This Chicken and Broccoli Alfredo Bake is a creamy, comforting dish filled with tender chicken pieces, bright green broccoli florets, and plenty of cheesy Alfredo sauce baked to bubbly perfection. It’s the kind of meal that brings cozy vibes and fills the kitchen with a wonderful aroma that makes everyone’s mouth water.
I love making this bake because it’s simple to put together, and it always feels like a special dinner even on a busy weeknight. The combination of the creamy sauce with the soft chicken and just-right broccoli texture really hits the spot for me. Plus, it’s great for leftovers — the flavors seem to deepen overnight, which is always a win.
My favorite way to serve this is straight from the oven with a side of crusty bread to soak up all the sauce. It’s one of those meals that’s easy enough for a family dinner but special enough to share with friends. If you’re like me and appreciate simple comfort food, this Alfredo bake might just become a fast favorite in your house too.
Key Ingredients & Substitutions
Chicken breasts: I like using cooked chicken breast for a lean protein that stays tender. You can swap this with rotisserie chicken or cooked thighs for juicier bites.
Broccoli florets: Fresh broccoli adds a nice crunch, but frozen works great for convenience. Just drain well to avoid extra water in the bake.
Pasta: Rotini holds sauce well due to its shape, but penne or rigatoni are good alternatives. Cook pasta just until al dente since it bakes later.
Alfredo sauce: Store-bought saves time and tastes delicious, but homemade Alfredo makes this dish extra rich. Use heavy cream and Parmesan for that creamy texture.
Cheese: Mozzarella melts beautifully for stretchiness, while Parmesan adds sharp flavor. Feel free to mix in some Fontina or Gruyère for extra depth.
How Do You Get the Perfectly Creamy Alfredo Sauce Without It Breaking?
Making or heating Alfredo sauce can be tricky as it can split or become grainy if overheated. Here’s how to keep it smooth and creamy:
- Warm the sauce slowly over low to medium heat – avoid boiling it.
- Stir frequently to keep the sauce from sticking or forming a skin.
- If making from scratch, add cheese off the heat to prevent overcooking and clumping.
- Use fresh cream or half-and-half rather than milk for a richer sauce.
- Adding a small bit of pasta water can help the sauce coat pasta better and stay smooth.
By taking these gentle steps, your Alfredo sauce will stay velvety and delicious throughout baking.
Equipment You’ll Need
- Large pot – perfect for boiling pasta and broccoli together to save time and dishes.
- Skillet or frying pan – great for warming cooked chicken and sautéing garlic to boost flavor.
- Mixing bowl – you’ll mix the pasta, sauce, chicken, and broccoli here for even coating.
- 9×13-inch baking dish – roomy enough for layering and baking your creamy Alfredo casserole.
- Wooden spoon or spatula – handy for stirring without scratching your cookware.
Flavor Variations & Add-Ins
- Swap chicken for cooked shrimp to give the bake a fresh, seafood twist.
- Add sautéed mushrooms or sun-dried tomatoes for an earthy or tangy kick that pairs well with creamy sauce.
- Mix in cooked spinach or kale for an extra boost of greens and nutrients.
- Use a blend of mozzarella and sharp cheddar cheeses for a richer, more flavorful cheese layer.
How to Make Chicken and Broccoli Alfredo Bake
Ingredients You’ll Need:
Main Ingredients:
- 2 cups rotini pasta (or penne)
- 2 cups broccoli florets, fresh or frozen
- 2 large chicken breasts, cooked and sliced or cubed
- 2 cups Alfredo sauce (store-bought or homemade)
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare, 15 minutes to cook the pasta and broccoli, and about 20-25 minutes to bake. In total, plan for roughly 45 minutes from start to finish, including a short resting time before serving.
Step-by-Step Instructions:
1. Preheat Oven and Prepare Dish:
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
2. Cook Pasta and Broccoli:
Bring a large pot of salted water to a boil. Cook the pasta according to the package instructions until al dente. About 2-3 minutes before the pasta is done, add the broccoli florets to the boiling water with the pasta. Once both are cooked, drain them together and set aside.
3. Sauté Garlic and Heat Chicken:
While the pasta cooks, heat olive oil or butter in a skillet over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant. Then stir in the cooked chicken pieces and season with salt and pepper. Heat until warmed through.
4. Mix Ingredients for the Bake:
In a large bowl, combine the cooked pasta and broccoli, sautéed chicken and garlic, Alfredo sauce, half of the mozzarella, half of the Parmesan, and chopped parsley if using. Mix thoroughly so everything is coated evenly.
5. Assemble and Bake:
Transfer the mixture into your prepared baking dish. Sprinkle the remaining mozzarella and Parmesan cheeses evenly over the top. Bake uncovered for 20-25 minutes until the cheese is melted, bubbly, and golden brown.
6. Rest and Serve:
Remove the dish from the oven and let it rest for 5 minutes before serving. Garnish with additional parsley if you like. Serve warm with crusty bread or a fresh salad for a comforting and tasty meal.
Can I Use Frozen Broccoli for This Recipe?
Yes! Frozen broccoli works perfectly. Just make sure to thaw and drain it well before mixing to avoid excess water making the bake too watery.
How Can I Make This Recipe Ahead of Time?
You can prepare the entire casserole up to step 6, cover it tightly, and refrigerate for up to 24 hours. When ready, bake it a few extra minutes until hot and bubbly.
Can I Substitute the Chicken?
Absolutely! Use cooked turkey, ham, or even cooked shrimp to change up the protein while keeping the creamy Alfredo flavor.
How Should Leftovers Be Stored?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave, adding a splash of cream or milk if needed to bring back creaminess.
