With help of a sharp knife, cut them into 1/4 - 1/2 inch pieces.
Soak it in cold water for 10 minutes.
Preheat the air fryer at 390 F for 4 minutes.
In the mean while, remove the fries from water and wipe them with a paper napkin.
Place the fries in a large bowl.
Add the spices mentioned above in the ingredients list above.
Drizzle 2 - 3 tsp oil and now mix them nicely with the sweet potato fries.
Now when the air fryer beeps, remove the basket and transfer the seasoned fries into the basket.
Then set timer at 12 minutes at 390 F (200C).
Toss them in the midway or at every 5 minutes to ensure even cooking.
If you like half cooked sweet potatoes, check at 10 minutes if you can remove. If you love crispier fries, try for 2 - 3 minutes extra (14 - 15 minutes)

Notes
Cut them evenly. This will help them to cook evenly and faster in your air fryer.
You will need a sharp knife to cut the sweet potatoes since these are a little harder in texture than potatoes (denser than potatoes).
Preheat the air fryer. Though it's not compulsory and many brands say it's not required, it's easier to track the timing while making fries.
Shake the basket every 4 minutes. This ensures even-cooking and faster cooking of the fries. They may get burnt if left untouched in the basket for too long.
