Preheat your oven to 225°F. Line a baking sheet with parchment paper.
In a large bowl, toss the zucchini slices with salt and let them sit for about 10 minutes to draw out moisture. Pat the slices dry with paper towels.
In a separate bowl, mix together the black pepper, garlic powder, onion powder, Parmesan cheese, and breadcrumbs.
Drizzle the olive oil over the zucchini slices and toss to coat evenly.
Dredge each zucchini slice in the breadcrumb mixture, pressing gently to adhere. Place the coated slices in a single layer on the prepared baking sheet.
Bake in the preheated oven for 1 to 1.5 hours, flipping the chips halfway through, until they are golden brown and crispy.
Remove from the oven and let cool for a few minutes before serving.
