Preheat and prep: Heat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil or butter.
Cook the bacon: Crisp the bacon in a skillet over medium heat, then drain on paper towels and crumble. Set aside.
Warm the cream base: In a large bowl, beat the softened cream cheese until smooth.
Stir in sour cream and mayonnaise until creamy.
Season it up: Add ranch seasoning, garlic powder, onion powder, smoked paprika, and pepper. Mix until fully combined.
Add chicken and cheese: Fold in the shredded chicken, 1 cup of the cheddar, most of the bacon (reserve some for topping), and the sliced green onions.
Assemble the bake: Spread the mixture evenly in the baking dish. Top with the remaining 1/2 cup cheddar and the reserved bacon.
Bake: Place on the center rack and bake for 18–22 minutes, until the edges are bubbling and the cheese is melted with light golden spots.
Garnish and rest: Let it rest for 5 minutes.
Sprinkle with extra green onions and parsley before serving.
