This is a very special Mushroom Soup. There are flavours in here you are going to love. In fact I think you are going to be really surprised when you see how it’s made.
Mushrooms are like a vitamin pill, I love them and I love soup. I can eat soup anytime. What about you?.
The thing about mushrooms is they go very well with butter and really cheesy things too and sometimes it’s a little rich for me. So I came up with this way to make a thick creamy soup without the cream or butter so I can eat more.
I know. Am I supposed to be saying stuff like that?. Probably not.
So let’s face it sometimes Mushroom Soup can go a bit wrong. It can be too thin and watery, how embarrassing ( and hunger inducing) . It can be like I mentioned before way too creamy and buttery and I sure don’t want to add flour to my soup because that would just dull those mushroom flavours. I just want those mushroom flavours to be sweet and present.
I was kind of thinking too, it needs just that little hint of lemon but juice just seemed too aggressive. Yeah I know I wanted my mushrooms in a gentle flavour bubble that would bring out their little characters but not wack them and tell them to sit down.
Preserved lemon. It came to me in a voice just like that.
Perfect. A darkly gently lemon character that just fits the bill.
Next I have added a bag of raw cashews because when they are cooked up they make the nicest creamiest base. Their flavour, the one that I love so much when they are roasted and salted is not at all the same when they are raw and cooked. They take on other flavours (like mushrooms) and become one with them.
I hope cashews are not something you feel you shouldn’t be eating because cashews are one of Gods little surprises for savoury and sweet cooking.
Not only do cashews have a lower fat content than most other nuts, but approximately 82% of their fat is unsaturated fatty acids, plus about 66% of this unsaturated fatty acid content are heart-healthy monounsaturated fats, similar to those found in olive oil. They have a hugely impressive antioxidant effect on the body too.
Now I am not one for banging on about health foods because all foods in the old moderation. But. You must try my Mushroom Soup because……..
Mushrooms are vitamin pills + cashews are antioxidants = good times and good eats.
Now once this creamy wonderful thick Mushroom Soup is ready you can eat it all up. Luckily, it also keeps well. It will probably get thicker as it sits and cools so the best thing to do is add a bit more stock when you reheat it.
Now just because I love you I have also tried using it as a sauce too. It’s great with pasta. This ricotta and spinach ravioli found it a lovely bed to rest on. i used lashings of fruity olive oil and grated Parmesan cheese all over the top.
Hey, give the soup a try and tell me how you went?
PPSS You can make this vegan by using vegetable stock. Here’s the video.
Like this idea?. Try my Cauliflower, Quinoa and Spinach Soup too.

Mushroom Soup, preserved lemon and cashews
Ingredients
- 500 gm mushrooms sliced button or field
- 60 ml olive oil
- 150 gm onion diced (or a couple of small ones brown or white)
- 3 cloves garlic depending on their size and strength
- 1 1/2 tablespoons Thyme chopped de-stemmed
- 250 gm cashews raw unsalted
- 50 gm preserved lemon chopped. You can use the insides just not the seeds
- 1 litre chicken stock
- 1 teaspoon sea salt
- 2 mushrooms field or Portabello mushrooms sliced
- 40 ml olive oil 2 tablespoons
Instructions
- Heat the pot over medium heat and add the 60 ml of olive oil. Add the onion and garlic and stir to mix and soften.
- Add the thyme and the preserved lemon, stir well then add the 500 gm sliced mushrooms. Stir till softened ( about 2 minutes).
- Add the cashews and the stock and simmer on medium to low for approximately 20 minutes or until the cashews are soft.
- Season with salt and puree till silky smooth.
- I like to garnish with sliced mushrooms. Make them by heating a skillet ( frypan). Add the extra olive oil ( and some butter if you like) and toss the mushrooms, adding a little salt till they are cooked through. Set aside till needed

Here’s my Mushroom Soup Sauce. Looks delicious don’t you think?.
Does this soup freeze well?
Can’t see why not Meimei
I am totally a soup person too, although I must admit, my favourites are usually the broth-based soups (like Italian Wedding Soup, Pho, Chicken Noodle…) but a creamed mushroom soup is one that I simply adore! I love pairing it with cashews, so creamy. I made a chicken tikka masala by Jamie Oliver and he also used cashews as a thickener (sometimes I use almonds in his recipe). Have you thought of chestnuts? The subtle sweetness is a perfect pairing to the earthy mushroom flavours. The preserved lemon would add just the perfect brightness (I love using lemon instead of salt to coax out the flavours).
Hi Eva. yep soup is the best. I love mushrooms with chestnuts too. cashews just have the most amazing creamy texture though. I can’t resist them
I too can have soup all the time! Your mushroom soup must be very flavourful with preserved lemon and cashews.
Thanks Angie. Is it bad that I ate it all?
Love the idea of this soup. Hope you bring it over to Food on Friday: June under the pot luck category. Cheers
Great recipe, Tania. Looks delicious!
Hi John. thanks.
What a brilliant idea to use cashews in place of cream / butter. I know what you mean about mushroom soup often being too thin or too creamy – excellent solution and delicious sounding flavours, too!
Thanks Kari. I thought it was good I hope you try it
