Mushroom Soup with Truffle

This mushroom soup is surprisingly simple to prepare, yet so delicious and elegant. The star of the dish is fresh truffle. I used black winter truffle, because that is what’s available at the moment. Although truffle isn’t cheap — this was 1 euro per gram — a small truffle of only 14 grams sufficed for 4 servings. You could use any type of fresh mushrooms including simple button mushrooms, but with wild mushrooms it will be even better. Another vital ingredient is dried mushrooms. I used dried porcini mushrooms, but a mix of various dried mushrooms may even be better. Making the mushroom stock from scratch is worth the effort — you don’t want to use store-bought bouillon for this!

Ingredients

For 4 servings as an appetizer

250 grams (.55 lb) fresh mushrooms, I used mixed wild mushrooms

1 fresh truffle, about 15 grams (1/2 oz)

40 grams (1.5 oz) dried mushrooms, I used porcini

200 grams (1 cup) minced onion

200 grams (1 cup) minced celery

200 grams (1 cup) minced leek

200 grams (1 cup) minced carrot

2 garlic cloves

fresh thyme

black peppercorns

salt and freshly ground black pepper

1 Tbsp olive oil

Instructions

Put the dried mushrooms in a bowl and add 1 litre (4 cups) of hot water. Allow the mushrooms to soak while you continue the preparation of the stock.

Heat a tablespoon of olive oil in a frying pan. Add minced carrot, celery, onion, and leek, as well as 4 sprigs of fresh thyme and 2 whole garlic cloves.

Clean and trim the fresh mushrooms and add all the trimmings to the pan.

Stir over medium-high heat for about 10 minutes, or until the vegetables start to turn golden. This step is important for developing the flavor of the stock.

Now add the dried mushrooms with the soaking water…

…and some black peppercorns.

Bring to a boil.

Cover, reduce the heat to a simmer, and allow to simmer for 1 hour.

Strain the stock through a fine sieve, pressing down on the solids to get out as much liquid as possible. The aim is to get maximum flavor, not a clear stock.

Pour the mushroom stock into a pot and bring to a boil. Season with salt. When the stock boils, add the fresh wild mushrooms, and cook them in the stock for about 10 minutes.

Take some nice looking mushrooms out of the stock and reserve for garnish. For 4 servings I selected 12 pieces (3 per serving).

Puree the soup with an immersion blender. You could also use a regular blender.

When the soup is smooth, bring it back to a boil. Adjust the seasoning to taste with salt and freshly ground black pepper.

Serve the soup on preheated plates. Garnish with fresh thyme leaves and the reserved mushrooms, and shave the truffle…

…such that each serving has some nice slivers of truffle. Serve at once.

Wine pairing

This is great with an elegant but earthy red wine, such as an aged Barbaresco, Roero, Ghemme, or other aged Nebbiolo, or a Red Burgundy.

Flashback

Mole poblano is an amazing sauce from Mexico that includes lots of chiles as well as chocolate.

  1. An interesting recipe that is quite different from mine (beef stock). I bet it is very flavorful. Too bad we cannot get fresh truffles here (Texas). Someday, maybe. The ones we can get do not have an impressive flavor.

    1. It will be more ‘mushroomy’ with stock from dried mushrooms than with beef stock. The problem with truffles is that they deteriorate pretty quickly, so even here they are not as good as in Italy even though Italy is only a 2 hour flight away.

  2. Unbelievably Australia has become one of the biggest truffle producing countries in the world. I seem to live in a suitable climatic zine as there are half-a-dozen truffle farms within a couple of hours drive. *smile* That does not mean that I have as yet visited or that they are not rather expensive . . . indeed more so than yours ! Love the way you have made your soup – probably using the meatier types of Asian mushrooms shall try it soonest even without the truffle . . . all things being fair snd equal may well splurge on the black gold as their winter season comes on . . . of red burgundy there is no shortage . . .

    1. Off topic – Am having the time of my life watching the Dutch speed skaters in Beijing ! Nought bar a lot orange on the track . . . actually decades ago the handsome Dutch guys raised my interest in the sport (hmm !) and were the precursor to my passion for world-wide road racing ! And am SO glad your Ireen Wust at her age again managed the 1500m gold !

    2. I had never heard about Australian truffle before. With ‘farm’ I suppose you mean a place where truffles are found, because as far as I know they can’t be grown. Without the truffle this is still nice, but not as special of course.
