This Parmesan Chicken Casserole comes together in no time using only 6 ingredients! Flavorful, family approved, and a blog favorite!
Since my “Melt in your Mouth Chicken” has been such a hit with everyone, I decided to change it up just a bit and make it more into a casserole. Not too many changes to the original dish, mainly just the fact that instead of using whole chicken breasts, it is diced chicken, making it easier to serve over something! I served this over spaghetti noodles last week and the entire family was ranting and raving over how yummy this was.
The cooking time was less due to the chicken being cut up, the flavor was amazing, and the chicken was incredibly moist. The leftovers the next day were just as good, making this a meal I will definitely make again!!

If you want to make this a bit more healthy, you can use plain Greek yogurt in place of the mayonnaise. It works, but it doesn’t have as rich and creamy of a flavor! And yes, after several people telling me this isn’t really a “casserole”, I agree, however, since its cooked in a casserole pan….I ran with it, haha!
Serve over rice, pasta, in a lettuce wrap, or as is! Even perhaps cauliflower rice, zoodles, etc. for healthy options!

The one who complained about the printing issue, I believe is not very good at her/his own printer settings, or to cliick on the print friendly button. i have printed many of yours and never had a problem. Thank you very much for sharing it with us!

Has anyone tried using rotisserie or canned chicken?
Kristin says
Canned chicken I would think is too moist and “crumbly” if that makes sense. Rotisserie may work, but may end up drying out the chicken when baked. Certainly worth a shot though!!
Teresa says
Man oh man, seeing these “adults” complain about printing problems makes me cringe…when I print something I always do a print preview first to see what I am printing looks like and then adjust accordingly. Instead of complaining, why not try to do something productive and solve the “problem” yourself? On topic: this recipe was yummy. My 4 year old daughter loved it. The only thing I would suggest is trying to get some more of a sauce to it. I just added butter and more parmesan to the noodles to make it a bit more savory.
Kristin says
So glad you enjoyed it!! <3

I freeze things with mayo all the time. Sometimes pre cooked and sometimes not. I never knew there was a problem with freezing mayo. It is a processed food, what sort of problem would there be? I can’t wait to make this recipe.
Kristin says
Hope you enjoy it as much as my family does!!
Beth says
Wow all these people complaining about the printer friendly issue. Geez what miserable people, write down the recipe then and get off the gas.

Ann says
Sounds delicious. When I make it, I will used chopped, cooked chicken. Bake at 350 for 30 min or until heated through. Eliminates the soupiness from the raw chicken juices. Have a recipe for poppyseed chicken that does this.
Kristin says
Great idea! Be sure to let me know how it turns out so I can add it to the recipe 🙂

With the extra liquid from cooking , has anyone ever tried cooking with pasta of choice in recipe at the same time
Kristin says
I have heard some mention that, however, I have never tried it. I don’t see why it wouldn’t work though!
Misty Critchfield says
This recipe is “to die for”! Thank you so much! perfect saltiness, moist, tender chicken and pleasant browned appearance! Even my picky nephews ate it! Also, a bonus for me is the yogurt. I am allergic to mayo, so, sooooo happy to have this recipe.
Thank you so much!
P.S. It pairs perfectly with spaghetti noodles with red sauce……..I put it on top…..even more deliciousness! 🙂
Again thank you…..love you guys!
Kristin says
