Preheat the oven to 375°F.
In a skillet over medium heat, fry the bacon until crispy. Set aside.
In a large bowl, combine the shredded chicken, cream cheese, Buffalo sauce, ranch dressing, and bacon; mix well. (If desired, reserve some of the bacon to sprinkle on top, as pictured.)
Transfer the chicken mixture to a shallow 1-quart baking dish and bake for 20 minutes, until warm throughout.
Garnish with chopped green onions, if desired.
