Baked Sweet-Potato Chips

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

1 lime, cut into wedges, for serving

Preheat oven to 400°, 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, and serve with lime wedges.
