Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the shredded chicken, crumbled bacon, shredded cheddar cheese, ranch dressing, and chopped green onions. Mix well until all ingredients are evenly coated.
Carefully slice the loaf of bread into cubes, making sure not to cut all the way through the bottom crust. Leave the base intact so the loaf holds together.
Gently pry open the bread sections and fill them with the chicken, bacon, and cheese mixture. Make sure to pack the filling in generously.
In a small bowl, mix the melted butter, garlic powder, and dried parsley, then brush this mixture all over the top of the filled bread.
Wrap the loaf in parchment paper (if using) and place it on a baking tray. Bake in the preheated oven for about 20 minutes.
Remove the parchment paper and bake for an additional 10 minutes, or until the bread is golden and the cheese is bubbly.
Once done, let it cool for a couple of minutes, then pull apart and enjoy!
