I checked three different classic Italian cookbooks, and not one had a slow-cooked, meatless tomato sauce. Lots of variations on a theme, but I would venture not one would render this kind of a result. If you take the time to look at some of the higher end commercial marinara sauces on the market, named after famous chefs or restaurants, what you will find is this very short list of ingredients. The sauce in the jar will taste just like this sauce after you have cooked it for one hour. (At a cost of about $2 vs $8.95). But nothing out there will come close to this. You don’t have to buy the San Marzano Tomatoes, just a good imported Italian brand like Cento or Tutterosa.
4 28 oz cans crushed tomato with added puree
2 cans tomato paste
2 28 oz cans water
3 large sweet onions
10-15 cloves garlic
2 tbs fresh oregano leaves
4 tbs extra virgin olive oil
I like to put cooked meatballs in the sauce to simmer (but not raw ones, please). Partially browned and cooked Italian Sausage works, too. (Meaning it’s still pink inside.) This sauce will stick to any kind of pasta, but I prefer the large penne, either straight cut, or on the diagonal with the ridges the best. I would also use this sauce to make lasagna, eggplant or any baked dish.
It freezes well, and should yield about 4 quarts, enough for two very large family meals.
