This chicken and broccoli baked alfredo has saved me countless weeknight dinners when I needed something hearty that wouldn't keep me stuck in the kitchen for hours. The creamy alfredo sauce coats every piece of rigatoni while the broccoli adds that perfect pop of color and crunch. I love how the cheese gets all golden and bubbly on top, creating those crispy edges that everyone fights over. It's one of those dishes that makes your house smell amazing and brings everyone to the table without any coaxing.
My kids used to turn their noses up at anything green on their plates, but this dish changed everything. Something about that creamy sauce makes the broccoli taste like a treat instead of a chore. Now my youngest actually asks me to make "the cheesy pasta with trees" for his birthday dinner. It's become our go-to meal when we have company coming over because it looks fancy but doesn't stress me out to make.
Ingredient Breakdown
- Rigatoni pasta: Those little tubes grab onto the sauce perfectly, and they hold up well during baking without getting mushy. The ridged surface means every bite gets coated in that creamy goodness.
- Rotisserie chicken: This is my secret weapon for quick dinners. The seasoning is already done, and the meat stays juicy even after baking. I always keep one in the fridge for busy nights.
- Fresh broccoli florets: Cut them into bite-sized pieces so they cook evenly with the pasta. Fresh tastes so much better than frozen, and the bright green color makes the whole dish look more appealing.
- Alfredo sauce: I use the good stuff from the refrigerated section rather than the shelf-stable jars. It makes a noticeable difference in flavor and texture.
- Mozzarella cheese: I always shred my own because it melts smoother and doesn't have that weird coating that pre-shredded cheese has. It's worth the extra few minutes.
- Parmesan cheese: The real deal, not the powdered stuff. It adds that sharp, nutty flavor that makes this taste like restaurant quality.

Step-by-Step Instructions
- Getting the Pasta Ready:
- Fill your biggest pot with water and add enough salt to make it taste like ocean water. Bring it to a rolling boil, then add the rigatoni. Cook it for about 3-4 minutes less than what the box says for al dente. This might seem weird, but trust me on this one. The pasta keeps cooking in the oven, so starting with slightly underdone pasta prevents it from turning into mush later.
- Adding the Broccoli:
- When your pasta has about 3-4 minutes left, toss in the broccoli florets. They'll cook right along with the pasta, which saves you from dirtying another pot. The broccoli should be bright green and still have a little crunch when you drain everything together. If it gets too soft now, it'll be mushy after baking.
- Draining and Assembly:
- Drain everything really well in a colander. Give it a good shake to get rid of excess water because nobody wants a watery casserole. Dump the pasta and broccoli into a greased 9x13 baking dish and spread it out evenly. You want a nice, even layer so everything cooks at the same rate.
- Adding the Good Stuff:
- Scatter the shredded chicken all over the pasta and broccoli. Break up any big chunks so every serving gets some meat. Pour the alfredo sauce over everything, then sprinkle with salt, pepper, and garlic powder. Now comes the fun part - get your hands in there and gently mix everything together until every piece of pasta is coated in sauce.
- Cheese Layer Magic:
- Sprinkle the parmesan first, letting it fall into all the nooks and crannies. Then add the mozzarella in an even layer across the top. Don't pack it down too hard - you want it to melt and get bubbly, not form a dense layer. The cheese should cover most of the surface, but don't worry if it's not perfect.
- Baking to Perfection:
- Pop it in a 350-degree oven uncovered for about 25 minutes. You'll know it's done when the cheese is golden brown and the edges are bubbling like crazy. The middle should be hot and bubbly too, not just the edges. Let it sit for about 5 minutes before serving - this helps the sauce thicken up and makes it easier to serve.
The biggest mistake I made when I first started making this was cooking the pasta all the way through before baking it. The result was a mushy mess that nobody wanted to eat. Now I always undercook it slightly, and the texture is perfect every time. My mother-in-law taught me this trick, and it's been a game-changer for all my baked pasta dishes.
Sauce Distribution Secrets
Getting that alfredo sauce everywhere it needs to be takes a little technique. Don't just dump it all in one spot and hope for the best. Pour it in several places across the dish, then use a big spoon or clean hands to fold everything together gently. You want to see sauce coating most of the pasta, but don't overmix or you'll break the rigatoni. The sauce will spread more as it bakes, but starting with good coverage ensures every bite is creamy.
Broccoli Timing Tips
The key to perfect broccoli in this dish is all about timing. Add it too early to the pasta water, and it turns into green mush. Add it too late, and it stays too crunchy and doesn't blend well with the other flavors. I've found that adding it during the last 3-4 minutes of pasta cooking gives you that perfect crisp-tender texture. The broccoli should still have some bite when you drain it because it softens more in the oven.
Chicken Preparation Methods
Rotisserie chicken is a huge time-saver, but how you handle it makes a difference. Pull off all the skin and pick out any bones, then shred the meat into chunky pieces rather than tiny shreds. Bigger pieces give you better texture and don't disappear into the sauce. If you're using leftover grilled chicken instead, make sure it's not dried out because it will absorb some of the alfredo sauce during baking.
Cheese Quality Impact
The cheese you choose really affects how this dish turns out. Hand-shredded mozzarella melts so much better than the pre-shredded stuff because it doesn't have those anti-caking chemicals. Fresh parmesan has a completely different flavor than the powdered kind - it's sharper and more complex. The combination gives you both the stretchy melt of mozzarella and the punch of flavor from good parmesan.
Perfect Side Dishes
This rich, creamy casserole needs something light and fresh alongside it. I usually make a simple green salad with lemon vinaigrette to cut through all that cheese. Garlic bread is always a hit, though it does make the meal pretty heavy. For something lighter, steamed green beans or roasted asparagus work really well. In summer, I love serving it with a tomato and basil salad that adds some freshness and color to the plate.
Creative Variations
While this recipe is delicious as written, small changes can make it feel completely different. Sun-dried tomatoes add a Mediterranean vibe, while spinach boosts the nutrition and adds more green color. Crispy bacon pieces make it feel more indulgent, and mushrooms add an earthy flavor that works really well with the alfredo. For spice lovers, a pinch of red pepper flakes or some diced jalapeños mixed with the chicken creates a version with some heat.
Storage and Reheating
This casserole keeps really well in the fridge for up to four days, making it perfect for meal prep. Cover it tightly with plastic wrap or transfer portions to containers to keep the top from drying out. When reheating, add a splash of milk or cream to bring back that creamy texture since the sauce thickens when cold. Microwave in 30-second bursts, stirring between each, or warm it gently in the oven at 325 degrees until heated through.

- → What if I don't have rotisserie chicken?
- You can use any cooked chicken - grilled, baked, or even leftover chicken. You'll need about 3-4 cups of shredded cooked chicken.
- → Can I make this ahead of time?
- Yes! Assemble the casserole, cover, and refrigerate for up to 24 hours. Add 10-15 minutes to the baking time if cooking from cold.
- → What pasta shapes work best?
- Rigatoni is perfect, but penne, ziti, or shells also work well. Use any short pasta that holds sauce nicely.
- → How do I prevent it from drying out?
- Don't overbake, and make sure there's enough sauce to coat everything. You can cover with foil if the top browns too quickly.
- → Can I freeze leftovers?
- Absolutely! This freezes well for up to 3 months. Thaw overnight and reheat covered in a 350°F oven until heated through.
