1. Direct baking: Wash the sweet potato, control the moisture, put it in a 200-degree air fryer for 30 minutes, insert it with chopsticks, and insert it easily, indicating that it is cooked. Bake it undercooked for 5- 10 minutes. Best served with cheese or butter.

2. Wrap it in tin foil: wash the sweet potato, control the moisture, wrap it in tin foil, put it in a 200-degree air frying pan and fry it for 30 minutes, and hear the "hissing" sound of the sweet potato. After baking, remove the tin foil and serve.

3. Steaming before baking: clean the sweet potato, control the moisture, steam it in a steamer, and then put it in an air fryer 180 degrees 10- 15 minutes to smell the sweet potato. You can eat it directly after baking, or you can eat it with cheese and butter.
