    Parmesan Chicken Casserole

    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!

    Equipment

    • Mixing Bowls
    • 9×13 baking pan

    Ingredients
      

    • 6 boneless, skinless chicken breasts, diced
    • 1 cup mayonnaise (or Greek yogurt)
    • 1 cup shredded Parmesan cheese
    • 1 teaspoon seasoning salt
    • ½ teaspoon ground black pepper
    • 1 teaspoon garlic powder

    Instructions
     

    • In a small bowl, combine the mayonnaise, ¾ cup Parmesan, seasoning salt, black pepper, and garlic powder. Set aside.
    • Place diced chicken into a greased 9×13 baking pan.
    • Spread mayonnaise mixture evenly on top of the chicken.
    • Sprinkle remaining Parmesan cheese on top of mayonnaise mixture.
    • Place baking pan in preheated oven, 375 degrees, and bake for 30-35 minutes.
    • Remove from oven and serve over pasta, rice, or by itself.

    Notes

    *Chicken will be a bit “soupy” from the liquid being released as it cooked. Use a slotted spoon to serve. 
    **Others have greased a cooling rack and placed the chicken on a cooling rack to “drain” liquid as it bakes. However you choose to try it, you’ll love it!

        Should work good! Make the sauce and spread it over the chicken. Put chicken in slow cooker on low for about 6-8 hours, or high for about 4 hours

      Okay, I hope you get as big a laugh out of this as I did. I read the recipe, (no glasses) so I added 1 cup parm cheese and 1 cup mayo. (WAY to much parm cheese) LOL… or so I thought. I worried the whole time it was cooking because I thought oh man that is going to be so gritty. but OMG it was so good! I will be making this a reg in my house. Not sure if I am going to downsize the parm or not it was that good!

      This was so easy and delicious. I cooked angel hair pasta, a la dente, tossed it in a tiny bit of coconut oil and seasoned with salt and pepper then put that in the bottom of the casserole. The raw bite size chicken went on top of that followed by the sauce. I used Greek yogurt plus the liquid on top of the yogurt for extra liquid for the sauce adding 1 tsp of crushed red pepper, parsley and basil. It was a perfect casserole. Adding broccoli or mushrooms would be a good twist. This would be an easy make ahead recipe.

      I haven’t experimented much but could you possibly brown the chicken for a short amount of time (not cooked through) with a bit of flour on it and then follow the instructions from there? The flour may turn soupy into a nice gravy plus the chicken wouldn’t have so much moisture in it to lose into the pan.
      Please let me know if this is a bad idea and why so I can learn.

      I wonder if using a baking rack in your baking sheet would allow the juice to drain through and therefore not be so soupy? Worth a try.

        That would definitely help, just make sure you grease the rack as I have tried it and the chicken stuck pretty bad to it!

      You know what you are still able to do these days? Use a pen and paper and copy the recipe down without printing it off a computer!!!! Another, more modern tip, I cut and paste the recipe text into an email and send it to my smart phone. I can then work straight off the phone in the kitchen. I had to laugh at the negative printer postings, some people aren’t happy unless they are unhappy lol

      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!

      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!!!
