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, grated Parmesan, garlic powder, and paprika in a third shallow bowl.
03 - Dredge each seasoned chicken breast in flour, shaking off any excess. Dip into the beaten eggs, then press firmly into the breadcrumb mixture, coating both sides thoroughly.
04 - Heat vegetable oil in a large skillet over medium-high heat. Once the oil is shimmering, carefully add the breaded chicken breasts. Fry for 4 to 5 minutes per side until the crust is deep golden brown and the internal temperature reaches 165°F. Transfer to paper towels to drain excess oil.
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 the mixture to a gentle simmer. Stir in grated Parmesan 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 black 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.
