  • 5 pounds medium sweet potatoes

  • 3 cups Rice Krispies

  • 1/4 teaspoon baking soda

  • 1/4 teaspoon kosher salt, plus more for seasoning

  • 1/8 teaspoon cayenne, plus more for seasoning

  • 1/2 cup plus 2 tablespoons sugar

  • 6 1/2 tablespoons unsalted butter, plus more for serving

  • 1/4 cup heavy cream

  • 1/2 teaspoon finely grated orange zest

  • Freshly ground black pepper


  1. Preheat the oven to 350° and line a large rimmed baking sheet with foil. Prick each potato all over with a fork and transfer to the baking sheet. Bake the potatoes until tender, about 1 hour; turn the potatoes over halfway through baking. Let cool slightly.

  2. Meanwhile, lightly coat a large rimmed baking sheet and 2 large spoons with nonstick cooking spray. Lightly coat a large heatproof bowl with nonstick cooking spray and put the Rice Krispies in it. In a small bowl, mix the baking soda with the 1/4 teaspoon of salt and 1/8 teaspoon of cayenne. In a medium saucepan, combine the sugar with 1/2 tablespoon of the butter and 1/4 cup of water and bring to a boil, stirring until the sugar dissolves. Boil over moderately high heat, swirling the pan occasionally, until a golden caramel forms, about 7 minutes. Remove from the heat and stir in the baking soda mixture; the caramel will foam. Immediately drizzle all of the hot caramel over the cereal and, using the 2 greased spoons, quickly toss to coat. Spread the topping on the prepared baking sheet in an even layer and let cool completely, then break into pieces.

  3. Scoop the sweet-potato flesh into a food processor. Add the remaining 6 tablespoons of butter and the cream, orange zest and a generous pinch of cayenne and puree until smooth. Season with salt and black pepper. Transfer the sweet potatoes to a serving bowl and dollop with additional butter. Serve, passing the crispy rice topping at the table.

Make Ahead

The pureed sweet potatoes can be refrigerated for 2 days; reheat gently before serving. The crisp rice topping can be stored in an airtight container for 1 week.
