In a large oven proof pan or 10 inch skillet, add 2 tablespoons olive oil and ground beef, brown, then add tomato puree, salt, basil, oregano, garlic and water stir to combine, add basil leaves and cook on medium heat, half covered until thickened (approximately 20-25 minutes).
While sauce is cooking. In a large pot of boiling salted water cook pasta al dente, drain.
When sauce has thickened, add drained pasta and mix well to combine. Drizzle 1/2 cup of white sauce** and top first with diced mozzarella and then parmesan cheese. Bake for approximately 20 -25 minutes in a preheated 350° (180°) oven. Top with extra Parmesan if desired. Enjoy!
Either homemade White Sauce or a good store bought if you prefer.
