Creating Garlic Parmesan Chicken Bake is straightforward. Just follow these steps:

1. Preheat your oven to 375°F (190°C). Prepare a baking dish by greasing it with olive oil.
2. In a large bowl, combine the grated Parmesan cheese, sour cream, mayonnaise, minced garlic, Italian seasoning, salt, and black pepper. Mix until well incorporated.
3. Take the chicken breasts and pat them dry. Season each breast lightly with salt and pepper.
4. Coat each chicken breast generously with the Parmesan mixture from the bowl, ensuring it’s well-covered.
5. Place the coated chicken breasts in the greased baking dish.
6. In a small bowl, combine breadcrumbs with a drizzle of olive oil. Mix well to make sure the breadcrumbs are slightly damp.
7. Sprinkle the breadcrumb mixture evenly over the top of the chicken breasts.
8. Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the chicken is cooked through and the top is golden brown.
9. Use a meat thermometer to ensure the chicken has reached an internal temperature of 165°F (74°C).
10. Once done, remove the dish from the oven and let it rest for a few minutes before serving.
