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!

I browned the chicken first and used half mayo/half greek yogurt. Also poured the liquid into a saucepan after baking to reduce it & thicken it up. Delish!
Kristin says
So glad you enjoyed it!!!

When I print something there’s a box to check to eliminate images. This should be one page.

I make it with Miracle Whip and its wonderful that way too. I would think using frozen cubed chicken would be fine, just increase the cooking time and make sure its done.
Kristin says
Definitely! I actually just made this for dinner again tonight and used all the suggestions from this post! Stay tuned for a new and improved version, it was even better (if that’s possible) than this one!!
Stephanie says
Try putting the mix in the fridge for a day or at least a few hours before cooking. This keeps it from becoming so “watery/soupy” when making any type of casserole dish.
Kristin says
Great idea! I will try that next time! Thanks!

Hello! I’m going to make this today and I wanted to know if I need to cook the chicken first. I have frozen diced chicken.

I had cooked this dish tonight and it was absolutely scrumptious. One of my favourite so far. I had applied few changes tho. I didn’t layer the mayo and spices on top, I mixed it with the chicken like a marinade that one will cook the meat in it. I added poultry spice and substituted the garlic powder with fresh minced garlic. I also didn’t have enough freshly grated parmesan so mixed with the powdered one I had and some marble cheese. I saved the grated parmesan for the top and added some Italian seasoned bread crumbs. The chicken came out so juicy and soft. OMG it was so delicious . Thank you for sharing this recipe.
Kristin says
What a great idea! I am so glad you enjoyed it!!
Trish says
Did I see somewhere you can combine pasta in dish to make it one dish? Please advise with directions.
Kristin says
I typically like to cook it separately because it is raw chicken in the beginning, but let me check the comments from others and see if someone else has tried it 🙂
Esme says
I made this today and put some bread crumbs on top. In the oven now and smells amazing!
Kristin says
Yea!! How was it???
barbra says
do you bake the casserole covered or uncovered?
Kristin says
Uncovered, just place the pan directly in the oven….this helps brown it up a bit!! 🙂
Enjoy!
Melissa says
I made this yesterday it was delicious. The next time I would brown the chicken a little. We didn’t like the texture of the chicken. Also it would keep the cheese/mayo mixture from becoming watery and it would of browned the cheese better.
Kristin says
Great idea! Glad you enjoyed this!!

To all that are having trouble with printing all the pages just highlight the recipe, then hit print, when the print box appears change the print from all to select. That way you will only print the recipe. I just did.

I made mine with greek yogurt and poured the soupy mixture carefully from the pan over the drained pasta. Problem solved. 🙂
