Preheat the oven broiler to a medium setting.
In a small bowl, combine the dried basil, dried parsley, ground oregano, salt, pepper and the olive oil to make a herbed oil.
Brush or rub the herbed oil on both sides of each chicken fillet.
Heat a large oven-proof skillet over high heat and add the chicken. Pan-fry until golden, about 3 minutes per side.
Reduce heat to medium-high, add the minced garlic to the pan and cook until fragrant, about 30 seconds.
Spoon the marinara sauce over and around the chicken, stir in the Italian seasoning, then sprinkle the shredded mozzarella evenly over the fillets.
Place the skillet under the broiler and cook until the cheese melts and the chicken is cooked through, about 3–5 minutes.
Remove the chicken from the pan. Add the reserved pasta water and the cooked pasta to the skillet, and stir until the sauce slightly thickens and becomes glossy.
Serve the mozzarella chicken over the sauced pasta or alongside vegetables or salad.
