As Fall approaches, thoughts turn to warm and comforting food.

This creamy low-carb chicken mushroom soup is a lovely bowl of deep flavours and lush textures. It’s just what you need on a rainy day. It's like a hug from the inside.

You could even call this 'The Ultimate Anti Keto-Flu Soup' because it's packed with electrolytes, especially magnesium and potassium. This recipe makes four regular servings (served as a light dish) or up to eight servings (served as an appetiser). Enjoy!

How to thicken soup without flour

To keep this soup keto-friendly, we used xanthan gum to thicken the soup. However, if you are sensitive to this low-carb ingredient (tummy issues), you can swap the 1/2 xanthan gum for some of the following alternatives:

  • 1/2 to 1 tsp glucomannan powder. Use just like xanthan gum. Although the name may sound unfamiliar to some of you, it's the same ingredient that makes shirataki noodles (aka konjak noodles). Glucomannan powder is calorie-free and carb-free made with 100% fibre!
  • 4 to 6 egg yolks. Ideal when you make our popular keto bread and end up with leftover egg yolks — not to mention the keto buns would be fantastic as a side with the soup! To thicken the soup, simply reserve about 1 cup of the stock used in this recipe and whisk with the egg yolks. Slowly drizzle into the soup while stirring at the end of the cooking process. Cook briefly for 1 to 2 minutes to thicken.
  • Finally, you can easily thicken the soup by part-blending the ingredients! To do that, simply pour about a third of the soup into a blender and pulse until smooth and creamy Then add back into the pot with the soup. Alternatively, use an immersion blender. For even creamier results, blend with a few cooked cauliflower florets.
