  • 2 tablespoon olive oil
  • 1 small onion finely chopped
  • 2 garlic cloves minced
  • 4 medium zucchini (1 ½ to 2 pounds) skin on, ends trimmed, halved lengthwise, and sliced
  • 3 cups vegetable or chicken broth or more as desired for a thinner texture
  • ¼ cup raw cashews
  • 1 teaspoon kosher salt
  • ¼ teaspoon ground black pepper
  • 2 tablespoons fresh lemon juice
  • 2 tablespoons chopped fresh herbs (dill, basil, or parsley work great), plus more for garnish


  • Heat the oil in a large pot over medium-high heat. Add the onion and saute for 4-5 minutes, until softened. Add the garlic, and stir for another minute.

  • Add the zucchini, broth, cashews, salt, and pepper, and bring to a boil. Turn the heat down to low, cover, and simmer for about 15 to 20 minutes, or until the zucchini is tender.
  • Add the chopped herbs and lemon juice to the soup. Then use an immersion blender (stick blender) to blend the soup until smooth, or transfer the soup in batches to a high-powered blender, and blend for just 15-30 seconds, until smooth.
  • Ladle portions of the zucchini soup into bowls and garnish with a drizzle of olive oil and fresh herbs.

  • This is my favorite immersion blender - it's so darn powerful!
  • I find that a high-powered blender tends to make this soup a bit smoother in texture, rather than an immersion blender. Both work great, it's really just up to you and your preference on texture.
