Preheat the oven to 400°F (200°C).
If needed, place the chicken breasts between two sheets of plastic wrap and pound them to an even thickness using a meat mallet or rolling pin.
In the first shallow dish, season the flour with salt and pepper. In the second dish, whisk the eggs until well combined. In the third dish, mix together the breadcrumbs, Parmesan cheese, garlic powder, onion powder, Italian herbs, salt, and pepper.
Dip each chicken breast in the flour, shaking off any excess, then coat it in the egg wash, and finally press it into the breadcrumb mixture, ensuring an even coating.
Place the coated chicken breasts on a baking sheet lined with parchment paper. If using olive oil, spray over the chicken to help it crisp up. Otherwise, drizzle olive oil over the top.
Bake in the preheated oven for 20 minutes or until the chicken is cooked through and golden brown on the outside. The internal temperature should reach 165°F (75°C).
Remove from the oven and allow the chicken to rest for a few minutes before serving.
