Cheesy Chicken Alfredo Bake

Cheesy Chicken Alfredo Bake is an easy, creamy pasta casserole filled with tender chicken, rich Alfredo sauce, and plenty of melted mozzarella. Everything bakes together in one pan until the pasta is tender underneath a bubbly, golden layer of cheese.
What makes this recipe especially convenient is that the pasta goes into the casserole completely uncooked. There’s no separate pot of boiling water and no pasta to drain before assembling dinner.
Why You’ll Love This Recipe This is a true four-ingredient comfort-food dinner. Pasta, cooked chicken, Alfredo sauce, and mozzarella are all you need for the basic casserole.
There’s also very little cleanup. The ingredients can be mixed directly in a disposable foil pan, which makes this especially convenient for busy dinners, gatherings, or taking a meal to someone.

And there’s plenty of creamy sauce and cheese throughout. Mozzarella melts over the casserole during the covered bake, then another layer goes on at the end for that bubbly, lightly golden surface.
Using already-cooked chicken keeps things just as simple. Rotisserie-style chicken is perfect here because all you need to do is shred it and mix it with the Alfredo sauce and pasta.
The covered portion of the baking time is important. Trapping the steam inside the pan gives the dry pasta time to soften in the sauce before the casserole is uncovered for that final cheesy finish.
Ingredients You’ll Need

You only need four ingredients:
- Short pasta
- Cooked chicken
- Alfredo sauce
- Mozzarella cheese
How To Make Cheesy Chicken Alfredo Bake
Step 1: Preheat the oven to 375°F (190°C). Place a disposable 9×13-inch aluminum foil baking pan on a sturdy sheet pan for support.

Step 2: Add the uncooked pasta directly to the foil pan and spread it into an even layer. Penne, rotini, or ziti all work well.
Step 3: Add the shredded cooked chicken and both jars of Alfredo sauce. Stir everything together thoroughly until the chicken is evenly distributed and every piece of dry pasta is well coated with sauce.
Step 4: Use the back of a spoon to spread the pasta mixture into an even layer. Keeping the pasta surrounded by sauce is important because it needs that moisture to cook.
Step 5: Sprinkle 1½ cups mozzarella evenly over the pasta and chicken. Reserve the remaining ½ cup for the final topping.

Step 6: Cover the foil pan tightly with aluminum foil, sealing the edges well so steam stays trapped inside the casserole.
Step 7: Bake covered for 35–40 minutes. Carefully check a piece of pasta from the center of the pan. If it’s still too firm, cover the casserole again and bake for another 5–10 minutes.
Step 8: Once the pasta is tender, carefully remove the foil. Sprinkle the remaining ½ cup mozzarella evenly across the top.
Step 9: Return the casserole to the oven uncovered and bake for another 8–12 minutes, until the mozzarella is completely melted, bubbling, and golden brown in spots.

Step 10: Let the Chicken Alfredo Bake rest for 5–10 minutes before serving. This allows the creamy sauce to settle slightly around the pasta.
Cheesy Chicken Alfredo Bake Variations
Extra-Cheesy Alfredo Bake
Increase the mozzarella slightly when you want an especially thick, gooey cheese layer across the top.

Broccoli Chicken Alfredo Bake
Add small, lightly cooked broccoli florets to the chicken mixture for an easy vegetable addition.
Spinach Chicken Alfredo Bake
Fold chopped fresh spinach into the casserole before baking. It will wilt down considerably in the creamy sauce.

Parmesan Chicken Alfredo Bake
Add grated Parmesan with the mozzarella for a sharper, saltier cheese flavor.
Garlic Chicken Alfredo Bake
Add a little garlic powder or minced garlic to the Alfredo mixture for a stronger savory flavor.

Storing Cheesy Chicken Alfredo Bake
Let leftovers cool, then transfer them to airtight containers and refrigerate within two hours. They’ll keep for about 3–4 days.
FAQ
Do I Cook The Pasta First?

No. Add the pasta completely dry. It cooks directly in the Alfredo sauce during the tightly covered portion of the baking time.
Why Does The Pan Need To Be Covered Tightly?
The foil traps steam and moisture inside the casserole, which helps cook the dry pasta. A loose cover can allow too much moisture to escape.
What Kind Of Pasta Works Best?

Penne, rotini, and ziti are all good choices. Short pasta shapes are easier to distribute evenly and coat thoroughly with sauce.
What Chicken Should I Use?
Any simply seasoned cooked chicken works. Rotisserie-style chicken is particularly convenient, but leftover roasted or baked chicken is equally good.
What If My Pasta Is Still Firm?

Re-cover the casserole and bake it for another 5–10 minutes. Different pasta shapes and brands can require slightly different cooking times.
Why Does The Casserole Need To Rest?
The Alfredo sauce is quite loose and bubbling when the casserole first comes from the oven. A short rest helps the sauce settle and cling more closely to the pasta.
The pasta will continue absorbing some of the Alfredo sauce while refrigerated. When reheating, adding a small spoonful of milk or extra Alfredo sauce can help bring back the creamy consistency.

What To Serve With Cheesy Chicken Alfredo Bake
- Garlic bread: Crisp, buttery bread is perfect for scooping up the creamy Alfredo sauce left on the plate.
- Roasted broccoli: Crisp-edged broccoli provides a fresh contrast to the rich chicken, pasta, and mozzarella.
- Green beans: Their simple flavor balances the creamy casserole without competing with the Alfredo sauce.
- Fresh salad: A crisp green salad with tangy vinaigrette helps cut through the richness of the cheese and sauce.
- Roasted asparagus: Tender asparagus makes an easy vegetable side that pairs naturally with creamy chicken pasta.
- Roasted carrots: Their mild sweetness gives you a nice contrast to the savory Alfredo and mozzarella.
Make sure the dry pasta is thoroughly coated and surrounded by Alfredo sauce before covering the pan. Any noodles sitting completely dry above the sauce are much more likely to remain firm.
And don’t remove the foil permanently until you’ve checked pasta from the center of the casserole. Once the pasta is tender, the final uncovered bake is only there to melt and brown that last layer of mozzarella.

This Cheesy Chicken Alfredo Bake is a creamy, comforting dinner loaded with tender chicken, pasta, rich Alfredo sauce, and plenty of melted cheese. It’s easy to make, hearty, and perfect for a cozy family meal or a simple weeknight dinner.
