01 - Place each chicken breast between two sheets of plastic wrap and pound to an even 1/2-inch thickness using a meat mallet or rolling pin for uniform cooking.
02 - Arrange three shallow dishes: fill the first with all-purpose flour, the second with beaten eggs combined with milk, and the third with a mixture of grated Parmesan, panko breadcrumbs, garlic powder, Italian seasoning, salt, and black pepper.
03 - Dredge each pounded chicken breast through the flour, shaking off excess, then dip into the egg wash, and finally press firmly into the Parmesan-breadcrumb mixture, ensuring an even coating on all sides.
04 - Heat olive oil in a large skillet over medium-high heat. Cook the breaded chicken breasts for 4 to 5 minutes per side until golden brown and the internal temperature reaches 165°F. Transfer to a warm plate and tent loosely with foil.
05 - Melt butter in a saucepan over medium heat. Add minced garlic and sauté for 1 minute until fragrant, being careful not to let it brown.
06 - Whisk in the heavy cream and chicken broth, bringing the mixture to a gentle simmer. Stir in Parmesan cheese, lemon juice, salt, and black pepper. Continue whisking for 3 to 4 minutes until the sauce coats the back of a spoon.
07 - Arrange the crispy Parmesan chicken on plates and spoon the warm creamy garlic sauce generously over each breast. Finish with a sprinkle of chopped fresh parsley before serving.
