Peel and discard the skin. Trim of the pointy ends.
Now cut the potato in half lengthwise.
Then again cut it crosswise.
If your sweet potato is thick then slice it in half.
Cut each slice into ¼-½ inch thick fries. Don’t cut the fries too thin otherwise, they will get chewy and might get burned. Keep in mind that fries will shrink in size after cooking.
Air Frying:
Take cut fries into a bowl. Add cornstarch and all the seasonings (salt, pepper, cayenne pepper, garlic powder and chaat masala).
Toss everything until seasoning and flour are coated evenly on the fries.
Add oil. Toss again to coat well.
Add them into the air fryer basket and spread them into a single layer.
Air fry at 400°F for around 12-15 minutes. Shake the basket halfway through for even browning. Depending on the thickness of your fries, it may take a couple of minutes more or less.

Notes
Cut the fries into even thickness and length. So all of them get air-fried at the same time.
Do not overcrowd the air fryer basket. Make sure the fries are in a single layer otherwise they won’t become crisp. They will get cooked but will stay soft.
Halfway through the cooking process turn over the fries for even browning and cooking.
No need to soak the fries after cutting as we do in french fries (made from regular potatoes). Sweet potatoes don’t have that much starch in them, so no worry about soaking them.
Cornstarch or arrowroot flour or rice flour is added to make the fries a little extra crispy.
Serve them ASAP. As they cool down they will become soft, soggy and lose their crispness.
