I do sweet potato fries in the air fryer, made from fresh, not frozen, and they turned out good. I made the standard orange variety, then I did the Japanese purple and white varieties. I read that regular potato fries turn out good too, I read that you should soak them in water for 30 minutes before you fry them (drying them off first of course).
Good idea Dave. I'll have to try sweet potatoes done this way. It doesn't seem that difficult as compared to potatoes. It seems with potatoes it's more involved.
Air fried potato fries taste good, but it can't compare to deep-fried ones as far as texture goes, but it's a lot more convenient to use an air fryer.
