Step 1

Preheat the oven to 375°F.

Step 2

In a large bowl, warm the cream cheese in the microwave until softened, about 45 seconds. Add the mayonnaise, hot sauce, and garlic and whisk until combined. Stir in the chicken, 1-1/2 cups of the pepper jack, 6 tablespoons of the blue cheese, and the scallions. Transfer the mixture into a 1-1/2 quart baking dish and sprinkle the remaining 1/2 cup of pepper jack and 2 tablespoons of blue cheese over top.

Step 3

Bake the dip for about 20 minutes, until bubbling. Turn on the broiler and broil 6 inches from the heat until lightly browned on top, a few minutes. Let stand for 5 minutes, then sprinkle with scallions and serve warm with tortilla chips and celery sticks.

Step 4

Note: A 1-1/2 quart baking dish is a slightly unusual size. If you're uncertain about the size of your baking dish, you can determine how many quarts it holds by filling it with water, one cup at a time. A 1.5 quart dish will hold 6 cups of water.
