In a large mixing bowl, combine the shredded chicken, cauliflower rice, cream cheese, garlic powder, onion powder, smoked paprika, salt, and pepper. Mix well until everything is evenly coated.
Pour in the sugar-free BBQ sauce and gently fold it into the chicken mixture, ensuring it is well distributed.
Grease a baking dish (about 9x9 inches) with cooking spray or olive oil. Transfer the chicken mixture into the dish and spread it evenly.
Sprinkle the shredded cheddar cheese generously over the top, covering the casserole completely.
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
Once baked, remove from the oven and let it cool for a few minutes before garnishing with fresh parsley if desired.
