First, cut up the zucchini in quarters or slices but at least 1/4 inch thick. Then, in a bowl toss them in oil. Make sure they are coated well. Now, add in the salt, pepper and parmesan cheese.
Preheat air fryer to 400℉.
Add the prepped zucchini into the air fryer basket then cook for 7-9 minutes. Flip halfway through. Start checking for doneness around the 7 minute mark.
Once finished, allow to cool a bit then serve.
