Preheat your oven to 400°F (200°C). Prepare a baking sheet by lining it with parchment paper and lightly greasing it with olive oil.
In a shallow bowl, combine the grated Parmesan cheese, panko breadcrumbs, Italian seasoning, garlic powder, onion powder, and a pinch of salt and pepper. Stir until evenly distributed.
In a separate mixing bowl, crack the two large eggs and whisk them together with the Dijon mustard until smooth.
Place the flour in another shallow dish for dredging the chicken.
Season both sides of each chicken breast lightly with salt and pepper. Coat a chicken breast in the flour, shaking off excess.
Dip the flour-coated chicken breast into the egg mixture, ensuring it is evenly coated.
Roll the egg-coated chicken breast in the Parmesan-breadcrumb mixture, pressing down lightly to ensure the coating sticks.
Continue dredging, egging, and coating the remaining chicken breasts until all are covered.
Place the coated chicken breasts on the prepared baking sheet, evenly spaced apart. Drizzle olive oil over the top of each piece.
Transfer the baking sheet to the preheated oven and bake for 25-30 minutes until the crust is golden brown and the internal temperature reaches 165°F (74°C).
Remove the chicken from the oven and let it rest for about 5 minutes before serving.
