Sweet Potato Fries- Airfryer

When you say not right what do you mean exactly, like not crispy enough?

I par boil mine for a few mins, allow them to steam dry completely and then I oil and season them. They need plenty of space if you want any chance of getting some crispy edges so ensure they're spaced out evenly and not overcrowded. I turn them just after half way and they come out quite well.

Never going to be as good as restaurants who mainly deep fry them but still perfectly decent.

Depends on what they're going with, don't really use any set seasonings. Peri Peri salt is good, a bit of cumin and flaky sea salt, Hot and smoked Paprika, MSG always is a good shout (I know some people don't like using it) with some chilli powder.

Par boiling and drying them does make a difference, does add a bot of time on though. Just maker sure they're roughly the same size, well spread out and well covered with oil.

Maybe you just don't really like sweet potato fries? I don't. Ordered them way too many times before realising that I just don't care for them. They will never be like potato chips.
