- 12 large mushrooms about 12 ounces/300 grams (cleaned and thinly sliced)
- 1/2 large onion (thinly sliced)
- 3 tablespoons unsalted butter
- 2 to 3 tablespoons all-purpose flour (we used brown-rice flour to make the soup gluten-free)
- 2 1/2 cups good-quality simmering beef broth
- 3 tablespoons heavy cream
- 2 large egg yolks
- 2 tablespoons good-quality dry sherry
- 1/3 cup crème fraîche
- Dash pepper
- Dash salt
Peel and slice onions as thinly as practical.
In a medium saucepan, sauté onion in 3 tablespoons unsalted butter until translucent. Add 12 ounces/300 grams thinly sliced mushrooms. Sauté 5 minutes. Sprinkle 2 to 3 tablespoons all-purpose flour or brown rice flour over all, cook 1 minute, stirring. Use more flour for a thicker soup. All-purpose flour can be used if you are not allergic to it.
Add 2 1/2 cups hot beef broth (preferably homemade but good-quality canned broth will do), bring to a boil, reduce heat and simmer 1 minute, stirring occasionally.
Add 3 tablespoons heavy cream and reduce heat to lowest setting.
Mix 2 large egg yolks with 2 tablespoons good-quality dry sherry and 1/3 cup crème fraîche. Temper egg yolk mixture with a few ladles of hot soup, whisking constantly. Then transfer the tempered egg-yolk mixture back into the soup. Heat through, whisking constantly, but do not boil. Pepper generously and salt to taste.
This is commonly served with a French baguette.
Raw Egg Warning
Consuming raw and lightly-cooked eggs poses a risk of food-borne illness.
- Mushrooms are very porous, so you want to introduce as little water as possible when cleaning them. Follow these mushroom-cleaning tips.
