Creating Balsamic Baked Chicken Breast with Mozzarella Cheese can be incredibly simple by following these easy steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C) to ensure even cooking.
2. Prepare the Marinade: In a small bowl, mix the balsamic vinegar, olive oil, minced garlic, Italian seasoning, salt, and pepper.
3. Marinate the Chicken: Place the chicken breasts in a baking dish and pour the balsamic marinade over them, ensuring they are fully coated. Let them marinate for at least 15 minutes (or longer for deeper flavor).
4. Bake the Chicken: Transfer the baking dish to the preheated oven. Bake for about 20 minutes.
5. Add the Cheese: After 20 minutes, remove the dish from the oven and carefully add the shredded mozzarella cheese on top of each chicken breast.
6. Continue Baking: Return the dish to the oven and bake for an additional 10-15 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.
7. Check Doneness: Ensure the chicken reaches an internal temperature of 165°F (75°C) for safety.
8. Garnish: Once done, remove from the oven and let it rest for a few minutes. Garnish with fresh basil leaves if desired.
9. Serve: Slice and serve warm, drizzling any remaining balsamic glaze from the dish over the top.
