Savory Sweet Potato Crumble

Monday, November 21, 2016

Growing up, we had sweet potatoes with toasted marshmallows more times than I can count. I wanted to come up with a recipe for sweet potatoes that were every bit as decadent as the ones my brothers and I loved as kids, but with a more interesting and savory flavor profile for Thanksgiving. This Savory Sweet Potato Crumble hits all those marks – and let’s just say, it goes a lot better with turkey and gravy than marshmallows do.

The crumble is made with walnuts, flour, fresh sage, brown sugar, Parmesan, a touch of heat from crushed pepper flakes, and of course, a generous amount of butter. It’s essentially a mash-up of Thanksgiving stuffing and a cheesy bread crumb topping. The potatoes underneath are creamy and studded with shallots caramelized in brown butter. Together, the crisp, savory crumble and slightly sweet, oniony potatoes are a winning pair, and you won’t believe how much the house smells like pure Thanksgiving when this dish is in the oven. If you're looking for a great twist on traditional holiday sweet potatoes, these are a real showstopper and definitely not your average side dish. (And they don’t just have to be for Thanksgiving, either!)

Savory Sweet Potato Crumble

serves 8-10

  • 4 pounds sweet potatoes, scrubbed (6 medium)
  • 2 cups thinly sliced shallots (about 6 large)
  • 9 tablespoons (1 stick + 1 tablespoon) unsalted butter, at room temperature, divided
  • 4 tablespoons light brown sugar, divided
  • 1 ½ cups finely chopped walnuts
  • ¾ cup all purpose flour
  • 1 cup grated Parmesan cheese
  • 2 tablespoons finely chopped fresh sage
  • 1/2 teaspoon crushed red pepper flakes, divided
  • ½ cup whole milk
  • kosher salt

Preheat the oven to 400 degrees.

Prick the potatoes several times with the tines of a fork, and bake for 45 minutes to one hour, or until tender when pierced with a knife. Set aside until cool enough to handle, then peel and discard the skins.

Meanwhile, make the brown butter shallots. Heat 4 tablespoons of the butter in a medium (10-inch) sauté pan. Cook the butter over medium-low heat for three minutes, watching carefully, until brown flecks begin to form. Immediately add the shallots and 1 tablespoon of the brown sugar. Lower to the heat to low and cook, stirring occasionally, for 20 minutes, until the shallots are tender and lightly caramelized.  Set aside.

In a medium bowl, combine the walnuts, flour, Parmesan, sage, ¼ teaspoon of the red pepper flakes, 2 tablespoons of the brown sugar, the remaining 5 tablespoons butter, and 1 teaspoon salt. Using your fingers, pinch the mixture together to form large crumbles. Set aside.

With a hand mixer on low speed or a potato masher, beat the potato mixture until smooth. Fold in the shallot mixture, the remaining tablespoon of brown sugar, the milk, the remaining 1/4 teaspoon red pepper flakes, and 2 teaspoons salt, and combine.

Lower the oven temperature to 375 degrees. Transfer the potato mixture to a 9×13-inch baking dish.  Sprinkle the crumble mixture evenly over the potatoes and bake for 30 minutes, until the topping is browned and the potatoes are heated through. Serve hot.

Note: The crumble can be assembled up to the point of baking and stored in the refrigerator, covered, overnight. It may take a few extra minutes in the oven.
