Trim the chicken and cut it into serving-size pieces.
In a medium bowl, whisk together the egg and lemon juice.
Place the chicken pieces in the egg mixture, cover, and refrigerate for thirty minutes.
Preheat your oven to 400°F. Line a baking sheet with parchment paper or foil.
In a shallow dish, whisk together the breadcrumbs, grated Parmesan cheese, lemon zest, garlic powder, salt, and pepper.
Dip each piece of chicken into the breadcrumb mixture, coating both sides evenly.
Place the coated chicken pieces on the prepared baking sheet.
Lightly spray the chicken with cooking spray for added crispness.
Bake the chicken in the preheated oven for 15 minutes, then flip the pieces and bake for an additional 10 minutes.
Serve your Parmesan crusted chicken warm, accompanied by fresh lemon slices.
