    How to thicken cauliflower soup

    I personally think the consistency of this cauliflower soup recipe is perfectly creamy and thick. The roux really helps to create that thick texture. However if you’d like to make the roasted cauliflower soup a little thicker, try adding 1 tablespoon of corn starch mixed with 2 tablespoons of cold water and stir into soup. Or add in a handful of cheese, which will help to thicken the cauliflower soup. You could even blend some of the vegetables up with an immersion blender, which will create a creamier consistency as well.

    Can cauliflower soup be frozen?

    Sure. If freezing, I would recommend either blending up the vegetables in the soup or under cooking them a little prior to freezing. Sometimes whole cooked vegetables can get mushy when reheating. Make sure cauliflower soup has cooled and store in an airtight container in the freezer for 1-2 months. To reheat, warm in the microwave or on the stove. If soup has thickened too much from freezing, feel free to add a splash of chicken broth to help thin it out a little.
