01 - Preheat the oven to 375°F. Lightly grease a 9x13-inch baking dish with cooking spray or butter.
02 - In a mixing bowl, combine the cream cheese, sour cream, milk, garlic powder, onion powder, salt, and pepper. Beat until smooth and well blended.
03 - Add the shredded chicken, cheddar cheese, and green onions to the sauce mixture. Stir until evenly incorporated.
04 - Unroll the crescent dough and separate into 8 triangles along the perforated lines.
05 - Place a heaping spoonful of the chicken mixture onto the wide end of each triangle. Roll up from the wide end to the point, enclosing the filling completely.
06 - Place the filled crescents in the prepared baking dish, arranging them in a single layer with the point sides down.
07 - Spoon any remaining chicken mixture evenly around the crescent rolls in the dish.
08 - Sprinkle the mozzarella cheese evenly over the top of the crescents and filling mixture.
09 - Bake for 25-30 minutes until the crescent rolls are golden brown and the cheese filling is bubbly around the edges.
10 - Let the dish rest for 5 minutes before serving to allow the filling to set slightly.
