Preheat your oven to 375°F (190°C). Grease a baking dish with butter or cooking spray.

In a saucepan over medium heat, combine the heavy cream, cream cheese, minced garlic, salt, and pepper. Stir until the cream cheese is melted and the mixture is smooth.

In a large mixing bowl, combine the cooked chicken, steamed cauliflower florets, shredded mozzarella cheese, and grated Parmesan cheese.

Pour the Alfredo sauce over the chicken and cauliflower mixture, stirring until everything is well coated.

Transfer the mixture to the prepared baking dish, spreading it out evenly.

Bake in the preheated oven for 20-25 minutes or until the casserole is hot and bubbly, and the cheese is melted and golden brown on top.

Once done, remove from the oven and let it cool for a few minutes before serving.

Garnish with chopped fresh parsley if desired before serving.
