1. If the chicken is not already cooked, place the chicken breasts in a large pot of boiling water. Cover, remove from heat, and let cook for about 25 minutes or until fully cooked through. Shred the chicken and set aside.

2. Preheat the oven to 350°F. Lightly coat a 9×9-inch baking dish with nonstick cooking spray.

3. In a medium saucepan over medium-low heat, combine the cream cheese, ranch dressing, hot sauce, black pepper, and garlic powder. Stir continuously until the cream cheese is fully melted and the mixture is smooth.

4. Remove the saucepan from the heat. Stir in the shredded chicken, green onions, 1 cup mozzarella cheese, and 1 cup cheddar cheese until evenly combined.

5. Transfer the mixture to the prepared baking dish. Sprinkle the remaining mozzarella and cheddar cheese evenly over the top.

6. Bake for 20–30 minutes, or until the dip is hot and bubbling around the edges.

7. Switch the oven to broil and cook for another 2–3 minutes, just until the cheese on top turns golden brown. Watch carefully to prevent burning.

8. Serve warm with tortilla chips, crackers, toasted bread, or fresh vegetable sticks.
