Put mixture in a nonstick 9X11" casserole pan or spray your pan with some Pam first.
Sprinkle remaining cheese on top of casserole.
Bake uncovered in 375 degree oven for 1 hr. 15 minute to 1 hr. 30 minutes or until mixture is no longer soupy. If after one hour casserole is browned, you can cover with aluminum foil loosely for remaining time in oven.
