Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Preheat the oven to 400°F (204°C). Prick the sweet potatoes several times with a fork, rub them all over with the veggie oil, and set them on a baking sheet.

  2. Bake the sweet potatoes for about 60 minutes, until a knife slides easily through the center. Let them cool for 10 minutes, then lower the oven to 375°F (190°C).

  3. Cut each potato in half lengthwise. Scoop the flesh into a bowl, leaving the shells intact, and set the shells on a baking sheet.

  4. Mash the flesh with 3 tablespoons of the melted butter, the maple syrup, bourbon, cinnamon, 1/2 teaspoon of the nutmeg, the crème fraiche or cream cheese, salt and pepper until smooth.

  5. Spoon the filling back into the shells, mounding it slightly.

  6. In a small bowl, combine the hazelnuts (pecans or walnuts also work, optional), panko, remaining 3 tablespoons melted butter, remaining 1/2 teaspoon nutmeg, and a pinch of salt. Sprinkle over the potatoes.

  7. Bake for 25 minutes, until the topping is golden and the filling is hot throughout. Let rest 5 minutes before serving.
