1 large sweet potato, scrubbed and cut into 1/4-inch-thick slices
1/2 teaspoon kosher salt
2 tablespoons unsalted butter
2 slices whole-wheat bread, ground in a food processor (1 cup)
1/2 cup grated Parmesan (2 ounces)
Freshly ground black pepper
How to Make It
Heat oven to 500° F. Pour the oil into a baking pan, add the sweet potato, and toss to coat. Arrange the slices in a single layer and sprinkle with the salt. Roast until softened and browned, about 20 minutes.
Meanwhile, melt the butter in a large skillet over medium-low heat. Add the bread crumbs and toast until golden. Add in the Parmesan, potato, and a few grinds of pepper; toss to coat. Return to the baking pan. Place in oven and bake until the cheese bubbles, about 3 minutes. Add salt to taste.
