01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Using a meat mallet or rolling pin, pound chicken breasts to an even thickness of about 0.6 inches between two sheets of plastic wrap.
03 - Set up three shallow bowls: one with flour, one with beaten eggs mixed with milk, and one with panko breadcrumbs combined with Parmesan cheese, garlic powder, paprika, salt, and black pepper.
04 - Dredge each chicken breast first in flour, shaking off excess, then dip into egg mixture, and press firmly into breadcrumb mixture to ensure full coating on all sides.
05 - Heat oil in a large skillet over medium-high heat. Fry chicken breasts 2 to 3 minutes per side until golden brown.
06 - Transfer browned chicken breasts to prepared baking sheet and bake 12 to 15 minutes until internal temperature reaches 165°F and juices run clear.
07 - Let chicken rest for 5 minutes before serving. Garnish with chopped parsley and lemon wedges as desired.
