    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!

      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!!!

      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!

      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.

      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.
