Slotted spoon
Blender (adult needed)
Pot holder


1 tablespoon olive or canola oil
1 unit onion, peeled and chopped
1 unit garlic clove, peeled and chopped
1 unit celery stalk, sliced
1 tablespoon chopped fresh basil (or 1 teaspoon dried)
2 unit (28-ounce) cans whole peeled or diced tomatoes, including the liquid

1 tablespoon vinegar (any kind is fine) or fresh lemon juice

Wash your hands with soap and water, then gather all your equipment and ingredients and put them on a counter.

  1. Put the pot on the stove and turn the heat to medium. When it is hot, carefully add the oil.
  2. Add the onion, garlic, celery, and if you are using dried basil, the basil. Cook, stirring occasionally, until the vegetables are tender, about 10 minutes.
  3. Add the tomatoes and their juice, and the broth. Raise the heat to high and bring to a boil.
  4. Turn the heat down to low and cook for 45 minutes. Set aside to cool for 15 minutes, stirring occasionally.
  5. Remove half the solids, using the slotted spoon, and put them in the blender. Do not fill more than halfway. Put the top on but remove the little cap in the center. Cover the hole loosely with a dish towel.
  6. Turn the blender to the lowest speed and increase the speed as the soup purees. Blend until smooth.
  7. Add the remaining solids and blend again. Gradually add the cooking liquid, fresh basil (if using), cheese, and yogurt.
  8. Serve right away, or cover and refrigerate up to 3 days.
