Food & Cooking Recipes Appetizers Finger Food Recipes Baked Sweet-Potato Chips 3.2 (1,255) Prep Time: 5 mins Total Time: 30 mins Servings: 4 A mandoline or a hand-held slicer will quickly turn out thin, even slices of sweet potato, although a sharp knife and a steady hand will also work fine. Directions 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, and serve with lime wedges.
