweet potatoes with the infused butter, heavy cream, whole milk, and vanilla extract. Mix until well incorporated and smooth.

5. Beat Egg Whites
In a separate clean, dry bowl, beat the egg whites with the cream of tartar until soft peaks form. Gradually add granulated sugar, beating until stiff peaks are achieved.

6. Fold and Combine
Gently fold the beaten egg whites into the sweet potato mixture until well combined. Be careful not to deflate the egg whites.

7. Assemble and Bake
Pour the mixture into the prepared soufflé dish. Sprinkle the top with brown sugar to create a caramelized topping as it bakes. Place the soufflé dish in the oven and bake for about PT30M (30 minutes) until puffed and golden.

8. Serve Immediately
Remove from the oven and serve immediately to ensure the soufflé’s light and airy texture is maintained.
