The Key to the Creamiest Alfredo Sauce
The heart of this Chicken and Broccoli Alfredo Bake is the sauce. A great homemade Alfredo is what separates a good pasta bake from a truly memorable one. The secret is using good quality, simple ingredients. We use real butter, fresh garlic, heavy cream, and most importantly, freshly grated Parmesan cheese. Using a block of Parmesan and grating it yourself ensures the cheese melts smoothly into the sauce without becoming grainy or oily. It takes just a few extra minutes and makes all the difference.
Ingredients You’ll Need
Before you start, gather these simple ingredients. Exact measurements are in the recipe card below.
- Pasta: Penne is our top choice for its ability to hold the creamy sauce, but ziti or rotini work wonderfully too.
- Boneless, Skinless Chicken Breasts: Cut into bite-sized pieces for even cooking and easy eating.
- Broccoli Florets: You can use fresh or frozen. We’ll blanch them briefly to ensure they are perfectly tender-crisp.
- Butter: The rich base for our Alfredo sauce. Unsalted is best so you can control the seasoning.
- Garlic: Freshly minced garlic is a must for the best flavor.
- Heavy Cream: This creates the luxuriously creamy texture of the sauce.
- Parmesan Cheese: Freshly grated is non-negotiable for a smooth, velvety sauce.
- Mozzarella Cheese: For that irresistible, bubbly, and golden-brown topping.
- Seasoning: Salt, black pepper, and a pinch of nutmeg to enhance the creamy flavors.

Step-by-Step Instructions
Follow these simple steps to create the perfect bake. We’ll walk you through it from start to finish.
1. Prepare the Pasta and Broccoli
Start by bringing a large pot of salted water to a boil. Cook your pasta according to package directions until it’s just shy of al dente—it will finish cooking in the oven. In the last 2-3 minutes of cooking, add the broccoli florets to the pot with the pasta. This quick blanching is all they need. Drain everything well and set aside.
2. Cook the Chicken
While the pasta is cooking, heat a large skillet over medium-high heat. Season your chicken pieces with salt and pepper. Add a touch of olive oil to the skillet and cook the chicken until it’s golden brown and cooked through. Remove the chicken from the skillet and set it aside.
3. Make the Homemade Alfredo Sauce
In the same skillet, melt the butter over medium heat. Add the minced garlic and cook for about 30 seconds, until fragrant. Slowly whisk in the heavy cream and bring it to a gentle simmer. Let it cook for 3-4 minutes, allowing it to thicken slightly. Remove the skillet from the heat and gradually stir in the grated Parmesan cheese until the sauce is smooth. Season with salt, pepper, and a pinch of nutmeg.
4. Assemble and Bake the Casserole
Preheat your oven to 375°F (190°C). In a large bowl, combine the cooked pasta, broccoli, and chicken. Pour the homemade Alfredo sauce over the mixture and stir gently until everything is evenly coated. Transfer the mixture to a 9×13-inch baking dish. Sprinkle the shredded mozzarella cheese evenly over the top. Bake for 20-25 minutes, or until the sauce is bubbly and the cheese is melted and golden brown.
Tips for the Perfect Chicken and Broccoli Alfredo Bake
- Don’t Overcook the Pasta: Cooking the pasta to just under al dente is crucial. It will absorb some of the sauce and finish cooking in the oven without becoming mushy.
- Shred Your Own Cheese: Pre-shredded cheeses are often coated with anti-caking agents that can prevent them from melting smoothly. Grating your own Parmesan and mozzarella will give you the best results.
- Get a Golden Top: For an extra-bubbly, browned cheese topping, you can switch the oven to broil for the last 1-2 minutes of cooking. Keep a close eye on it to prevent burning!
- Let it Rest: After pulling the bake from the oven, let it rest for 5-10 minutes. This allows the sauce to set up and thicken slightly, making it easier to serve.
Delicious Variations to Try
Want to switch things up? This recipe is incredibly versatile. Try one of these delicious variations:
- Add Bacon: For a salty, savory kick, add some cooked, crumbled bacon to the mixture before baking.
- Spice it Up: A pinch of red pepper flakes in the Alfredo sauce will add a gentle, warming heat.
- Change the Veggies: Not a fan of broccoli? Sautéed mushrooms, spinach, or sun-dried tomatoes are excellent additions.
- Different Cheeses: Try a blend of mozzarella, provolone, and asiago for a more complex and cheesy flavor.
What to Serve with Your Bake
This Chicken and Broccoli Alfredo Bake is a hearty meal on its own, but it pairs beautifully with a few simple sides. A crisp green salad with a light vinaigrette can cut through the richness of the sauce. For a truly comforting experience, serve it alongside some crusty homemade tomato basil bread to soak up every last drop of the delicious Alfredo.
Storage, Freezing, and Reheating Instructions
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. The flavors often meld together and taste even better the next day.
Freezing the Bake
This casserole freezes well! You can freeze it before or after baking. To freeze before baking, assemble the casserole completely, cover it tightly with both plastic wrap and foil, and freeze for up to 3 months. To bake from frozen, remove the plastic wrap, cover with foil, and bake at 375°F for about an hour, then uncover and bake for another 15-20 minutes until bubbly.
Reheating for Best Results
To reheat, you can place individual portions in the microwave until heated through. For larger portions, place the casserole dish back in a 350°F oven, covered with foil, for about 20 minutes or until it’s hot and bubbly.
Frequently Asked Questions (FAQ)
Yes, you can use frozen broccoli. We recommend adding it directly to the boiling pasta water during the last 2-3 minutes of cooking, just as you would with fresh broccoli. This thaws and cooks it perfectly.
The key is to use freshly grated Parmesan cheese and to add it off the heat. Melt your butter, sauté garlic, and simmer the heavy cream to thicken it slightly. Then, remove the pan from the heat *before* stirring in the Parmesan. This prevents the cheese from overheating and separating, ensuring a smooth, creamy sauce.
Boneless, skinless chicken breasts are the best choice for this recipe as they are lean and cook quickly. Cut them into uniform, bite-sized pieces to ensure they are tender and evenly distributed throughout the casserole.
Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, you can use a microwave for individual portions or place the casserole in a 350°F oven, covered with foil, for about 20 minutes until heated through.
Absolutely! You can assemble the entire casserole without baking it, then cover and refrigerate for up to 24 hours. When you’re ready to eat, just bake as directed, adding about 10-15 minutes to the cooking time since it will be cold.
