Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.
In a large zipper bag or a bowl, combine the breadcrumbs, garlic powder, paprika, onion powder, dried oregano, dried thyme, salt, and black pepper, mixing until evenly distributed.
Place the chicken breasts in a large bowl. Drizzle the olive oil over the chicken and rub each piece so it is evenly coated.
Work with one chicken breast at a time: add it to the breadcrumb mixture, shake or press to coat thoroughly, then transfer the coated breast to the prepared baking sheet.
Once all chicken pieces are coated and arranged on the baking sheet, bake in the preheated oven for about 30 minutes, or until an instant-read thermometer inserted into the thickest part reads 165°F (74°C).
If the crust becomes too brown before the chicken reaches temperature, tent loosely with foil and continue baking until done.
Remove from the oven, sprinkle with freshly chopped parsley, and serve.
