Make sure to gather your ingredients first. You will need olive oil, three finely chopped large onions, four cloves of crushed garlic, four kg chopped and peeled tomatoes, 2T brown sugar, and ⅔ cup shredded basil leaves.

To make the sauce, start by heating your oil in a large saucepan. Sautee your onions and garlic over medium-high heat, until translucent. This takes about two minutes. Stir occasionally.

Next, add the tomatoes and sugar. Mix everything together and turn the heat to low. Simmer the sauce for two hours. Stir occasionally.

Finally, remove the sauce from the heat. Season with salt and pepper, to taste. Mix in the basil and serve over your favorite cooked pasta or ravioli. Enjoy!
