01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with oil.
02 - In a large bowl, combine ground chicken, egg, breadcrumbs, garlic, green onions, onion powder, smoked paprika, salt, and pepper. Mix gently until just incorporated, being careful not to overwork the meat.
03 - With lightly dampened hands, shape the mixture into 20 uniform meatballs, approximately 1 tablespoon each. Place on the prepared baking sheet, spacing evenly apart.
04 - Bake for 18-20 minutes until golden brown and fully cooked through. Internal temperature should reach 165°F when tested with a meat thermometer.
05 - While meatballs bake, melt butter in a small saucepan over low heat. Whisk in hot sauce, Worcestershire sauce, and garlic powder until smooth and well combined. Remove from heat.
06 - Transfer cooked meatballs to a large serving bowl. Pour prepared buffalo sauce over the meatballs and toss gently until evenly coated.
07 - Arrange meatballs on a serving platter. Sprinkle generously with crumbled blue cheese and fresh chives or parsley. Serve immediately with celery and carrot sticks on the side.
