Some nights call for a single dish, a hot oven, and very little washing up afterwards. This bake is that dinner. You get tender penne folded through a real parmesan cream sauce, plenty of chicken in every scoop, and mozzarella on top that turns bubbly and deep gold at the edges.
It eats like stovetop Alfredo. Rich. Garlicky, in a good way. But the oven does the last stretch of work for you, so you are not stuck stirring while everything else goes cold. In our kitchen we assemble it earlier in the day when there is a spare ten minutes, cover it, and leave it in the fridge. Then it is just bake and serve. No drama. No sink full of pans.
A Casserole That Tastes Like the Stovetop Version
Pasta bakes fail in one predictable way. The noodles keep drinking.
They go into the oven already cooked, they soak up sauce for another twenty odd minutes, and what comes out is soft, swollen, and a bit sad. Here the penne is boiled 2 minutes shy of the package directions. Still firm in the middle. Almost stubbornly so. It finishes in the sauce instead, which is exactly where you want it to finish.
The sauce has a quiet helper, too. Cream cheese, whisked into the warm cream a few cubes at a time. It brings a faint tang and helps the sauce stay smooth through baking instead of splitting. Parmesan goes in off the fiercest heat. That matters. Cheese that hits liquid at a hard boil can turn grainy, while cheese melted gently stays silky.
Half the mozzarella gets folded through the pasta, so the cheese is not just a lid. The rest goes on top to brown. Then comes the rest out of the oven. Five minutes, long enough for the sauce to settle and cling, so a spoon lifts a creamy scoop instead of leaving a puddle behind.

Gather These First
Rotisserie chicken is the shortcut we reach for most often, mostly because it is already cooked and the meat shreds easily. Any cooked chicken you have on hand works just as well.
- 12 ounces penne pasta
- 2 tablespoons unsalted butter
- 3 cloves garlic, minced
- 2 cups heavy cream
- 4 ounces cream cheese, softened and cut into cubes
- 1 cup freshly grated parmesan cheese, divided
- 1/2 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon ground nutmeg (optional)
- 3 cups cooked chicken, shredded or cubed (about 1 1/4 pounds)
- 2 cups shredded low-moisture mozzarella, divided
- 2 tablespoons chopped fresh parsley
Penne is the first choice here: the tubes catch sauce inside and out. Ziti works. Rigatoni works. Rotini, with all those twists, works beautifully too.
Grate the parmesan yourself if you can. Pre-shredded cheese is coated so it does not clump in the bag, and that coating can make a sauce feel sandy. Freshly grated melts clean.
Low-moisture mozzarella is the one for the top. It browns. It stretches. Fresh mozzarella lets out too much water for a bake and can leave the top soupy. For a lighter pan, swap half the cream for whole milk and add a teaspoon of cornstarch to the sauce. Gluten-free penne also works; boil it 3 minutes shy, since it softens faster in the oven.
Assembling the Bake
- Heat the oven to 375 degrees F and lightly grease a 9 by 13 inch baking dish. Bring a large pot of well salted water to a boil.
- Boil the penne 2 minutes less than the package directs for al dente. It should still have a firm bite in the center. Scoop out 1 cup of the hot pasta water, then drain the pasta and set it aside.
- In the same pot or a large deep skillet, melt the butter over medium heat. Add the garlic and cook 30 seconds, just until it smells fragrant. Do not let it brown.
- Pour in the heavy cream and bring it to the barest simmer. Add the cream cheese a few cubes at a time, whisking until each batch melts before adding more. Simmer gently for 2 to 3 minutes, until the sauce thickens enough to coat a spoon.
- Take the pot off the heat and whisk in 3/4 cup of the parmesan, the salt, pepper, and nutmeg if using. Stir until the cheese is fully melted and the sauce is smooth. If it looks thicker than heavy cream, whisk in a splash of the reserved pasta water.
- Add the drained pasta, the chicken, and half of the mozzarella to the sauce. Fold everything together until the pasta is evenly coated, then pour it into the prepared baking dish and spread it into an even layer.
- Sprinkle the remaining mozzarella and the remaining 1/4 cup of parmesan evenly over the top.
- Bake, uncovered, for 20 to 25 minutes, until the sauce is bubbling around the edges and the top is melted. For a deeper golden top, broil for 1 to 2 minutes at the end and watch it closely, because cheese goes from golden to burnt in a blink.
- Rest the bake for 5 minutes so the sauce settles. Scatter the parsley over the top and serve hot, straight from the dish.
Getting the Sauce Right
- Undercook the pasta on purpose. Those 2 minutes are not a suggestion. Pasta that tastes perfect straight from the pot will be mushy after 25 minutes in a hot, saucy oven, and there is no pulling it back.
- Soften the cream cheese first. Cold cubes dropped into hot cream melt into stubborn little lumps that refuse to whisk out. Thirty minutes on the counter fixes it. In a hurry? Twenty seconds in the microwave does the same job.
- Warm sauce, warm pasta. Put them together while both are hot. The sauce coats evenly that way instead of clumping in cold patches, and the whole dish heats through at the same pace in the oven.
- Do not overbake. Bubbling edges and a melted top mean you are done. Extra time just dries the sauce at the corners and makes the chicken firm and a little tired.
- Rest before serving. Five quiet minutes let the sauce thicken into a proper coating. Skip it and the first scoop looks soupy, even though the flavor is right there. Wait. It is worth it.
Variations Worth Trying
Broccoli is the version asked for most often. Stir 3 cups of small broccoli florets into the pasta water for the last 2 minutes, drain together, and fold through the sauce. It stays green and keeps a little bite.
Bacon and peas are another easy turn: 6 slices of cooked, crumbled bacon and a cup of frozen peas. Salty, sweet, very forgiving. For a Cajun angle, season the chicken with 2 teaspoons of Cajun seasoning and add a diced bell pepper with the garlic. Spinach and sun-dried tomatoes push it toward restaurant territory without changing the method.
Want it lighter on dairy? Use whole milk plus a cornstarch slurry in place of half the cream. A touch less rich. Still good.
For company, try shrimp: swap the chicken for 1 pound of peeled raw shrimp, fold through at the same point, and bake just until pink and curled, right around the same timing. A handful of baby spinach stirred into the hot pasta wilts in seconds and adds color.
Make-Ahead and Storage
Cover leftovers tightly and refrigerate for up to 3 days. To reheat a portion, stir in a spoonful of milk and warm it in the microwave. That little bit of milk wakes the sauce up. For the whole dish, cover with foil and warm at 350 degrees F for about 20 minutes.
This bake freezes well before baking. Build it in a foil pan, wrap tightly, and freeze up to 2 months. Thaw overnight in the refrigerator and bake as directed, adding about 10 minutes. Baked leftovers freeze too, though the pasta softens a little more on the second round.
If a reheated sauce looks tight or clumpy, another spoonful of milk and a gentle stir over low heat brings back the glossy, creamy look.
Questions, Answered
Can I assemble this ahead of time?
Yes. It is one of the best things about it. Assemble the whole dish, cover it, and refrigerate up to 24 hours. Let it sit on the counter for 20 minutes while the oven heats, then bake as directed, adding 5 to 10 minutes since it starts cold.
What is the best pasta shape for Alfredo bake?
Short, sturdy shapes with ridges or tubes win here: penne, ziti, rigatoni, and rotini all hold sauce and keep their bite. Long noodles like fettuccine tangle in a dish and dry out at the edges. Whatever shape you choose, the 2 minutes shy rule still applies.
Can I use jarred Alfredo sauce?
In a genuine pinch, two 15 ounce jars can stand in for the homemade sauce and the bake will still be decent. Warm the jarred sauce, stir in the cream cheese and half the parmesan, and it will taste much closer to homemade. When you have the extra 8 minutes, though, the from-scratch sauce is worth it. The garlic is fresher. The parmesan actually tastes like parmesan.
Why did my sauce turn grainy?
Graininess usually comes from cheese hitting liquid that is too hot, or from pre-shredded cheese with anti-caking coatings. Take the pot off the heat before adding parmesan, add it gradually, and keep the sauce at a gentle simmer rather than a boil. A splash of pasta water and a good whisk can rescue a mildly grainy sauce, so try that before you judge the whole pan.
