Begin by preheating your oven to 350°F (175°C). This ensures that your dip will bake evenly and reach that perfect gooey consistency.
In a large mixing bowl, combine the softened cream cheese and mayonnaise. Use a spatula to mix until smooth and creamy. This will be the base of your dip.
Next, fold in the cooked and shredded chicken, 1 cup of the shredded cheese, and the can of diced green chiles (including their juices). Stir until everything is well combined.
Spoon the mixture into your prepared baking dish, spreading it out evenly. Top with the remaining 1/2 cup of shredded cheese for an extra cheesy topping.
Place the dish in the oven and bake for about 20-25 minutes or until the dip is bubbly and golden.
Once out of the oven, sprinkle chopped fresh cilantro on top for a pop of color and flavor. Serve immediately with tortilla chips for dipping.
