Baked Chicken Alfredo Penne Pasta Recipe: One-Pan Creamy Comfort with Crispy Top

This baked chicken alfredo penne pasta recipe transforms weeknight dinner into restaurant-worthy comfort food with minimal effort. The secret lies in baking everything together—juicy chicken, alfredo sauce, and penne—until the top forms a golden, crispy crust while the pasta stays perfectly tender underneath.

I developed this one-pan method after burning through three separate batches of chicken and sauce, and it finally delivers the creamy, satisfying meal I craved without the mess.

The magic happens in the sauce, where heavy cream and parmesan blend into a velvety alfredo that clings to every strand of penne, while the chicken cooks through in the same dish.

No need for fancy techniques—just a single baking sheet, 45 minutes of oven time, and a sprinkle of breadcrumbs for that coveted crispy finish. This recipe proves you don’t need a stovetop to create restaurant-quality pasta; the oven does all the work while you prep sides or set the table.

What you’ll end up with is a dish that’s equal parts indulgent and impressive: tender chicken pieces nestled in a pool of creamy alfredo sauce, with perfectly cooked penne peeking through. The crispy breadcrumb topping adds a satisfying crunch that contrasts beautifully with the rich, velvety sauce underneath.

It’s the kind of meal that feels like a hug for your taste buds—comforting, creamy, and impossible to resist.

Perfect for feeding a family or hosting dinner guests, this recipe scales easily and reheats beautifully. The one-pan method means fewer dishes to clean, and the flavors only deepen as it sits, making it ideal for meal prep or last-minute gatherings. Let’s get started on this creamy, crispy, one-dish wonder.

Ingredients for baked chicken alfredo penne pasta

Pantry staples plus a few fresh touches—this one-pan dinner delivers restaurant-style comfort with zero fuss.

The chicken should be tender but not dry, so boneless, skinless breasts are ideal—cut them into even pieces so they cook at the same rate. Trader Joe's or Whole Foods sell pre-cut chicken that saves time, but any grocery store works. For the pasta, Barilla or De Cecco are my go-tos—they hold up better during baking. The heavy cream is non-negotiable here; full-fat makes all the difference in that velvety alfredo texture. If you're watching calories, you can sub half with whole milk, but trust me on the full-fat version.

No panko? Toasted breadcrumbs from a baguette work just as well—just pulse them in a food processor for a finer texture. Fresh shallots add depth, but yellow onion works in a pinch. The nutmeg is subtle but essential—if you don't have it, skip it or use a pinch of cinnamon. For the cheese, grate it yourself—pre-shredded gets clumpy and won't melt smoothly. The garlic powder and minced garlic are a dynamic duo; don't skip either. Pro tip: Toast the breadcrumbs in olive oil before adding them to the top for extra crispiness.

This dish reheats beautifully—honestly tastes better the next day once everything melds. Store leftovers covered in the fridge for 3-4 days, or freeze portions for up to 3 months. I always make a double batch because it disappears fast. The crispy topping gets soggy if you reheat it covered, so pop it under the broiler for 2-3 minutes to restore that golden crunch.

Step-by-step instructions for baked chicken alfredo penne pasta

Here's how to make this creamy, crisp-topped one-pan wonder that's easier than takeout.

Cut the 1.5 lb boneless chicken breast into 1-inch bite-sized pieces—this ensures everything cooks through evenly. In a large bowl, toss the chicken with 2 tbsp olive oil, 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder. Let it sit while you prep the rest.

Rinse the 12 oz penne pasta under cold water to remove excess starch, which helps prevent gummy sauce later. I like to break it into thirds—this makes it easier to layer later and prevents a solid pasta wall in the middle of your pan.

Preheat your oven to 375°F. In a 9x13-inch baking dish, melt the 0.5 cup unsalted butter over medium heat on the stovetop. Add the 2 minced shallots and cook for 3-4 minutes until soft and translucent. Stir in the 4 minced garlic cloves and cook for 30 seconds until fragrant—don't let it brown or it'll turn bitter.

Pour in the 1 cup heavy cream and bring to a gentle simmer. Sprinkle in 1 cup freshly grated Parmesan cheese, 0.25 tsp nutmeg, and 0.5 tsp black pepper. Stir constantly for 2-3 minutes until the cheese melts completely and the sauce thickens slightly. This is your flavor foundation—taste it now and adjust salt if needed.

Spread half of the penne pasta in the baking dish, creating an even layer. Top with half of the seasoned chicken pieces, then pour about ⅓ of the Alfredo sauce over it. Repeat with another layer of pasta and chicken, then finish with the remaining pasta and sauce. The goal is even distribution so everything cooks at the same rate.

Here's the secret to that crispy top: In a small bowl, mix the 0.5 cup panko breadcrumbs with 1 tbsp dried parsley and 0.5 tsp salt. Sprinkle this evenly over the entire dish. Press down gently with a spatula—this prevents the breadcrumbs from floating away when you bake it.

Transfer the baking dish to the preheated oven and bake for 20 minutes. After 15 minutes, the sauce should be bubbling and the top should start turning golden. If it's browning too quickly, tent loosely with foil to prevent burning while still allowing the top to crisp.

For the final 5 minutes, crank the oven to 400°F to get that perfect golden crust on top. You'll know it's done when the top is deep golden brown and the internal temperature of the chicken reaches 165°F (use an instant-read thermometer). Let it rest for 5 minutes before serving—this gives the sauce time to thicken slightly and the chicken to reabsorb juices.

Use a spatula to scrape up any crispy bits from the bottom of the pan and redistribute them on top. Garnish with extra dried parsley and an additional sprinkle of Parmesan cheese if you're feeling fancy. The contrast between the creamy sauce, tender chicken, al dente pasta, and crispy top is what makes this dish so special.

Serve immediately with a simple side salad or garlic bread to soak up every last bit of that rich Alfredo sauce. This one-pan meal delivers all the comfort of your favorite Italian restaurant—without the mess or the wait!
