Preheat an oven to 350°F, and place a rack in the middle position.
Add cream cheese, ranch dressing, ranch dressing powder, and 1/4 cup crumbled blue cheese to a large bowl, stirring to combine. Fold in shredded chicken and hot sauce, and mix until evenly combined.
Transfer chicken mixture to a small, shallow baking dish, and bake for 20 minutes until mixture is warm and the edges start to bubble. As soon as the mixture comes out of the oven, top with remaining 1/2 cup crumbled blue cheese.
Right before serving, sprinkle the dip evenly with chopped bacon, sliced scallions and fresh parsley. Serve with Food Should Taste Good Lime Tortilla Chips and ice cold IPAs.
