Key Ingredients & Substitutions
- Zucchini – Use fresh zucchini from your garden or local market. No need to peel your zucchini, but you will want to remove any seeds.
- Fresh basil – You’ll need a full, packed cup and a half of fresh basil for this recipe. Dried basil cannot be substituted – you won’t get the same fresh flavor.
- Other Vegetables – Russet potato is added to thicken the soup, while fresh carrots add some sweetness. Yellow onion and fresh garlic add a balanced savory flavor.
- Stock – We used vegetable stock to keep this soup vegetarian, but you can use chicken stock if you’d like.
- Fresh Mint – Don’t worry – this soup isn’t minty-flavored. The fresh mint enhances the fresh basil flavor.
- Seasonings – Kosher salt, freshly cracked black pepper, Worcestershire sauce and red pepper flakes all add additional savory flavors.
- White Wine – Used to deglaze the pan
- Sour cream – Whisked into the soup for more creaminess, plus a dollop is added to each serving
Special Tools Needed
- Medium Dutch oven or soup pot
- Cutting board and sharp knife

2 pounds zucchini (3–4 medium), ends trimmed, split and seeds removed then diced (see instructions below)
1/4 cup good quality extra virgin olive oil
1 cup russet potato, diced (about one small to medium Russet)
1/3 cup carrot, diced (about one small to medium carrot)
1/2 cup yellow onion, diced
2 teaspoons fresh garlic, minced
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
Pinch red pepper flakes
1/4 cup white wine
3 cups vegetable stock
1 1/2 cups fresh basil leaves, packed
2 tablespoons fresh mint, chopped
1/2 teaspoon Worcestershire sauce
1/4 cup sour cream, plus more to serve with each portion
- Trim the ends of each squash and split in half from one end to the other. Use a melon baller or spoon and scoop out seeds and discard. Cut into several long strips then cut the other way into small pieces and set aside.
- In a medium Dutch oven or soup pot, heat all of the olive oil over medium heat and once hot, add the potato, carrot and onion and stir frequently for five minutes. The potato pieces will want to stick so keep loosening up the bottom.

- Add the wine and stir to deglaze the bottom and evaporate the wine, about one minute.
- Add the vegetable stock and bring heat to bubbling, then lower to a medium simmer and cook uncovered for five more minutes.
- Remove from heat and puree with an immersion blender or a regular blender.
- Add all of the basil, mint, Worcestershire sauce and ¼ cup of the sour cream and puree to smooth.
- Taste and adjust seasonings if needed.
