We have always been fans of creamy tarragon sauces that seem to complement chicken and mushrooms so well. This recipe combines all those yummy elements in one delicious bowl, rich and luxurious and full of flavour.

We aren’t following a specific ‘diet’, but are trying to limit our carbohydrate intake, especialy on non exercise days. As a result a lot of the food we eat and my recipes are keto and low-carb friendly, and this is one of them.

I cook this soup in a slow cooker so I can make a huge batch to last us a few days. You can of course cook it on the hob as well (just adjust the timings), and reduce the quantities according to preference.

One of the secrets to why this soup is so amazing comes from the stock. I use homemade chicken stock which is already infused with the flavours of tarragon, lemon and garlic and it really helps to build the flavours and adds another dimension.

I cook a whole tarragon chicken in my slow cooker, then I make homemade chicken stock from the carcass overnight. The left over chicken meat also gets used in the recipe.

You can also use commercial chicken stock- just check the ingredients if you are on a low carb or keto plan. However, the extra effort at making your own stock really is worth it, and doing it in the slow cooker makes it super simple.
