Preheat oven to 350°F (175°C). Grease a 9x13-inch baking dish.
Cook pasta al dente, drain, and set aside.
In a large bowl, whisk together cream cheese, sour cream, chicken broth, ranch seasoning, garlic powder, onion powder, and black pepper.
Add shredded chicken, pasta, turkey bacon, and 1 cup cheddar cheese. Stir to combine.
Transfer to the baking dish, top with remaining cheese, and bake for 25-30 minutes until bubbly.
Let rest for 5 minutes, garnish with green onions and parsley, and serve.
