How long do you air fry sweet potato?

Cubed 1-inch pieces take 12–16 minutes at 390°F (199°C), shaken at 7 minutes. Sweet potato fries take 12–16 minutes at 390°F, shaken twice. A small whole sweet potato (4–6 oz) takes 30–40 minutes, flipped at 18 minutes. A medium whole sweet potato (7–9 oz) takes 40–50 minutes. Always pierce whole sweet potatoes before cooking.

What temperature should I air fry sweet potato at?

390°F (199°C) rather than the 400°F used for regular potatoes — sweet potatoes have much higher natural sugar content and the sugars burn before the interior finishes at 400°F. The slightly lower temperature gives the inside time to cook through while the outside caramelizes rather than chars.

How do you make crispy sweet potato fries in the air fryer?

Cut into even ¼–⅜ in sticks, then soak in cold water for 20–30 minutes and pat completely dry. Toss with 1–2 tsp oil and, optionally, 1 tbsp cornstarch for extra crispiness. Cook at 390°F (199°C) for 12–16 minutes, shaking twice during cooking. They will not be as uniformly crispy as regular potato fries due to higher sugar content — slight caramelized edges are normal.

Tips

Soak sweet potato fries in cold water for 20–30 minutes to remove surface starch and improve crispiness.
Use a slightly lower temperature (390°F vs 400°F) than regular potatoes — the higher natural sugar content burns faster.
Cut pieces uniformly so they cook at the same rate; uneven cuts mean some pieces char while others stay raw.
Pierce whole sweet potatoes 6–8 times before cooking to let steam escape and prevent bursting.
A light dusting of cornstarch on cubes before oiling helps achieve a crispier exterior.

Veelgemaakte fouten

Cooking at 400°F+ for sweet potato fries — the sugar burns on the outside before the interior softens.
Skipping the soak for fries; unsoaked sweet potato fries are limp and sticky.
Not piercing whole sweet potatoes — they can build up steam pressure and burst inside the air fryer.
Overcrowding the basket; sweet potato cubes or fries pile up and steam rather than roast.
Adding honey or brown sugar glaze before cooking — it caramelizes then burns; add sweet glazes in the last 2–3 minutes only.
