Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 medium yellow onion, chopped
  • 2 cloves garlic, minced
  • 4 medium zucchini, chopped (about 6 cups)
  • 4 cups vegetable broth
  • 1 medium potato, peeled and chopped (for natural creaminess)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 cup raw cashews (optional, for extra richness)
  • Fresh basil or parsley 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 soft, about 5 minutes.
  2. Add the minced garlic and cook for 1 minute more until fragrant. Do not let the garlic burn.
  3. Add the chopped zucchini, vegetable broth, and chopped potato to the pot. Bring the mixture to a boil, then reduce heat, cover, and simmer for 15 minutes, or until the zucchini and potato are very tender.
  4. If using cashews, soak them in hot water for 5 minutes while the vegetables simmer, then drain them.
  5. Carefully transfer the soup mixture to a high-speed blender. Add the salt, pepper, and drained cashews (if using).
  6. Blend on high until the soup is completely smooth and silky. This may take 1-2 minutes depending on your blender. If the soup is too thick, add a splash more broth or water until you reach your desired consistency.
  7. Return the soup to the pot and heat through gently if needed. Taste and adjust seasoning.
  8. Serve your easy zucchini soup hot, garnished with fresh herbs. This recipe is also wonderful served chilled as a summer squash soup.

Notes

  • For a richer, dairy-free creaminess, the potato works well, but you can substitute it with 1/2 cup of soaked white beans for a similar effect.
  • If you prefer a traditional creamy zucchini soup flavor, stir in 1/4 cup of heavy cream or coconut milk after blending.
  • This soup freezes well. Cool completely before storing in airtight containers.
