Preheat your oven to 375°F (190°C). This ensures the dip will bake evenly and get that perfect bubbly texture on top.
In a large bowl, warm cream cheese in the microwave for about 45 seconds until softened. This will make it easier to mix with the other ingredients.
Add mayonnaise, hot sauce, and garlic to the softened cream cheese, and whisk until everything is well combined. The mixture should be smooth and creamy.
Stir in the shredded cooked chicken, 1½ cups of Pepper Jack cheese, 6 tablespoons of blue cheese (if using), and the chopped scallions. Fold these ingredients gently to maintain a nice texture.
Transfer the mixture into a 1½-quart (1.5-L) baking dish, spreading it out evenly. You want to ensure every bite has that delightful blend of flavors.
Sprinkle the remaining Pepper Jack cheese and 2 tablespoons of blue cheese on top. This creates a delicious cheesy crust that will melt beautifully.
Place the dish in the preheated oven and bake the dip for about 20 minutes, or until it’s bubbling. You’ll know it’s ready when you see those delightful bubbles popping up!
Next, turn on the broiler and broil the dip 6 inches (15 cm) from the heat for a few minutes until the top is lightly browned. Keep a close eye on it to avoid burning!
Once it’s golden and bubbly, let the dip stand for 5 minutes. This allows it to firm up slightly and makes it easier to serve.
Finally, sprinkle with additional scallions for garnish and serve warm with tortilla chips, carrots, and celery sticks. Enjoy!
