- 1/2 cup extra-virgin olive oil
- 1 small onion, chopped
- 2 cloves garlic, chopped
- 1 stalk celery, chopped
- 1 carrot, chopped
- Sea salt and freshly ground black pepper
- 2 (32-ounce) cans crushed tomatoes
- 2 dried bay leaves
- 4 tablespoons unsalted butter, optional
In a large casserole pot or Dutch over, heat oil over medium high heat. Add onion and garlic and saute until soft and translucent, about 5 to 10 minutes. Add celery and carrots and season with salt and pepper. Saute until all the vegetables are soft, about 5 to 10 minutes. Add tomatoes and bay leaves and simmer uncovered on low heat for 1 hour or until thick. Remove bay leaves and check for seasoning. If sauce still tastes acidic, add unsalted butter, 1 tablespoon at a time to round out the flavors.
If not using all the sauce, allow it to cool completely and pour 1 to 2 cup portions into freezer plastic bags. This will freeze up to 6 months.
