Pistou soup, a beloved dish from Provence, France, is often considered the French cousin of Italy’s minestrone. It’s a simple yet hearty vegetable soup enriched with a robust, aromatic pistou-an herb paste that is the French answer to Italy’s pesto. Pistou soup is a perfect blend of fresh, garden vegetables, olive oil, and garlic, making it an ideal dish to enjoy in warmer months. It’s not just a meal, but a celebration of rustic French flavors that transport you straight to the sun-drenched Mediterranean coast.
What makes Pistou soup special? The pistou is the star of the show. Unlike pesto, which typically contains pine nuts, pistou is made with just garlic, basil, and olive oil. This simple but fragrant paste transforms the soup into a burst of flavor that’s simultaneously refreshing and satisfying. Whether you’re looking for a light meal or something more filling, pistou soup has the flexibility to serve both purposes.
This recipe is easy to customize and can be made to suit different dietary preferences. From the vegetable selection to the way you add the pistou, it’s a dish that allows you to be creative while sticking to its traditional roots.

Here’s the recipe for a classic, comforting pistou soup that’s perfect for any season, but especially spring and summer, when fresh vegetables are at their peak.
Ingredients Needed
- Olive oil (for sautéing and for the pistou paste)
- 1 large onion, chopped
- 2 medium carrots, peeled and sliced
- 2 zucchini, sliced
- 1 cup green beans, cut into 1-inch pieces
- 1 cup potatoes, peeled and diced
- 2 tomatoes, chopped (or 1 can of diced tomatoes)
- 4 cups vegetable broth (or chicken broth, if preferred)
- 1 bay leaf
- Fresh thyme sprigs (or 1 teaspoon dried thyme)

For the pistou:
- 2 cups fresh basil leaves (packed)
- 2 garlic cloves, peeled
- 1/4 cup extra-virgin olive oil
- 1/4 cup Parmesan cheese (optional, but highly recommended for an extra layer of flavor)
- Salt, to taste
Cooking Instructions
-
Prepare The Pistou
- In a mortar and pestle or food processor, combine the basil leaves, garlic, and a pinch of salt. If you’re using a mortar and pestle, gently grind the ingredients together. If you’re using a food processor, pulse them until finely chopped.
- Slowly drizzle in the olive oil while continuing to process or grind, creating a smooth paste. Stir in the Parmesan cheese if using, and set aside.
-
Start The Soup Base
- In a large pot, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion and sauté for about 3-4 minutes until the onion is soft and translucent.
- Add the carrots, zucchini, green beans, and potatoes. Stir for another 2-3 minutes to combine the vegetables.
-
Simmer The Soup
- Pour in the vegetable broth (or chicken broth), add the bay leaf, and toss in the thyme sprigs. Bring the soup to a boil, then lower the heat to a simmer. Let it cook for about 25 minutes, or until the vegetables are tender.
-
Add The Tomatoes And Pasta
- Stir in the chopped tomatoes (or canned diced tomatoes) and pasta. Let it simmer for an additional 10-12 minutes, or until the pasta is fully cooked.
-
Season To Taste
- Remove the bay leaf and thyme sprigs. Taste the soup and adjust the seasoning with salt and pepper if necessary.
-
Finish The Soup With Pistou
- Ladle the soup into bowls and swirl in a generous spoonful of the pistou paste. Stir to combine, allowing the pistou to infuse the soup with its garlicky, herbaceous goodness.
Ingredient Insights
-
Pistou Vs. Pesto
Pistou and pesto might look similar, but they are distinct. The key difference is that pistou omits the nuts found in traditional pesto. Instead, it lets the garlic and basil take the lead, with the olive oil acting as the binder.
-
Fresh Vs. Canned Tomatoes
When tomatoes are in season, use fresh for the brightest, most vibrant flavor. However, canned tomatoes can work just as well, especially when fresh tomatoes aren’t at their peak. Opt for high-quality, San Marzano or other Italian-style canned tomatoes for the best flavor.
-
Broth Choices
The broth is the foundation of the soup, so choose one that aligns with your flavor preferences. Vegetable broth is classic, but chicken broth offers a richer base if you prefer something heartier.
-
Pasta Choices
While the soup is often made with small pasta, feel free to get creative. Tubetti, farfalle, or even small broken pieces of spaghetti work well, as long as they cook quickly.
Expert Tips
-
Don’t Skimp On The Pistou
The pistou is the key element of this soup, so make sure to use fresh basil and high-quality olive oil for maximum flavor. If you have the time, make it ahead of time and let the flavors meld together.
-
Make It Ahead
Like many soups, pistou soup tastes even better the next day, after the flavors have had time to blend. Make a large batch and store it in the fridge for up to three days or freeze for longer storage.
-
Add A Protein Boost
If you’re looking to make this soup a bit more filling, add some cooked chicken, beans (such as white beans or chickpeas), or even a fried egg on top for extra protein.
-
Sauté The Vegetables For Extra Flavor
Taking the time to sauté the vegetables before adding the broth helps to caramelize their natural sugars and enhance the depth of flavor.
-
Finishing Touches
A drizzle of extra olive oil or a sprinkle of Parmesan cheese on top just before serving can elevate the dish even further.
Recipe Variations
-
Add More Greens
You can add other greens like spinach, kale, or Swiss chard to the soup. They’ll add a pop of color and extra nutrition.
-
Switch Up The Vegetables
Use whatever vegetables you have on hand-bell peppers, leeks, or eggplant all work wonderfully in this soup.
-
Spicy Pistou
For a spicy kick, try adding a chopped red chili to the pistou paste or sprinkle red pepper flakes into the soup as it simmers.
-
Vegan Pistou
To make this soup fully vegan, simply omit the Parmesan cheese from both the pistou and the soup itself. It will still be delicious!
Final Words
Pistou soup is a celebration of fresh ingredients, bold flavors, and simple techniques. It’s a dish that’s adaptable and forgiving, making it ideal for home cooks who enjoy putting their own spin on things while still staying true to tradition.

Can I Make Pistou Soup Vegetarian Or Vegan?

How Do I Make The Pistou For The Soup?
To make pistou, blend fresh basil leaves with garlic, olive oil, and a pinch of salt in a food processor or mortar and pestle. Optionally, you can add grated Parmesan cheese, but it’s not always included. The resulting paste is stirred into the soup just before serving, adding a fresh, aromatic kick.
Can I Prepare Pistou Soup Ahead Of Time?
Yes, pistou soup can be made in advance. In fact, the flavors often improve after sitting for a day. However, it’s recommended to add the pistou sauce just before serving to maintain its bright, fresh flavor. The soup can be stored in the refrigerator for 3-4 days or frozen for longer storage.
What Type Of Beans Can I Use In Pistou Soup?
Cannellini beans are the most commonly used beans in pistou soup, as they are creamy and absorb the flavors well. However, you can also use other white beans like navy beans or great northern beans. For a twist, you could use chickpeas or red beans, though they will change the flavor and texture slightly.
What Is The Best Pasta For Pistou Soup?
Small pasta shapes such as ditalini, macaroni, or tubetti are ideal for pistou soup as they hold up well in the broth and absorb the flavors. You can use other small pasta shapes, but it’s important to avoid large pasta that might overwhelm the soup’s delicate balance.
Can I Use Store-bought Pesto Instead Of Making Pistou From Scratch?
While pistou is similar to pesto, it is typically made without nuts and cheese. You can use store-bought pesto as a shortcut, but it may alter the flavor of the soup. If using pesto, try to find one with a simple ingredient list to maintain the authentic taste of pistou soup.
What Is The Best Way To Serve Pistou Soup?
Pistou soup is best served hot with a generous spoonful of fresh pistou stirred in just before serving. It can be accompanied by a slice of crusty French bread or baguette, which is perfect for dipping. A drizzle of extra virgin olive oil on top enhances the richness of the soup.
Can I Make Pistou Soup Gluten-free?
Yes, pistou soup can be made gluten-free by using gluten-free pasta. Be sure to check that all the ingredients, such as the broth, are gluten-free, as some store-bought varieties may contain gluten. The soup itself is naturally gluten-free if made with the right pasta and ingredients.
