What Makes Cauliflower Pesto Soup Creamy?

If you don’t like zucchini, don’t worry because you can’t even tell that the zucchini is in the soup. And I added milk and sour cream to make this cauliflower pesto soup extra creamy. The milk combined with sour cream gives the soup that creamy texture and still keeps the soup light and satisfying.


And I added grated parmesan cheese and an extra drizzle of pesto for the finish. This creamy cauliflower pesto soup is oozing with so much flavor. I especially love this soup with Nutritious Gluten-Free Flax Bread, or Gluten Free German Potato Bread.



What is pesto?

Pesto is typically made with crushed fresh basil leaves, olive oil, garlic, pine nuts and Parmesan cheese. But, there are many varieties of pesto. One of my favourites is the rich basil walnut pesto. I am not excited about pine nuts, but I love the earthy flavor of walnuts in pesto. But there are many pesto varieties.

You can switch up the greens to your liking by using your favorite greens, such as kale, cilantro, arugula, spinach, or parsley.

By replacing the pine nuts with other nuts or seeds such as almonds, pumpkin seeds, sesame seeds, or pistachios, you also change the tone of the pesto.

Add fresh lemon juice, sundried tomatoes, hot chili peppers, sour cream, or ricotta for flavor variations. There are many uses of pesto. Traditionally, pesto is tossed with pasta. However, you can use pesto for bruschetta toppings, over roasted veggies, with chicken or fish, stews, and naturally, in soups.

Pesto highlights your mains like no other flavoring. So feel free to create your pesto with your favorite ingredients next time you want to cook something extra special. If you are not into making fresh pesto, you can always buy ready-made pesto from your local grocery store. Just make sure it is gluten-free.
