* PLUS Cooking time: 60 minutes


  • 3 large leeks
  • 3 large celery stalks
  • 2 large onions
  • 1 large carrot
  • 1 tbsp olive oil
  • 6 garlic cloves , minced, or 1 1/2 tsp garlic powder
  • 1 1/2 tsp dried oregano leaves
  • 1/2 to 1 tsp hot-red-chili-flakes
  • 1/2 tsp ground black pepper
  • 2 796-mL cans diced tomatoes , including juice
  • 2 cups vegetable or tomato juice
  • 1/2 cup chopped fresh parsley , optional


  • Slice off dark green portion from leeks and discard. Leave pale green-and-white portion intact. Slice in half lengthwise. Fan layers under cold running water to wash away sand. Then, finely chop. Thinly slice celery. Chop onions and carrot.
  • Heat oil in a very large saucepan set over medium heat. Add garlic and finely chopped vegetables. Cook, uncovered and stirring occasionally, until vegetables are hot and onion is soft, about 8 to 10 minutes.
  • Stir in oregano, hot red pepper flakes and black pepper. Add tomatoes, including juice, and vegetable juice. Increase heat to medium-high and bring to a boil, stirring occasionally. Then, reduce heat so sauce simmers. Cook, uncovered, stirring occasionally, until thick enough to coat pasta, about 1 hour. Stir frequently near the end of cooking to prevent sticking. When thickened, stir in parsley, if you wish. Sauce will keep well, covered and refrigerated, for up to 1 week or in the freezer for months.
