Make this light and airy sweet potato souffle, a creamy and comforting side dish perfect for your Thanksgiving or Christmas table. This recipe uses simple steps to achieve a rich flavor and fluffy texture.

Ingredients

Scale
  • 2 cups mashed sweet potatoes (about 3 medium sweet potatoes)
  • 1 cup granulated sugar
  • 1/2 cup unsalted butter, melted
  • 3 large eggs, separated
  • 1/2 cup whole milk
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 1/4 cup all-purpose flour
  • 1/2 cup chopped pecans
  • 2 tablespoons brown sugar (for topping)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 1.5-quart casserole dish.
  2. In a large bowl, combine the mashed sweet potatoes, granulated sugar, melted butter, egg yolks, milk, vanilla extract, cinnamon, nutmeg, and salt. Mix until smooth.
  3. Whisk in the flour until just combined. Do not overmix.
  4. In a separate clean bowl, beat the egg whites until stiff peaks form.
  5. Gently fold one-third of the beaten egg whites into the sweet potato mixture to lighten it. Then, fold in the remaining egg whites until no white streaks remain. This keeps the souffle light and airy.
  6. Pour the mixture into the prepared casserole dish.
  7. For the topping, mix the chopped pecans and brown sugar in a small bowl. Sprinkle this mixture evenly over the top of the souffle batter.
  8. Bake for 35 to 40 minutes, or until the souffle is set in the center and lightly golden brown on top.
  9. Remove from the oven and let it rest for 5 minutes before serving.

Notes

  • You can use canned sweet potato puree if you prefer a quicker preparation for this holiday side dish.
  • For an alternative topping, substitute the pecan/brown sugar mix with marshmallows during the last 10 minutes of baking.
  • Ensure your egg whites are beaten in a grease-free bowl for the best volume.
