Preheat your oven to 400°F (200°C). Place chicken breasts between two pieces of plastic wrap or parchment paper. Using a meat mallet or rolling pin, gently pound them to an even thickness (about 1/2 inch thick) for uniform cooking.
Set up three shallow bowls. In the first bowl, add the flour and season with a pinch of salt and pepper. In the second bowl, whisk together the eggs and Dijon mustard until well combined. In the third bowl, mix the grated Parmesan, breadcrumbs, garlic powder, Italian herbs, salt, and pepper.
Start by dredging each chicken breast in the flour, shaking off the excess. Next, dip it into the egg mixture, allowing any excess to drip off. Finally, coat the chicken in the Parmesan-breadcrumb mixture, pressing firmly to adhere the coating.
Line a baking sheet with parchment paper for easy cleanup. Place the coated chicken breasts on the baking sheet, making sure they aren’t touching. Lightly spray the tops with olive oil spray to help them crisp up in the oven.
Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through (internal temperature should reach 165°F or 75°C) and the tops are golden brown and crispy.
Once cooked, remove from the oven and let rest for a few minutes before serving.
