Preheat oven to 350 degrees F.
In a large bowl, add cream cheese, shredded cheddar cheese, sour cream, wing sauce, and shredded chicken. Mix thoroughly to incorporate all ingredients.
Transfer dip into a 9” cast iron skillet. Use a spatula to evenly distribute the dip, and smooth the surface.
Place in the oven, and bake for 20 minutes. Broil the dip for an additional 5 minutes.
Remove from oven, and garnish with sliced green onions if desired. Serve warm with veggie sticks, such as celery, or low carb tortilla chips.
