Preheat your oven to 400°F (200°C).
Prepare a baking sheet by lining it with parchment paper.
In a shallow bowl, mix together the grated Parmesan cheese, breadcrumbs, garlic powder, onion powder, salt, and pepper.
In a separate bowl, beat the eggs until frothy.
Dip each chicken breast into the egg mixture, allowing excess to drip off.
Coat each chicken breast in the Parmesan mixture, pressing down lightly to adhere.
Place the coated chicken onto the prepared baking sheet and drizzle lightly with olive oil.
Bake in the preheated oven for 25–30 minutes, or until the chicken is cooked through and the crust is golden.
Let the chicken rest for a few minutes before serving.
