Preheat oven to 350 degrees F (175 degrees C).
Combine 1 1/2 cup Italian cheese blend, garlic, basil, and oregano in a bowl. Combine Parmesan cheese and bread crumbs in a separate bowl.
Bake in the preheated oven until chicken is no longer pink in the center and the juices run clear, about 45 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Pour spaghetti sauce over cooked chicken; top with 1/4 cup Italian cheese blend. Bake until sauce is bubbling and cheese is melted, about 5 more minutes.
