In a large bowl, combine the shredded chicken, buffalo wing sauce, softened cream cheese, ranch dressing, and blue cheese dressing. Mix until well combined.
Stir in half of the shredded cheddar cheese and half of the Monterey Jack cheese.
Spoon the mixture into a greased 9x13 inch baking dish.
Top with the remaining cheddar cheese and Monterey Jack cheese.
Bake for 20-30 minutes, or until bubbly and the cheese is melted and slightly golden.
Serve hot with tortilla chips, crackers, or vegetable sticks.
Notes
For a spicier dip, add a pinch of cayenne pepper or use a hotter buffalo sauce. You can also add some chopped celery for extra crunch.
