Ingredients
- FOR THE PESTO:
- 50 grams (2 cups) fresh basil leaves
- 60 grams (1 cup) fresh parsley leaves
- 2 garlic cloves, peeled
- 30 grams (1/4 cup) blanched almonds
- 2 tablespoons nutritional yeast
- 4 tablespoons extra virgin olive oil (for pesto)
- FOR THE SOUP:
- 2 tablespoons olive oil (for soup base)
- 1 medium onion, finely diced
- 3-4 celery stalks, finely diced
- 2 large garlic cloves, finely chopped
- 0.5 grams (1/4 teaspoon) red chili flakes
- 3 cans (each 400 g / 14 oz) cannellini beans, drained and thoroughly rinsed
- 1000 ml (4 cups) vegetable stock
- 60 grams (2 cups) baby spinach
- Salt and freshly ground black pepper, to taste
Instructions
- Begin by preparing the vibrant pesto. In a blender or food processor, combine the fresh basil, fresh parsley, peeled garlic cloves, blanched almonds, nutritional yeast, and 4 tablespoons of extra virgin olive oil. Process until the mixture is completely smooth and creamy, scraping down the sides as needed to ensure everything is incorporated. Set this freshly made pesto aside.
- Heat 2 tablespoons of olive oil in a large, heavy-bottomed pot or Dutch oven over medium heat. Once shimmering, add the finely diced onion and celery stalks. Sauté for 5 to 6 minutes, stirring occasionally, until the onion becomes translucent and the celery starts to soften. This step builds the aromatic foundation of the soup.
- Add the finely chopped large garlic cloves and red chili flakes to the pot. Stir well and cook for just one more minute, allowing the aromatics to become fragrant. Be careful not to burn the garlic, as this can turn bitter.
- Incorporate the drained and thoroughly rinsed cannellini beans into the pot. Pour in the 1000 ml (4 cups) of vegetable stock. Stir everything together to combine the ingredients evenly, then bring the mixture to a gentle boil over medium-high heat.
- Once the soup is boiling, reduce the heat to low, cover the pot partially, and let the soup simmer for 10 to 15 minutes. This gentle simmering allows the flavors to meld beautifully and the beans to become even more tender, absorbing the richness of the broth.
- Remove the pot from the heat or keep it on very low. Stir in the prepared pesto until it is fully incorporated and "melted" into the hot soup, creating a rich, herbaceous swirl. Add the baby spinach and continue to stir gently for 1 to 2 more minutes, or until the spinach has completely wilted and turned a vibrant green.
- Taste the soup and adjust the seasoning with salt and freshly ground black pepper as needed. The nutritional yeast and pesto already contribute significant flavor, so season carefully. Serve the White Bean Pesto Soup immediately, perhaps with a drizzle of extra virgin olive oil or a sprinkle of vegan Parmesan cheese if desired.

Essential Success Tips
- Use fresh, high-quality basil and parsley for the brightest and most aromatic pesto flavor.
- Ensure the cannellini beans are thoroughly rinsed under cold water to remove excess sodium and any starchy residue, which improves the soup's clarity and digestibility.
- Do not overcook the garlic in the soup base; it can quickly become bitter if browned too much. A minute is usually sufficient for it to become fragrant.
- Add the spinach and pesto at the very end of the cooking process to preserve their vibrant color, fresh taste, and nutritional integrity.
- Taste and adjust seasoning meticulously before serving. A little extra salt or pepper can elevate the flavors significantly.
Professional Cooking Secrets
- To achieve a creamier texture without adding dairy, blend about 240-480 ml (1-2 cups) of the cooked soup with an immersion blender or in batches in a regular blender, then return it to the pot before adding the pesto and spinach.
- For an extra layer of nutty depth in the pesto, lightly toast the blanched almonds in a dry pan over medium heat for 2-3 minutes until fragrant before blending them.
- If you have a parmesan rind (and are not strictly vegan), you can simmer it in the vegetable stock for added umami and depth, removing it before adding the beans and pesto.
Notes
- Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop over low heat, adding a splash of water or stock if needed to loosen it.
- For an added textural element, serve the soup with crunchy croutons, a sprinkle of toasted pumpkin seeds, or a slice of warm, crusty bread.
- Feel free to customize by adding other quick-cooking vegetables like chopped zucchini, kale, or diced bell peppers along with the spinach for extra nutrients and color.
Frequently Asked Questions
Can I make the pesto ahead of time?
Yes, you can prepare the pesto up to 3 days in advance and store it in an airtight container in the refrigerator. To prevent browning, pour a thin layer of extra virgin olive oil over the surface of the pesto before sealing. Bring it to room temperature before adding to the soup for best results.
What if I don't have blanched almonds for the pesto?
You can absolutely substitute blanched almonds with other nuts like walnuts, pine nuts, or even cashews for a different flavor profile. If using unblanched almonds, you can quickly blanch them yourself by boiling them for a minute, then draining and slipping off the skins.
Is this soup freezer-friendly?
Yes, the White Bean Pesto Soup freezes well. Allow the soup to cool completely before transferring it to freezer-safe containers or bags. It can be stored in the freezer for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop, adjusting seasoning as needed.
