Ingredients

Scale

Mushrooms and Vegetables

  • 200 g cremini mushrooms, sliced
  • 150 g oyster mushrooms, sliced
  • 1 small yellow onion (120 g), finely diced
  • 3 garlic cloves, minced

Cooking Fats and Flavorings

  • 3 tbsp (43 g) unsalted butter
  • 1 tablespoon olive oil
  • ¾ teaspoon cracked black pepper
  • 1 teaspoon balsamic vinegar
  • 2 teaspoons soy sauce (regular or light)
  • ¼ teaspoon white sugar
  • 6 thyme sprigs (leaves separated from sprigs for cooking)
  • 1 small bay leaf

Thickening and Liquids

  • 4 tablespoons all-purpose flour
  • 3 ½ cups chicken stock (or 3 ½ cups water with 2 stock cubes)
  • Salt to taste (about ½ teaspoon suggested)
  • 1 cup (250 ml) heavy cream

Instructions

  1. Sauté Onions: Melt the unsalted butter in a Dutch oven over medium heat, then add the olive oil and finely diced onions. Cook the onions until they are soft and lightly browned, which brings out their natural sweetness and builds flavor for the bisque.
  2. Cook Mushrooms: Add the cremini mushrooms to the pot and increase the heat to medium-high. Cook for 2 minutes before adding the oyster mushrooms. Continue cooking for about 10-12 minutes until the mushrooms are deeply caramelized, developing a rich, concentrated flavor.
  3. Add Garlic and Seasonings: Reduce the heat to medium-low, then stir in the minced garlic. Cook for 2 to 3 minutes until the garlic becomes fragrant and is no longer raw. Next, season the mixture with cracked black pepper, balsamic vinegar, soy sauce, white sugar, bay leaf, and thyme leaves (removed from sprigs). Stir everything together to evenly distribute the flavors.
  4. Incorporate Flour: Sprinkle the flour over the mushroom mixture and cook for about 3 minutes, stirring constantly. This step cooks off the raw flour taste and helps thicken the bisque.
  5. Add Stock and Simmer: Gradually pour in the chicken stock (or water with stock cubes), stirring continuously to prevent lumps. Bring the soup to a slow simmer and cook, stirring occasionally, until the broth thickens slightly. Once thickened, turn off the heat.
  6. Blend the Soup: Using an immersion hand blender, blend the mushroom mixture directly in the pot until smooth. Alternatively, carefully transfer the soup in small batches to a regular blender and puree until smooth, exercising caution with hot liquids.
  7. Add Cream and Simmer: Return the blended soup to medium heat. Stir in the heavy cream, letting the bisque simmer gently on medium-low heat to allow it to thicken slightly and for the flavors to meld together.
  8. Season to Taste and Serve: Taste the bisque and adjust salt as needed—typically about ½ teaspoon depending on your stock. Serve hot in bowls, garnished with a swirl of cream, fresh thyme sprigs, and some caramelized mushrooms for added texture and presentation.

Notes

  • For a vegetarian version, use vegetable stock instead of chicken stock.
  • Be careful while blending hot liquids; blend in batches and vent the blender lid slightly to avoid steam buildup.
  • Caramelizing the mushrooms well is key to developing the deep umami flavor of this bisque.
  • You can add a splash of white wine before adding the stock for extra depth if desired.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently to avoid curdling the cream.
