01 - Flatten each chicken breast to an even thickness using a meat mallet. Season both sides generously with salt and black pepper.
02 - Place flour in one shallow bowl, beaten eggs in a second, and combine breadcrumbs, Parmesan cheese, garlic powder, and paprika in a third.
03 - Dredge each seasoned breast in flour, shaking off excess. Dip into beaten eggs, then press firmly into the breadcrumb mixture, coating evenly on all sides.
04 - Heat vegetable oil in a large skillet over medium-high heat. Once the oil shimmers, add the breaded chicken breasts. Fry for 4 to 5 minutes per side until deeply golden and cooked through to an internal temperature of 165°F. Transfer to paper towels to drain.
05 - In a saucepan, melt butter over medium heat. Sauté minced garlic until fragrant, about 30 seconds. Pour in heavy cream and chicken broth, bringing to a gentle simmer. Stir in Parmesan cheese and Dijon mustard. Continue simmering for 2 to 3 minutes until the sauce thickens and coats the back of a spoon. Season with salt and pepper to taste.
06 - Arrange the crispy chicken on serving plates and spoon the warm creamy sauce generously over each piece. Garnish with chopped fresh parsley if desired. Serve immediately alongside mashed potatoes, steamed vegetables, or pasta.
