There may be no better way to use the most prolific vegetable of summer than to puree a whole lot of it into a soup. This zucchini soup has great body simply from the sheer amount of zucchini. There is no cream or starchy thickeners in sight. So it's both healthy (lots of vegetables) and efficient (as in using up all that zucchini gardeners tend to have on hand). This soup makes a nice lunch, a tasty start to a larger dinner, or the centerpiece to a light supper with crusty bread and a big summer or early fall salad served alongside.

If you also happen to have zucchini blossoms kicking around, they make a lovely garnish.

Ingredients

  • 1 medium onion
  • 1 tablespoon oil (or butter)
  • 1/2 teaspoon salt (plus more to taste)
  • 4 medium zucchini
  • 3 to 4 cups vegetable broth (or chicken broth)
  • Optional: dash black pepper (freshly ground)
  • Optional: dash nutmeg (freshly grated)

Steps to Make It

  1. Gather the ingredients.

  2. Trim, halve, peel, and chop the onion. Since the soup gets pureed, there's no need to be too precise about the chopping.

  3. Heat a medium pot over medium-high heat and add the oil or butter. When the fat is hot, add the chopped onion and the salt.

  7. Raise the heat to bring everything to a boil, and then reduce the heat to maintain a steady simmer and cook, stirring occasionally to keep things from settling too much, until the zucchini is very tender - about 15 minutes.

  8. If you have a hand-held immersion blender, this is a great time to pull it out and put it to use. Whirl the soup until it's extremely smooth. Whirl it for about twice as long as it seems you should and you'll end up with a much smoother, "creamier" soup.

  9. If you don't have a hand-held immersion blender, don't worry. Whirl the soup in a blender or food processor until very smooth (at least 1 minute per batch to make sure it's well and truly puréed). Be sure work in batches and to hold a kitchen towel over the top of the blender or processor (hot soup tends to splatter out a bit).

  10. Return the pureed soup to the pot. Add salt and pepper to taste (note that soup often requires a lot of salt to acquire good flavor, especially since there is naturally so much water in zucchini).

Tips

  • If you want the soup to be creamier in texture, there are a few quick additions that can achieve that goal. Add a bit of actual heavy cream and then simply stir it in and heat over low heat until the soup is heated through again before serving. Or, just dollop a spoonful of sour cream, Greek yogurt, or crème fraîche onto each bowlful.
  • This soup freezes beautifully, so feel free to make a double or triple batch and freeze any leftovers to enjoy when zucchini isn't in season anymore. It may be difficult to believe now, but you'll miss it!
