First, preheat the air fryer to 400℉
Then, once the air fryer is heated add the frozen broccoli right in. Air fry for 5 minutes to knock off the ice from the broccoli.
Now, you want to spray with oil right on top of the broccoli. Replace the air fryer basket and cook another 5 minutes. At this point judge how much more time you need. For more charred broccoli go the full 5 minutes.
Cook a remaining 5 minutes and remove the broccoli from the air fryer. Season the broccoli with your favorite garnishes with salt and pepper being classics. For a little spice, red pepper flakes are great.
