Ravioli Casserole

1 jar spaghetti sauce
1 pkg. (25 oz.) frozen cheese ravioli, cooked and drained
2 cups small curd cottage cheese
4 cups shredded mozzarella cheese
1/4 cup shredded parmesan cheese

Spread 1/2 cup of spaghetti sauce in 9x13 pan. Layer with half of the ravioli, 1 1/4 cups of sauce, 1 cup of cottage cheese, and 2 cups of mozzarella cheese. Repeat layers. Sprinkle with the parmesan cheese. If freezing place in disposable aluminum pan. Cover with foil and freeze. Otherwise, bake uncovered at 350 degrees for 30 to 40 minutes or until bubbly. Let stand 5 minutes before serving.

***I used about 2/3 of a bag instead of the whole bag of ravioli. I used meat ravioli instead of cheese. I also did not cook the ravioli because I was going to be freezing the dish.
