Preparing Balsamic Baked Chicken Breast with Mozzarella Cheese is straightforward. Just follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).

2. Prepare Marinade: In a bowl, mix balsamic vinegar, olive oil, garlic powder, Italian seasoning, salt, and pepper.

3. Marinate Chicken: Place the chicken breasts in a resealable bag or shallow dish. Pour the marinade over the chicken, ensuring each piece is well-coated. Allow the chicken to marinate in the refrigerator for at least 30 minutes (or up to 2 hours for enhanced flavor).

4. Bake Chicken: Transfer the marinated chicken to a baking dish. Pour any leftover marinade over the top of the chicken.

5. Add Cheese: Top each chicken breast with slices of fresh mozzarella cheese.

6. Bake in Oven: Cook in the preheated oven for 25-30 minutes or until the chicken reaches an internal temperature of 165°F (75°C) and the mozzarella is bubbly and golden.

7. Garnish: Once done, remove from the oven and let it rest for a few minutes. Garnish with fresh basil leaves if desired.

8. Serve: Plate the chicken, drizzling with extra balsamic reduction if you have it. Enjoy your delicious meal!
