Mushroom soup in a bowl

Smooth mushroom and potato soup

I love mushrooms so I add them to dishes whenever possible as they suit well into pastas, omelettes, casseroles, etc. I had never tried to make mushroom soup until now as it usually doesn’t look too appealing. This smooth mushroom and potato soup recipe originates from a cookbook inherited from my late mom, so I just had to give it a go. And as it turns out, it is lovely.

But if you don’t love mushrooms like me, keep in mind that chestnut mushrooms have many good health benefits. One of the most important ones, for a freshly diagnosed coeliac, as per BBC goodfood: “Compounds in mushrooms, including beta glucan, appear to act as prebiotics, fuelling the growth of beneficial gut bacteria and promoting a favourable gut environment”. Mushrooms are also one of the few non-animal sources of vitamin D, when grown, exposed to ultraviolet (UV) radiation, either from sunlight or a UV lamp. So here’s to eating more chestnut mushrooms in 2022.

Not only is this delicious soup naturally gluten free, but also vegetarian and can be made vegan when substituting butter with a suitable alternative.
