Baked sweet potato in the air fryer
A baked sweet potato takes 45 to 60 minutes at 385°F (195°C) in an air fryer, shaken or turned at 25 minutes.
What to know about air frying a baked sweet potato
Cosori gives a 9 to 10 oz whole sweet potato 385°F for 45 to 60 minutes — the longest cook in this index, longer even than a regular baked potato on the same chart. Sweet potato is denser and wetter than a floury white potato, so heat takes longer to reach the middle and there is more water to drive off once it gets there. The reward is that the sugars caramelise and often weep out through the skin, which is a sign it has worked rather than a fault.
The mistake people make
Pulling it at the point a white potato would be done. Sweet potato goes from firm to properly creamy quite abruptly and very late, so a potato that felt nearly ready at forty minutes is genuinely different at fifty-five. Under-baked sweet potato tastes starchy and vegetal rather than sweet.
How to tell when it's done
A skewer meets no resistance at all at the centre, and the potato collapses slightly when squeezed rather than springing back. Dark syrupy patches leaking through the skin are a good sign, not a burnt one.

Questions people ask
How long does a baked sweet potato take in an air fryer?
45 to 60 minutes at 385°F, shaking or turning at 25 minutes. That figure comes from Cosori. Cook times shift with the size and power of your machine, so treat the lower end as the point to start checking.
What temperature should I air fry a baked sweet potato at?
385°F, or about 195°C. That sits inside the 350–400°F band the USDA describes as typical for air frying.
Can you air fry a baked sweet potato?
Yes. Use a light spray of oil. Keep it to a single layer — crowding the basket blocks the air circulation the machine depends on, which the USDA specifically warns about. Preheat the machine first.
How do you know when a baked sweet potato is done in an air fryer?
A skewer meets no resistance at all at the centre, and the potato collapses slightly when squeezed rather than springing back. Dark syrupy patches leaking through the skin are a good sign, not a burnt one.
