Step‑by‑Step Instructions for Pistou Soup
Step 1: Prep Vegetables
Start by dicing the potatoes, slicing the zucchini, carrots, leek, and celery, and chopping the onion. Aim for uniform pieces to ensure even cooking. Lay everything out on a clean cutting board to keep your workspace organized. This preparation stage is essential in making your vibrant Pistou Soup come together seamlessly.
Step 2: Sauté Onions and Leeks
In a large pot, heat 2 tablespoons of olive oil over low heat. Add the chopped onions and leeks, cooking them gently for about 8 minutes until they become softened and translucent. This process enhances their sweetness and creates a flavorful base for your Pistou Soup. Stir occasionally to prevent them from browning.
Step 3: Brown Vegetables
Increase the heat to medium and add another 2 tablespoons of olive oil to the pot. Toss in the zucchini, diced potatoes, carrots, and celery, cooking for 3 minutes without stirring initially. Letting the vegetables brown slightly contributes to the soup’s depth of flavor. After 3 minutes, stir to combine and continue cooking for another minute.
Step 4: Simmer Base
Next, incorporate the sautéed onions and leeks into the pot along with 8 cups of water. Add the dried thyme, stir everything together, and bring the mixture to a low boil. Once boiling, reduce the heat and simmer uncovered for about 15 minutes, allowing the vegetables to soften while infusing the broth with delicious flavor.
Step 5: Add Green Beans
Raise the heat to bring the pot back to a boil, then add the green beans. Allow them to cook for 8 minutes, maintaining a lively simmer. This step ensures the green beans retain their vibrant color and crunch, contributing to the overall texture of your Pistou Soup.
Step 6: Incorporate Peas and Beans
Toss in the green peas and cannellini beans (including any liquid) into the simmering soup. Stir well and let everything simmer for another 2 minutes. Before removing the pot from the heat, season generously with salt and pepper to your taste, enriching the final flavor of your Pistou Soup.
Step 7: Prepare Pistou
In a food processor, combine the fresh basil leaves, garlic, and grated Parmesan cheese to create a chunky paste. As you blend, slowly drizzle in extra virgin olive oil until the mixture is smooth and well combined. This aromatic pistou is the soul of your Pistou Soup, enhancing its vibrant taste when added.
Step 8: Serve
To serve the Pistou Soup, ladle it into bowls and add a small amount of cooked elbow pasta, if desired. Top each bowl with a generous teaspoon of the freshly prepared pistou, swirling it into the soup just before eating. This method preserves the lush aroma of the basil, ensuring every bite is a delightful experience.

How to Store and Freeze Pistou Soup
Fridge: Store leftover Pistou Soup in an airtight container in the fridge for up to 3 days. Keep it tightly sealed to retain moisture and flavors.
Freezer: For longer storage, freeze the soup in portions for up to 1 month. Use freezer-safe containers, leaving some space for expansion.
Reheating: When ready to enjoy, thaw the soup in the fridge overnight, then reheat gently on the stove until warm. If the soup has thickened, add a splash of water or broth.
Pasta Note: If you’ve added pasta, consider cooking it separately when reheating to prevent it from becoming mushy during storage.
Make Ahead Options
Preparing Pistou Soup in advance is a fantastic way to save time during busy weeknights! You can chop your vegetables (potatoes, zucchini, carrots, leek, and celery) and store them in an airtight container in the refrigerator for up to 3 days. The soup base can also be made ahead—just follow the first six steps, let it cool completely, and then refrigerate for up to 3 days. When you’re ready to serve, simply reheat the soup, add the green peas and cannellini beans for the final minutes of cooking, and make your fresh pistou. This ensures every spoonful is just as delicious, fragrant, and comforting as the day it was made!
