FAQs
It depends on how crispy you like them. For crunchy, golden onions, they should air fry for about 20 to 23 minutes. For tender and soft onions, cook them for only 10 to 15 minutes.
The onions are cooked at 300ºF to start, then increased to 400ºF in the last 2 to 3 minutes. This way, the onions are able to tenderize and soften before becoming crispy near the end.
Skipping the oil could lead to dried out and burnt onions, so I don’t recommend leaving it out.
Store the air fryer onions in an airtight container in the fridge for up to 4 days. They’ll lose their crispy crunch after chilling, but you can get this back by reheating them for a few minutes in the air fryer.
