01 - Place chicken breasts between sheets of plastic wrap and pound to an even ½-inch thickness using a meat mallet, ensuring uniform cooking throughout.
02 - Arrange three shallow dishes: place flour in the first, beat eggs with milk in the second, and combine Parmesan, panko breadcrumbs, garlic powder, Italian seasoning, salt, and black pepper in the third.
03 - Dredge each chicken breast in flour, shaking off excess. Dip into the egg wash, then press firmly into the Parmesan-breadcrumb mixture, coating both sides evenly.
04 - Heat olive oil in a large skillet over medium-high heat. Cook chicken breasts 4 to 5 minutes per side until golden brown and the internal temperature reaches 165°F. Transfer to a plate and tent loosely with foil to keep warm.
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 - Pour in heavy cream and chicken broth, bringing to a gentle simmer. Stir in Parmesan cheese, lemon juice, salt, and black pepper. Cook for 3 to 4 minutes, whisking constantly, until the sauce coats the back of a spoon.
07 - Arrange crispy chicken breasts on a serving platter and spoon the warm creamy garlic sauce generously over the top. Finish with a scattering of chopped fresh parsley.
