I’ve always been a soup person. They are both easy to make, there are endless versions, they are perfect to make out of veggies that are turning old, they don’t require much time or effort from your end, they can easily be made in really big batches and they are both warming and comforting and can be made really healthy if preferred. If your not convinced yet I don’t know how to convince you that soup are one of the greatest foods we have! This is a cauliflower, potato and leek soup that is seasoned with lot of different spices to make it really flavorful and warming. It’s topped with fried mushrooms to add a nice chewiness and umami taste to the soup, dry roasted pistachio nuts for some crunch and fresh parsley. This soup really only takes five minutes to throw together and is both vegan, gluten free and healthy. It is perfect to serve as a starter or main course or to make for meal prep purpose.

A few tips:

  • I made my soup vegan, but you can use regular milk/cream if preferred.
  • The amount of spices can be adapted according to taste.
  • The amount of water, milk/cream can be adapted according to how thick you prefer your soup.
  • You can mix the soup completely smooth or leave some chunks depending on how you like it.
  • If you want to make this soup nut free you can replace the pistachio nuts with sunflower or pumpkin seeds instead.
