Onions are also great, roasted. Use a little butter.
You got me to thinking about using the air-fryer instead of in the oven. It might be faster.
Do some shallots :)
last time I roasted garlic I used the air fryer and it worked great!
I started at 390 for a few minutes, went down to 350 and noticed it was still browning too quickly, so I dropped it to 325 and let it got for about 5 minutes.
I also roasted Jalapenos at the same time.
