Boil noodles in well-salted water until nearly al dente. Do not overcook.
Brown ground beef with Italian seasoning and drain.
Add Ricotta and Parmesan cheeses to the beef, along with one jar of the sauce, the egg, and salt and pepper.
Gently stir in the cooked, drained noodles.
Spread in large casserole dish.
Cover with second jar of sauce.
Sprinkle top with the Mozarella cheese.
Bake in 350 degree oven for 20-25 minutes. (We like it more well-done)
Top with chopped parsley and cook about 5 minutes more.
Let stand a few minutes before serving. I serve with a traditional green side salad.
