Cauliflower Pesto Soup

It’s that time of the year again, y’all. Time for sweaters, scarves, and soup. While cold weather isn’t my favorite thing in the world (in fact-it’s probably my least favorite thing in the world), I do love the food associated with Fall. pumpkin flavors, squash, tomatoes, chili, and soup!

Cauliflower Pesto Soup

Slightly adapted from Isa’s Appetite for Reduction


1 teaspoon olive oil
4 cloves garlic, minced
1 head cauliflower, cut into florets
4 cups vegetable broth
1/2 teaspoon salt
Freshly ground black pepper
1 Tablespoon cornstarch
1 cup loosely packed fresh basil leaves, plus more for garnish
6 teaspoons pine nuts


Preheat stockpot over medium heat. Saute olive oil and garlic until fragrant, about 1 minute.

Add the cauliflower and 3 cups of broth (you’ll add the 4th later). Add salt and pepper to taste. Cover the pot and bring to a boil.

Let cook, stirring occasionally, for 10 minutes, until cauliflower is tender.

While this is cooking, preheat a small skillet over low heat. Add the pine nuts and stir often, until pine nuts are toasted and dark brown. Remove from heat.

In a measuring cup, whisk together the final cup of broth and 1 Tablespoon cornstarch. Lower the heat of the soup and bring it a slow boil. Mix in the cornstarch mixture and cover. Cook for another 5 minutes until soup has slightly thickened.

Add the basil leaves and pine nuts. Remove from heat.

Using a large food processor, process the soup in batches, allowing steam to escape. Puree until smooth. Add more salt and pepper to taste.

Serve soup garnished with basil leaves and more pine nuts, if desired.

Cauliflower Pesto Soup


Mmm. Cauliflower. Pesto. Warmth.

Fun fact about me, pesto is one of my favorite foods. This recipe is great because it’s 100% vegan and it’s low fat! That means the pesto isn’t oily, and there’s no heavy flavors of cheese in it.

The pureed cauliflower is a simple flavor, but with the basil, there’s a strong, somewhat spicy flavor to the mixture. My favorite part of the soup is that some of the cauliflower wasn’t totally pureed. Therefore, there were surprise chunks of cauliflower, cooked to perfection.

Have a great weekend!
