Start by cooking the rigatoni. Boil it until it's a little less than al dente. Then drain the pasta. Combine it with 32 ounces of marinara sauce one one-third of the Parmesan cheese and one cup of mozzarella. Set this mixture aside.
Now let's prepare the chicken. Take some chicken breasts. Cut them into half-inch strips. Get three bowls for breading; one with flour mixed with salt and pepper another with beaten eggs and the last one with breadcrumbs. Coat the chicken strips in flour first then dip them in the beaten eggs and finally cover them with breadcrumbs.
It's time to fry the chicken! Heat a combination of vegetable oil and butter in a pan over medium-high heat. Fry the chicken until it turns brown on each side (4 minutes per side). Once cooked place the fried chicken on paper towels to absorb any oil. Then cut it into bite pieces.
Let's assemble our casserole now! Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish and start layering; begin with half of your cooked pasta mixture at the bottom of the dish followed by half of your chicken strips then sprinkle one-third of your Parmesan cheese on top along with one cup of mozzarella cheese. Repeat these layers using up all remaining ingredients.
Bake uncovered in your preheated oven for 25 minutes until everything is heated through and nicely melted together. If you prefer a crispier layer on your casserole you can increase the temperature to 425°F (220°C) for an additional 5 minutes during baking.
Once out of the oven garnish your Chicken Parmesan Casserole with some parsley, for added flavor and presentation.
Serve your casserole hot. Enjoy it ideally with a side of garlic bread topped with melted cheese!
That's it! You've now successfully made a Chicken Parmesan Casserole. Enjoy your meal!
