Make this easy, creamy zucchini soup using fresh garden zucchini and potatoes for a velvety texture. This one-pot recipe is quick, healthy, and perfect for a light lunch or simple dinner.

Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 large yellow onion, chopped
  • 2 cloves garlic, minced
  • 4 medium zucchini, chopped
  • 2 medium potatoes, peeled and chopped
  • 4 cups vegetable broth
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 cup heavy cream (or full-fat coconut milk for vegan option)
  • 1 tablespoon fresh lemon juice
  • Optional garnish: Fresh basil, croutons, or Parmesan cheese

Instructions

  1. Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion and cook until soft, about 5 minutes.
  2. Add the minced garlic and cook for 1 minute until fragrant.
  3. Add the chopped zucchini, potatoes, vegetable broth, salt, and pepper to the pot. Bring the mixture to a boil.
  4. Reduce the heat to low, cover the pot, and simmer for 15 to 20 minutes, or until the potatoes and zucchini are very tender.
  5. Remove the pot from the heat. Use an immersion blender to blend the soup until it is completely smooth and velvety. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth, then return it to the pot.
  6. Stir in the heavy cream (or coconut milk) and lemon juice. Heat gently for 2 minutes, but do not boil.
  7. Taste and adjust salt and pepper as needed. Serve the creamy zucchini soup hot, garnished with your choice of toppings.

Notes

  • For a vegan zucchini soup, substitute heavy cream with full-fat canned coconut milk or a plant-based cream alternative.
  • If you want a richer flavor, sauté 1/2 cup of chopped leeks with the onion.
  • This recipe is excellent for using up abundant garden zucchini.
  • For a low-carb soup variation, omit the potatoes and add 1/2 cup of raw cashews (soaked and blended) for creaminess instead.
