Roasted Cauliflower Soup

5 from 4 votes

Just a handful ingredients and you've got a creamy, nutritious soup.

After indulging in a few too many takeout lunches or pre-packaged dinners, many of us may be suffering from a load of refined and processed ingredients that inhibit our bodies’ abilities to perform at their peak. But a delicious, clean eating soup filled with veggies can be just the right medicine. These types of soup recipes have a detox effect on the body, helping us to rid our bodies of unwanted toxins and load up on quality ingredients.

Some cruciferous vegetables, like cauliflowers, have high amounts of antioxidant nutrients that help to provide a detoxifying effect. Cauliflower is not only high in antioxidants which fight cancer, keep your heart healthy, and boost your immune system, but it is one of the most fiber-rich veggies you can enjoy. Fiber is an excellent way to aid in a detox, and cauliflowers are brimming with it. Onion and rosemary provide beautiful flavor without excess calories, letting cauliflower take the spotlight in this detoxifying and delicious soup recipe.

This soup is astonishingly easy to prepare. Simply roast your cauliflower with a bit of salt, pepper, and extra virgin olive oil. Then combine your cauliflower with the rest of your ingredients in a pot, simmer, and blend with your immersion blender. We recommend purchasing an immersion blender if you don’t have one already. They are essential for well-blended soups and sauces, and so easy to use. You can find an inexpensive one easily, and start making deliciously creamy soups in no time!

    1. So sorry, we’re having some issues with some of the recipes showing up. We’re working hard to fix the problem. Please
      check back a little later. Thank you for your patience. 🙂

  1. already tried this soup and it tastes excelent!!!! I’m not a cauliflower fan but definitely I’ll make it again, also my mom wants to cook this recipe!

  2. This is a delicious soup. Roasting the cauliflower really bumps up the flavor. Used a Bayleaf instead of Rosemary. Also added lemon zest. Yummy!

  3. why is it 7 points? seems like the broth and olive oil are the only ingredients to have any point value.
