Ingredients
1/2 cup extra-virgin olive oil
1 small onion, chopped
2 cloves garlic, chopped
1 stalk celery, chopped
1 carrot, chopped
2 (32-ounce) cans crushed tomatoes
4 to 6 basil leaves
2 dried bay leaves
Sea salt and freshly ground black pepper
4 tablespoons unsalted butter, optional
Preparation
In a large casserole pot, heat oil over medium-high heat. Add onion and garlic and sauté until soft and translucent, about 2 minutes. Add celery and carrot and season with salt and pepper. Sauté until all vegetables are soft, about 5 minutes. Add tomatoes, basil, and bay leaves and reduce the heat to low. Cover the pot and simmer for 1 hour or until thick. Remove bay leaves and taste for seasoning. If sauce tastes too acidic, add unsalted butter, 1 tablespoon at a time, to round out the flavor. Pour half the tomato sauce into the bowl of a food processor. Process until smooth. Continue with remaining tomato sauce. If not using all the sauce, allow it to cool completely and then pour 1 to 2 cup portions into plastic freezer bags. Freeze for up to 6 months.
