STEP 5/6
Please put it on the pan. Bake at 200 degrees for 10 minutes, turn it upside down, bake about 10 more, and don't take it out right away, but drain more moisture with oven heat. And you can just cool it down and eat it. If you take it out right away, it's a soft sweet potato stick.
The temperature of the oven varies from house to house, so you have to watch it at first. You can ride it because you don't have much time. The sweet potatoes may not be cooked over time. Don't be on time, but keep your oven temperature.
