Zucchini Soup/Vichyssoise is a perfect way to use up some of that zucchini in your garden! Choose the narrow ones which are more flavorful. Add a potato to the soup and turn it into a zucchini flavored, dairy free vichyssoise. Preparing Zucchini Soup/Vichyssoise without the potato gives you more of a zucchini broth. Both are delicious, and can be eaten hot or cold. Garnish with homemade croutons, fried zucchini, shredded raw zucchini or thinly sliced scallions.

The really large zucchini hold a great deal of water. If you do make this recipe with zucchini that resemble baseball bats, you will want to increase the salt, pepper, and dill, and add an extra potato. Keep tasting until you’re satisfied with the flavor.
