Ingredients You’ll Need
This dish is surprisingly straightforward, relying on simple but carefully chosen ingredients that each play a vital role in creating the creamy texture, rich flavor, and beautiful appearance. Every component, from the pasta to the cheese to the crispy topping, works together to build layers of deliciousness.
- 12 ounces pasta (penne or rotini): The perfect shape for holding onto the creamy sauce.
- 2 cups cooked chicken, shredded or cubed: Adds heartiness and protein.
- 2 cups broccoli florets, blanched or steamed: Brings color, crunch, and nutrients.
- 2 tablespoons butter: Essential for sautéing and creating the roux base of the sauce.
- 3 cloves garlic, minced: Infuses the dish with aromatic depth.
- 2 tablespoons all-purpose flour: Thickens the Alfredo sauce to creamy perfection.
- 1 3/4 cups milk: The liquid base for a smooth, velvety sauce.
- 1/2 cup heavy cream: Elevates the sauce’s richness and silkiness.
- 3/4 cup grated Parmesan cheese: Adds a sharp, nutty flavor throughout.
- 1 cup shredded mozzarella cheese: Melts beautifully for gooey, cheesy pulls.
- 1/2 teaspoon salt: Enhances all the flavors harmoniously.
- 1/4 teaspoon black pepper: A subtle kick to balance richness.
- 1/4 teaspoon garlic powder: Boosts the garlicky goodness in the sauce.
- For the Crispy Topping: 3/4 cup panko breadcrumbs; 2 tablespoons butter, melted; 1/4 cup grated Parmesan cheese; 1/2 teaspoon Italian seasoning – ensures a golden, crunchy finish that contrasts beautifully with the creamy base.
How to Make Chicken Broccoli Alfredo Bake with a Crispy Topping Recipe
Step 1: Prepare the Pasta and Broccoli
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish to prevent sticking. Cook the pasta in salted boiling water until it’s perfectly al dente – tender but with a slight bite. Meanwhile, blanch or steam the broccoli florets just until vibrant green and tender-crisp, so they’ll keep a bit of texture after baking.
Step 2: Make the Alfredo Sauce
In a large saucepan, melt butter over medium heat and gently sauté the minced garlic until fragrant, about one minute. Stir in flour to make a roux, cooking for another 1 to 2 minutes to erase any raw flour taste. Gradually whisk in the milk and cream until smooth, letting it simmer for 3 to 5 minutes until it thickens softly. Stir in Parmesan, mozzarella, salt, pepper, and garlic powder until the sauce becomes luxuriously smooth and creamy.
Step 3: Combine Everything
In a large bowl, toss together the cooked pasta, shredded chicken, broccoli, and Alfredo sauce, ensuring every piece is well coated. Then, transfer this delicious mixture evenly into your prepared baking dish, setting the stage for a bubbling, cheesy bake.
Step 4: Prepare the Crispy Topping and Bake
Mix panko breadcrumbs with melted butter, Parmesan cheese, and Italian seasoning in a small bowl until crumbs are evenly coated. Sprinkle this mixture generously over the top of the casserole. Bake for 20 to 25 minutes or until the casserole is bubbly and the topping has turned a beautiful golden brown. Let it rest for 5 minutes before serving to allow everything to set and intensify in flavor.
How to Serve Chicken Broccoli Alfredo Bake with a Crispy Topping Recipe

Garnishes
A sprinkle of fresh chopped parsley or basil adds a pop of color and freshness that cuts through the richness. You can also grate a little extra Parmesan on top just before serving for added cheesiness and flair.
Side Dishes
This hearty bake pairs wonderfully with a light mixed green salad tossed in a tangy vinaigrette or some roasted garlic bread to soak up any leftover sauce. Steamed or roasted veggies on the side bring balance and extra nutrients to the meal.
Creative Ways to Present
For a fun twist, serve individual portions in small ramekins or mini cast-iron skillets topped with the crispy crumbs right out of the oven. It’s perfect for dinner parties or family gatherings where everyone can enjoy their own personal cheesy, crunchy masterpiece.
Make Ahead and Storage
Storing Leftovers
Store any leftover Chicken Broccoli Alfredo Bake with a Crispy Topping Recipe in an airtight container in the refrigerator for up to 3 days. The flavors often deepen overnight, making the second serving just as delightful.
Freezing
You can freeze the casserole before baking by assembling it in a freezer-safe dish and covering tightly with foil and plastic wrap. It will keep well for up to 2 months. When ready, bake straight from frozen—just add extra time to ensure it’s heated through and bubbly.
Reheating
Reheat leftovers in the oven at 350°F (175°C) to preserve the crispy topping, covering loosely with foil if needed to prevent burning. Alternatively, microwave individual portions, but the topping might lose a bit of its crispness this way.
FAQs
Can I use a different type of pasta for this Chicken Broccoli Alfredo Bake with a Crispy Topping Recipe?
Absolutely! While penne and rotini work wonderfully for holding onto the sauce, any short pasta like fusilli, rigatoni, or farfalle will also be delicious. Just avoid delicate pastas that may get mushy during baking.
Is it possible to make this recipe vegetarian?
Yes! Simply omit the chicken and add hearty vegetables like mushrooms, cauliflower, or even artichokes. Consider adding extra cheese or beans for protein to keep it satisfying.
Can I prepare the sauce ahead of time?
Definitely. Prepare the Alfredo sauce up to a day in advance and store it in the fridge. Warm it gently before mixing with pasta and other ingredients to keep it smooth and creamy.
What can I do if I don’t have panko breadcrumbs for the topping?
You can substitute regular breadcrumbs or even crushed crackers for the topping. Panko offers extra crispness, but other options will still give you a nice crunch.
How do I add a little spicy kick to the bake?
Try sprinkling in red pepper flakes into the Alfredo sauce or mixing them with the breadcrumb topping. It adds just the right amount of heat without overpowering the dish.
