Preheat the oven to 375°F (190°C).

In a shallow dish, mix the flour, garlic powder, onion powder, paprika, salt, and pepper.

In another shallow dish, beat the eggs.

In a third dish, combine the panko breadcrumbs, Parmesan cheese, and mozzarella cheese.

Dredge each chicken breast first in the flour mixture, coating evenly, then dip into the beaten eggs, and finally press into the breadcrumb mixture, ensuring it is fully coated.

Heat olive oil and butter in a large oven-safe skillet over medium heat. Once the oil is hot, add the chicken breasts and cook for 3–4 minutes on each side, until golden brown.

Transfer the skillet to the preheated oven and bake for 10–12 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and is fully cooked.

Remove from the oven, garnish with chopped parsley, and serve.
