Make this quick, healthy zucchini soup for a comforting meal. We use simple ingredients to achieve a silky smooth texture in under 35 minutes, perfect for a light lunch or weeknight dinner.

Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 medium yellow onion, chopped
  • 2 cloves garlic, minced
  • 4 medium zucchini, chopped (about 6 cups)
  • 1 medium potato, peeled and chopped (for creaminess)
  • 4 cups low sodium vegetable broth
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 cup raw cashews or 1/2 cup cooked white beans (for optional creaminess boost)
  • 1 tablespoon fresh lemon juice (optional)

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.
  4. Bring the mixture to a boil, then reduce heat, cover, and simmer for 15 to 20 minutes, or until the zucchini and potato are very tender.
  5. Remove the pot from the heat. If using, add the raw cashews or cooked white beans.
  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, blend until no grit remains.
  7. Return the soup to the pot if necessary. Stir in the fresh lemon juice, if using. Taste and adjust salt and pepper as needed.
  8. Serve the soup warm. This is a great healthy garden vegetable soup for any season.

Notes

  • For a richer, dairy-free creaminess, soak cashews in hot water for 15 minutes before blending. Drain them before adding to the soup.
  • This recipe works well as a make ahead soup recipe; cool completely, then store in an airtight container in the refrigerator for up to 4 days.
  • If you prefer a heartier meal, add cooked Italian sausage when serving.
