Ingredients
Below are the ingredients needed to prepare this delicious casserole:
• 2 cups cooked chicken, shredded or cubed
• 4 cups fresh broccoli florets
• 1 can (10.5 oz) condensed cream of chicken soup
• 1 cup mayonnaise or sour cream
• 1/2 cup milk or chicken broth
• 1 1/2 cups shredded cheddar cheese (divided)
• 1 teaspoon lemon juice
• 1/2 teaspoon black pepper
• 1/2 teaspoon garlic powder
• 1 cup fried onions, breadcrumbs, or crushed crackers for topping
Step-by-Step Instructions
Step 1: Preheat the Oven
Set your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish to prevent sticking.
Step 2: Prepare the Broccoli
Bring a pot of salted water to a boil. Add the broccoli florets and cook for 3–4 minutes until they turn bright green and remain slightly firm. Drain them thoroughly and set them aside. This step ensures the broccoli will finish cooking evenly in the oven.
Step 3: Prepare the Creamy Mixture
In a large mixing bowl, stir together the condensed cream of chicken soup, mayonnaise or sour cream, milk or broth, lemon juice, garlic powder, and black pepper. Mix until the sauce becomes smooth and well combined.
Step 4: Combine Chicken, Broccoli, and Cheese
Add the cooked chicken pieces, drained broccoli, and 1 cup of shredded cheddar cheese to the bowl. Use a spatula to gently fold everything together until the ingredients are evenly coated in the creamy sauce.
Step 5: Assemble the Casserole
Transfer the mixture into the prepared baking dish and spread it evenly. Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
Step 6: Add the Crunchy Topping
Evenly distribute your chosen topping—fried onions, breadcrumbs, or crushed crackers—over the cheese layer. This will create a golden, crunchy crust once baked.
Step 7: Bake the Casserole
Place the baking dish in the oven, uncovered, and bake for 25–30 minutes. The casserole is ready when the edges are bubbling and the topping has turned crisp and golden brown.
Step 8: Rest and Serve
Remove from the oven and allow the casserole to rest for 5–10 minutes before serving. This helps the sauce thicken slightly and makes it easier to slice.
FAQ
Can I use frozen broccoli?
Yes. Frozen broccoli florets work well and don’t need to be thawed completely. Just be sure to drain excess moisture before mixing them into the casserole.
Can I prepare this dish ahead of time?
Absolutely. Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if it’s chilled.
What can I use instead of cream of chicken soup?
Cream of mushroom or cream of celery soup are good alternatives. Each will change the flavor slightly but still work well in this recipe.
Important Tips
For best results, always blanch the broccoli before baking. This prevents the casserole from becoming watery and helps the broccoli cook evenly. Using precooked rotisserie chicken is an excellent time-saving option. Make sure the chicken is cut into small pieces so it mixes well with the sauce.
If you're using breadcrumbs or crackers for the topping, consider mixing them with a tablespoon of melted butter for extra crispiness and flavor.
Storage Tips
Let the casserole cool completely before storing. Cover tightly and refrigerate for 3–4 days. To reheat small portions, use the microwave. For larger portions, reheat in a 350°F oven until warmed through.
This casserole can also be frozen once cooked and cooled. Wrap it tightly in plastic wrap followed by aluminum foil and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Chicken Broccoli Casserole is a simple but deeply satisfying dish that delivers comfort, convenience, and flavor. With its creamy sauce, tender chicken, and crisp topping, it’s the perfect recipe to add to your family’s collection of dependable, delicious meals.
