Preheat the oven to 375 degrees.
In a skillet over medium heat, fry the bacon until crispy. Set aside on a paper towel-lined plate to cool, then chop.
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 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.
