Preheat Oven: Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish.
Arrange Chicken: Place the chicken breasts in the prepared baking dish.
Mix Sauce: In a mixing bowl, combine the softened cream cheese, minced garlic, Italian seasoning, salt, and pepper. Gradually whisk in the chicken broth until smooth.
Pour and Spread: Pour the cream cheese sauce over the chicken breasts, spreading it evenly. Top with shredded mozzarella.
Bake: Bake in the preheated oven for 25-30 minutes, or until the chicken is fully cooked. If needed, cover loosely with foil to prevent over-browning.
Garnish: Let the chicken rest for a few minutes before garnishing with fresh parsley and serving.
