Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper for easy cleanup.
In a shallow bowl, beat the eggs and mix in the Dijon mustard until smooth.
In another shallow bowl, combine the grated Parmesan cheese, panko breadcrumbs, Italian seasoning, garlic powder, onion powder, salt, and pepper. Mix well to combine all dry ingredients.
Take each chicken breast and dip it into the egg mixture, coating it completely. Allow any excess to drip off.
Next, transfer the chicken to the breadcrumb mixture, pressing down firmly to ensure a good coating on both sides. Place the coated chicken breasts on the prepared sheet pan.
Lightly spray the tops of the chicken breasts with olive oil spray to aid in browning.
Bake in the preheated oven for 25-30 minutes or until the chicken is cooked through (internal temperature of 165°F or 75°C) and the topping is golden and crispy.
Once done, remove from the oven and let it rest for 5 minutes. Garnish with chopped fresh parsley before serving.
Notes
Serve the chicken on a platter, garnished with additional parsley and a side of roasted vegetables for a colorful meal.
