Cream of roasted cauliflower soup (vegan)


Last Updated on March 10, 2020

I’ve named my recipe roasted cauliflower soup, but of course I don’t mean that the soup is roasted, but the cauliflower. This is the most important part of this easy soup recipe.

This vegan dish is full of natural flavors that come together in a creamy and very easy to cook cruciferous vegetable soup. When you roast the cauliflower, its nutty flavor unfolds its full potential. In order to get a deep aroma, you should not miss this important step. I have also used a flavorful spice mixture of thyme, nutmeg and cayenne pepper for this delicious soul food.

Low in calories, yet rich in nutrients

This great recipe lasts for 3 – 4 portions. You can also eat some salad as starter or pair the soup with slices of whole grain bread.

And when I say low-calorie, I mean 236 calories for a large plate of cauliflower soup. But I only managed one full bowl, because the soup is really rich and satisfies very well. If you are anyone who counts calories and still want to get full then you have found the solution.

Roasted cauliflower tastes fantastic

If you’re not a big cauliflower fan, try it roasted. I’ve seen people adding parmesan cheese but you really don’t need it. Oven roasting alone turns the white vegetables into an incredibly delicious food.

Because the edges caramelize with a little salt and the cauliflower tastes sensationally awesome. To turn the soup into a creamy delicacy you have to just purée the ingredients in a blender or food processor. Done!

By the way, the soup is not only vegan but also gluten-free. The following recipe is sufficient for 3 – 4 portions, but you can easily double it.
