01 - Preheat your oven to 375°F. Line a baking sheet with parchment paper to prevent sticking.
02 - In a spacious mixing bowl, combine the shredded chicken, softened cream cheese, ranch dressing, buffalo wing sauce, shredded mozzarella, and shredded cheddar cheese. Mix thoroughly until all ingredients are well blended and consistent.
03 - Carefully slice the top third off the French bread loaf lengthwise. Using a spoon or your hands, hollow out the inside of the loaf, leaving approximately a 1/2-inch thick shell. Reserve the removed bread for other culinary applications.
04 - Evenly spoon the prepared buffalo chicken dip mixture into the hollowed cavity of the French bread loaf. Carefully transfer the stuffed loaf onto the previously lined baking sheet.
05 - Bake the stuffed bread for 25–30 minutes, or until the filling is visibly bubbly and the exterior of the bread achieves a golden-brown crispness.
06 - Remove the baked bread from the oven and allow it to cool for 5 minutes. Garnish generously with chopped green onions and fresh parsley before serving.
07 - Slice the warm dip-stuffed bread into portions and serve immediately as a delicious appetizer.
