Key Ingredients
Like I mentioned, a perk of this recipe is the simplicity of the ingredients–only 6 main ones! I bet you have most of these on hand…

- Cooked Chicken – Use rotisserie chicken as a shortcut or I included directions for how to cook your chicken ahead of time in the Cooking Notes in the recipe card below. You could also use chicken from our Roasted Chicken and Vegetables recipe or from Instant Pot Whole Chicken.
- Marinara sauce – You can make your own marinara sauce or use store bought. Choose the brand with the most recognizable ingredients. We recommend Newman’s Own or Rao’s brands.
- Shredded Parmesan and Mozzarella cheeses – Like our Baked Chicken Parmesan and Chicken Parmesan Sandwich, these cheeses add Italian comfort factor.
- Panko or whole wheat bread crumbs – Panko breadcrumbs will give it a great texture on top. You can also use regular homemade breadcrumbs (and even make them gluten-free, if needed).
- Fresh herbs – Fresh parsley (or basil) adds some additional flavor and color. You can substitute dried herbs from your pantry.

Reader Tip: Add Pasta
Several of our readers have said they add cooked pasta, such as rotini or penne pasta, as the bottom layer of the casserole with success.
We would suggest cooking pasta just until it’s al dente, so it doesn’t get too soft after baking. Also, make sure it gets coated in the marinara sauce so it doesn’t dry out.
How to Make Chicken Parmesan Casserole
This casserole comes together in 4 simple steps before either baking it or freezing it for later (see our freezing instructions below).
- Spray an 8×8 casserole dish with cooking spray. Preheat oven to 375°F.
- Add shredded, cooked chicken to the bottom. Then dump in a jar of marinara sauce. You can stir these together if you want, but it’s not a big deal if you don’t.
- Next, evenly distribute the shredded Parmesan and mozzarella cheeses.
- Lastly, top with the simple breadcrumb mixture.
- Bake for until hot in the middle and bubbly on the sides. Turn on the broiler at the very end for 1-2 minutes to help the breadcrumbs get toasted (watch closely so they don’t burn!).
See how simple this is to put together?




Here’s your final product after baking…

I’d suggest letting it cool and firm up a little bit before serving, about 10 minutes or so. You can garnish with fresh basil or even more chopped parsley for color.
How to Serve Chicken Parmesan Casserole
I almost always serve this casserole over cooked pasta. You could use penne, linguine, rotini, or really any type of noodle you have on hand. Chicken Parmesan Casserole can also be served over cooked brown rice. Lastly, it’s delicious if simply served by itself!
For a well-rounded meal, serve it with one of these side dishes:
- Skillet Green Beans
- Side salad topped with Honey Dijon Dressing
- Oven Roasted Broccoli
- Autumn Salad with Apple Cider Vinaigrette
- Cheesy Pesto Bread or Texas Toast

Freezer Meal Instructions
As with many of our freezer-friendly recipes, this casserole freezes wonderfully. A valuable use of your time in the kitchen is to double this recipe and a freeze an 8×8 dish for another dinner.
To Freeze: Simply assemble the casserole (with cooked chicken), do NOT bake, and then freeze it in an airtight freezer container.
To Prepare From Frozen: When you want to make it, thaw and bake it according to the recipe instructions. It might need to bake a little longer if it’s cold still.

FAQs
While mozzarella and Parmesan are the classic cheeses used in Chicken Parmesan, feel free to use other types. Try shredded Italian blend, asiago, or provolone in place of the mozzarella and grated Romano or even crumbled feta cheese in place of the Parmesan.
I have tested the casserole with raw chicken and it will get cooked through in about 20-30 minutes (be that a meat thermometer registers 165°F when inserted in the chicken). However, I’ve found that raw chicken releases a lot of liquid and can leave an unappetizing film behind in the dish. So, I recommend using fully cooked chicken instead.

Yes, you can freeze Chicken Parmesan Casserole. After prepping the casserole but before baking, wrap the dish in several layers of plastic wrap or foil, pressing out as much air as possible. Freeze for up to 3 months.
Yes, this casserole can be made gluten free by simply using gluten free breadcrumbs.

Chicken Parmesan Casserole
Ingredients
- 4 cups cooked chicken (shredded or diced; see Cooking Notes)
- 1 (24-ounce) jar marinara sauce
- 1/2 cup Parmesan cheese (shredded or grated)
- 1 1/2 cups shredded mozzarella cheese
- 1 cup Panko bread crumbs (sub: regular or gluten-free bread crumbs)
- 1 tablespoon olive oil
- 3 tablespoons fresh parsley (chopped; sub: fresh basil or 1 tablespoon dried parsley)
- salt and pepper (to taste)
Instructions
- Preheat oven to 375°F. Grease an 8×8-inch casserole dish with cooking spray.
- Layer the fully-cooked chicken in the bottom. Dump in the marinara sauce and mix with the chicken. Next, top with both cheeses until all the chicken is covered.
- In a small bowl, stir together the breadcrumbs, olive oil, fresh parsley, and a pinch of salt and pepper.
- Sprinkle the seasoned breadcrumbs over the top evenly.
- Bake on the middle rack for 25-35 minutes, or until hot in the middle and bubbling on the sides. Turn on the broiler for 1-2 minutes at the end to help it get brown on top (watch closely so it doesn’t burn!).
- Serve warm "as is" or over your favorite cooked pasta or rice.
Freezer Instructions
Notes/Tips
- Bake in Oven: Preheat oven to 400°F. Place chicken in a casserole dish or on a rimmed baking sheet. Bake uncovered for about 20-30 minutes, depending on the size of the chicken breasts.
- Slow Cooker: Place chicken in slow cooker. Cover and cook on LOW for 2 1/2 to 3 hours. Really! That’s all it takes to get it done, otherwise you’ll overcook and dry it out.
- Instant Pot: Place chicken and 1 cup chicken broth or water in a 6 quart Instant Pot. (Note: If using an 8 quart, add an additional 1/2 cup of broth.) Lock and seal the lid. Cook at high pressure for 7 minutes and use a quick release of the pressure when the cook time is up. (Note: It will take 10-15 minutes to come to pressure before the cook time starts.)
- Grill: Cut the chicken in half lengthwise so you have thinner pieces (this helps with fast and even cooking). Preheat grill to medium-high heat and clean the grates well. Grill for about 4-5 minutes per side, maybe longer depending on the thickness.

If I put this together tonight could I just keep it in the fridge until tomorrow? Or should I freeze it over night and put it in the fridge early in the morning?
It can stay in the fridge tonight for sure. No problem. You could leave the breadcrumbs off and put them on at the last minute to make sure they stay crisp, but you wouldn’t have to.
Made this tonight using gluten free bread crumbs and we all loved it. It was simple enough to just throw it all together with our pre-cooked chicken and bake.
Alright! Glad you enjoyed it!
This was AWESOME. I came home from work super late on a Monday night (the last Monday before Christmas break) and looked up easy recipes on Pinterest… This was perfect. I only used about half the amount of ingredients and didn’t use any breadcrumbs, but I can’t wait to make it again when I have more energy. Even with my lackluster effort, it was delicious and I’ll be eating the leftovers tomorrow over spaghetti squash. Next time, I’ll probably add kale or spinach and DEFINITELY make the full amount. Thanks for saving the day tonight… This was just what I needed. Can’t wait to make it again. (Btw: first time I’ve ever posted a comment, but I couldn’t resist.)
So glad you liked it and thanks for commenting! We love to hear from readers!
I made a couple pans of this for the freezer so haven’t eaten it yet. However, I used the canned parmesan instead of fresh and am wondering if you think that it will still taste okay? I am hoping I didn’t ruin it.
Oh it will be totally fine! It’s hard to mess this one up.
I made this and put in freezer and used the canned parmesan cheese…wondering if you think the canned will be okay? It didn’t specify and that was all I had on hand. Hoping I didn’t ruin it since I made two pans for the freezer.
I just want to say this was pretty darn good. I bought new chicken breast and cooked them for about 45 minutes on 350 and chopped them up after they cooled off. I honestly didn’t feel like buying and cutting up fresh herbs so I coated the chicken prior to cooking with salt and a healthy amount of Italian seasoning. I used a reduced-fat mozzarella cheese. After about 30 minutes in the oven, I switched the broiler on to brown the breadcrumbs (I used Italian breadcrumbs). I served whole wheat thin spaghetti on the side. My five year old son ate this up!! Last night it took him almost two hours to eat what I made off of Pinterest. I will make this again for sure!!
What kind/how much herbs do you use? I would use dry. Thanks!
Maybe a total of 1 teaspoon dried herbs, crushed in her hand.
Thank you.
Hello, I am going to make this on Tuesday and wondered if you used grated or shredded parmesan?
Also, a tip for anyone doing low carb – you can crush up pork rinds to make a breadcrumb-like topping. I’ve done this on another dish and it’s delicious!
Either kind works fine. I’m partial to the freshly grated just because it doesn’t have additives.
So, I made this about an hour ago. I read the recipe a little too fast and layered it in reverse. I put the cheese on top and the breadcrumbs under the cheese. I tasted it and thought it was still good. What are your thoughts?! Thanks:)
I say it’s hard to mess up this casserole! 🙂
Delightful and very versatile dish, you can pair it with almost anything!! I added some Dry sliced pepperoni from Fantino&Mondello to mine, gave a great twist to this recipe. Thanks again, I will without a doubt try more of your recipes!
This looks delicious! I’m going to try it tonight! My only question is, I don’t have marinara sauce, but I do have a pasta sauce that I can use. Do you think this will taste alright if I substituted the marinara with the pasta sauce?
I’m not quite sure what the difference is or if there is one…so yes, I think you’ll be just fine!
I doubled this recipe and have 3 roommate’s ..it was gone no left overs…yummy
I love that! Thanks for dropping us a line, Barbara!
Love it!
Hi! I was wondering how you cooked the chicken? Just in a pan with salt and pepper or did you bake it? Trying to think of easy ways to make sure the chicken is cooked! 🙂
Good question. There are several ways to cook chicken for a dish like this. 1) Boil it until no longer pink inside, but this will be the least flavorful. 2) Season with olive oil, salt, pepper, and any other seasonings you like. Bake chicken breasts or thighs at 350 degrees until no longer pink (usually 20-25 minutes), depending on the size. 3) Season and grill chicken breasts/thighs, until they reach an internal temp of 160 degrees. 4) Roast a whole chicken or two, which is the cheapest option. Here’s my favorite recipe: https://thrivinghomeblog.com/2012/05/healthy-roasted-chicken-and-vegetables-recipe/
How many servings does this make?
An 8×8 pan of this (what the recipe makes) serves 4-6.
This was super delicious! Everyone in the family loved it. It was also very easy to throw together.
Awesome! So glad it was a hit!
My family considers this a favorite recipe. I make large quantities of marinara sauce and store it in the freezer which comes in handy when making Chicken Parm. I’m not a “casserole” person so I wasn’t sold on the idea of Chicken Parm Casserole, but this casserole recipe somehow works. Thanks for sharing. It’s delicious!
It’s so great to hear that, Tammy! Thanks!
