Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease with cooking spray.
Place the chicken breasts between two sheets of plastic wrap and pound them to an even thickness of about 1 inch.
Set up a breading station: In one shallow bowl, place the flour and season with salt and pepper. In a second bowl, whisk the eggs until well-beaten.
In a third bowl, combine the grated Parmesan cheese, breadcrumbs, garlic powder, onion powder, and Italian herbs. Mix well.
Dredge each chicken breast in flour, shaking off excess, then dip it in the beaten eggs, and finally coat it with the Parmesan-breadcrumb mixture.
Place the coated chicken breasts onto the prepared baking sheet. Drizzle the melted butter over the tops.
Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the coating is golden brown and crispy.
In a small saucepan over medium heat, warm the heavy cream until slightly thickened. Season with salt and pepper to taste.
Once the chicken is done, remove from the oven and let rest for a few minutes. Serve hot, drizzled with the warm heavy cream sauce, and garnish with freshly chopped parsley.
