Preheat oven to 375°F and grease a 9 x 13 baking dish with nonstick cooking spray.
Combine chicken, tomato sauce, cooked pasta, bacon, 2 cups mozzarella cheese and 1/4 cup ranch together in a large bowl until combined. Spoon into prepared baking dish and top with remaining cheese.
Bake until sauce is bubbling and cheese is melted, about 20 minutes.
Top with parsley and drizzle with remaining ranch and hot sauce. Serve and enjoy.
