Equipment for Creamy Chicken and Broccoli Casserole

• 9×13-inch baking dish – standard casserole pan
• Large pot for cooking chicken
• Medium saucepan for cream sauce
• Whisk for smooth sauce
• Steamer basket or microwave-safe dish for broccoli
• Mixing bowl
• Measuring cups and spoons
• Aluminum foil (optional)

Ingredients for Creamy Chicken and Broccoli Casserole

Chicken and Broccoli

• 1½ pounds boneless skinless chicken breasts (about 3 medium breasts)
• 4 cups fresh or frozen broccoli florets (about 1 pound)
• Salt and pepper for seasoning

Creamy Sauce

• 4 tablespoons butter – creates rich base
• 4 tablespoons all-purpose flour – thickening agent
• 2½ cups whole milk – creamy foundation
• 8 ounces cream cheese, softened – luxurious texture
• 1½ cups shredded cheddar cheese – signature flavor
• 2 teaspoons garlic salt – aromatic seasoning
• ½ teaspoon black pepper – subtle heat
• ¼ teaspoon onion powder – savory depth

Cracker Topping

• 1 sleeve (about 35) Ritz crackers, crushed – buttery crunch
• 3 tablespoons butter, melted – binds the topping
• ¼ cup grated Parmesan cheese – extra flavor

Instructions for Creamy Chicken and Broccoli Casserole

Step 1: Cook the Chicken
Place chicken breasts in a large pot and cover with water. Season generously with salt and pepper. Bring to a boil over high heat, then reduce to medium-low and simmer for 15-18 minutes until chicken reaches 165°F internally. Alternatively, use 3 cups of shredded rotisserie chicken to save time.

Step 2: Prepare the Broccoli
While chicken cooks, steam the broccoli until tender-crisp, about 5-6 minutes. If using frozen broccoli, follow package directions. Drain well and pat dry with paper towels to remove excess moisture. Too much water will make the casserole watery.

Step 3: Shred the Chicken
Remove cooked chicken from the pot and let cool for 5 minutes. Shred or dice into bite-sized pieces using two forks or a sharp knife. Season lightly with salt and pepper.

Step 4: Preheat Oven
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking.

Step 5: Make the Cream Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of butter. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux. This removes the raw flour taste.

Step 6: Add Milk and Cheese
Gradually pour the milk into the roux while whisking continuously to prevent lumps. Cook for 4-5 minutes, whisking frequently, until the sauce thickens and coats the back of a spoon. Reduce heat to low.

Step 7: Finish the Sauce
Add the softened cream cheese, shredded cheddar cheese, garlic salt, black pepper, and onion powder to the sauce. Whisk until completely smooth and all cheese has melted. The sauce should be thick and creamy. Taste and adjust seasonings if needed.

Step 8: Assemble the Casserole
Spread the broccoli evenly across the bottom of the prepared baking dish. Layer the shredded chicken over the broccoli. Pour the creamy cheese sauce evenly over the chicken and broccoli, making sure everything is well coated.

Step 9: Prepare the Topping
In a mixing bowl, combine the crushed Ritz crackers, melted butter, and Parmesan cheese. Mix until the crackers are evenly coated with butter. The mixture should resemble coarse crumbs.

Step 10: Top and Bake
Sprinkle the cracker mixture evenly over the casserole. Bake uncovered for 30-35 minutes until the casserole is bubbling around the edges and the topping is golden brown. If the topping browns too quickly, tent loosely with aluminum foil.

Step 11: Rest and Serve
Remove from the oven and let the chicken and broccoli casserole rest for 10 minutes before serving. This allows the sauce to thicken slightly and makes serving easier. Serve hot directly from the baking dish.

Nutrition Facts

Nutritional Highlights

This creamy chicken and broccoli casserole provides 30 grams of protein per serving, making it exceptionally filling and satisfying. The chicken breast supplies lean protein along with essential B vitamins including niacin and B6, which support energy metabolism and nervous system function.

Broccoli contributes significant vitamin C (45% of daily value), supporting immune health and acting as a powerful antioxidant. It also provides vitamin K, folate, and fiber. The dairy components add calcium for bone health, though they also contribute to the higher fat content. This is a comfort food dish best enjoyed in moderation alongside lighter sides.

Dietitian Tips

• Lighten the sauce: Use reduced-fat cream cheese and milk to cut calories
• Boost vegetables: Add cauliflower, carrots, or mushrooms alongside broccoli
• Reduce sodium: Use low-sodium chicken broth instead of garlic salt and reduce added salt
• Add whole grains: Serve over brown rice or quinoa for extra fiber
• Increase protein: Add white beans or chickpeas for plant-based protein boost
• Control portions: Stick to one serving (1/8 of casserole) and fill half your plate with salad

Frequently Asked Questions

Can I use frozen broccoli?
Yes! Frozen broccoli works perfectly in this casserole recipe. Thaw it completely and squeeze out as much moisture as possible before using. Excess water will dilute the cream sauce and make the casserole watery. One 16-ounce bag of frozen broccoli equals about 4 cups.

Why is my casserole watery?
Watery casseroles result from excess moisture in the vegetables or not cooking the cream sauce long enough to thicken. Make sure to thoroughly drain and pat dry the broccoli. Cook the cream sauce until it visibly thickens and coats the back of a spoon before assembling the casserole.

Can I make this casserole ahead of time?
Absolutely! Assemble the entire casserole up to 24 hours before baking, cover tightly with plastic wrap or aluminum foil, and refrigerate. When ready to bake, remove from refrigerator and let sit at room temperature for 15 minutes, then bake as directed, adding 5-10 minutes to the baking time if needed.

What can I use instead of cream cheese?
You can replace cream cheese with an additional ½ cup of shredded cheddar cheese and ½ cup of sour cream. The texture will be slightly different—less thick and creamy—but still delicious. Greek yogurt also works as a lighter alternative, though it won’t be quite as rich.

How do I prevent the topping from burning?
If the Ritz cracker topping browns too quickly before the casserole is heated through, tent the dish loosely with aluminum foil. The foil allows the casserole to continue cooking while protecting the topping from over-browning. Remove the foil during the last 5 minutes if you want extra color.

Can I freeze this casserole?
Yes! You can freeze the assembled unbaked casserole for up to 2 months. Wrap it tightly in plastic wrap, then aluminum foil. Thaw overnight in the refrigerator before baking. You can also freeze leftovers in individual portions for up to 2 months. Reheat from frozen in the microwave for 4-5 minutes.
