Transfer broccoli florets to a mixing bowl. Add oil, salt, pepper and garlic powder. If adding parmesan cheese, add now. Toss well until all broccoli florets are coated with seasoning.
Spread the broccoli in the fryer basket, in a single layer. Depending on the size of your air fryer, you may have to do this 2 batches. Push the basket in place.
Air fry at 360°F for 3-5 minutes, until the broccoli is roasted to your liking. The air fryer will take a couple of minutes to preheat, then start cooking. For crispier broccoli air fryer another 1-2 minutes.
