This garlic parmesan chicken pasta bake turns leftover chicken, rotini, and a creamy cheese sauce into a filling family dinner in about 45 minutes.
The sauce comes together in a single bowl, the oven does the rest, and the top finishes bubbly and golden. It is an easy way to feed a hungry table on a busy weeknight, and the leftovers taste just as good the next day.

Why This Garlic Parmesan Chicken Pasta Bake Recipe Works
Cream, garlic, and two cheeses coat every piece of rotini, so each bite tastes rich without a long list of steps. A splash of reserved pasta water loosens the sauce and keeps it silky after baking, which stops the dish from turning dry or clumpy.
Cooked chicken makes this a true shortcut. Shred leftovers from a roast, a rotisserie bird, or poached breasts, and dinner becomes mostly assembly. Because the chicken is already cooked, the oven time is only about melting the cheese and thickening the sauce.
The dish also scales well and reheats beautifully, which makes it a smart pick for meal prep, potlucks, and nights when everyone eats at a different time. You can double it in two dishes and freeze one for later.
Ingredients for Garlic Parmesan Chicken Pasta Bake
- 1 pound rotini pasta, cooked until just tender
- 2 cups cooked chicken, shredded
- 1 cup heavy cream
- 3 cloves garlic, minced
- 1 cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup reserved pasta water
- Salt for the pasta water, black pepper, and chopped fresh parsley
Rotini pasta. The spiral shape holds sauce in every groove. Cook it until just tender, because it softens a little more in the oven.
Cooked chicken. Shredded breast or thigh meat both work. Use about two cups, lightly packed, and pat it dry so it does not water down the sauce.
Heavy cream. It gives the sauce body and stands up to oven heat without curdling. Milk is too thin for this dish.
Garlic and Parmesan. Fresh garlic and freshly grated Parmesan give the sauce its savory edge. Cheese from a canister melts less smoothly.
Mozzarella. A full cup on top melts into a stretchy, golden layer. Add a handful of breadcrumbs if you want extra crunch.

4. Combine everything Add the drained pasta, chicken, and reserved pasta water to the sauce, then toss until every piece is coated.
5. Bake until golden Spread the mixture into the baking dish and cover it with the mozzarella. Bake for 25 to 30 minutes until the edges bubble and the top turns golden. The center should reach 165 degrees F on an instant read thermometer.

How to Serve Garlic Parmesan Chicken Pasta Bake
Serve each scoop with a crisp Italian house salad and warm fluffy dinner rolls to mop up the sauce. For a vegetable side, try roasted Brussels sprouts or air fryer broccoli. Spoon the pasta into shallow bowls while it is still steaming, and finish with fresh parsley and a little more black pepper.
How to Store and Reheat Garlic Parmesan Chicken Pasta Bake
Cool leftovers within two hours, then keep them in an airtight container in the refrigerator for 3 to 4 days. Freeze portions for up to 2 months and thaw overnight in the refrigerator. Reheat covered with foil at 350 degrees F until steaming hot, or warm single portions in the microwave in 1 minute intervals, stirring between rounds, until the center reaches 165 degrees F. A splash of milk or broth loosens the sauce.
Tips and Variations for Garlic Parmesan Chicken Pasta Bake
Use leftover chicken. Chicken from a roast or a rotisserie bird saves time and adds more flavor than plain poached breast.
Do not overcook the pasta. Pull it a minute early, since it keeps cooking in the sauce and in the oven.
Grate the cheese fresh. Freshly grated Parmesan melts into the sauce, while packaged shreds can stay grainy.
Add crunch. Toss two tablespoons of panko with a teaspoon of melted butter and sprinkle it over the mozzarella before baking.
Add vegetables. Fold in a cup of thawed frozen peas or chopped spinach for color and a little freshness.
Flag the allergens. This dish contains dairy and wheat, so label it clearly when serving guests.
Mind the heat. Set the baking dish on a sheet pan to catch drips, and use oven mitts when you pull it out.
Check trusted guidance. For general advice on storing and reheating leftovers safely, see the Purdue Extension guide to storing leftovers.
