Porcini Chestnut Soup with White Truffle Oil
This is a sumptuous, umami laden soup perfect in the fall with fresh Chestnuts, or with vacuum packed ones through the winter. The recipe is also designed for the Thermomix machine.
Ingredients
- 10 g dried Porcini (or local dried Alberta Mushrooms from Mo-Na's Foods)
- 1/2 cup boiling water for hydrating dried Porcini
- 30 g extra virgin olive oil (my favourite local oil remains the President's Choice Brand from Superstore)
- 1 onion , chopped roughly
- 2 plump garlic cloves
- 500 g whole Cremini mushrooms , chopped
- 200 g vacuum packed chestnuts , chopped (available locally at The Italian Centre)
- 700 g cooking liquid (homemade chicken stock plus Porcini rehydrating liquid)
- 100 g heavy cream
- salt and pepper to taste
- white truffle oil for garnish (available locally at The Italian Centre)
Instructions
Instructions with the Thermomix:
- Scale 10g of Porcini mushrooms, soak them in 1/2 cup of boiling water for 10 minutes, and retain liquid
- Scale in the olive oil and add the onion and garlic; chop for 5 seconds at speed 7
- Clean sides of bowl with the spatula; sauté for 2 minutes at 100°C on speed 5
- Scale in chopped Cremini and sauté for 2 minutes at 100°C on R-4
- Scale in chestnuts, reconstituted minced Porcini, strained Porcini water and chicken stock to total 700g liquid; cook for 10 minutes on Varoma at speed R-4
- Purée for one minute slowly from 1-10, until smooth
- Add cream, adjust seasoning and serve with a drizzle of truffle oil (2-3 drops per boil, as it is very strong)
Instructions without the Thermomix:
- Weigh 10g of Porcini mushrooms, soak them in 1/2 cup of boiling water for 10 minutes, and retain liquid
- Measure 2 tablespoons of olive oil into a stock pan and heat; add the chopped onion and garlic
- Sauté for 2 minutes, stirring constantly; add the chopped Cremini and sauté for 2 minutes more minutes on high heat
- Add chopped chestnuts, reconstituted minced Porcini, strained Porcini water and enough chicken stock to total 700g liquid; bring to a low boil and cook for 10 minutes
- Test for doneness, then carefully move mixture to a blender: secure lid with a cloth over the top to avoid heat explosions or burns
- Purée for one minute slowly, or until velvety smooth
- Add cream, adjust seasoning and serve with a drizzle of truffle oil (2-3 drops per boil, as it is very strong)
OH MY WORD VALERIE !!! Your soup is OUTSTANDING. I am salivating all over the keyboard here. This is fantastic. BRAVO. I want some! You are so smart to have brought back Porcini mushrooms from Firenze. I am so very envious. Great photos. Thank you so much for this post!
Oh my goodness Valerie, thanks for sharing this with the contest, or I might not have found it. I adore mushroom soup, even though it isn’t very pretty. Your recipe sounds awesome!
This is a truly outstanding looking soup. I can just smell and taste it as you describe it. I wish I had some truffle oil, but its not in our budget at the moment, so I am just going to have to come up with something else 🙂 Thanks for sharing Valerie.
Hey, Michelle!
I do not understand why truffle oil is so expensive when it is just an artificial essence. Talk about making the most of the market! I got a nice sized bottle – or artisan infused oil – the real deal, in Italy this fall. Still have to do a comparative taste test. It was 10 Euro, which was cheap considering it was 3 times the size of the one I bought the year before that was fake and 20 Euro. The bottles at the Italian Centre Shop are very reasonably priced considering their size – too big, really. Enough oil in them for a life time. A tiny bottle would last a year or more and comfortably cost ten Canadian if anyone would do that for us! The soup is grand without the finishing oil – but, it is definitely the cream on the strawberry shortcake… essential to the overall impact.

Would love to make this could you use chestnut puree instead of chopped chestnuts thanks
Yasmin,
I would check out your neighbourhood Italian grocer for the vacuum packed chestnuts. The puree is markedly different.
