Sweet Potato Chips

Serves 4
2 medium sweet potatoes, scrubbed and sliced 1/8 inch thick
1 tablespoon extra-virgin olive oil
1/2 teaspoon coarse salt, preferably sea salt
Preheat oven to 400 degrees, with racks in center and lower positions. Divide sweet potatoes between 2 rimmed baking sheets. Drizzle with oil, toss, and spread them in a single layer on sheets. Bake, flipping once, until centers are soft and edges are crisp, 22 to 25 minutes. Sprinkle with salt.
