Making the classic dish with an easier, shortened approach and less cooking time.
Ingredients
1lb (450 g)white or brown mushrooms, sliced
5tablespoonsbutter, divided
1/2white onion, minced
3tablespoonsall-purpose flour
4cupschicken stock
1teaspoondried parsley
1bay leaf
Pinch of thyme
1/4teaspoonsalt
4egg yolks(Optional) (*Footnote 1 & 2)
1/4cupheavy cream
parsley or croutons, for garnish (Optional)
Instructions
Heat 3 tablespoons butter in a 3.5-quart dutch oven or heavy duty pot over medium heat. Add onion and turn to medium-low heat. Cook and stir onion until tender and translucent, about 8 minutes. Do not brown the onion.
Add flour and continue stirring over medium-low heat for 3 minutes, until flour and onion are well combined.
Add chicken stock, about one cup at a time. Stir constantly until it forms a silky paste and starts simmering.
Add the parsley, bay leaf, and thyme. Simmer over medium-low heat, partially covered, for 15 to 20 minutes, until the soup reaches the desired thickness.
While simmering the broth, cook the mushrooms. Melt the remaining 2 tablespoons of butter in a large skillet until the butter starts to bubble. Add mushroom slices and season with salt. Stir a few times to mix well. Cook, stirring occasionally, until the mushrooms are browned, about 5 minutes. Add the mushrooms into the soup.
Combine the egg yolks (if using) and heavy cream in a small bowl and beat until mixed well. Slowly add the cream-yolk mixture into the broth. Adjust the seasoning with salt and more cream if necessary. Heat over lowest heat for another 5 minutes. Do not bring the soup to a simmer.
Garnish with chopped parsley or croutons. Serve hot.
Notes
The original recipe uses egg yolks to create a thicker soup. When I want a lighter soup, I use just heavy cream and skip the egg yolks. It produces a satisfying soup that is almost as creamy.
The nutrition facts are calculated without any egg yolks or toppings.
