01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Pat the chicken breasts dry with paper towels and season both sides generously with salt and freshly ground black pepper.
03 - Arrange three shallow bowls for breading. In the first bowl, place the all-purpose flour. In the second bowl, whisk together the eggs and milk. In the third bowl, combine the breadcrumbs, grated Parmesan cheese, garlic powder, and dried Italian herbs, mixing thoroughly.
04 - Dredge each seasoned chicken breast in the flour, shaking off any excess. Dip into the egg mixture, allowing the coating to adhere evenly. Press firmly into the breadcrumb-Parmesan mixture, ensuring a complete, even crust on all sides.
05 - Heat olive oil in a large skillet over medium-high heat. Carefully add the breaded chicken breasts and fry for 3 to 4 minutes per side until the crust turns a deep golden brown and becomes crispy.
06 - Transfer the seared chicken breasts to the prepared baking sheet. Bake for 10 to 12 minutes, or until the internal temperature reaches 165°F when checked with a meat thermometer.
07 - While the chicken finishes baking, melt the butter in a saucepan over medium heat. Add the minced garlic and sauté for approximately 1 minute until fragrant, taking care not to let it brown.
08 - Pour in the heavy cream and add the Parmesan cheese, dried thyme or Italian herbs, salt, and pepper. Simmer gently over medium-low heat, stirring constantly, until the sauce thickens and coats the back of a spoon, about 3 to 4 minutes. Remove from heat.
09 - Arrange the crispy Parmesan chicken breasts on plates and drizzle generously with the creamy garlic sauce. Sprinkle with freshly chopped parsley and serve immediately alongside pasta, mashed potatoes, or steamed vegetables.
