Add the broccoli, olive oil, and seasonings to a bowl and mix. Rinse the bowl and set aside.
Place the seasoned broccoli in the air fryer cooking pot in an even layer.
Cook at 400 degrees for 5-8 minutes per side. I like to cook these for 10 minutes on one side, flip the broccoli, and cook for an additional 2-5 minutes.
Remove the broccoli from the cooking basket and place them back in the bowl. Toss them in the melted butter and parmesan right before serving.

Notes
Cut the broccoli into similar-sized florets so it cooks evenly.
Arrange the broccoli in an even layer for better browning.
Cook less for tender broccoli or a little longer for darker roasted edges.
Add the butter, Parmesan, and optional lemon after air frying.
