Preheat the oven to 375°F (190°C) and lightly grease a 9x13 inch ceramic or glass baking dish.
In a large mixing bowl, combine the softened cream cheese, heavy whipping cream, chicken bone broth, garlic powder, onion powder, smoked paprika, salt, and black pepper. Whisk vigorously until the texture is smooth and emulsified.
Add the shredded cooked chicken and steamed broccoli florets to the bowl. Fold gently with a spatula until all components are thoroughly coated in the cream sauce.
Transfer the mixture into the prepared baking dish, spreading it into an even layer using the back of a spoon.
Distribute the shredded sharp cheddar cheese evenly over the top, followed by the crumbled bacon pieces.
Place the dish on the center rack of the oven and bake for 20-25 minutes, or until the sauce is bubbling at the edges and the cheese has reached a golden-brown melt.
Optional: Switch the oven to the broiler setting for the final 2 minutes to achieve a crispier cheese crust.
Remove from the oven and allow the casserole to rest for 5 minutes to set before garnishing with fresh parsley and serving.
