Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9 by 13 inch baking dish with olive oil or butter.

In a large mixing bowl, combine the softened cream cheese, sour cream, and heavy cream. Use a whisk or a fork to blend them until the mixture is smooth and free of large lumps. Stir in the garlic powder, onion powder, smoked paprika, salt, and pepper.

Add your cooked chicken and the steamed broccoli florets to the bowl. Stir gently to ensure every piece of chicken and every floret is well coated with that luscious creamy sauce. Fold in half of the shredded cheddar cheese at this stage.

Spread the mixture evenly into your prepared baking dish. Use the back of a spoon to level it out so it cooks uniformly.

Sprinkle the remaining cheddar cheese and the parmesan cheese over the top.

Place the dish in the center rack of your oven and bake for 20 to 25 minutes. You are looking for the cheese to be bubbly and just starting to brown around the edges.

Remove from the oven and let it sit for about 5 minutes. This helps the sauce set slightly. Top with fresh green onions or crispy bacon if you are feeling fancy.
