Ingredients
- 1 lb mushrooms, chopped
- 1 onion, chopped
- 2 cloves garlic, minced
- 4 cups vegetable broth
- 1 cup heavy cream
- 2 tablespoons truffle oil
- Salt and pepper to taste
Instructions
- Begin by preparing all your ingredients. Chop the mushrooms and onion, and mince the garlic. This will help streamline the cooking process.
- In a large pot or Dutch oven, heat a tablespoon of olive oil over medium heat. Once hot, add the chopped onions and sauté for about 5 minutes, or until they become translucent and fragrant.
- Add the minced garlic to the pot and sauté for an additional 1-2 minutes, stirring frequently to prevent burning.
- Next, add the chopped mushrooms to the pot. Cook them for about 10 minutes, stirring occasionally, until they release their moisture and become tender.
- Pour in the vegetable broth, bringing the mixture to a gentle boil. Once boiling, reduce the heat to low and let it simmer for about 10 minutes. This allows the flavors to meld together.
- After simmering, use an immersion blender to puree the soup until smooth. If you do not have an immersion blender, carefully transfer the soup in batches to a countertop blender and blend until smooth. Return the pureed soup to the pot.
- Stir in the heavy cream and truffle oil, mixing well to combine. Allow the bisque to heat through on low heat for about 5 minutes, but do not let it boil.
- Season the bisque with salt and pepper to taste. Adjust the seasoning as needed, keeping in mind that the truffle oil will add a rich flavor.
- Once heated through, remove the bisque from the heat. Serve hot, garnished with a drizzle of truffle oil or a sprinkle of chopped fresh herbs if desired.
Tips
- Choose fresh, high-quality mushrooms for the most intense flavor. A mix of button and cremini mushrooms works wonderfully.
- Don't rush the sautéing process—allowing onions and mushrooms to caramelize slowly develops deeper, more complex flavors.
- Use a high-quality truffle oil to ensure an authentic, rich taste. A little goes a long way, so add it sparingly.
- For the smoothest texture, use an immersion blender or carefully blend in batches if using a countertop blender.
- Keep the heat low when adding cream to prevent curdling and maintain a silky-smooth consistency.
- Taste and adjust seasoning gradually—the truffle oil already adds significant flavor complexity.
