Preheat the oven to 425°F (218°C).
Line a baking sheet with parchment paper.
In a medium bowl, combine the Parmesan cheese, garlic powder, dried oregano, salt, and pepper.
Add the sliced zucchinis to the bowl and toss to coat with the cheese mixture.
Drizzle olive oil over the zucchinis and toss again.
Arrange the zucchinis on the prepared baking sheet in a single layer.
Bake for 15-20 minutes or until the chips are crispy and golden brown.
Serve immediately.
