4Preheat your oven to 375°F (190°C).
Season the chicken breasts with salt and pepper on both sides.
Heat the olive oil in a large oven-safe skillet over medium-high heat.
Add the chicken breasts to the skillet and cook for 3-4 minutes on each side, until golden brown.
Remove the skillet from heat and pour the marinara sauce over the chicken breasts.
Sprinkle the shredded mozzarella cheese evenly over the chicken and sauce.
Top with grated Parmesan cheese.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.
Remove from the oven and let it rest for a few minutes before serving.
Serve hot and enjoy your Baked Chicken Parmesan!
