Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius) and grease a 9x13 inch baking dish.
Arrange the chicken breasts in a single layer in the prepared baking dish.
In a medium mixing bowl, whisk together the dry ranch seasoning, condensed cream of chicken soup, sour cream, and black pepper until well combined.
Pour the creamy mixture over the chicken breasts, spreading it evenly to cover each piece.
Bake in the preheated oven for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165 degrees Fahrenheit (74 degrees Celsius).
Sprinkle the shredded cheddar cheese and bacon bits over the top of the chicken.
Bake for an additional 3 to 5 minutes until the cheese is melted and bubbly.
Remove from the oven and garnish with fresh parsley before serving.
