Preheat the oven to 190°C/375°F. Line a baking sheet with parchment paper.
In a food processor, combine the breadcrumbs, anchovies, parmesan, garlic, parsley, oregano, and a pinch of salt and pepper. Pulse until the garlic and parsley are finely chopped and the mixture is homogenous.
Use a mandolin or potato peeler to thinly slice the zucchini lengthwise into long strips. Arrange the zucchini on the baking sheet, add the bay leaves and the breadcrumb mixture, and toss to coat. Drizzle with olive oil.
Transfer the baking sheet to the oven and cook until the zucchini are golden-brown and the outside is slightly crispy, about 20 minutes. Rotate the pan halfway through cooking if it doesn't seem to be cooking evenly.
Remove and discard the bay leaves. Transfer the zucchini to a large plate and drizzle with additional olive oil. Sprinkle with the remaining parsley and serve.
