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!

My family LOVED the recipe! As for everyone talking about all the liquid, I actually increased the mayo to get more! It’s the best part! I don’t put olive oil on the spag. I told them use the liquid from the pan. It is SO good and would be a shame to waste! I have many friends who make this now. Everyone loves it! I am about to host a Christmas luncheon soon and this is the meal I’m going to make. For 13 people! Salad, Italian bread and this….perfect easy meal!
Kristin says
Yea!! I am so glad you enjoyed this!!! I hope the luncheon goes well and this is a hit!!
Georgia Reilly says
I’m thinking on how to fix the soupy-ness of this dish. Could we put it on a sheet pan with a grate so that the chicken is above the pan and not sitting in the liquid??
Kristin says
Yep!! I tried that when another commenter said it and it worked great!! Great idea!! Enjoy!
Angi says
Do you cook the chicken before you add it to the dish, or does it cook in the dish?
Kristin says
The chicken cooks in the dish! Hope you enjoy this!!

I’m making this for the 3rd time tonite–I love it! Fresh chopped parsley on top is good to. For those who don’t know how to print, you can either copy and paste it into a Word document to print, or, like I do, I keep all my recipes in a bookmark folder on my laptop, and just bring that bad boy into the kitchen with me when I cook.
Kristin says
Yea! So glad you love this recipe!!

Just stuck it in the oven. Did 1/2 bread crumbs 1/2 parmigian; 1/2 low fat mayo, 1/2 low fat Greek yoghurt and added some sesame seeds for extra crunch.
Cooking it in a baking rack in a 13×9 pan.
The “marinade” tasted amazing before I slathered it on the chicken.
Kristin says
Yea! Hope you enjoyed this! Enjoy!!!
Terrie says
Oops! Just saw that I did not put in seasoned salt, but regular table salt. It’s my error for not reading the recipe carefully! Still was delicious!
Kristin says
Hehe, I did that before too!! Its yummy either way, glad you enjoyed it!
Terrie says
We made this tonight (using mayonnaise) and it was delicious! Thank you for sharing this recipe. Yes, there was juice in the bottom…as you warned us there would be…..but a slotted spoon easily took care of it. Worth the deliciousness,
Kristin says
So glad you enjoyed this!!

If you cut the chicken up in cubes, how do you get the mayo & spices on the chicken pieces to stay on top. I haven’t made this yet but plan to hopefully tomorrow. Everyone including yourself have mentioned the chicken comes out soupy. How would that allow the pieces to get browned like yours? And the soupy juices, can’t they be used as a broth or gravy to go over the pasta and chicken? or cook pasta in same pan with chicken after its browned. Someone mentioned cooking the pasta with the chicken. I do this all the time when making spaghetti. I brown the meat with onion and garlic, once the meat is a dark golden, I put my tomatoes, tomato paste, and seasonings to meat mixture and cooked for about 20-30mins., then I add chicken broth (instead of water) and the spaghetti, mix well and cover and cook for about 15mins. Its’ so easy making it all in one pan, and the pasta is a perfect al dente not over cooked at all.
This can be done with Chicken Alfredo, anything like that.
Kristin says
You mix the mayo and spices together and just spread it on top best you can. The top of the chicken will get browned, the juices will be on the bottom. I believe the pasta cooking in the juices would work great, several have tried it that way and said it did, I just haven’t tried that! I hope you enjoy this! Keep me posted!

There is a printer friendly button and after you select it the next page opens and you can then choose to remove the image .. I printed one page for this recipe .. Cannot wait to try it thank you so much for sharing !!!
Kristin says
Hope you enjoy!!
Elaine says
How do you think it would be if you put the noodles in first and cooked it with the rest of the recipe?
Kristin says
I know a few people have tried that and said it works perfectly. I haven’t tried it as my only concern is cooking the pasta in liquids mixed with raw chicken. Once cooked though, it shouldn’t be an issue. It definitely works great though!
Phyllis McKinley says
Wonder if you could add broccoli florets to this? I am making tonight.
Kristin says
That would be a great addition! Hope you enjoy this!
Lisa says
