Mary Berry’s Cream of Mushroom Soup is a velvety, savoury soup made with fresh mushrooms, onions, and garlic simmered in stock and finished with cream. The result is a perfectly balanced dish — creamy, hearty, and full of natural mushroom flavour.
Butter – 40g
Olive oil – 1 tbsp
Onion – 1 large, finely chopped
Garlic – 2 cloves, crushed
Chestnut mushrooms – 400g, sliced
Plain flour – 1 tbsp
Vegetable or chicken stock – 800ml
Double cream – 150ml
Fresh thyme – 1 tsp (optional)
Salt and black pepper – to taste
Fresh parsley – chopped, for garnish
(Optional: Add a few drops of truffle oil for a gourmet touch.)
Melt the butter with olive oil in a large saucepan over medium heat. Add the onion and cook gently for 5 minutes until soft and translucent. Add the garlic and cook for 1 minute more.
Add the sliced mushrooms and cook for about 8–10 minutes, stirring occasionally, until they release their moisture and start to turn golden brown.
Stir in the flour and cook for 1 minute to remove the raw taste. Gradually pour in the stock, stirring constantly to prevent lumps. Add the thyme and bring the mixture to a gentle simmer for 10 minutes.
Remove from heat and use a hand blender or transfer to a stand blender to puree until smooth. If you prefer a chunkier texture, blend only half the soup and mix it back in.
Return the soup to low heat. Stir in the cream, season with salt and pepper, and warm through (do not boil).
Ladle into bowls, garnish with fresh parsley or a swirl of cream, and serve with crusty bread or buttered toast.
