Ingredients You’ll Need

12 ounces penne pasta: This shape holds sauces well and complements the creamy Alfredo.
3 cups chicken breasts, cooked, shredded or diced: For protein and flavor; rotisserie chicken can save time.
4 cups broccoli florets: A pop of color and nutrition; you can substitute with other veggies if desired.
2 cups mozzarella cheese, shredded, divided: Provides a creamy meltiness; feel free to use a blend of cheeses.
½ cup parmesan cheese, freshly grated: Essential for that nutty flavor; using freshly grated enhances taste.
6 tablespoons unsalted butter: Helps create the roux for the sauce; unsalted is recommended for better control of seasoning.
4 cloves garlic, minced: Adds aromatic depth; adjust according to your taste preference.
6 tablespoons all-purpose flour: This thickens the sauce; cornstarch can be a gluten-free substitute.
3 cups whole milk: For creaminess; you could use low-fat milk but may sacrifice richness.
1 cup heavy cream: This luxury ingredient elevates the creaminess; light cream will work as a lighter option.
1 teaspoon kosher salt: Essential for seasoning; adjust based on your dietary needs.
½ teaspoon black pepper: For a bit of heat; feel free to use white pepper for a milder taste.
½ teaspoon garlic powder: Enhances the garlic flavor; optional but delightful.
¼ teaspoon onion powder: Adds depth; you can skip this if you prefer.
Pinch of nutmeg: A unique touch that complements the creamy sauce; too much can overwhelm, so use lightly.
1 cup parmesan cheese, freshly grated: For both flavor and topping; freshly grated melts better.
Remaining 1 cup mozzarella cheese: For topping, to ensure a nice, gooey finish.
¼ cup parmesan cheese: Additional topping for an extra cheesy delight.
½ cup panko breadcrumbs: Creates a crispy topping; regular breadcrumbs work but won’t be as crispy.
1 tablespoon melted butter: Binds the breadcrumbs together for a perfectly crisp topping.

How to Make Chicken Broccoli Alfredo

Preheat Your Oven: Set the oven to 375°F, allowing it to reach the right temperature while you prepare your ingredients.
Cook the Pasta: In a large pot of salted boiling water, add 12 ounces of penne pasta. Cook until just shy of al dente, about 1 minute less than package instructions. During the last 2 minutes of cooking, drop in 4 cups of broccoli florets to blanch. Drain the pasta and broccoli well.
Make the Alfredo Sauce: In a large saucepan, melt 6 tablespoons of unsalted butter over medium heat. Add 4 cloves of minced garlic and sauté for about 30 seconds until fragrant. Then, whisk in 6 tablespoons of all-purpose flour and cook for 1 minute. Gradually whisk in 3 cups of whole milk and 1 cup of heavy cream, stirring constantly. Simmer for 3 to 5 minutes until the sauce thickens. Season with 1 teaspoon of kosher salt, ½ teaspoon of black pepper, ½ teaspoon of garlic powder, ¼ teaspoon of onion powder, and a pinch of nutmeg. Off the heat, stir in 1 cup of freshly grated Parmesan cheese until melted and smooth.
Combine Everything: In a large mixing bowl, toss together the cooked pasta, broccoli, 3 cups of shredded chicken, 1 cup of shredded mozzarella cheese, and ½ cup of Parmesan cheese with the Alfredo sauce until well-coated. Transfer the mixture to a greased 9×13-inch baking dish, spreading it evenly to avoid any dry patches.
Add Toppings: Sprinkle the remaining 1 cup of mozzarella cheese and ¼ cup of Parmesan evenly over the top. For that extra crispy topping, combine ½ cup of panko breadcrumbs with 1 tablespoon of melted butter, then sprinkle over the cheese layer.
Bake to Perfection: Bake uncovered for about 25 to 30 minutes, or until the casserole is hot and bubbling with a golden-brown cheese layer. For additional browning, broil for 1 to 2 minutes just before serving, keeping a close eye on it.

Storing & Reheating

If you have any leftovers (which is rare because it’s so delicious!), allow the Chicken Broccoli Alfredo to cool before transferring it to an airtight container. It will keep in the refrigerator for up to 4 days. For longer storage, consider freezing it; it should maintain quality for up to 3 months. When you’re ready to enjoy the leftovers, simply reheat in the oven at 350°F for about 20 minutes or until heated through. You might find that the creamy texture changes slightly, so adding a splash of milk during reheating can refresh the sauce.

Chef’s Helpful Tips

Keep your chicken moist by not overcooking it while making the sauce; if using rotisserie chicken, add it at the end to warm through.
Always whisk your flour well to avoid lumps in the sauce; patience is key when adding the milk and cream.
For added depth of flavor, let your sauce simmer a bit longer, but keep stirring so it doesn’t stick or burn.
Consider using half-and-half instead of heavy cream for a lighter version, but the flavor will be less rich.
If you make this ahead of time, bake it just before serving for optimal freshness; bake at the same temperature, adding a few extra minutes if needed.

Chicken Broccoli Alfredo is not just a meal; it’s an experience filled with warmth and family togetherness. This rich, creamy dish will undoubtedly impress your dinner guests and is an easy way to bring smiles to your loved ones’ faces. Don’t hesitate to experiment with different veggies, or even use different pasta shapes; this recipe is versatile and forgiving! I can’t wait for you to enjoy it as much as I do.

Absolutely! You can prepare the entire dish, assemble it, and store it in the fridge for up to 24 hours before baking. Just cover it tightly with plastic wrap or a lid to keep it fresh.

What can I use instead of heavy cream?

If you’re looking for a lighter option, you can substitute heavy cream with half-and-half or even whole milk. Keep in mind that this will result in a creamier but slightly less rich sauce.
