The creamy base that binds the casserole and adds classic flavor.
Sour Cream
Adds tanginess and keeps the filling silky smooth.
Cheddar Cheese
Sharp cheddar gives a rich, cheesy depth that complements the broccoli.
Garlic & Onion Powder
Enhances flavor without overpowering the other ingredients.
Stuffing Mix

Chicken Broth
Softens the stuffing and infuses it with extra flavor.

Tips & Tricks
Use Fresh Ingredients
Whenever possible, use fresh broccoli and freshly cooked chicken to enhance the overall flavor and texture of the casserole.
Don't Overcook the Broccoli
Steam the broccoli just until tender-crisp to ensure it retains its vibrant color and doesn't become mushy in the casserole.
Customize Your Cheese
Feel free to mix in other cheeses like mozzarella or pepper jack for a more complex flavor profile.
Pro Tips
- For a deeper flavor, toast the stuffing mix lightly before mixing with broth and butter.
- Let the casserole cool slightly before serving to allow the layers to set for easier slicing.
- Experiment with different herbs in the stuffing mix for a unique twist.
Step-by-Step Instructions
Prepare Your Oven and Dish
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to prevent sticking.
Combine the Filling Ingredients
In a large bowl, combine shredded chicken, steamed broccoli, cream of chicken soup, sour cream, half the cheese, garlic powder, onion powder, salt, and pepper. Mix until smooth and well blended.
Prepare the Stuffing Mixture
In a separate bowl, stir together the stuffing mix, chicken broth, and melted butter until moistened.
Layer the Casserole
Spread the chicken-broccoli mixture evenly in the prepared baking dish, then spoon the stuffing mixture over the top and spread it out evenly.
Add a Cheesy Topping
Sprinkle the remaining cheddar cheese on top for a golden, gooey finish.
Bake to Perfection
Bake for 30–35 minutes, or until the casserole is bubbly and the top is lightly browned.
Let It Rest
Let the casserole rest for 5 minutes before serving for easier slicing and to allow flavors to meld.
Delicious Variations
Add Extra Veggies
Mix in carrots, peas, or green beans for more color and nutrients.
Cheesy Twist
Use a blend of cheddar and mozzarella or pepper jack for a spicier kick.
Creamy Alternative
Substitute cream of mushroom or cream of celery soup for a different flavor profile.
