Preheat oven to 425 degrees
Place cooked and cooled ziti in a large mixing bowl. Add the tomato sauce, Balsamella, mozzarella and grated cheese and stir to mix well. Place in a well oiled 9x13-inch casserole dish and sprinkle with bread crumbs and bake in oven until bubbling and crusty on top, about 30 minutes. Remove from oven and serve immediately.
For the Homemade Marinara Sauce:
In a large saucepan, heat the extra-virgin olive oil. Add the garlic cloves and cook over moderate heat, stirring occasionally, until golden, about 5 minutes. Add the tomato paste and cook, stirring, for 1 minute. Add the tomatoes; season with salt and pepper. Stir in the sugar and basil sprigs and bring to a boil. Simmer over low heat, stirring occasionally, until the sauce is thickened and reduced to 3 cups, about 30 minutes. Discard the basil sprigs and garlic.
For the Balsamella Sauce:
Melt the butter in a saucepan and whisk in the flour. Cook the flour mixture for a minute or two. Add in the milk, whisking all the while. Season with the salt and add in the nutmeg. Continue cooking over medium low heat, whisking and being careful that the mixture doesn’t scorch on the bottom of the pan. Cook until mixture begins to boil and thickens.
