There is nothing better than a bowl of satisfying soup on a cold winter's evening. This soup is deliciously rich and creamy with a spicy warming kick from the chorizo sausage and cayenne pepper.

I prefer it dairy-free but you can make it milder with some heavy whipping cream or cheddar cheese. One serving should keep you sated for hours but if you feel hungry, you can eat it with one of our Ultimate Keto Burger Buns!

  3. Dice the chorizo sausage. Peel and finely dice the turnip or use more cauliflower - the stems are great for browning. Place on a heavy-based skillet greased with the remaining ghee and cook over a medium-high heat until the chorizo is crispy and the turnip is tender for about 8-10 minutes.

  4. Transfer half of the chorizo & turnip mixture into the soup. Using a hand blender, pulse until smooth and creamy. Season with salt and cayenne pepper. Optionally, you can add 1 cup of heavy whipping cream or grated cheddar cheese. Low-Carb Spicy Cauliflower Soup

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Made this tonight, used cottage cheese, and added some spirulina powder to give the soup a healthy kick and a nice green colour. Thanks for the recipe!

Thank you Adrian, glad you liked it! What an interesting idea to add spiralling, I'm wondering if you can taste it? 😊
