- Cooked chicken (2 cups, shredded or diced): Use rotisserie chicken for convenience or leftover roast for extra flavor.
- Broccoli florets (2 cups, steamed or blanched): Fresh or frozen both work—just make sure they’re bright green and crisp-tender.
- Penne or rotini pasta (8 ounces, cooked and drained): These shapes hold onto the sauce perfectly, but any short pasta will do.
- Butter (2 tablespoons): Adds richness to the Alfredo and helps the sauce come together beautifully.
- Garlic (2 cloves, minced): A must for that classic Alfredo aroma and flavor.
- All-purpose flour (2 tablespoons): Thickens the sauce so it clings to every bite of pasta and chicken.
- Whole milk (1 1/2 cups): Gives the sauce a creamy, luscious base.
- Heavy cream (1 cup): Adds extra silkiness and richness that makes this dish truly indulgent.
- Grated Parmesan cheese (1 cup): The star of any Alfredo, bringing salty, nutty flavor.
- Salt (1/2 teaspoon): Essential for balancing the flavors.
- Black pepper (1/4 teaspoon): Just enough to add a touch of warmth.
- Garlic powder (1/4 teaspoon): Layers in even more savory depth.
- Shredded mozzarella cheese (1/2 cup): Melts into a gooey, irresistible topping.
- Panko breadcrumbs (1/2 cup): Delivers that signature crispy topping you’ll crave with every forkful.
- Olive oil (1 tablespoon): Helps brown the breadcrumbs to golden perfection.
- Grated Parmesan cheese (2 tablespoons, for topping): Adds a final punch of flavor to the crunchy crust.
How to Make Chicken Broccoli Alfredo Bake with a Crispy Topping
Step 1: Prep Your Ingredients
Before you start cooking, get everything ready—steam or blanch your broccoli, cook and drain the pasta, and shred or dice your chicken. Having everything prepped means the creamy Alfredo comes together in a flash and nothing gets overcooked.
Step 2: Make the Creamy Alfredo Sauce
In a medium saucepan over medium heat, melt the butter, then add the minced garlic and sauté just until fragrant. Stir in the flour and cook for about a minute to get rid of any raw taste. Slowly whisk in the milk and cream, stirring constantly until the sauce is smooth and just starting to thicken. Now’s the time to add the Parmesan, salt, pepper, and garlic powder—keep stirring until everything is melty and luscious.
Step 3: Combine and Assemble
Grab a large bowl and toss together your cooked pasta, juicy chicken, bright broccoli, and every drop of that dreamy Alfredo sauce. Mix it well so every piece is coated, then transfer it all to a greased 9×13-inch baking dish. Sprinkle the mozzarella cheese evenly over the top for gooey, cheesy pockets in every bite.
Step 4: Add the Crispy Topping
In a small bowl, combine the panko breadcrumbs, olive oil, and the extra two tablespoons of grated Parmesan. Toss until the crumbs are coated and then sprinkle the mixture evenly over your casserole. This step is what sets the Chicken Broccoli Alfredo Bake with a Crispy Topping apart—get ready for that golden, crackly finish!
Step 5: Bake to Perfection
Pop your dish in a preheated 375°F oven and bake, uncovered, for 20 to 25 minutes. You’re looking for bubbling edges and a deeply golden, crispy top. Let it rest for about 5 minutes out of the oven so everything can set up and slice beautifully.
How to Serve Chicken Broccoli Alfredo Bake with a Crispy Topping

Garnishes
A sprinkle of chopped fresh parsley or basil wakes up the flavors and adds a fresh pop of color. For a little zing, try a dusting of red pepper flakes or a squeeze of lemon juice just before serving. It’s all about those finishing touches that make Chicken Broccoli Alfredo Bake with a Crispy Topping feel restaurant-worthy at home.
Side Dishes
This bake is hearty enough to stand on its own, but it’s even better with a crisp green salad tossed in a light vinaigrette, or some garlic bread for soaking up every last bit of creamy sauce. Roasted vegetables or steamed green beans also make simple, colorful companions.
Creative Ways to Present
For a dinner party, spoon the Chicken Broccoli Alfredo Bake with a Crispy Topping into individual ramekins for a personal touch. Or, serve it family-style straight from the baking dish, letting everyone dig in for seconds. You can even scoop leftovers into a thermos for a comforting lunch on the go!
Make Ahead and Storage
Storing Leftovers
Store leftover Chicken Broccoli Alfredo Bake with a Crispy Topping in an airtight container in the fridge for up to three days. The flavors meld together even more overnight, making for a delicious next-day lunch or dinner.
Freezing
This casserole freezes beautifully! Assemble the dish up to the point of baking, then cover tightly with foil and freeze for up to two months. When you’re ready to eat, thaw overnight in the fridge before baking as directed—just add a few extra minutes to the bake time if it’s still a bit cold in the center.
Reheating
To reheat, cover with foil and warm in a 350°F oven until hot throughout, about 15-20 minutes. For the best crispy topping, remove the foil for the last few minutes. You can also microwave individual servings, though the topping will be less crunchy.

- Make Alfredo Sauce: In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Stir in 2 tablespoons of all-purpose flour and cook for 1 minute to form a roux. Slowly whisk in 1 1/2 cups whole milk and 1 cup heavy cream until smooth.
