Preheat your oven to 375°F (190°C). This ensures that your dip will bake evenly and come out perfectly melted and bubbly.
In a large bowl, warm the cream cheese in the microwave for about 45 seconds until it's softened. You want it to be easy to mix. This will help combine all the ingredients smoothly.
Add in the mayonnaise, hot sauce, and garlic to the bowl. Whisk these together until you achieve a well-blended mixture. You should see a beautiful creamy consistency with just a hint of red from the hot sauce.
Now, stir in the shredded chicken, 1½ cups of the Pepper Jack cheese, 6 tablespoons of the blue cheese (if using), and the scallions. This is where the magic happens - the flavors meld together beautifully, and you can get a whiff of the deliciousness.
Transfer the mixture into a 1½-quart baking dish. Spread it out evenly, and smooth the top with a spatula.
Sprinkle the remaining Pepper Jack cheese and 2 tablespoons of blue cheese over the top. This will create a deliciously cheesy crust when baked.
Bake the dip for about 20 minutes until it’s bubbling. This is where you start to get excited as the aroma fills your kitchen!
Next, turn on the broiler and broil about 6 inches from the heat until the top is lightly browned, which should take just a few minutes. Watch it closely to prevent burning.
Once done, let the dip stand for 5 minutes to cool slightly. This helps the flavors settle and makes it easier to scoop.
Finally, sprinkle some chopped scallions on top for garnish and serve warm with your choice of tortilla chips, carrots, and celery sticks. Enjoy!
