• 2 tbsp all-purpose flour

Step-by-Step Instructions for Chicken Broccoli Alfredo Casserole

Step 1: Preheat and Prepare Ingredients

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray. If you haven’t already, cook and dice the chicken and steam or blanch the broccoli until just tender.

Step 2: Cook the Pasta

Bring a large pot of salted water to a boil and cook the pasta until al dente. Drain and set aside.

Step 3: Make the Alfredo Sauce

In a large saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Stir in the flour and cook for another minute, whisking continuously to form a roux.

Slowly pour in the milk and heavy cream, whisking constantly to prevent lumps. Add salt, black pepper, Italian seasoning, and red pepper flakes. Cook for about 3–4 minutes until the sauce thickens slightly. Stir in the Parmesan cheese and remove from heat once melted and smooth.

Step 4: Combine the Ingredients

In a large mixing bowl, combine the cooked pasta, chicken, and broccoli. Pour the Alfredo sauce over the mixture and gently stir until everything is well coated.

Step 5: Assemble the Casserole

Transfer the mixture to the prepared baking dish. Sprinkle the shredded mozzarella and additional Parmesan cheese evenly over the top.

Step 6: Prepare the Topping

In a small bowl, mix the breadcrumbs with melted butter and Parmesan cheese. Sprinkle this over the casserole for a crispy, golden topping.

Step 7: Bake the Casserole

Place the dish in the oven and bake for 25–30 minutes, or until the top is golden brown and bubbly.

Step 8: Serve and Enjoy!

Remove the casserole from the oven and let it rest for 5 minutes before serving. Garnish with fresh parsley or additional Parmesan cheese if desired. Enjoy!

Ingredient Background

Chicken: A Protein Powerhouse

Chicken breast is a fantastic source of lean protein, making it a staple in many households. It’s versatile, easy to cook, and absorbs flavors beautifully. In this casserole, chicken provides a hearty, satisfying bite that complements the creamy Alfredo sauce. Whether you use leftover rotisserie chicken, grilled, or baked chicken, it blends seamlessly into the dish.

Broccoli: A Nutrient-Rich Green

Broccoli isn’t just a filler ingredient, it’s a nutritional superstar! Packed with fiber, vitamins C and K, and antioxidants, this green veggie boosts the health benefits of your casserole. Steaming or blanching it before baking ensures it retains its bright color and slightly crisp texture. If you’re not a fan of broccoli, you can swap it for spinach, zucchini, or asparagus.

Alfredo Sauce: The Velvety Star of the Dish

Alfredo sauce is what gives this casserole its creamy, indulgent texture. Traditionally made with butter, heavy cream, and Parmesan cheese, it coats the pasta and chicken in rich, velvety goodness. While store-bought Alfredo sauce is convenient, homemade is always best since you can control the ingredients and flavor intensity.

Technique Tips for Chicken Broccoli Alfredo Casserole

Mastering a great casserole comes down to technique. Here are some expert tips to ensure your dish turns out perfect every time.

Tip 1: Cook the Pasta Al Dente

Since the casserole bakes in the oven, you don’t want your pasta to become mushy. Cook it just until al dente, meaning it still has a slight bite to it. This way, it maintains its texture even after baking in the creamy sauce.

Tip 2: Don’t Overcook the Broccoli

To keep the broccoli from becoming too soft, lightly steam or blanch it for only 2–3 minutes before adding it to the casserole. This ensures it stays vibrant and adds a slight crunch to contrast the creamy sauce.

Tip 3: Create a Crispy Topping

The secret to a golden, crispy top layer is the buttery breadcrumb topping. Mixing breadcrumbs with melted butter and Parmesan gives the casserole a slight crunch that contrasts beautifully with the creamy filling. If you prefer an extra-cheesy top, mix in some shredded mozzarella or sharp cheddar.

Alternative Presentation Ideas

While this casserole is already a showstopper, here are a few ways to serve it with a creative twist.

1. Individual Casserole Cups

Instead of baking the casserole in a large dish, portion it into individual ramekins or oven-safe bowls. This is a great way to serve it at dinner parties or make meal prepping easier. Plus, everyone gets their own mini serving with perfectly crispy edges!

2. Stuffed Peppers or Tomatoes

For a fun and unique way to enjoy this dish, stuff the Alfredo mixture into hollowed-out bell peppers or tomatoes before baking. The natural sweetness of the peppers or tomatoes balances the rich Alfredo sauce, adding a fresh twist to the dish.

3. Bread Bowl Casserole

Want to make this even more indulgent? Hollow out a large round loaf of bread, such as sourdough, and fill it with the Chicken Broccoli Alfredo mixture before baking. The crispy bread exterior and creamy interior make for an irresistible meal.

Freezing and Storing Chicken Broccoli Alfredo Casserole

This casserole is perfect for meal prep since it stores and reheats beautifully. Here’s how to keep it fresh.

1. Refrigerating Leftovers

Once cooled, store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven at 350°F for about 15 minutes until warmed through.

2. Freezing the Casserole

To freeze, prepare the casserole as usual but do not bake it yet. Cover it tightly with plastic wrap and aluminum foil, then freeze for up to 3 months. When ready to bake, thaw it in the fridge overnight and bake at 375°F for about 40–45 minutes.

3. Freezing Individual Portions

For easy grab-and-go meals, portion the casserole into freezer-safe containers. When ready to eat, simply reheat in the microwave or oven until hot and bubbly.

Healthier Twist Ideas

Want to enjoy this creamy casserole with a healthier touch? Here are some ways to lighten it up without sacrificing flavor.

1. Swap Heavy Cream for Greek Yogurt

Instead of heavy cream, use plain Greek yogurt or low-fat milk for a lighter yet still creamy Alfredo sauce. The tanginess of the yogurt adds depth to the sauce while reducing overall fat.

2. Use Whole Wheat or Chickpea Pasta

For added fiber and protein, replace regular pasta with whole wheat, chickpea, or lentil-based pasta. These alternatives are great for maintaining balanced blood sugar levels and keeping you full longer.

3. Reduce Cheese and Butter

Instead of using a full cup of cheese, reduce the amount slightly and replace it with nutritional yeast or a mix of reduced-fat cheese. You’ll still get that cheesy flavor but with fewer calories.

This casserole is perfect for all kinds of gatherings! Here’s how to make it shine for different occasions.

Serve this casserole with a side of garlic bread and a fresh green salad for a balanced meal. It’s the ultimate comfort food for a cozy family dinner.

2. Potluck or Party Dish

If you’re bringing this to a potluck, bake it in a disposable foil pan for easy transport. Sprinkle some extra cheese on top before serving to keep it looking fresh and appealing.
