Preheat your oven to 350°F (175°C). Preheating ensures that your dish cooks evenly and achieves that perfect crispy exterior.
Mix the filling: In a large mixing bowl, combine 1 (8 oz) package of softened chive & onion cream cheese, 1 cup of Ranch dressing, 1 ½ tsp of garlic salt, and 1 tsp of onion powder. Stir until smooth, and then gently fold in 3 cups of chopped rotisserie chicken, 6 slices of crumbled turkey bacon, 3 medium chopped green onions, and 1 cup of shredded Colby-Jack cheese until everything is well combined.
Prepare the bread: Take your 1 (16 inch) loaf of Italian bread and slice it in half lengthwise. Carefully hollow out the inside, leaving a shell around the crust to hold the filling.
Assemble the bread: Spread half the remaining 2 cups of shredded Colby-Jack cheese inside the hollowed-out loaf. Next, spoon in the creamy filling and spread it evenly. Top with the last 1 cup of shredded cheese before placing the other half of the bread back on top to seal it.
Brush the outside with melted butter: Using a brush, apply 1 Tbsp of melted butter on the outer crust of the bread to give it that inviting golden color.
Wrap in foil: Tightly wrap the entire stuffed loaf in aluminum foil to keep it moist while baking.
Bake in the preheated oven for 30-40 minutes: This will allow all the flavors to meld together. For the last 5 minutes, uncover the bread to crisp up the crust.
Serve warm: Once baked, let the stuffed bread sit for about 5 minutes before slicing. This will make it easier to cut and serve. Enjoy your delightful creation!
