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!

What else was put on here? Looks like parsley or something. There is no green space in the ingredients
Kristin says
Yep, just some dried Parsley for added color 🙂
it isn’t required and doesn’t change the flavor any, so I omitted it from the recipe 🙂
Lisa says
If you are having trouble printing the recipe just copy and paste it into a word document and print it from there.
Kristin says
Great idea!! Our print feature was having glitches this past week, but just went through an update, so hopefully its better now!
Judy says
can this be done in a crock pot
Kristin says
I am hoping to attempt that this week, we’ll see how it works out! Fingers crossed as that would make this recipe even easier, 🙂
Laura says
Could this be made in a slow cooker? It sounds delicious!
Kristin says
I have not tried that yet, but that is my next trial run of this. I am hoping it works as that would be even easier!!
natalie says
Not sure how the recipe will be but I will not be using anymore of your recipes if printer friendly means 11 pages for a recipe that should fit on an index card. Please fix the print feature.
Kristin says
Sorry to hear so many pages printed out, I will look into it! Thanks!

This was absolutely delicious. I was in a hurry so just fried up the chicken and added the rest in the frying pan. It was so fast and easy. I used regular plain yogurt which also made it a healthy meal choice.
Kristin says
So glad you enjoyed this!! Definitely a tasty, quick meal!!

A copy and paste into a clean page always works and avoids any graphics or other content you’d rather not print. Easy to save to your own recipe file.
Kristin says
Thanks for the tips!! Hope you enjoy this recipe 🙂
Cathy says
Hi, I made the recipe last night and it turned out delicious! I was wondering if it would be OK to freeze it (made with mayo) after it has been cooked!
Kristin says
Sure! As long as you have cooked it prior to freezing, it should be just fine! It may be a little liquidy when thawed, but just use a slotted spoon when serving, to drain the juices! So glad you enjoyed this!!
Lori says
Could you place a baking rack in the bottom of your pan and place the chicken on it? This would keep the chicken out of the soupy juices. You could then lift rack out and put chicken on a serving plate or on top of you pasta,rice or whatever you are serving it on.
Kristin says
That’s a great idea! I don’t see why that wouldn’t work perfectly! I will have to try that next time!
Corinne says
Like the recipe. I was wondering if I can use miracle whip instead of mayo? That is what I have always used not mayo. Just wondering if anyone has done this. Tia Corinne
Kristin says
Yep, that should work just as well!! Let me know if you try it and what you think!!
cindy says
Drain the yogurt first though cheesecloth to avoid the soupy texture. The yogurt will release a lot of water that will not end up in your dish.
Kristin says
Great tip!! Thanks!
Sarah says
I made this using greek yogurt & it was very soupy! Also didn’t get browned like the picture. It tasted good, though!
Kristin says
The moisture from the yogurt and chicken does make this have a lot of liquid. I recommend using a slotted spoon to serve this, so the liquid stays in the pan. It keeps the chicken moist, and the liquid off your plate 🙂
Glad you enjoyed it!

Tried it tonight – it was wonderful!! I used chicken thighs instead of breast meat because we like dark meat. Had it with rice and roasted Brussels sprouts. Thank you!!!
Kristin says
So glad you enjoyed it!! Sounds like a yummy dinner!! 🙂
Paula says
This looks great and easy for a working Mom to put together for a family meal. I can’t wait to try it tonight. Thank you for posting. Sorry some folks are always so negative. Wish folks would adhere to “if you can’t say something nice, don’t say anything.”
Kristin says
Thanks! This definitely is the perfect dinner for a working mom!! Hope you enjoy it!! Keep me posted if you try it 🙂
Have a great day!
