Cooking Instructions
This recipe is designed for simplicity without sacrificing flavor. The key is to layer your ingredients strategically to ensure even cooking and maximum cheesy, saucy distribution.
First things first, let’s get our pasta cooked. Bring a large pot of salted water to a rolling boil over high heat. Once boiling, carefully add the 16 ounces of penne pasta. Cook the pasta according to the package directions until it’s al dente, meaning it’s cooked through but still has a slight bite to it. We don’t want mushy pasta! As soon as the pasta is done, drain it thoroughly in a colander. While the pasta is draining, preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). It’s always a good idea to preheat your oven while you’re cooking other components so it’s ready to go when you are.
Now, let’s prepare our chicken. If your fully cooked breaded chicken strips aren’t already bite-sized, this is a good time to cut them into manageable pieces, about 1 to 1.5 inches in length. This will help them distribute evenly throughout the casserole and make it easier to serve. You can use kitchen scissors or a sharp knife for this. Ensure they are evenly sized so they cook at the same rate in the casserole.
It’s time to start assembling the base of our casserole. In a large mixing bowl, combine the drained penne pasta with the 32 ounces of pasta sauce. Stir gently until all the pasta is well coated with the sauce. Make sure there are no dry patches of pasta. This saucy pasta mixture will form the flavorful foundation of our casserole, so getting a good sauce-to-pasta ratio is important for deliciousness.
Now, let’s layer this masterpiece. Take a large, oven-safe baking dish, approximately 9×13 inches. Spread about half of the sauced pasta mixture evenly across the bottom of the dish. Over this pasta layer, strategically place about half of the bite-sized chicken pieces. Don’t worry about perfect placement; just aim for an even distribution. Then, generously sprinkle about half of the 20 ounces of shredded mozzarella cheese over the chicken and pasta. This cheesy layer is going to be a delightful surprise when you cut into the casserole!
We’re building towards that perfect cheesy crust! Now, repeat the layering process. Spread the remaining sauced pasta mixture over the first layer of cheese. Arrange the remaining chicken pieces on top of this pasta layer. Finally, and this is where the magic truly happens, top everything with the remaining 20 ounces of shredded mozzarella cheese and the 4 ounces of grated Parmesan cheese. Make sure to cover the entire surface with cheese for that irresistible, golden-brown topping. The combination of mozzarella for meltiness and Parmesan for sharp, nutty flavor is a classic for a reason!
Bake it until it’s bubbly and golden. Cover the baking dish tightly with aluminum foil. This will help the casserole heat through evenly and prevent the cheese from browning too quickly. Place the covered dish in your preheated oven and bake for 25 minutes. After 25 minutes, carefully remove the aluminum foil. This is where the magic happens – you’ll see the cheese start to bubble and melt. Continue baking for another 15-20 minutes, or until the cheese is gloriously golden brown and the sauce is bubbling around the edges. The aroma filling your kitchen will be absolutely divine!
The final, crucial step: let it rest. Once the casserole is out of the oven, resist the urge to dig in immediately. Let it rest for at least 10 minutes before serving. This resting period allows the casserole to set slightly, making it much easier to scoop and serve without everything falling apart. It also allows the flavors to meld together even further, creating a more cohesive and delicious final product. Serve hot and enjoy the incredible flavors of your homemade Chicken Parmesan Casserole! It pairs wonderfully with a simple green salad or some garlic bread.

It’s incredibly satisfying, relatively simple to prepare, and delivers a wonderful balance of tender chicken, rich marinara, gooey mozzarella, and savory Parmesan.

For serving, this casserole pairs beautifully with a simple side salad dressed with a light vinaigrette, some crusty garlic bread for soaking up any extra sauce, or even a side of steamed or roasted vegetables like broccoli or green beans. Looking for variations? You can easily swap out the chicken for eggplant for a vegetarian option, or add a layer of cooked pasta right into the casserole for an all-in-one meal. Feel free to experiment with different herbs in your sauce, like a pinch of oregano or basil, to personalize your Chicken Parmesan Casserole even further.
Frequently Asked Questions:
Can I make this Chicken Parmesan Casserole ahead of time?
Absolutely! This casserole is fantastic for meal prep. You can assemble it completely, cover it tightly, and refrigerate it for up to 2 days before baking. You might need to add a few extra minutes to the baking time if it’s going into the oven straight from the fridge.
What kind of chicken should I use?
Boneless, skinless chicken breasts or thighs work best. If using breasts, I recommend pounding them slightly to an even thickness for quicker and more consistent cooking. Thighs will result in an even more tender and moist casserole due to their higher fat content.
Can I freeze leftovers?
Yes, leftovers freeze wonderfully. Once cooled, portion the casserole into airtight containers or wrap individual servings tightly. It should keep well in the freezer for up to 2-3 months. Thaw overnight in the refrigerator and reheat gently in the oven or microwave.
