Preheat the oven to 400°F (200°C) and lightly oil an 8×8-inch baking dish.
In a large mixing bowl, combine the shredded cooked chicken, softened low-fat cream cheese, hot sauce, shredded mozzarella, and plain Greek yogurt until smooth and evenly mixed.
Stir in the chopped green onion, garlic powder, and onion powder until evenly distributed.
Transfer the mixture to the prepared baking dish and spread into an even layer.
Sprinkle the shredded cheddar cheese evenly over the top of the dip.
Bake for 16–20 minutes, or until the dip is hot and bubbly and the cheese is melted.
Let cool for a few minutes before serving.
Notes
Use rotisserie or leftover chicken to save time.
Adjust hot sauce to taste for milder or spicier dip.
Softening the cream cheese first ensures a smoother dip.
