Wash and grate the zucchini. Transfer to a bowl and squeeze well with your hands to remove as much water as possible.
Add the parmesan to the zucchini and mix thoroughly to combine into a sticky, cheesy mixture.
Spoon small portions of the mixture onto a baking sheet lined with parchment paper. Press each one down into a thin, compact round.
Bake at 180°C (360°F) for about 20 minutes, or until golden and crispy.
Let cool slightly, then serve and enjoy!
