This chicken parmesan casserole is a classic comfort food recipe that has been turned into an 5 ingredient weeknight dinner recipe that is perfect for families.
Cut up cooked chicken into bite-sized pieces. (See note 1)
Add penne pasta to boiling water and cook for about 9 minutes, until just short of al dente.
Drain pasta.
In a large bowl combine chicken, penne pasta, 16 ounces of mozzarella cheese, Parmesan cheese, and sauce (reserve about a cup of the sauce and set to side). Toss until ingredients are coated.
Pour mixture into a greased 9x13 inch casserole dish.
Add remaining cup of sauce to the top of the casserole and then sprinkle with remaining 4 ounces of mozzarella cheese.
Place in oven and bake for 30 minutes. You'll know it is done when the cheese on top is fully melted and the dish is heated through.
Remove from the oven and serve.
Notes
The chicken can be frozen chicken (fully cooked), rotisserie chicken (shredded), or chicken breast (fully cooked). It is up to you!
