Begin by preheating your oven to 375°F. Generously season both sides of your chicken breasts with garlic powder, salt, and freshly ground pepper.
Heat olive oil in a large skillet over medium heat, then sear each chicken breast for about 2-3 minutes per side. This step ensures the chicken develops a beautiful golden crust and stays juicy.
Transfer the seared chicken breasts to your greased baking dish. Pour marinara sauce generously over each piece, ensuring they’re well-coated. Top the marinara with a sprinkle of freshly grated Parmesan cheese, followed by a layer of shredded mozzarella. The duo of cheeses creates a richly flavorful crust that’s irresistible.
Place the baking dish in the preheated oven and bake for 20-25 minutes. You’ll know it’s done when the chicken reads 165°F internally on a thermometer and the cheese is melted and bubbling.
For that restaurant-style touch, broil the dish for an additional 2-3 minutes to lightly brown the cheese. Keep a close eye to avoid burning!
Once baked, remove the dish from the oven and allow the chicken to rest for 5 minutes. This step locks in the juices, making every bite tender and flavorful. Garnish with fresh parsley or basil for a vibrant finish, and serve immediately!
