Yes! Just like baked fries, air-fried mashed potato sticks would also taste delicious and crispy! Spray the sticks with cooking oil, or you can also spray the air frying basket. Ensure both sides are coated with a good amount of spray (nothing too much) before you air-fry them.  Preheat the air-fryer to 400℉, and add a single layer of fries at a time. Too many layers can result in uneven cooking and soggy fries. Air-fry for 10-15 minutes, and you have it— delicious and crispy mashed potato fries.
