Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
Place the chicken breasts in the prepared baking dish.
In a medium bowl, combine the softened cream cheese, chicken broth, and ranch seasoning mix. Mix until smooth and well combined. This is your creamy filling.
Spoon the cream cheese mixture evenly over the top of each chicken breast, spreading it to cover the surface.
Sprinkle the mozzarella cheese and Parmesan cheese over the cream cheese topping on each breast.
Bake for 25 to 30 minutes, or until the internal temperature of the chicken reaches 165 degrees Fahrenheit and the topping is bubbly and lightly golden brown.
Remove from the oven and let the chicken rest for 5 minutes before serving. Garnish with fresh parsley.
Notes
For extra flavor, you can pound the chicken breasts to an even thickness before topping them.
If you prefer a runnier sauce, add an extra 1/4 cup of chicken broth to the cream cheese mixture.
This dish pairs well with steamed broccoli or a simple side salad.
