This creamy baked pasta combines tender chicken breast, fresh broccoli florets, and a rich Alfredo sauce with melted mozzarella and Parmesan cheese. Cook penne al dente, steam the broccoli, then layer everything together in a baking dish with the chicken and sauce. Top with cheese and bake until golden and bubbly. Perfect for weeknight dinners, it comes together in just 55 minutes total and serves six generously.

The evening my furnace broke down in the middle of winter led to the creation of our family's favorite comfort meal. With the temperature dropping and repair service hours away, I needed something that would fill the kitchen with warmth and fill our bellies with something substantial. Rummaging through my pantry and refrigerator, I pulled out pasta, chicken, and a jar of Alfredo sauce that would become this now-cherished Chicken Alfredo Bake.

Last December, when my sister announced her surprise visit with her three kids, this casserole saved my sanity. The kitchen filled with laughter as I taught my niece how to test pasta for that perfect al dente bite while her brothers argued over who would get the corner piece with extra cheese. Their mom looked at me with such gratitude as we all gathered around the steaming dish, momentarily forgetting the chaos of the day.

Ingredients

  • Penne or Rigatoni Pasta: The tubular shapes trap little pockets of sauce inside, making every bite creamy and delicious.
  • Broccoli Florets: I discovered that blanching them for just 2-3 minutes preserves that bright green color and gives them the perfect tenderness without becoming mushy.
  • Alfredo Sauce: While homemade is divine, Ive found that stirring a bit of milk into a good quality store-bought version creates nearly the same luxurious texture when youre pressed for time.
  • Mozzarella and Parmesan Cheese: The combination of these two creates the ultimate cheese pull when you serve it hot from the oven.

Instructions

Prep Your Elements:
Preheat your oven to 375°F and cook your pasta just shy of al dente, as it will continue cooking in the oven. Trust me on this - slightly undercooked pasta now means perfect texture later.
Create Your Base:
The magic happens when you melt butter and sauté that minced garlic until your kitchen smells like an Italian restaurant. Add your chicken, vibrant green broccoli, and creamy Alfredo mixture, letting all those flavors get friendly with each other.
Assemble Your Masterpiece:
Fold in your pasta until every piece is coated in that velvety sauce. Your spoon will make that satisfying sound as it moves through the creamy mixture.
Cheese It Up:
Transfer everything to your baking dish and blanket it with that generous layer of cheeses. Watch how they melt together into a golden canopy that will make everyone gather around the oven window.
Bake to Perfection:
Let it bubble away for about 20-25 minutes until that cheese top turns into a beautiful golden landscape with little browned peaks. The hardest part is waiting those 5 minutes before serving, as the aromas fill your home.

My teenage son, who typically communicates in grunts and single-word responses, took his first bite of this Chicken Alfredo Bake and launched into a detailed review that had us all staring in amazement. He described the contrast between the crispy cheese top and creamy interior with such enthusiasm that we couldnt help but laugh. Ever since, making this dish has been our unspoken way of opening communication channels when hes had a rough week at school.

Make-Ahead Magic

One Sunday afternoon, fighting a mild cold and lacking energy, I assembled this entire dish, covered it with foil, and refrigerated it before the baking step. The next evening, I simply popped it in the oven while helping with homework, and dinner materialized as if Id spent hours cooking that day. The flavors had actually deepened overnight, creating an even more delicious result than usual.

Customization Corner

My vegetarian friend Claire inspired a mushroom version that converted even my meat-loving husband. I sautéed a mix of cremini and shiitake mushrooms until golden and slightly crispy, then folded them in place of the chicken. The earthy depth they brought to the dish created an entirely new experience that we now rotate into our regular meal plans.

Serving Suggestions

During our neighborhood potluck last summer, I learned that this bake transitions beautifully from winter comfort food to year-round crowd-pleaser when paired thoughtfully. The contrast of temperatures and textures creates a completely balanced meal experience that satisfies every palate at the table.

  • A simple arugula salad with lemon vinaigrette cuts through the richness perfectly, adding a peppery freshness.
  • For unexpected delight, serve with roasted cherry tomatoes that burst with sweet acidity against the creamy pasta.
  • Warm, crusty bread is non-negotiable for soaking up every last drop of that sauce.

Recipe Questions & Answers

Yes, frozen broccoli works perfectly in this dish. Thaw it first or use it frozen—just adjust steaming time slightly if needed. The final baking will ensure it cooks through completely.

Penne or rigatoni are ideal because their shapes hold the creamy sauce well. You can also use fettuccine or any short pasta that captures the Alfredo coating nicely.

Absolutely. Assemble the entire dish in the baking dish, cover with plastic wrap, and refrigerate for up to 24 hours. Add 5-10 minutes to the baking time if baking straight from the refrigerator.

Melt butter, whisk in flour to create a roux, gradually add heavy cream and milk while stirring, then mix in Parmesan and Romano cheese. Season with salt, pepper, and nutmeg. Simmer until thickened, about 5-7 minutes.

A crisp green salad with vinaigrette, garlic bread, or roasted asparagus complement this rich bake well. A light white wine pairs nicely for serving to guests.

If the cheese browns too quickly, tent the dish loosely with foil for the first 15 minutes, then remove it to finish baking and achieve that golden top.
