Preheat the oven to 400°F and line a baking sheet with parchment paper.
In a shallow bowl, whisk the eggs with a fork. In a second bowl, mix the panko breadcrumbs, Parmesan cheese, garlic powder, Italian seasoning, salt, and pepper.
Dip each chicken breast into the egg, then press it into the breadcrumb mixture to coat both sides evenly. Place the coated breasts on the prepared baking sheet.
Lightly spray the tops of the chicken with olive oil spray. Bake for 20 minutes.
Remove the sheet from the oven and spoon marinara sauce over each piece of chicken. Sprinkle mozzarella cheese on top. Return to the oven for 8 more minutes until the cheese melts and the coating is golden.
While the chicken finishes baking, cook the linguine in a large pot of salted boiling water according to package directions. Drain the pasta.
Divide the linguine among four plates. Place one piece of chicken on each portion of pasta and garnish with fresh basil leaves.
