01 - Preheat oven to 400°F. Position the rack in the center of the oven for even heat distribution.
02 - Arrange three breading stations: spread all-purpose flour on a plate, beat 2 large eggs in a shallow bowl, and combine panko breadcrumbs, grated Parmesan, garlic powder, smoked paprika, salt, and black pepper on a second plate. Mix the breadcrumb seasoning thoroughly.
03 - Pat the chicken breasts dry with paper towels. Dredge each breast in flour, shaking off excess, then dip into beaten eggs coating completely, and finally press firmly into the seasoned breadcrumb mixture, ensuring an even crust on all sides.
04 - Heat olive oil in a large ovenproof skillet over medium-high heat until the oil shimmers. Carefully place the breaded chicken breasts in the skillet and sear for 2 to 3 minutes per side until the crust turns golden brown and crispy.
05 - Transfer the skillet directly into the preheated oven. Bake for 12 to 15 minutes until the internal temperature of the thickest part of each breast reaches 165°F and the juices run clear.
06 - While the chicken bakes, melt butter in a saucepan over medium heat. Add minced garlic and sauté for about 1 minute until fragrant, stirring frequently to prevent browning.
07 - Pour in the heavy cream and chicken broth, then stir in the grated Parmesan. Simmer gently for 3 to 4 minutes, stirring continuously, until the sauce thickens and coats the back of a spoon. Stir in Dijon mustard and season with salt and pepper to taste.
08 - Remove the chicken from the oven. Spoon the creamy sauce generously over each breast and garnish with chopped fresh parsley. Serve immediately alongside steamed vegetables, mashed potatoes, or pasta.
