- Potatoes: To help thicken the soup and make it extra velvety without adding dairy, like heavy cream, or nuts, such as cashew cream.

Sauté your onions.
Take advantage of this step! Sautéing your onions in extra virgin olive oil is one of the things that gives this soup its exceptional flavor.
Use good quality unsalted vegetable stock.
A good quality vegetable stock or broth will add depth and complexity to the soup, making it more flavorful. Opt for unsalted or low-sodium stock so you can control the amount of salt that goes into your dish.
Blend away!
This is not the time for chunky soup. Once blended, both cauliflower and potatoes create a super smooth and creamy texture that’s just so comforting.

What are the Potential Health Benefits of Cauliflower?
1Cauliflower is an Anti-Inflammatory Food
The antioxidants in cauliflower, such as sulforaphane, can protect the body’s cells from damage caused by oxidative stress. As a result, cauliflower may play a role in reducing inflammation in the body1.
2Cauliflower Can Support a Healthy Immune System
Due to its high levels of vitamin C, cauliflower has the potential to support the immune system and reduce susceptibility to infection2.
3Cauliflower May Play a Beneficial Role in Weight Loss and Obesity Prevention
Cauliflower is high in fiber, a beneficial nutrient in many ways. Not only does it feed the healthy bacteria in our gut and improve digestive health, but it also slows digestion and promotes fullness. A benefit that can help us to reduce our overall calorie intake throughout the day3.
4Cauliflower has the Potential to Support Heart Health
Along with folate, the choline in cauliflower can help reduce the amount of homocysteine accumulating in the blood, a well-known risk factor for heart disease4.
