01 - Flatten each chicken breast to an even thickness using a meat mallet. Season both sides generously with salt and black pepper.
02 - Place the all-purpose flour in a shallow bowl, beat the eggs in a second bowl, and combine the breadcrumbs, grated Parmesan cheese, garlic powder, and paprika in a third bowl.
03 - Dredge each seasoned chicken breast in the flour, shaking off any excess. Dip into the beaten eggs, then press firmly into the breadcrumb mixture, coating both sides thoroughly.
04 - Heat the 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 a paper towel-lined plate to drain.
05 - In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté until fragrant, about 30 seconds. Pour in the heavy cream and chicken broth, bringing the mixture to a gentle simmer. Stir in the grated 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 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.
