Preheat oven to 350 degrees

In a bowl, combine ricotta cheese, 1/2 cup or the parmesan cheese, parsley, and oregano.

In the bottom of a 9 x 13 pan, spread 1 cup of the pasta sauce. Top with 4 of the lasagna noodles. You may need to break one of the noodles.

Spread 1 cup of the ricotta over the noodles. Then top with 2 cups of the pasta sauce followed by 2 cups of mozzarella cheese.

Repeat layers with the remaining noodles, ricotta mixture, sauce, and mozzarella.

Sprinkle remaining 1/4 cup parmesan over the top on the layers.

Cover with foil and bake at 350 degrees for 1 hour. Uncover, and bake for 10-15 minutes until noodles are tender. Let stand 15 minutes before cutting. Serves 12.
