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.

Super easy and very delicious.
Awesome! Thanks for the review Erin.
I’ve made this recipe about 5 times now. It comes together quite easily. This is now the only way I make chicken parmigiana. I have found with fully cooked chicken it makes the end result over cooked. Tonight I’m trying pan fried pieces that are only just browned. Hopefully that will make the chicken in the end not be so tough.
Thanks for the feedback, Lia. Using chicken thighs or rotisserie chicken can help with that issue, too.
Casserole was tasty, however, I need to cook the chicken one of the recommended methods. It was a little dry.
My daughter & I think this is truly a great recipe!
I’m so glad you both enjoy it!
This has become one of my husband’s favorite recipes. If it was up to him I would make it every week. I actually never make it with pasta. It is just a great low carb dinner without the pasta. Thank you so much!
So glad you found a winner for your family Joanne. That is a good tip to keep it low carb!
I’ve made this many times and both my husband and kids rave over it! It’s great over pasta, spaghetti squash or even plain. I’m going to try it tonight over cauliflower rice.
Hi Tiffany! Yes, I love the versatility of this dish. Thank you so much for taking the time to leave a review. I hope you love it over cauliflower rice too!
Been making this recipe since I discovered it. How long ago was that? I can’t remember. Making two batches to freeze tonight. Easy to make on a weeknight too. Just buy roasted whole chicken (I love BBQ roasted chicken), from the grocery store. Don’t have panko? Toast some bread, pop in the blender and you have your breadcrumbs.😋😋😋
Love you ladies. Thanks for this recipe.
Wow Edna, sounds like you’ve got this down pat indeed. Thank you so much for leaving a review with all your time-saving tips!
Putting it together this weekend – one of the pictures looks like 9×13 glass dish vs 8×8? What would you suggest?
Make it in an 8×8 inch as the recipe directs, or you can double it and make in a 9×13. Either works!
This is a great recipe! I rarely use “canned” sauces, but I used the brand they used, and I have to say, it was good enough to mark as a family keeper!! It is also really great as leftovers. We ate it alone with a side caesar salad.
Glad your family liked it!
Delicious and my family loved it!
Thanks for the review, Heather!
This is my go-to quick and easy dinner that everyone loves. I try to keep shredded chicken in the freezer to speed this along. I put it on pasta or rice.
Yes! Such a time saver to have cooked meat on hand. So glad your family loves it!
Can Boneless thighs be used instead?
Yes! Any cooked chicken will work. I often use leftover rotisserie chicken which is a mix of light and dark meat.
This is the second recipe I’ve tried from this blog, and both have been absolute winners! Very easy and so delicious!! The only thing I did differently was cook half a box of penne and mix it in with the chicken and marinara. So tasty! I’m testing recipes to stock up on freezer meals in preparation for our second baby. Other recipes I’ve tried from other sites have been hit or miss, either taking hours to put together or just not hitting the mark on flavor. This is the best of both worlds, and I’m loving you for it!!!
We’re thrilled to hear our simple recipes are working for you (especially pre-baby #2!). Love the tip to add in cooked penne! We really strive for our recipes to be family-friendly, fairly easy, freezable when possible, and made with real food ingredients.
Easy and yummy
Do you think I could use canned chicken in this recipe? And still freeze it?
I’ve never used canned chicken before, but I have used the pre-cooked frozen chicken. It wasn’t my favorite, to be honest, but it will work in a pinch. Rotisserie chicken is a great short-cut. The ones I’ve bought at the store usually yield about 4 cups of shredded chicken.
If you use a rotisserie chicken in the recipe, you can use the leftover carcass to make chicken stock and freeze it. I just throw the bones in a slow cooker, cover with water, toss in chopped onion, garlic, carrots, celery, fresh herbs like parsley or thyme…whatever you’ve got. Salt and pepper it some and let slow cook on low for up to 24 hours. Let it cool, strain it, and freeze in mason jars (leave 1 inch of head room at the top) or freezer containers.
Oh and yes you can definitely freeze it if using canned chicken. No problem there.
Had this tonight after thawing for 24 hours, and you’d never know it wasn’t made fresh! It was incredibly delicious, and the chicken was perfectly tender, cooked according to the recipe. The breaded topping is like the icing on the cake! This one was a homerun for sure. Make multiples to keep or share!
That’s what we love to hear–that a freezer meal tastes like fresh! That’s always our goal. Happy to hear this was a home run for you!
I made this wonderful, easy recipe to bake and serve my family; however, next time I’m going to double it. Bake one and freeze the other.
That’s great to hear you enjoyed it, Bobbie. Appreciate your review!
