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.

- 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!).

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.
