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!

Maggie says
EZ recipe; printed,displayed simply (1 page)… and this sounds perfect to go on homemade noodles (also EZ to make). Thank you.
Kristin says
Hope you enjoy it!!
Beverly Savage says
Tried this tonight. It was very good! I will make it again definitely. I didn’t have any problems with soupiness. In fact, I will probably offer a marinara sauce and put chicken on the side. Thanks for sharing the recipe!
Kristin says
Yea! So glad you enjoyed this!!
Juanita says
Can’t wait to try tonight!!
Kristin says
So, how was it?? Hope you loved it!!
Aimee Hagen says
This was awesome! Did a few changes. Used thighs, skinned and boned them and cut up the meat. Precooked the chicken (just a little bit – not browned, not cooked). Used shaved parm and sprinkled some shredded parm on the top. Omitted season salt (bleah) and garlic. I think the most important thing – I used DUKE’S mayo. The soupiness they refer to makes a fine sauce for the pasta (used bowties). SUPERB!!!
Kristin says
Yum!! I love the changes you made to this and am so happy to hear it was a success!!
Char says
This was easy and delicious meal
Kristin says
So glad you enjoyed it!!
Rose says
Oh my goodness this stuff is yummy. About 15 minutes into baking I heard my grandson say “something smells good” from his room. I “hoped” it was as I rarely just cook a recipe without eating it first. It was a 3 generation hit and that’s not easy because “someone” always has to complain. Not this time. Easy and good. Someone suggested a weekly meal, ha ha ha. Thanks!
Kristin says
Yea!!! That is great news!! Good job!!! So glad everyone enjoyed it!

How many pounds of chicken are you using? Some chicken breast are bigger than others
Kristin says
I use about 2 lbs of chicken when I make this recipe! Enjoy!
Kelly says
The thing that concerns me about using raw chicken instead of cooked is all the liquid the raw chicken will create. I am afraid it will be soupy. I am going to make this and use cooked chicken.
Kristin says
Be sure to let me know how it turns out using the cooked chicken!!
Rebekah says
I made this tonight and it was so easy, quick, and delicious. I used a vegan mayo and it was still full of flavor. I personally LOVED the juice; poured it on my spaghetti squash and soaked it up with my roll. Thank you very much for the recipe. This will definitely be one of my “go to” recipes and I do plan on sharing it with my relatives.
Kristin says
Yea!! So glad it was a hit!!!
Rebekah says
Forgive me for reading all the comments before asking this as I’m sure someone else probably has I’m just short on time. What seasoning did you sprinkle on top?
Kristin says
The green flakes? That is just dried parsley, mainly for adding a bit of color to the picture haha!!
Kathy says
How many pounds is 6 chicken breasts for your recipe?
Kristin says
Depends on the size, but I would say about 2 lbs!
Angela says
You can always just copy and paste the recipe, and get what u need too get,I did that and it worked better then printing what I didn’t need.
Mandy says
The taste is delicious, only change would be to thicken the sauce. I will make this again!
Kristin says
So glad you enjoyed this!!
Bonnie says
