Preheat air fryer to 400 degrees F for 5 minutes. Spray inside of basket with olive oil spray.
Pour frozen veggies into basket and spread out so they overlap the least amount possible.
Cook for 8-10 minutes total. Shake basket after minute 4 and spray top contents with olive oil spray. Check after minute 8 to see if they are as tender as you'd like. If not add 1-2 minutes.
If you want the edges crispier, spray with olive oil spray again for another minute.
