Creating Balsamic Baked Chicken Breast with Mozzarella Cheese can be simple if you follow these easy steps:

1. Marinate the Chicken: In a medium bowl, whisk together the balsamic vinegar, olive oil, minced garlic, Italian herbs, salt, and pepper. Add the chicken breasts to the marinade, ensuring they are fully coated. Cover and refrigerate for at least 30 minutes.
2. Preheat the Oven: Preheat your oven to 400°F (200°C).
3. Prepare the Baking Dish: Lightly grease a baking dish with cooking spray or a small amount of olive oil.
4. Arrange the Chicken: Place the marinated chicken breasts in the prepared baking dish, pouring any remaining marinade over the top.
5. Bake the Chicken: Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
6. Add the Mozzarella: Remove the baking dish from the oven. Top each chicken breast with slices of fresh mozzarella cheese.
7. Broil for Perfection: Return to the oven and switch to the broil setting. Broil for an additional 3-5 minutes, or until the cheese is melted and bubbly.
8. Garnish and Serve: Remove from the oven and let the chicken rest for a few minutes. Garnish with fresh basil leaves if desired.
