Put it aside and let it cool for a while. When it is cooled to room temperature, cut the sweet potato or purple potato into strips with a knife. Pay attention to the thickness of each sweet potato strip when cutting. Ensure that sweet potato strips taste better!
Then you can go to the oven. The oven is preheated about ten minutes in advance. This can appropriately increase or decrease the preheating time according to your actual situation. After preheating, we will adjust the ignition of the oven to about 200 degrees, the small fire to about 200 degrees, and the oven time to 20 minutes. Turn it over after 20 minutes, so that the color will be more uniform.
After baking, our sweet potato strips are almost ready. Dip in ketchup and eat it. It's really delicious!
