Preheat your oven to 400°F (200°C) and prepare a baking sheet by greasing it with olive oil or lining it with parchment paper.

In a large mixing bowl, whisk together olive oil, garlic powder, dried oregano, salt, and black pepper.

Slice the zucchini into 1/4-inch rounds and toss them in the seasoning mixture until fully coated.

In a separate bowl, combine mozzarella cheese, Parmesan cheese, and breadcrumbs to create a topping.

Dip each zucchini slice into the cheese-breadcrumb mixture and set aside on a plate.

Arrange coated zucchini slices in a single layer on the prepared baking sheet with space between them.

Bake in the preheated oven for 20 to 25 minutes until cheese is melted and golden brown.

Let the dish cool for a few minutes before garnishing with parsley and serving.
