Wash the cauliflower, and break into bite sized florets if using a full head of cauliflower, rather than a precut bag of florets.
Add the olive oil, parmesan, and garlic to a large bowl and stir well to mix together.
Add the cauliflower florets, and mix around to coat the cauliflower with the mixture.
Add a single layer to the air fryer basket, and air fry for 14 minutes, at 400 degrees, shaking the basket once about halfway through cooking.
Remove from the air fryer, and serve hot!
