Preheat oven to 350℉.
Combine together chicken breast, cream cheese, hot sauce, ranch dressing, and 1 cup of shredded cheddar cheese. Spread in the baking dish and top it with remaining cheddar cheese.
Bake it uncovered for about 30 minutes or until slightly browned and bubbly. Remove from oven then garnish it with green onion and let it sit for 10 minutes before serving.
Serve it with your favorite crackers, tortilla chips, celery stick, or carrots. Enjoy!
