Creamy Baked Chicken Alfredo Pasta
This Creamy Baked Chicken Alfredo Pasta is the kind of dinner that makes a weeknight feel a little more special.
Tender chicken, al dente pasta, and a rich garlic-Parmesan sauce bake together until bubbly and golden.
Why This Baked Alfredo Works
I keep coming back to this one because it hits all the notes, creamy sauce, juicy chicken, and a crispy cheese top, without dirtying every pan in the kitchen.
The sauce gets a boost from a pinch of nutmeg and plenty of black pepper, so it tastes layered, not flat.
And because it bakes in a single dish, you spend less time at the sink and more at the table.
Ingredients
- 1 lb boneless, skinless chicken breasts – cut into bite-size pieces
- 8 oz penne pasta – or any short pasta
- 2 tbsp unsalted butter
- 3 cloves garlic, minced
- 2 tbsp all-purpose flour
- 1 ½ cups whole milk
- ½ cup heavy cream
- 1 cup grated Parmesan cheese – freshly grated melts best
- 1 cup shredded mozzarella cheese – for that pull
- ½ tsp salt, plus more for pasta water
- ¼ tsp black pepper, freshly cracked
- Pinch of ground nutmeg (optional, but it wakes up the cheese)
Variations / Substitutions
- Rotisserie chicken – shred 2 cups and skip the browning step. Dinner comes together even faster.
- Shrimp – swap in 1 lb raw shrimp, cook them just until pink before the sauce, then proceed.
- Vegetable add-in – fold in 1 cup of steamed broccoli florets or baby spinach when you toss everything together.
- No heavy cream – use all whole milk if that’s what you have. The sauce will be a touch lighter but still creamy.
- Dairy-free – use unsweetened oat milk in place of the milk and cream, and a good dairy-free Parmesan alternative. The texture changes a bit, but it works.

How To Make Baked Chicken Alfredo Pasta
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the 8 oz penne and cook until al dente, about 1 minute less than the package time says, because it will soak up more liquid in the oven.
Drain and set aside. The pasta should still have a little bite at the center.
Step 2: Brown the Chicken
While the water heats, season the chicken pieces with the ½ tsp salt and ¼ tsp pepper. Warm a drizzle of oil in a large skillet over medium-high heat. Add the chicken in a single layer and let it sear for about 3 minutes without moving it, then stir and cook another 2 to 3 minutes until golden on the outside and no longer pink inside. Transfer the chicken to a plate.
Step 3: Start the Alfredo Sauce
Lower the heat to medium. Melt the 2 tbsp butter in the same skillet, then add the 3 minced garlic cloves and cook just until fragrant, about 30 seconds. Whisk in the 2 tbsp flour and let it bubble for a minute to cook off the raw flour taste. Slowly pour in the 1 ½ cups whole milk and ½ cup heavy cream, whisking constantly to keep things smooth. Let the sauce simmer, stirring often, for about 2 minutes until it thickens enough to coat the back of a spoon. Remove the pan from the heat, then stir in the 1 cup grated Parmesan and a pinch of nutmeg. Taste and add a little more salt or pepper if it needs it. The sauce will be thick and glossy.
Step 4: Toss and Assemble the Dish
Preheat the oven to 375°F (190°C). Add the drained pasta and the cooked chicken back into the skillet with the sauce. Gently toss until every piece of pasta is coated. Spread the whole mixture into a greased 2 quart baking dish, then scatter the 1 cup shredded mozzarella over the top in an even layer. It will already look tempting.
Step 5: Bake and Serve
Slide the dish into the hot oven. Bake for about 20 minutes, until the edges are bubbling and the top is golden in spots. If you like a darker, crispier top, turn on the broiler for the last minute. Let it sit for just a few minutes after it comes out, then scoop onto plates and serve while it’s still hot and stretchy.
Tips for the Best Baked Alfredo
- Undercook the pasta a little. The pasta will absorb more liquid as it bakes, so stopping a minute early keeps it from turning soft.
- Grate your own cheese. Pre-shredded Parmesan and mozzarella often have anti-caking coatings that can make the sauce gritty instead of smooth.
- Thin the sauce if needed before baking. If the sauce seems too thick after you toss everything together, stir in a splash of milk. It will tighten up in the oven.
- Let it rest, but not for long. Five minutes on the counter is plenty. You want it hot enough to still have that cheese pull.
Storing and Reheating Baked Chicken Alfredo
- Refrigerate – Cool the leftovers completely, then store in a sealed container for up to 4 days.
- Reheating – Warm individual portions in the microwave with a splash of milk to loosen the sauce. For a larger amount, cover the dish with foil and reheat at 350°F (175°C) until warmed through. The sauce may separate a little, but a quick stir brings it back together.
What To Serve With Baked Chicken Alfredo Pasta
A crisp green salad with a sharp lemon vinaigrette cuts through the richness of the cream sauce beautifully. For something green on the plate, roasted asparagus or simple steamed green beans work well without competing. And if you want to go full comfort, a slice of garlic bread never hurts.
Frequently Asked Questions
Can I make this Baked Chicken Alfredo ahead of time?
Yes. Assemble the dish up to a day in advance, cover, and refrigerate. When you’re ready to bake, add about 5 extra minutes to the oven time since it will start cold.
Can I freeze it?
You can, though the cream sauce may separate slightly when thawed. For best results, freeze the assembled unbaked dish, then bake from frozen, adding 15 to 20 minutes, or thaw overnight in the fridge first.
Why did my sauce turn out grainy?
High heat or adding the cheese while the pan is still on the burner usually causes graininess. Pull the pan off the heat before you stir in the Parmesan, and do it gently. Pre-shredded cheese can also cause it, so grate it yourself.
Can I use a different pasta shape?
Absolutely. Rotini, rigatoni, or fusilli all grab the sauce well. Just cook it to the same al dente stage you would for penne.
