Instructions

Make the sweet potato purée

  • Preheat the oven to 400°F (200°C). Butter a 2 1/2-quart baking dish.
  • Bake the sweet potatoes on a foil-covered baking sheet for 1 hour, or until they're soft throughout. Let stand until cool enough to handle.
  • Slip the peels from the potatoes, discarding the peels. Place the sweet potatoes in a large bowl or the bowl of a stand mixer and mash until very smooth. Add the eggs, sugar, butter, vanilla, milk, cinnamon, nutmeg, and salt and mix with a stand mixer or handheld electric mixer until smooth. Scrape the sweet potato mixture into the baking dish.

Make the pecan streusel

  • In a medium, bowl, stir together the pecans, brown sugar, flour, and butter until thoroughly combined.

Make the sweet potato soufflé

  • Spoon the streusel over the sweet potato mixture, smoothing it evenly. Bake the soufflé until the surface is golden brown, about 30 minutes. Let it rest for at least 5 minutes before serving it straight from the dish.
