Chop the broccoli into bite-sized pieces and place in a large mixing bowl.
Drizzle the broccoli with olive oil and sprinkle with the seasonings. Then toss to coat.
When the air fryer is preheated, add the water to the bottom of the air fryer pan, under the basket.
Add the broccoli to the basket and cook for 8-10 minutes, or until the broccoli is slightly crispy.
Remove the broccoli from the basket and place in another mixing bowl. Add lemon juice and toss. Transfer to a serving bowl or dinner plates and top with Parmesan before serving warm.
