1. Preheat the Oven and Prepare the Dish: Start by preheating your oven to 375 F (190 C). Lightly grease an 8×8 inch baking dish or a similar-sized oven-safe serving dish. This prevents the dip from sticking and makes cleanup easier.

2. Shred the Chicken: If you haven’t already, shred your cooked rotisserie chicken. You can do this by hand, using two forks, or even a stand mixer with the paddle attachment for a super quick method. Aim for bite-sized pieces that will mix well into the dip.

3. Combine Creamy Ingredients: In a large mixing bowl, combine the softened cream cheese, buffalo wing sauce, ranch dressing, and blue cheese dressing. Use a rubber spatula or a hand mixer on low speed to blend these ingredients until they are smooth and well combined. Make sure there are no large lumps of cream cheese.

4. Add Chicken and Cheese: Fold the shredded chicken into the creamy mixture. Then, stir in 1 cup of shredded cheddar cheese until everything is evenly distributed. The mixture will be thick and rich.

5. Transfer to Baking Dish: Spoon the entire dip mixture into your prepared baking dish, spreading it out evenly with your spatula.

6. Top with More Cheese: If using, sprinkle the crumbled blue cheese over the top of the dip. This adds an extra layer of flavor and a beautiful golden crust as it bakes.

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

8. Garnish and Serve: Carefully remove the dish from the oven. If desired, garnish with freshly sliced green onions for a pop of color and freshness. Serve immediately with your favorite dippers.
