Broccoli-Cheddar Quiche with Sweet Potato Crust

To prepare crust: Preheat oven to 400 degrees F. Coat a 9-inch deep-dish pie pan with cooking spray. Stir sweet potato, 1 egg, Parmesan, 1/4 teaspoon salt and 1/8 teaspoon pepper together in a medium bowl. Transfer the mixture to the prepared pan and press it evenly into the bottom and up the sides of the pan. Bake until the crust is set and beginning to brown around the edges, about 25 minutes.

To prepare filling and bake quiche: Evenly scatter broccoli, Cheddar and shallots over the crust. Whisk eggs and sour cream in a small bowl until smooth. Whisk in milk, salt and pepper. Pour the egg mixture over the other filling ingredients. Reduce oven temperature to 350 degrees F. Bake the quiche until the filling is set in the center and beginning to brown slightly, 35 to 45 minutes. Let cool slightly before serving.
