Step-by-Step Instructions
1. Preheat the Oven
- Set your oven to 375°F (190°C).
- Grease a 9×13-inch baking dish to prevent sticking.
Why Grease the Dish? This prevents the casserole from sticking and makes clean-up easier.
2. Prepare the Creamy Sauce
- In a large mixing bowl, combine:
- Softened cream cheese
- Sour cream
- Heavy cream
- Minced garlic
- Onion powder, paprika, salt, black pepper, and Italian seasoning
- Stir until the mixture is smooth and creamy.
Best Tip: Let the cream cheese soften at room temperature for easy mixing.

Now that the creamy sauce is ready, it’s time to combine the ingredients and bake the casserole to cheesy perfection.
3. Assemble the Casserole
- Add the cooked chicken and broccoli florets to the bowl with the creamy sauce.
- Stir everything together until the chicken and broccoli are evenly coated.
- Mix in the shredded cheddar cheese and mozzarella cheese to enhance the flavor and creaminess.
Why Use Cooked Chicken? Pre-cooked chicken speeds up the cooking time and ensures tender, juicy chicken in every bite.
4. Transfer to Baking Dish
- Spread the chicken and broccoli mixture evenly in the greased 9×13-inch baking dish.
- Sprinkle grated Parmesan cheese over the top for a crispy, golden-brown finish.
Best Tip: If you love a crispy topping, mix Parmesan with crushed pork rinds or almond flour before sprinkling.
5. Bake the Casserole
- Place in the preheated oven (375°F/190°C).
- Bake for 20-25 minutes, until the cheese is melted and bubbly.
Optional: Broil for 2-3 minutes at the end for a golden, crispy top.
6. Let It Cool & Serve
- Allow the casserole to cool for a few minutes before serving.
- Garnish with fresh herbs like parsley or basil for a pop of color and freshness.
Best Serving Ideas:
- Pair with a fresh green salad for a complete meal.
