Step 1

Cut the potatoes lengthwise into 1/4 inch thin slices; then cut each slice into 1/4- inch fries. (A mandolin is also helpful here).

Step 2

Spray the potatoes generously with oil.

Step 3

In batches, place the potatoes in the basket in an even layer without overlapping or crowding, air fry 380F about 7-8 minutes on each side, until golden and crisp.

Step 4

Meanwhile, in a large bowl combine chili powder, garlic powder, paprika and salt; mix in Parmesan cheese and mix well.

Step 5

When the fries are done, add to the bowl and toss to coat.

Step 6

Return back to the air fryer and cook 1 minute more.
