Remove the pan-fried chicken to a baking sheet. Transfer the chicken to the 350°F oven and bake for 10–15 minutes, or until cooked through. The exact time will depend on the thickness of your chicken breasts.
While the chicken bakes, bring a large pot of water to a rolling boil for your pasta. Cook the pasta according to package directions; angel hair typically takes 3–5 minutes, while thicker pastas like penne will need more time.
Once the chicken is cooked, pull it from the oven and top each piece with 1 cup of mozzarella cheese. Return it to the oven just until the cheese is bubbling and melted. To serve, plate the cooked pasta first, then top with a chicken cutlet, and spoon over the warm pasta sauce. If you have some on hand, a sprinkle of fresh shaved Pecorino-Romano or grated Parmesan cheese is a nice finish.
