This is a lovely summer vegetable soup that my father discovered years ago from Wolfgang Puck (who was recounting a favorite recipe from his mother). It’s a French classic “Soup au Pistou” for which you gently cook very fresh summer vegetables in either water or stock, and stir in a paste (“pistou”) of basil, garlic, and tomatoes.

Dad makes the soup several times each summer, especially when the garden is producing a lot of summer squash and tomatoes! It’s a great way to use up garden produce.

Vegetable Soup with Sweet Basil Recipe

  • Prep time: 15 minutes
  • Cook time: 40 minutes
  • Yield: Serves 6

Note from Wolfgang Puck: His mother only uses water, because her vegetables are peak-of-the-season, just-picked, and therefore full of flavor, but you can use stock if you like. Pistou, the puree of tomatoes, basil, garlic, and olive oil in this recipe, is a traditional French condiment that adds a burst of flavor just before serving.

Ingredients

  • 2 small leeks, white part only
  • 1 large potato, peeled
  • 1 small onion
  • 2 stalks celery
  • 1 medium zucchini
  • 12 green beans
  • 2 medium carrots, peeled
  • 6 tablespoons olive oil
  • 3 tablespoons water
  • 2 quarts chicken stock (or 2 qts water, 4 bouillion cubes, a pinch of thyme, and 1/2 bay leaf OR you can use vegetable broth for a vegetarian option)*
  • 4 to 6 ripe tomatoes, peeled and seeded
  • 4 medium garlic cloves
  • 30 fresh basil leaves, washed and dried
  • Salt
  • 1/2 teaspoon freshly ground black pepper
  • A few drops of Tabasco sauce

*Use gluten-free stock or bouillon for gluten-free version.

Method

1 Cut the leeks, potato, onion, celery, zucchini, green beans, and carrots into 1/4 inch diced cubes.

2 In a 6-quart stockpot, combine 3 tablespoons of the olive oil with the 3 tablespoons of water. Add the vegetables and cook over medium-low heat until all the water evaporates. Do not brown the vegetables.

3 Add the stock to the pot and bring to a boil. Reduce to a simmer and cook for 30 minutes.

4 Meanwhile, make the pistou. Put the tomatoes, basil, garlic, and remaining 3 tablespoons of olive oil into a food processor. Pulse until puréed.

5 Stir the purée into the cooked soup. Do not let the soup return to a boil. Season, to taste, with salt, pepper, and a few dashes of Tabasco. Serve the soup hot or cold.

    Okay, so I know this recipe is a billion years old, but I had a bunch of leftover basil so I decided to make it. Delicious! I used homemade veggie stock and added parsnips (they were in the fridge looking left out) but otherwise followed the recipe. Thanks, as usual, for having simple and delightful food ideas!

    This recipe was simply delicious. I have shared it with friends, and it is always a hit. I sometimes add chicken. Other times I have added red bell pepper. I always add quite a bit of Tabasco sauce.

    Very good. Works well for a group whose tastes
    vary from those who like a bit of zing (add a generous serving of pistou, put the red pepper sauce on the table) and those who eschew all spiciness. We used fresh grated parmesan, too.

    I have made this recipe two or three times this summer and am making it again tonight with the last of the summer basil… it is so good and fresh. I find it needs a little extra salt and/or tomato paste if your tomatoes are less than stellar, but other than that, it’s excellent. I also add in a cup or so of fresh white corn.

    Frankly, I picked this recipe because I had a lot of tomatoes from our little garden and also some basil from my girlfriend’s garden. This recipe called for up to six tomatoes and thirty basil leaves. So I decided to cook this soup. It was delicious. I was afraid of all the basil; I had never eaten fresh basil before, but everything was perfectly balanced. Great soup.
