Cream of Mushroom Soup

This is the best cream of mushroom soup I have ever had. We made it at the restaurant for the daily soup special and this was also the “secret” ingredient in our green bean casserole. I personally like both textures (and look) of mushrooms in the soup. I slice half the mushrooms and chop the other half. But feel free to use the mushrooms however you would like.

Why it works: Mushroom and cream are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 4,500 recipes mention both. Both carry 2-heptanol, which smells bitter, floral. The science ↓

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Strip the thyme leaves from the 3 sprigs only if you prefer, otherwise keep the sprigs whole. Slice the mushrooms into even pieces and chop the onion.

  2. Heat 1 tablespoon of the olive oil in a large heavy pot over medium-high heat. Add the mushrooms in batches and cook, stirring, until browned and their liquid has evaporated, about 8 minutes. Transfer to a bowl.

  3. Add the remaining 1 tablespoon olive oil and the butter to the pot over medium heat. Add the onion and cook, stirring, until soft and translucent, about 5 minutes.

  4. Sprinkle the flour over the onions and stir constantly for 1 minute to cook off its raw taste.

  5. Gradually whisk in the vegetable stock until smooth. Add the thyme sprigs and the cooked mushrooms, then bring to a simmer.

  6. Reduce the heat to medium-low and simmer uncovered, stirring occasionally, until the soup has thickened slightly and the vegetables are tender, about 15 minutes.

  7. Remove and discard the thyme sprigs. Season with the sea salt or kosher salt and the black pepper, adjusting to taste.

  8. Stir in the half-and-half and heavy cream and heat gently for 3 to 4 minutes without letting it boil. Stir in the parsley just before serving.

Flavor stand-ins for the onion

How well each one fits the dish's main ingredients (mushroom, shiitake, olive, thyme, butter, flour, pepper):

  2. Potatobetter flavor fit
  3. Capsicumbetter flavor fit
  4. Onionthe original

Fit is the average pairing score against mushroom, shiitake, olive, thyme, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
