A deeply savory, velvety mushroom bisque built on layers of browned mushrooms, aromatic garlic, gentle herbs, and a touch of sherry. A slow simmer develops richness without heaviness, while soy sauce adds depth and umami. Finished with a swirl of crema, it is earthy, comforting, and elegant—perfect for cool evenings or a refined first course.

To Serve
Directions
Sauté the Aromatics and Mushrooms
In a large saucepan or Dutch oven, melt 2 tbsp butter over medium heat. Add the onion and cook 3–4 minutes until softened. Add mushrooms, salt, and pepper. Cook 10–12 minutes, stirring occasionally, until mushrooms release their liquid and begin to brown. Add garlic and cook 1 minute until fragrant.
Deglaze and Simmer
Add sherry and cook 1 minute, scraping up browned bits. Add 3 cups chicken stock, bay leaf, thyme, soy sauce, and optional porcini mushrooms with their strained soaking liquid. Bring to a gentle simmer, cover, and cook 20 minutes to deepen flavor. Remove bay leaf.
Prepare the Roux Base
In a separate saucepan, melt remaining 2 tbsp butter over medium heat. Whisk in flour and cook 2–3 minutes until lightly golden. Slowly whisk in remaining 1 cup chicken stock, then the half and half, cooking until smooth and slightly thickened.
Combine and Purée
Add the mushroom mixture to the roux base. Purée with an immersion blender until smooth, or blend in batches. For a rustic texture, reserve 1 cup mushrooms before blending and stir them in afterward.
Season and Finish
Return soup to low heat. Add sambal oelek if using. Taste and adjust with salt, pepper, sherry, or soy sauce as desired. Simmer 5 minutes to meld flavors.
Serve
Ladle into bowls and finish with a light drizzle of crema. Garnish with sautéed mushrooms, thyme, or chives.
Notes
Preparation
- Browning mushrooms before adding liquid deepens flavor significantly.
- Use a mix of mushrooms for depth—cremini, shiitake, oyster, or button.
- Porcini add a noticeable boost of umami; highly recommended.
- Blend smooth for a classic bisque or leave some mushroom pieces for texture.
- Simmering longer (rather than adding more flour) develops richness naturally.
Serving Suggestions
- Drizzle with crema to balance richness and add gentle tang.
- For enhanced crema, whisk in a splash of sherry, white pepper, thyme oil, or a pinch of soy sauce.
- Serve with crusty bread, garlic croutons, or a simple green salad.
- Add a few sautéed mushrooms or a swirl of mushroom oil for presentation.
Variations
- Vegetarian: Use vegetable stock and a splash of soy sauce for depth.
- Rustic Mushroom Soup: Blend only half the soup and keep the rest chunky.
- Truffle Version: Finish with a few drops of truffle oil.
Make-Ahead & Storage
- Refrigerate up to 3 days; flavors deepen overnight.
- Freeze without dairy addition; add half and half after reheating for best texture.
- Rewarm gently over low heat to avoid separation.
