Cover the casserole dish with foil and cook in the oven for 35 min.
Cook pasta al dente according to the box instructions
Remove foil and broil for another 5 minutes or until cheese is golden brown.
Your casserole dish will most likely look really soupy, this is okay, it's supposed to look that way!
Serve your pasta topped with chicken and a huge heaping of your sauce, don't forget some crusty bread to soak up all those good flavors.
Pro tip, feel free to ladel out a bunch of the liquid for dipping your bread, it is heavenly.
