I’ve always loved chicken Parmesan, but I also enjoy the convenience of casseroles. Cooked chicken, marinara sauce, diced tomatoes, cheese and pasta come together so easily with minimal cleanup in this recipe.
I used a panko breadcrumb and cheese topping, so you don’t have to worry about breading any chicken! 
How to Make Chicken Parmesan Casserole
It’s so easy! By using leftover cooked chicken (or store-bought rotisserie chicken) you’ll slash the time in this recipe.
Start out by cooking penne pasta (or any medium size pasta) according to package directions and drain (do your prep work while the pasta is cooking). Then you’ll stir together the cooked pasta, chicken, 2 cups of marinara sauce, diced tomatoes, 1 cup of mozzarella cheese, 1/2 cup of Parmesan cheese, Italian seasoning and pepper in a large bowl. Transfer to a baking dish and top with the remaining 1 cup marinara sauce. Cover with aluminum foil and bake for 30 minutes.
Remove the casserole from oven, remove foil and top with more mozzarella and Parmesan, then sprinkle with panko breadcrumbs. Return to oven and bake (uncovered) for 10 minutes, or until cheese is melted.
What to Serve with Chicken Parmesan Casserole
A garden salad and French bread have always been my go-to favorite sides with this convenient casserole.
Enjoy!

It came out absolutely delish! It’s now a family favorite for sure!
I didn’t have any Rotisserie or leftover chicken, but I had chicken thighs in the freezer. I baked those with the seasonings from the recipe and one of my secret ingredients, then cut it up as the recipe suggested. The flavor of the newly-baked chicken was divine! It was so good I actually passed out samples, which I rarely do. My daughter said, “We need to serve that as is with mashed potatoes and a great vegetable!” Duly noted!
