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 dish. Beat the eggs in a second shallow dish. Combine the breadcrumbs, grated Parmesan cheese, garlic powder, and paprika in a third shallow dish.
03 - Dredge each seasoned chicken breast in flour, shaking off any excess. Dip into the beaten eggs, allowing the surplus to drip off. Press firmly into the breadcrumb mixture, ensuring an even, thorough coating on all sides.
04 - Heat vegetable oil in a large skillet over medium-high heat. Once the oil is shimmering and hot, carefully 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 a paper towel-lined plate to drain.
05 - In a saucepan, melt the butter over medium heat. Sauté the minced garlic 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.
