Add frozen sweet potato fries to the air fryer basket or tray in a single layer. If desired, you can brush oil on the basket first and or spray the frozen fries with oil.
Place basket or tray in the preheated air fryer and air fry for 12 minutes. You can flip them once if you'd like but we find that unnecessary for a small batch.
When cooking time is up, use silicone tongs to remove the fries from the air fryer basket or tray.
Notes
Preheat the air fryer to 400°F before you cook frozen fries. This will help them cook evenly.Spray or toss them with cooking oil before air frying for crispy sweet potato fries.Serve with your favorite dipping sauce on the side.Add seasonings or toppings after cooking.
