Preheat the oven to 400°F (200°C) and line a rimmed baking sheet with parchment paper or a silicone mat.
In a shallow dish, combine the panko breadcrumbs, grated Parmesan cheese, oregano, basil, garlic powder, onion powder, salt, and pepper.
Place the flour in a separate shallow dish and the beaten egg in another.
Pat the chicken breasts dry with paper towels. Dredge each breast in the flour, shaking off any excess.
Dip the floured chicken into the beaten egg, then press firmly into the Parmesan-herb mixture to ensure an even coating on all sides.
Arrange the coated chicken breasts on the prepared baking sheet and drizzle lightly with olive oil.
Bake for 20 to 25 minutes, or until the breading is golden brown and the internal temperature of the chicken reaches 165°F (74°C).
Remove from the oven and let rest for 5 minutes before serving.
