Preheat your air fryer to 400 ° F | 205 ° C for 5 minutes.

Cut the sweet potatoes into long "fry-like" strips

Mix the salt and pepper in with the olive oil - and brush liberally to the fries.

NOTE: This is a neat trick to stop finely ground ingredients like salt and pepper from being blown around inside the air fryer.

Spray the bottom and sides of the air fryer with oil. Add your fries to the air fryer in a single layer.

Cook the sweet potato fries for 20 minutes at 400 ° F | 205 ° C.

NOTE: Sweet potatoes tend to dry out A LOT causing them to burn, so use oil liberally to help retain moisture.

Check your sweet potato fries for desired crispiness. It can take up to 35 minutes for your sweet potato fries to become crispy. Sweet potatoes are quite a bit denser than regular potatoes.

While the sweet potato fries are air frying, make the garlic mayonnaise. Combine the mayonnaise, garlic, and lemon juice and stir until smoothly blended.

Be sure to toss the fries periodically throughout the cooking process to make sure they are cooking evenly.

Plate and enjoy!
