Wash the sweet potatoes, scrub them to get rid of the dirt.
Peel them and cut them lengthwise into ¼ inch thick slices.
Place these slices on a parchment-lined baking tray.
Drizzle olive oil on top on both sides and sprinkle a little salt as well.
Place the baking tray in a preheated oven at 400 degrees F for about 30 minutes.
Top them with your favorite topping and serve.
