1, need to turn over. Brush the sweet potato with a brush, cut off both ends, and wipe the skin with a kitchen towel. Preheat the air fryer for 3 minutes, put the sweet potato into the basket of the air fryer, set the temperature at 200 degrees for 20 minutes, open it after 20 minutes, take out the basket, and turn it over with heat-insulating gloves. Every sweet potato should be turned over. After turning over, close the basket and set the time to 20 minutes.

2. Whether it is necessary to put oil in the air fryer for baking sweet potatoes depends on the situation. If the whole sweet potato is not peeled and roasted, it is very convenient to adjust the temperature and time, about 200 degrees for 30 minutes. For larger sweet potatoes, it takes a relatively long time and will be cooked at that time. However, in the case of baking sweet potato strips or slices, because the sweet potato has been peeled, direct heating will lose the moisture in the food, resulting in dry taste. It is suggested that if you want to have a better taste, you can put oil in it, so as to keep the moisture inside the sweet potato, which will make the taste crisp outside and tender inside.
