This recipe for Low Fat Creamy Cauliflower Saffron Soup makes a delicate, soup with subtle flavors and velvety texture. Comfort in a bowl.

Pin This Recipe For Later!

I’ve made this wonderful cauliflower soup for lunch and served it with warm bread, (or if you’re feeling indulgent Perfect Garlic Bread)  but it also makes a fantastic starter for dinner parties as well.  A friend describes it as ‘A soup that will make you a cauliflower fan even if you’re not.’  Even kids love it!

Because it’s so bright in color, they don’t know it’s a vegetable soup and it’s a winner every time!

Why This Recipe Works

  • The addition of saffron to this basic cauliflower soup gives it a subtle flavor that can’t be beat!
  • Adding a potato to the soup instead of cream gives it a creamy texture without the added calories.
  • A little garlic helps flavor this soup without making it overpowering.

How to make low fat creamy cauliflower saffron soup

  1. Simmer the stock. Add saffron and steep.
  2. Heat olive oil in a pan, fry onions, and celery. Brown the garlic.
  3. Add the cauliflower and potato and stir.
  4. Pour in the stock and bring to a boil.
  5. Simmer until vegetables are tender.
  6. Blend until smooth.
  7. Serve and enjoy!

Albeit flavorful, this is a subtle soup. If you are looking for an intense soup with big flavors, this is not the soup you’re looking for, but I happen to find it elegant and delicious.

What is Saffron?

Saffron is a spice derived from the Crocus flower, also known as the “saffron crocus”. It has vivid red stigma and styles, called threads. These are collected and dried to use to flavor cooking. Saffron is the most expensive spice by weight. 

It’s well worth buying a good quality brand to use in your cooking, such as Mazaeus which is my favorite, as it’s rich in color and flavor.

To make this soup suitable for vegetarians simply swap the chicken stock for vegetable stock.

Make ahead and Freezing Instructions

  • To Make Ahead: This is one of those recipes that tastes even better a day after making it.  I often make it a day ahead, store it in the fridge overnight, and reheat it to serve.
  • To Refrigerate: Keep in the fridge for up to three days in a suitable airtight container.
  • To Freeze: Pour the soup into a freezer-safe, airtight container and freeze for up to three months.

    Hi Erren,
    wondering if you can provide a measurement in cups rather than “one rib of celery”, “one large onion”, “1/2 a potato.” I’m not a confident cook and that sort of thing is a little vague for me.
    Thanks

      Hi there! Thanks so much for your question – I totally understand how those measurements can feel a little vague. Here’s a breakdown in cups to help make things easier:

      1 large onion, chopped = about 1 ½ cups
      2 stalks (ribs) of celery, finely chopped = about 1 cup
      ½ medium potato, chopped = about ½ cup
      These don’t need to be exact – soup is very forgiving, so a little more or less won’t hurt the recipe. I hope that helps make it feel more approachable! 💛
      Enjoy the soup and thanks again for trying my recipe!

    Can this be done in a crockpot?

      I haven’t tried this personally, but you absolutely can!!
      Start by sautéing the onions, celery, and garlic in a skillet as per the original recipe. This step enhances the flavor, but if you prefer, you can skip it and just add everything directly to the crockpot.
      Add the sautéed onions, celery, garlic, cauliflower, potato, saffron threads, and chicken stock (or vegetable stock) to the crockpot.
      Cook on low for 6-8 hours or on high for 3-4 hours, until the cauliflower and potato are tender.
      Once everything is cooked, use an immersion blender directly in the crockpot to puree the soup until smooth. Alternatively, you can transfer the soup in batches to a blender.
      Season with salt and pepper to taste, garnish with chopped parsley, and serve.

      Please let us know how it turns out for you in the crockpot!😊

    It was ok. I had to add a lot of salt and pepper. Finally added 1/2 cup of heavy cream and that made it so much better.

    I had some broccoli left, didn’t know what to do with it and came across this recipe. It was delicious and very easy to make
    I added some mushrooms and garlic to it. I happen to love garlic and will add it to just about any dish.
    May I also point out a little Typo in the Instructions “Using a hand/stick blender blend the soup to your desired constancy” I think you meant to say “consistency”!
