Ingredients

- 12 ounces penne pasta
- 2 cups cooked chicken, shredded or chopped
- Rotisserie chicken is especially convenient here
- 1 jar (15 to 16 ounces) Alfredo sauce
- 1 cup whole milk
- This helps the sauce coat the pasta more smoothly
- 1 1/2 cups shredded mozzarella cheese, divided
- 1/2 cup grated Parmesan cheese, divided
- 2 ounces cream cheese, softened
- Optional, but it makes the bake extra creamy
- 2 cloves garlic, minced
- 1/2 teaspoon Italian seasoning
- 1/4 teaspoon black pepper
- 1/4 teaspoon salt
- Use less if your sauce is already salty
- 1 tablespoon butter or olive oil
- 1 tablespoon chopped parsley
- Optional, for a fresh finish
Step by Step

1. Heat the oven
Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish.
2. Cook the pasta
Bring a large pot of salted water to a boil and cook the penne until just shy of al dente. It should still have a little firmness since it will finish cooking in the oven. Drain and set aside.
3. Build the creamy sauce mixture
In a large mixing bowl, stir together the Alfredo sauce, milk, cream cheese, garlic, Italian seasoning, black pepper, and salt. Mix until mostly smooth. A few small bits of cream cheese are fine and will melt as it bakes.
4. Add the pasta and chicken
Add the cooked pasta, chicken, 1 cup of mozzarella, and 1/4 cup of Parmesan to the bowl. Fold gently until everything is evenly coated and creamy.
5. Transfer to the baking dish
Spoon the mixture into the prepared baking dish and spread it into an even layer. Top with the remaining mozzarella and Parmesan.
6. Bake until bubbly
Bake uncovered for 25 to 30 minutes, or until the center is hot and the cheese on top is melted and lightly golden.
7. Rest before serving
Let the bake rest for about 5 minutes before serving. This helps the sauce settle and makes each portion easier to scoop.
8. Finish and serve
Sprinkle with chopped parsley if you like, then serve warm. It’s lovely on its own or with a simple green salad and garlic bread.

This is a rich, satisfying dinner, so a smaller portion with a salad or steamed vegetables can make it feel nicely balanced. The protein from the chicken helps make it more filling, while the pasta and sauce bring the comforting texture people usually want from an Alfredo bake.
Health Benefits
This recipe is first and foremost about comfort, but it also has a few practical strengths. Chicken adds protein, which helps make the meal more satisfying and useful for busy evenings when you need something filling. Using cooked chicken also keeps prep simple and cuts down on kitchen time.
You can make the dish a little lighter or more balanced by adding broccoli, spinach, or peas. Whole wheat pasta can also work well if you want a bit more fiber. Even small changes like serving it with vegetables can turn this cozy bake into a more rounded dinner.
Common Mistakes
Overcooking the pasta
If the pasta is fully soft before baking, it can become too tender in the oven. Cook it just under al dente.
Not loosening the jar sauce
Jarred Alfredo sauce can be quite thick. A splash of milk helps the pasta stay creamy instead of dry.
Using too much salt
Many Alfredo sauces and cheeses already contain a good amount of salt. Taste the mixture before adding more.
Skipping the resting time
Right out of the oven, the bake can feel a little loose. A short rest helps it set and serve more neatly.
Baking too long
Too much time in the oven can dry out the edges and make the top overly firm. Remove it once it is hot and bubbly.
Expert Tips
Use rotisserie chicken for the easiest version
This keeps the recipe fast and gives the dish a tender, savory flavor without extra cooking.
Add vegetables without changing the feel of the dish
A cup of steamed broccoli, peas, or sautéed spinach blends in beautifully with the creamy sauce.
Make it extra creamy
A little cream cheese gives the casserole a softer, richer texture, especially when using a basic jar sauce.
Save a little pasta water
If the mixture looks thick before baking, stir in a spoonful or two of pasta water to loosen it gently.
Broil for a golden finish
For a lightly browned cheesy top, broil for 1 to 2 minutes at the end, watching closely.
Store leftovers well
Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat gently with a splash of milk to bring back the creamy texture.
