Preparation Steps

• Preheat your oven to 400°F (200°C).
• Pat the chicken breasts dry with paper towels. If they are very thick, you can pound them slightly to an even thickness for more even cooking.
• In a small bowl, mix the olive oil, salt, and pepper.
• Brush the olive oil mixture all over the chicken breasts.
• Place the chicken breasts in a baking dish.
• Spoon the marinara sauce evenly over each chicken breast.
• Sprinkle the mozzarella cheese and Parmesan cheese over the sauce.
• Sprinkle with dried oregano.
• Bake for 20-25 minutes, or until the chicken is cooked through (internal temperature reaches 165°F or 74°C) and the cheese is melted and lightly golden.
• Let it rest for a few minutes before serving.
