Preheat Oven & Prepare Dish: Preheat your oven to 375°F (190°C). Lightly grease an 8x8 inch baking dish or a shallow 1.5-quart oven-safe dish.

Shred Chicken: If using canned chicken, drain it thoroughly and shred it into small pieces using two forks. If using leftover cooked chicken, shred it similarly. Place the shredded chicken in a large mixing bowl.

Combine Wet Ingredients: Add the softened cream cheese, buffalo wing sauce, and ranch dressing (or blue cheese dressing) to the bowl with the shredded chicken.

Add Cheese (Part 1): Add 1 cup of the shredded sharp cheddar cheese and 1/4 cup of the shredded Monterey Jack cheese to the bowl. Reserve the remaining cheese for the topping.

Mix Thoroughly: Using a sturdy spoon or spatula, mix all the ingredients together until well combined. Ensure the cream cheese is fully incorporated and evenly distributed throughout the chicken mixture.

Transfer to Baking Dish: Spoon the chicken mixture into the prepared baking dish, spreading it out evenly.

Add Topping: Sprinkle the remaining 1/2 cup of sharp cheddar cheese and 1/4 cup of Monterey Jack cheese evenly over the top of the dip.

Bake: Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the dip is hot, bubbly around the edges, and the cheese on top is melted and lightly golden brown.

Garnish & Serve: Carefully remove the dip from the oven. If desired, sprinkle with fresh chopped chives or sliced green onions for a pop of color and freshness. Serve immediately with your favorite dippers like crackers, tortilla chips, celery, and carrot sticks.
