Creamy Zucchini and Leek Soup with Kefir
The first time I truly understood that 'creamy' didn't have to mean 'heavy' was on a rainy afternoon in a small cottage near Haapsalu, visiting my friend Liina. We came in from a walk, chilled and damp, and she put on a pot of this soup. I watched, expecting cream to be added at the end, but instead, she reached for a bottle of plain kefir. She explained that boiling it would destroy its benefits, so she stirred it in gently off the heat. The kefir transformed the soup, giving it a bright, tangy dimension and a silky texture without any of the weight. That day, I learned a fundamental secret: nourishment and indulgence can be the same thing. This soup is proof of that beautiful lesson.
12Ingredients

Nutrition Facts
Instructions
Heat the olive oil in a large pot or Dutch oven over medium heat. Add the leek and onion and cook, stirring occasionally, until softened and translucent, about 8-10 minutes. Don't let them brown.
Add the minced garlic and cook for another minute until fragrant.
Add the chopped zucchini, cannellini beans, vegetable broth, salt, and pepper. Bring to a boil, then reduce the heat to a simmer. Cover and cook for 15 minutes, or until the zucchini is very tender.
Remove the pot from the heat and let it cool slightly for a few minutes. Using an immersion blender, blend the soup directly in the pot until completely smooth and velvety. Alternatively, carefully transfer it in batches to a regular blender.
0Once blended and no longer piping hot, gently stir in the kefir until fully incorporated. Taste and adjust seasoning with more salt and pepper if needed.
0Ladle the soup into bowls. Garnish with a sprinkle of toasted pumpkin seeds, fresh dill, and an optional drizzle of extra virgin olive oil before serving.
0Chef's Tip
The key is to add the kefir when the soup is warm, not boiling hot. This preserves the live probiotic cultures and prevents the kefir from curdling, ensuring a perfectly smooth texture.
