Preheat oven to 375 degrees F (190 degrees C). Grease a 9x13 inch baking dish.
In a shallow bowl, mix together the bread crumbs, garlic powder, onion powder, salt, and pepper.
Brush the chicken breasts with olive oil, then dip into the bread crumb mixture to coat.
Place the chicken breasts in the prepared baking dish. Sprinkle with Parmesan cheese and parsley.
Bake in preheated oven for 25 minutes. Sprinkle mozzarella cheese over the chicken breasts, and bake an additional 10 minutes until cheese is melted and bubbly.
