Preheat the oven: Set to 400°F (200°C).
Lightly grease a 9x13-inch baking dish with olive oil or cooking spray.
Prep the chicken: Pat the chicken dry with paper towels. If the breasts are thick, slice them horizontally to create thinner cutlets or gently pound to even thickness. This helps them cook evenly.
Season well: Drizzle chicken with 1 tablespoon olive oil.
Sprinkle both sides with salt, pepper, and the Italian seasoning. Add minced garlic or garlic powder. Toss to coat.
Layer the sauce: Spread about 1 cup of marinara over the bottom of the baking dish.
This prevents sticking and keeps the chicken juicy.
Add chicken to the dish: Lay seasoned chicken in a single layer over the sauce. Avoid overlapping pieces.
Top with sauce: Spoon the remaining marinara evenly over the chicken. You want good coverage, but don’t drown it; too much liquid can make it watery.
Add cheese: Sprinkle mozzarella over the top, followed by half of the Parmesan.
Optional crisp topping: In a small bowl, mix bread crumbs with 1 tablespoon olive oil and a pinch of salt and pepper.
Stir in the remaining Parmesan. Sprinkle this over the cheese for a golden, crunchy finish.
Bake: Place in the oven and bake for 20–25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Broil briefly: If you want extra color, broil for 1–2 minutes at the end. Watch closely to avoid burning.
Rest and garnish: Let it rest for 5 minutes so the juices settle.
Sprinkle with chopped basil or parsley.
Serve: Spoon over cooked pasta, zucchini noodles, or polenta. It’s also great with a green salad and garlic bread.
