Can I make this Chicken Alfredo Bake ahead of time?
Yes! This Chicken Alfredo Bake can be made in advance and refrigerated. Perfect for make ahead weeknight meals. It will be good up to three days in the refrigerator.
To reheat it simply cover the pasta in aluminum foil and bake it at 350 degrees F until the pasta reaches 165 degrees F. It will take about 30-40 minutes to reheat it in the oven.


Variations
This Chicken Alfredo Bake is really versatile and you can swap in various ingredients.
You can add vegetables like spinach, sun dried tomatoes, mushrooms, or fresh diced tomatoes.
For a different flavor, try using some pecorino romano or asiago cheese instead of the Parmesan.
Try using cheese ravioli or tortellini instead of penne for an extra dose of cheesy flavor.


Can I freeze this Alfredo Chicken Bake?
Yes indeed! To freeze this Chicken Alfredo Bake, prepare completely, then wrap tightly (I like to do plastic wrap then tin foil to prevent freezer burn, but you do you) and freeze flat on a shelf.
To bake, you can either place in the refrigerator overnight to thaw (this is going to give you the best results as the pasta won’t become as mushy since it doesn’t have to cook as long to reheat), then remove the plastic wrap and recover with foil to bake.
You can place the pan from the freezer into the oven while it is preheating, and add 20-30 minutes to the bake time (approximately — cook until heated). I always recommend baking with foil or covering of some sort to prevent drying out.
Top Tips
- Don’t overcook pasta. The pasta is going to continue cooking in the oven so it’s important to not overcook it initially.
- Thin sauce if needed. Alfredo Sauce can become too thick if its simmered at too high of heat or for too long. Simply stir in a little milk until it reaches desired consistency.
- Prevent pasta from clumping. If you’re not using the cooked pasta right away, toss it with a little olive oil. This will prevent it from sticking together.
Save time!
You can use rotisserie chicken. If you want to save more time, then grab some rotisseries chicken.

Barbara Stewart says
I tried this recipe and it was great. I used spinach, mushrooms and onions. It was so delicious and went so quick I had to make it again the following week. I like that the sauce is easy to make not like my other recipe which takes much more time, not to mention more butter (hate those added calories).
Becky Hardin says
Thanks for sharing, Barbara!
Joy says
Easy to make and loved the rich sauce. I just wanted to have a stronger flavor. Could i have added a teaspoon cajun flavor? Ididnt want to over salt it just for flavor. Was the cheese supposed to be measured in a cup or in ounces on the side of the bag.
