Chicken and Broccoli Alfredo Bake is a creamy, comforting dish that brings together tender chicken, fresh broccoli, and a rich Alfredo sauce all baked to bubbly perfection. The combination of gooey cheese, tender pasta, and those little green broccoli florets makes it a meal that feels warm and satisfying every time.
I love making this dish on a busy weeknight because it’s an easy way to get a good mix of protein and veggies, all in one pan. The Alfredo sauce is smooth and cheesy without being too heavy, and the chicken pieces add just the right amount of heartiness. Plus, the broccoli adds a pop of color and some fresh goodness that helps balance everything out.
One of my favorite things about this bake is how it feels like a cozy, homemade meal that everyone at the table enjoys. I like to sprinkle a little extra cheese on top before baking to get that golden, melty crust that everyone fights over. This dish is excellent served with a simple green salad or some garlic bread to soak up any leftover sauce. It’s the kind of meal that’s great for sharing and makes your kitchen smell amazing while it’s baking.

Key Ingredients & Substitutions for Chicken and Broccoli Alfredo Bake
Pasta: Rigatoni or penne hold sauce well because they have hollow shapes. No rigatoni? Use elbow macaroni or ziti. Just pick a sturdy pasta that can handle baking without getting mushy.
Broccoli: Fresh broccoli is best for a bright flavor and slight crunch. Steaming or blanching before baking helps keep it tender but not soggy. You can swap for cauliflower florets if you want a milder taste.
Chicken: Cooked chicken breast is the heart of this bake. Rotisserie chicken works great for ease and flavor. For a lighter version, use turkey breast or skip for a vegetarian option and add mushrooms or tofu.
Alfredo Sauce: Creamy Alfredo sauce makes this dish rich and smooth. Use store-bought for convenience or homemade for freshness. If you want a dairy-free choice, try a cashew cream sauce or non-dairy Alfredo alternatives.
Cheese: Mozzarella adds melty texture, Parmesan boosts flavor with a nutty sharpness. If you’re short on Parmesan, Pecorino or Asiago make good stand-ins. For cheese-free, nutritional yeast can add a cheesy flavor.
How Do I Keep Broccoli Bright and Tender in the Bake?
Broccoli can get mushy or lose color if not handled right. Here’s how to keep it fresh-looking and tasty:
- Blanch or Steam Briefly: Cook broccoli florets in boiling water for just 2 minutes or steam until bright green and slightly tender.
- Shock in Ice Water: Place cooked broccoli in ice water right after to stop cooking and keep the green color vivid.
- Drain Well: Make sure broccoli is dry before mixing it into the pasta to avoid watering down the sauce.
- Add Later: Mix broccoli with the other ingredients just before baking to prevent overcooking during the bake time.
Equipment You’ll Need
- Large pot – for boiling the pasta perfectly al dente.
- Steamer basket or colander – to steam or blanch the broccoli easily.
- Skillet or frying pan – to cook and brown the chicken pieces with garlic.
- Mixing bowl – to toss pasta, chicken, broccoli, and sauce together smoothly.
- 9×13 inch baking dish – roomy enough for the bake to cook evenly and get a golden top.
- Wooden spoon or spatula – for mixing ingredients without breaking pasta.
Flavor Variations & Add-Ins
- Swap chicken for cooked shrimp for a seafood twist that cooks quickly and pairs well with Alfredo sauce.
- Add sun-dried tomatoes for a tangy punch and deeper color contrast.
- Mix in sautéed mushrooms to bring earthiness and extra texture.
- Stir in red pepper flakes or a pinch of nutmeg to give the dish a subtle warming spice.
How to Make Chicken and Broccoli Alfredo Bake?
Ingredients You’ll Need:
Main Ingredients:
- 12 oz rigatoni or penne pasta
- 2 cups broccoli florets, steamed or blanched
- 2 cups cooked chicken breast, cut into bite-sized pieces
- 2 cups Alfredo sauce (store-bought or homemade)
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 2 tbsp olive oil
- 2 cloves garlic, minced
- Salt and black pepper to taste
- ½ tsp Italian seasoning or dried oregano (optional)
- ¼ cup breadcrumbs (optional for topping)
How Much Time Will You Need?
This dish will take about 10 minutes to prep, 15 minutes to cook the pasta and chicken, and 20-25 minutes baking time. In total, plan for approximately 45-50 minutes from start to finish, making it a perfect weeknight meal.
Step-by-Step Instructions:
1. Prepare the Oven and Pasta:
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with a little olive oil or cooking spray. Start cooking the pasta in a large pot of salted boiling water until al dente, usually 1-2 minutes less than the package suggests. Drain and set aside.
2. Cook the Chicken:
If your chicken isn’t cooked already, heat olive oil in a skillet over medium heat. Add minced garlic and sauté for about 1 minute until it smells amazing. Add the chicken pieces, season with salt, pepper, and Italian seasoning if using, and cook until they’re fully cooked and lightly browned. Remove from heat.
3. Mix Everything Together:
In a large mixing bowl, combine the cooked pasta, chicken, broccoli florets, and Alfredo sauce. Toss everything together gently until the pasta and chicken are all covered with creamy sauce.
4. Assemble and Bake:
Pour the mixture evenly into your prepared baking dish. Sprinkle the shredded mozzarella and Parmesan cheese evenly on top. If you like a crunchy topping, sprinkle breadcrumbs over the cheese layer. Place it in the oven and bake for 20-25 minutes, or until the cheese has melted, is bubbly, and the top is a lovely golden brown.
5. Rest and Serve:
When done, take the bake out of the oven and let it rest for 5 minutes. This gives it time to set slightly and helps you serve nice slices. Enjoy this warm, creamy, and cheesy Chicken and Broccoli Alfredo Bake as a comforting meal for your family or friends!
Can I Use Frozen Broccoli Instead of Fresh?
Yes! Just thaw and drain the frozen broccoli well to avoid extra moisture in the bake. You can steam or blanch frozen broccoli briefly to keep its texture before mixing it in.
Can I Make This Ahead of Time?
Absolutely! Prepare the entire dish up to the baking step, cover tightly, and refrigerate for up to 24 hours. When ready, bake straight from the fridge, adding a few extra minutes if needed.
How Should I Store Leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave until warmed through, stirring halfway for even heating.
Can I Substitute Alfredo Sauce with Something Else?
If you don’t have Alfredo sauce, you can use a creamy cheese sauce, béchamel, or even a mix of cream and grated Parmesan. Just make sure it’s rich enough to coat the pasta well.
