Even though we're not Italian, this rich, cheesy pasta dish is a family tradition for holidays and other special occasions. It tastes just like lasagna without the layering work. —Nancy Mundhenke, Kinsley, Kansas
Cook pasta according to package directions; drain. Crumble sausage into a Dutch oven. Cook over medium heat until no longer pink; drain. Stir in spaghetti sauce and pasta. In a large bowl, combine egg, ricotta cheese and mozzarella cheese.
Spoon half the pasta mixture into a greased shallow 3-qt. baking dish; layer with cheese mixture and remaining pasta mixture.
Cover and bake at 375° for 40 minutes or until a thermometer reads 160°. Uncover; top with Romano cheese. Bake 5 minutes longer or until heated through.
