01 - Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
02 - Pat chicken breasts dry with paper towels and season both sides generously with salt and freshly ground black pepper.
03 - Arrange three shallow bowls: fill the first with all-purpose flour, the second with eggs whisked together with milk, and the third with a mixture of breadcrumbs, grated Parmesan, garlic powder, and dried Italian herbs.
04 - Dredge each seasoned chicken breast in flour, shaking off any excess. Dip into the egg mixture, allowing the excess to drip off, then press firmly into the breadcrumb-Parmesan mixture, ensuring an even, thorough coating 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 coating is golden brown and crispy.
06 - Transfer the seared chicken to the prepared baking sheet and bake for 10 to 12 minutes, or until the internal temperature reaches 165°F (75°C).
07 - While the chicken bakes, melt butter in a saucepan over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.
08 - Stir in heavy cream, Parmesan cheese, dried thyme, salt, and pepper. Simmer gently, stirring constantly, for 3 to 4 minutes until the sauce thickens to a silky consistency. Remove from heat.
09 - Arrange the crispy Parmesan chicken breasts on plates, drizzle generously with the creamy garlic sauce, and sprinkle with chopped fresh parsley. Serve immediately.
