Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 medium yellow onion, chopped
  • 2 cloves garlic, minced
  • 3 large zucchini, chopped (about 6 cups)
  • 1 medium potato, peeled and chopped (for natural creaminess)
  • 4 cups vegetable broth
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 cup raw cashews, soaked in hot water for 15 minutes (optional, for extra richness)
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion and cook until softened, about 5 minutes.
  2. Add the minced garlic and cook for 1 minute until fragrant.
  3. Add the chopped zucchini, chopped potato, vegetable broth, thyme, salt, and pepper to the pot. Bring the mixture to a boil.
  4. Reduce the heat, cover, and simmer for 15 to 20 minutes, or until the zucchini and potato are very tender.
  5. If using cashews, drain them now.
  6. Carefully transfer the soup mixture to a high-speed blender, or use an immersion blender directly in the pot. Blend until completely smooth and silky. If using cashews, add them now and blend until fully incorporated.
  7. Return the soup to the pot if necessary, and heat gently if it has cooled. Taste and adjust salt and pepper as needed.
  8. Serve your healthy zucchini soup hot, garnished with fresh parsley.

Notes

  • For a vegan zucchini soup option, confirm your broth is vegetable-based.
  • If you prefer a richer texture without cashews, substitute 1/2 cup of the cooked zucchini with 1/2 cup of cooked white beans.
  • This soup freezes well for easy meal prep. Cool completely before storing in airtight containers.
  • For a different flavor profile, try adding 1/2 cup of chopped leeks along with the onion.
