Preheat and prep: Heat your oven to 375°F (190°C).
Lightly grease a 9x13-inch baking dish with olive oil or butter.
Soften the base: In a large bowl, beat the softened cream cheese until smooth. Whisk in the heavy cream until creamy and lump-free.
Add the flavor: Stir in the no-sugar BBQ sauce, garlic powder, onion powder, smoked paprika, and a pinch each of salt and pepper. Taste and adjust seasoning.
Fold in the chicken: Add the shredded chicken and half of the shredded cheese.
Mix until everything is well coated.
Assemble: Spread the mixture evenly in the prepared baking dish. Top with the remaining cheese and crumbled bacon.
Bake: Bake for 18–22 minutes, until the casserole is hot and the cheese is melted and bubbling around the edges.
Finish and serve: Let it rest for 5 minutes. Sprinkle with sliced green onions.
Serve with a side salad, roasted broccoli, or cauliflower rice.
