Prepare the Dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
Step 2: Prepare the Broccoli

Cook the Broccoli: If using fresh broccoli, steam or blanch the florets in boiling water for 3-4 minutes until just tender. If using frozen broccoli, thaw and drain any excess water.
Step 3: Make the Cheese Sauce

Combine Ingredients: In a mixing bowl, combine the softened cream cheese, heavy cream, chicken broth, garlic powder, onion powder, salt, black pepper, and paprika. Whisk until smooth and well combined.
Add Cheese: Stir in the shredded cheddar cheese and grated Parmesan cheese (if using) until mixed well.
Step 4: Assemble the Casserole

Layer the Ingredients: In the prepared baking dish, spread the cooked chicken evenly across the bottom. Add the steamed broccoli on top of the chicken.
Pour the Cheese Sauce: Pour the cheese sauce evenly over the chicken and broccoli, making sure everything is well coated.
Top with Cheese: Sprinkle extra shredded cheddar cheese on top for a delicious cheesy crust.
Step 5: Bake the Casserole

Bake: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
Step 6: Serve and Enjoy

Cool and Serve: Let the casserole cool for a few minutes before serving. This dish pairs wonderfully with a side salad or is perfect on its own for a low-carb meal.
