Ken says
This looked good to me. Evidently my air fryer is way different. So far I checked at 20 minutes, still hard, 30 minutes still hard. I set for another 15 minutes and waiting to see if it is tender in that time.
Kristy says
Hi! It definitely shouldn’t take more than 30 minutes, did you use a sweet Vidalia onion and is the air fryer and onion hot? What air fryer are you using?
Sarah says
Did you preheat the air fryer? Is your onion very large?
Kristy says
Medium sized onion, I don’t normally preheat unless specifically mentioned. If you do preheat just take a few minutes off the cooking time.
Jen says
I am so glad I found this! Did exactly as stated, except pierced a bunch of holes on the inside (not all the way through, just enough for the flavor to really get in there) with a fork, and *poof*. Roasted onion perfection.
Thank you for this recipe!!

I just attempted this recipe with one of my fresh Vidalia onions and I had the same issues that Ken did in other posts. I have a Ninja Foodi Grill Air Fryer and have great success with it but tho I followed the recipe exactly the onion never did get soft…extended the time twice to cook a total of 35 minutes and finally gave up and put it in the microwave. Tastes great but not a great air fryer method. Sorry to say. Even increased temp to 400. Onion was hot but still hard.

This was delicious. Cooked in a Cosori Air Fryer and took 40 minutes. But definitely worth the wait.
