Preheat oven to 400°F (200°C).
Set up a breading station with three shallow dishes: one with flour, one with beaten eggs, and one with a combined mixture of breadcrumbs, Parmesan, garlic powder, oregano, salt, and pepper.
Dredge each chicken breast in the flour, shaking off the excess.
Dip the floured chicken into the egg wash to coat completely.
Press the chicken into the breadcrumb and Parmesan mixture, ensuring an even coating on both sides.
Heat olive oil in a large oven-safe skillet over medium-high heat.
Sear the chicken for 3 minutes per side until the crust is golden brown.
Transfer the skillet to the preheated oven and bake for 8 to 10 minutes until the internal temperature reaches 165°F (74°C).
Remove from oven and let the chicken rest for 5 minutes before serving.
