Preheat the oven to 425°F. Line a baking sheet with parchment paper.

Slice the zucchini into 1/8-inch thick rounds and place in a mixing bowl.

In a small bowl, combine oregano, garlic powder, salt, and black pepper.

Sprinkle the seasoning mixture over the zucchini slices and toss to coat evenly.

Place the seasoned zucchini slices in a single layer on the prepared baking sheet.

Bake for 12-15 minutes, flipping halfway through, until crispy and golden brown.

Serve immediately as a healthy snack or side dish.
