| Chicken Broth 💧 | ½ cup | Low-sodium preferred |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |

The chicken thighs are the star here—boneless, skinless, and bite-sized for even cooking. Most grocery stores carry pre-cut thighs, but if you're buying whole, trim and portion them yourself. I always grab organic thighs from Whole Foods when possible, but regular supermarket brands work fine too. Look for plump, firm pieces with good marbling—this ensures juiciness after baking. The penne pasta should be high-quality, uncooked—look for brands like Barilla or De Cecco in the pasta aisle, or grab the organic dry pasta at Trader Joe's for a slightly nuttier flavor.
No heavy cream? Full-fat coconut milk works in a pinch, though the texture will be slightly lighter. Substituting Parmesan? Pecorino Romano has a sharper bite, but use one-third less since it's saltier. Fresh parsley wilting? Dried parsley works at half the amount, though it won't be as vibrant. For the garlic, jarred minced garlic is fine (just drain it well), but freshly minced adds that restaurant-quality depth. The chicken broth can be swapped for white wine if you prefer—just reduce it by half first to avoid a watery sauce. And if you're avoiding gluten, gluten-free penne holds up perfectly in this recipe.
This dish reheats beautifully—cover with foil and bake at 375°F for 15 minutes to restore creaminess. Store leftovers in an airtight container for up to 4 days, though I find it tastes best within 2 days. For make-ahead prep, par-cook the pasta (al dente) and store separately, then assemble and bake fresh. The sauce thickens as it cools, so add a splash of milk or broth when reheating if needed. Garnish with extra Parmesan and parsley right before serving—that fresh pop of color makes all the difference.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this—just toss everything on a sheet pan, bake, and walk away. No boiling pasta separately, no saucepans to scrub. The chicken thighs stay juicy while the penne soaks up that creamy alfredo right next to them.
- Garlic-Parmesan Euphoria: That moment when you pull it out of the oven? The garlic’s got a little char, the parmesan’s melted into a glossy blanket, and the heavy cream makes it ridiculously rich. It’s the kind of dish that makes you close your eyes and sigh.
- Weeknight to Dinner Party: Honestly, I’ve served this to my book club and my exhausted self on a Tuesday. The same recipe works—just add a sprinkle of fresh parsley for fanciness if you’re feeling it. (Between us, no one ever notices the difference.)
- Budget-Friendly Leftovers: Chicken thighs are cheaper than breasts, and this makes enough for three meals. The next day, I toss it into a salad or reheat it with a side of garlic bread—still tastes like a restaurant dish, but for half the cost.
Step-by-step instructions for baked chicken alfredo penne pasta
Here's how to create a rich, one-pan Alfredo masterpiece with perfectly balanced flavors.
Sear the Chicken for Maximum Flavor
Preheat your oven to 400°F. Heat the 1 tablespoon olive oil in a large oven-safe skillet over medium-high heat. Add the 1.5 lb boneless, skinless chicken thighs, cut into bite-sized pieces, and cook for 5-6 minutes until the edges are golden brown and the chicken is cooked through.
Here's the thing—searing the chicken first builds deep flavor that carries through the creamy sauce. I like to press down gently on the chicken pieces during the first minute to prevent curling. Once the chicken is cooked through, remove it from the skillet and set it aside on a plate.
Build the Creamy Alfredo Sauce
In the same skillet (no need to clean it—those browned bits are pure flavor), reduce heat to medium and add 2 tablespoons all-purpose flour. Stir constantly for 1-2 minutes until the flour turns a light golden color and you smell a toasty aroma. This creates our roux base.
Slowly pour in the 1 cup heavy cream while whisking vigorously to prevent lumps. Add the 4 cloves minced garlic, 0.5 cup chicken broth, 1.5 teaspoons salt, and 0.5 teaspoon ground black pepper. Stir well and bring to a gentle simmer for 3-4 minutes until the sauce begins to thicken slightly.
Cook the Pasta in the Sauce
Add the 12 oz penne pasta to the skillet, stirring to coat the noodles thoroughly with the sauce. Pour in just enough water to cover the pasta by about 1 inch—you want enough liquid to cook the pasta but not so much that it dilutes the sauce. Return the skillet to medium-high heat.
Bring to a boil, then reduce heat to medium-low and cover with a tight-fitting lid. Cook for 12-14 minutes, stirring occasionally, until the pasta is al dente (you should have a slight bite when you taste it). The pasta will absorb the sauce as it cooks, creating that perfect creamy texture we're after.
Finish with Cheese and Bake
Remove the skillet from heat and stir in the 1.5 cups freshly grated Parmesan cheese and the 0.25 teaspoon red pepper flakes (if using). Return the chicken pieces to the skillet and toss everything together gently to combine. The residual heat will melt the cheese into a luscious sauce.
Transfer the skillet to the preheated oven and bake for 8-10 minutes until the sauce is bubbly and the edges are lightly golden brown. This final baking step ensures every strand of pasta gets coated in that rich, creamy Alfredo goodness.
Garnish and Serve Immediately
Remove the skillet from the oven and let it rest for 1-2 minutes before serving. Garnish with the 0.25 cup chopped fresh parsley and an extra sprinkle of Parmesan cheese if desired. The sauce should be thick and velvety, clinging beautifully to each strand of pasta.
Serve immediately while hot—this dish doesn't wait. Each bite should deliver tender chicken, perfectly cooked al dente pasta, and a rich, creamy sauce that melts in your mouth. The one-pan method makes cleanup a breeze while delivering restaurant-quality results at home.
Pro Tips For Making Baked Chicken Alfredo Penne Pasta
- Sear Chicken First: I learned this the hard way—skipping the sear means bland, rubbery chicken in your baked dish. Hit a screaming-hot pan with 1 tablespoon oil, then cook the thighs skin-side down for 4-5 minutes until deep golden. The crust locks in flavor and keeps them juicy when baked later.
- Pre-Cook the Pasta: Undercooked pasta ruins everything. Boil penne 1 minute less than package instructions, drain, and toss with a splash of pasta water and a pinch of salt. This prevents a gummy sauce later—your alfredo will cling perfectly instead of turning into a soup.
- Blend Cold Cream: Warm heavy cream straight from the fridge before mixing into the sauce. Cold cream blends smoother and doesn’t curdle when you add garlic or Parmesan. Use an immersion blender for silky texture—no lumps, no stress.
- Grate Fresh Garlic: Minced garlic burns fast and adds bitterness. Instead, finely grate 2 cloves (peel first) and cook them in butter for 30 seconds until fragrant but still pale. This keeps the sauce bright and flavorful without overpowering the cream.
Best sauces and condiments for this dish
Classic Alfredo Upgrade
Take your sauce to the next level by adding 1 tablespoon lemon juice when you incorporate the Parmesan. This brightens the richness without overpowering it. I also love stirring in 1 teaspoon Dijon mustard during the roux stage—it adds subtle tang that balances the creaminess perfectly.
These small tweaks transform a basic Alfredo into something truly special. 💫
Creamy Variations
For a lighter version, swap half the heavy cream for whole milk>—the sauce stays rich but with slightly less decadence. If you're avoiding dairy entirely, use unsweetened cashew cream> (blend 1 cup soaked cashews with ½ cup water) for a velvety texture.
Both alternatives work beautifully while keeping the dish creamy and satisfying.
Spicy Kick Options
Add ½ teaspoon smoked paprika when building the roux for a subtle smoky depth. For serious heat, stir in 1 teaspoon hot honey> after baking—it caramelizes slightly on the hot pasta, creating a perfect sweet-spicy contrast. I find this works especially well with the chicken's natural juiciness. 🌶️
Herb Infusions
Fresh herbs elevate this dish instantly. Along with parsley, try ½ teaspoon dried thyme> during the roux stage or 1 tablespoon chopped basil> at the end.
For a more sophisticated touch, add ½ teaspoon grated nutmeg> when melting the Parmesan—it adds warmth that pairs perfectly with the creamy sauce.
Umami Boosters
For deeper flavor, stir in 1 teaspoon fish sauce> when adding the chicken broth or sprinkle ½ teaspoon nutritional yeast> over the finished dish. Both add umami richness without altering the dish's fundamental character.
I particularly love the fish sauce—it's a secret weapon in many Asian-inspired sauces that works surprisingly well here. 🍜
Sauce Consistency Tips
If your sauce turns out too thick, thin it with 1-2 tablespoons warm chicken broth> while baking. For extra richness, stir in 1 tablespoon cold butter> at the end—it creates a luxurious sheen.
The key is balancing the sauce consistency so it coats the pasta beautifully without being watery. I always taste as I go to adjust seasoning and thickness. ✨

Frequently asked questions
Can I use chicken breasts instead of thighs?
Chicken breasts work, but thighs are ideal for this recipe because they stay juicier during baking. If using breasts, cut them into ½-inch thick pieces and bake for 2-3 minutes less to avoid drying out. Pound them lightly with a meat mallet for even cooking. For extra moisture, marinate them in 1 tablespoon olive oil and 1 teaspoon lemon juice for 15 minutes before cooking.
How do I prevent the sauce from getting too thin?
Start with a proper roux—cook the 2 tablespoons flour in the skillet until it turns golden and smells nutty (1-2 minutes). Use full-fat heavy cream instead of lighter options, and stir in the 1.5 cups Parmesan off the heat to melt it smoothly. If the sauce still seems too thin after baking, remove the dish from the oven and simmer uncovered for 2-3 minutes to thicken it.
Can I make this recipe ahead of time?
Yes! Assemble the dish (without baking) up to 24 hours ahead and refrigerate in an airtight container. When ready to bake, cover the skillet with foil and bake at 375°F for 15-20 minutes, adding 1-2 tablespoons warm chicken broth if needed to restore creaminess. For a make-ahead shortcut, par-cook the pasta al dente (undercook by 1 minute), drain, and toss with a little olive oil to prevent sticking.
What if I don’t have penne pasta?
Any short pasta shape works—try rigatoni, farfalle, or fusilli. Long pasta like spaghetti or linguine won’t work as well because it won’t absorb the sauce evenly. If using a different shape, adjust cooking times slightly—smaller shapes like orzo cook faster (8-10 minutes), while larger shapes like rigatoni may need 15-16 minutes.
Why did my chicken turn out dry?
Overcooking is the most common cause. Chicken thighs should reach 165°F internally but shouldn’t bake longer than 5-6 minutes in the skillet. Use a meat thermometer to check doneness. For extra juiciness, add 1 tablespoon chicken broth to the skillet after searing, then bake covered for 3-4 minutes to steam the chicken. Also, avoid cutting the chicken too small—1-inch pieces stay moist longer.
