How to Make It
Brown ground beef in oil in a large skillet, stirring to crumble; drain off pan drippings. Stir tomatoes, tomato paste, and seasonings into meat. Bring to a boil; reduce heat and simmer 40 minutes, stirring occasionally.
Cook noodles according to package directions; drain.
Place half of noodles in a lightly greased 12 x 8 x 2-inch baking dish, slightly overlapping lengthwise edges. Spoon one-third of meat mixture over noodles; add half of shredded mozzarella, ricotta, and Parmesan cheese. Repeat layers, and spoon on remaining meat mixture. Arrange mozzarella slices on top. Bake at 350 for 30 minutes.
