Vegan Leek and Cauliflower Soup Recipe

Vegan Leek and Cauliflower Soup

I made this soup the other day when I wanted something warm and hearty veggie meal. 

I must say I never realised that what a good combination cauliflower and leek can be! With lots of garlic of course. It’s so delicious! Throw in a potato to make it a bit thicker and you can use up the entire vegetables because they will be blended anyway. So don’t toss the cauliflower stalk and the dark green parts of the leek or even the potato skin! Just wash them and they will add some more flavour to the soup. A perfect zero food waste soup.

So I’ll be cooking this often when the veggies are in season now that I discovered what a lovely soup this Vegan Leek and Cauliflower Soup is and will be part of my extensive soup collection.

Also, can we just have a little more appreciation for cauliflower? Not only it is a very versatile (I do have a few cauliflower recipes!) but also practically contains 0 grams of fat and 5 grams of carbohydrates, so that’s 25 calories only. On the other hand, one cup of cooked cauliflower provides 73 to 77 percent of the recommended daily amount of vitamin C, 19 percent of the daily vitamin K amount and 8 percent of the daily manganese amount. (Leeks are good too, but cooking somewhat reduces their beneficial properties. They contain high levels of flavonoids, vitamins A, E, and K, and fibers).
