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!

Kristin says
Keep me posted if you try it!! 🙂
Laurel says
Did your chicken brown like that (in the picture) or did you brown it a little first.?
Kristin says
It browned like that all by itself 🙂
I believe it was the Parmesan that browned up, be sure to use shredded instead of grated!!
kori says
It was so delicious!! My husband and I loved it!
Kristin says
So glad you both enjoyed this!!

I made this tonite, and it was delicious, but it was very, very soupy. I used Greek yogurt, so maybe that made it more watery? I scooped the chicken out of the baking dish using a slotted spoon to drain it and served it over spaghetti. My family LOVED it, but I’m looking for ideas regarding the soupiness.
Kristin says
So glad you enjoyed this!! The Greek yogurt does cause this to be a bit more soupy, however, the mayo does this slightly as well. The chicken and topping of this recipe release juices while cooking, causing this to have liquid in the dish. Scooping out the chicken is the best way to avoid getting the liquid on your plate. I typically cook the dish and then carefully drain some of the liquid prior to serving! Hope that helps 🙂

I’ve used mayo many times to coat chicken. I either dip it in bread crumbs after coating it. Or sprinkle it with a dried onion mix. I’m going to try your recipe now because I’ve never thought to mix in cheese. But, you have me thinking about using the mayo with olive oil.
I love a dinner you can throw in the oven and forget!
Kristin says
Great thinking on using the mayo with olive oil. I bet bread crumbs would be really good on this, now you have my brain thinking about varieties, haha!! 🙂
Rosemary says
You shoud never freeze mayonnaise…so I would say you could chop up the chicken ahead of tme and put in freezer bag and defrost chicken and add the rest of ingredients
Kristin says
Great suggestion! Thanks!! 🙂
Vikena G Thigpen says
I made this dish today and both my husband and I loved it. We were wondering if you could make it ahead, but not cook it and freeze thi dish. Then take out of freezer. thaw and then cook?
Kristin says
I don’t think the mayonnaise would freeze too good, may get too watery. One of the commenters above suggested cutting the chicken ahead of time to freeze and adding the other ingredients when you are ready to bake. I would follow that suggestion to avoid freezing the mayo. So glad you enjoyed it!! Its a new favorite in my house!!

Look at the picture before starting printing…
Some people… always blame others for their own stupidity……
Jade says
Have you made it both ways, with the mayo or yogurt? If so which did you prefer?
Kristin says
I have tried it both ways. Personally, I prefer the mayonnaise as it is much more flavorful, however, the yogurt is a nice change as well!

I chose “Printer Friendly” and selected one page. It printed page 1 of 7 and I didn’t even get the recipe!!!
Kristin says
If I remember right, I believe the recipe is on page 2, try printing that page. The intro and picture always bump the recipe to page two when I go to print it. Sorry about that!
Sheree says
To the lady with the complaint about the printer..Did you click on the link to make it printer friendly, because it brings you to a simple one page print. This does sound delish. Can’t wait to try it.
Kristin says
Thanks!! Let me know how it turns out!! Glad to hear the printer friendly link allows you to print just one page, phew!! 😉
Scott says
Is the chicken cooked or raw when you bake it for 30-35 min?
Kristin says
The chicken goes into this casserole raw, and in the 30-35 minutes, cooks through. Based on thickness of chicken, the time may need to be altered some 🙂
kori says
How did you make the noodles? I don’t know how to make noodles what so ever.
Kristin says
The pasta is just a boxed pasta that I cooked in boiling water until cooked al dente. I drained the water, added some olive oil and Parmesan cheese to the pasta, and served the chicken on top! 🙂
Kim says
I don’t consider 3 pages of BS and the recipe printing onto 2 pages — one with the picture and one with the ingredients– being printer friendly. NOT happy about my ink and paper being wasted.
Kristin says
I believe there is a box that allows you to opt out of certain things when printing? I am sorry for the inconvenience and will be sure to look into it. Hopefully I can fix that and allow the printing process to be easier 🙂
