Rustic Mushroom Soup with Thyme

Soup season has finally arrived and one of my favourite soups is this beautiful Rustic Mushroom and Thyme soup. If you are a mushroom lover, this soup is a must! Thyme is such an excellent herb to cook with, I definitely recommend growing it in your garden.

Definitely a hot tip, make sure to break up some crusty bread and add it to your soup! It’s just so delicious!

Let’s Make Some Soup!

The mushrooms give such a meaty flavour and the thyme gives it that earthy rustic taste.

You can definitely make this vegan by substituting the butter for vegan butter or sub 1/4 cup of butter with 2 tbsp of Extra Virgin Olive Oil.

When it comes to adding the salt, I advise adding the bulk of the salting last. This is important if you use salted broth, you don’t want to over-salt your soup.

Baby King Oyster Mushroom really brings this soup to life, this is my favourite mushroom to cook with.
