Preheat to 400F, if your air fryer doesn't automatically do this for you just manually turn your model on for 3-5 minutes before cooking.
Lay the frozen air fryer sweet potato fries in a single layer, leaving space around the fries for best results.
Set the air fryer to a cook time of 12-15 minutes.
Flip the frozen sweet potato fries in the air fryer after 8 minutes if you have a basket style air fryer. Ours took a total of 12 minutes to cook, so 8 minutes on one side and 4 minutes on the other.
If you have a basket style air fryer, we recommend shaking the sweet potato frozen fries every 5 minutes.
Notes
Keep your sweet potato fries frozen and don't defrost them before cooking.
For crispier sweet potato fries, be sure to leave some space around the fries so the air can circulate.
Give the fries a shake or toss at least once during the cook-time.
Remember: Do not use cooking spray on a non-stick basket as it will ruin the non-stick finish.
Serve your fries as a side dish or as part of an appetizer spread.
