Preheat your air fryer to 400°F.
Chop fresh broccoli into florets that are similar in size, then wash and dry them well. Add your florets to a large bowl.
Combine the olive oil, melted butter, garlic powder, salt, and pepper in a small bowl.
Pour that mixture over the broccoli and toss until nicely coated.
Pour coated broccoli into your air fryer pan.
Air fry for 6 min. Then toss your florets and roast for another 6 minutes or until it reaches desired tenderness and color.
Remove from air fryer and sprinkle with freshly grated Parmesan cheese.
