Preheat oven to 375°F (190°C) and lightly grease a casserole dish with olive oil.
In a large bowl combine shredded chicken, sour cream, and cream of chicken soup.
Add garlic powder, onion powder, paprika, salt, and black pepper and mix well.
Stir in half of the shredded cheddar cheese and half of the crumbled bacon.
Spread the chicken mixture evenly into the prepared casserole dish.
Sprinkle the remaining cheddar cheese and mozzarella cheese over the top.
Add the remaining bacon and sliced green onions.
Bake for 25–30 minutes until the casserole becomes hot and bubbly.
Remove from the oven and let it rest for 5 minutes before serving.
Garnish with chopped parsley.
