Wow—so good!” What You’ll Need To Make Creamy Zucchini Soup Olive oil, yellow onion & garlic cloves: The flavor base of the soup; a little olive oil also gets stirred in at the end to add body and bring everything together. Zucchini: This versatile veggie cooks down to form a bright base and gives the soup its fresh flavor and pretty green color. (No need to peel it.) Chicken broth: The base of the soup. If you’d like to make the soup vegan, use vegetable broth instead of chicken broth. The soup’s already dairy-free, so this one swap makes it plant-based. Dill & lemon juice: Fresh dill gives a fresh herbal note (either fresh or dried will work), and a squeeze of lemon at the end brightens the whole bowl. Walnuts: Toasted to bring out their flavor and pureed into the soup, walnuts thicken things up and give the soup a creamy, texture without the need for dairy.

Jump to the printable recipe for precise measurements Step-by-Step Instructions Step 1. Sauté the aromatics. In a large pot, heat 2 tablespoons of olive oil over medium-low heat. Add the chopped onions and garlic, and cook until the onions are soft and translucent. Step 2. Simmer the zucchini. Add the sliced zucchini, chicken broth, salt, and pepper. Bring to a boil, then cover and simmer for about 10 minutes, or until the zucchini is tender. Step 3. Toast the walnuts. While the soup simmers, toast the walnuts in a 350°F oven for 5 to 10 minutes, until fragrant. (Keep a close eye on them as nuts can burn quickly.) Step 4. Purée the soup. Add the toasted walnuts and chopped dill to the pot. Use an immersion blender to purée the soup until completely smooth, or work in batches using a regular blender. Pro Tip: If you’re using a blender, be sure to crack the lid slightly or remove the center knob and cover with a kitchen towel to allow steam to escape—hot soup expands fast and can be messy (and dangerous) in a sealed blender. Step 5. Add lemon and oil. Stir in the lemon juice and remaining olive oil, then taste and adjust the seasoning as needed. Ladle into bowls, drizzle with more olive oil, and sprinkle with dill. Feel free to top it off with croutons as well. The soup will keep well for several days in the refrigerator; freeze for longer storage.
