Ingredients

• 200g escargot
• 3 cups mushrooms
• 1 cup onion
• 1 cup heavy cream
• 1 tbsp truffle oil
• 1/2 cup white wine

Instructions

1. Step 1: Dice the 3 cups mushrooms into 1/2-inch cubes and finely chop the 1 cup onion. Heat 2 tbsp olive oil in a large pot over medium-high heat, then add the mushrooms and onion. Cook for 5-7 minutes, stirring occasionally, until the onions are translucent and the mushrooms release their moisture and soften. Tip: Avoid overcrowding the pan—cook in batches if needed to ensure even browning.
2. Step 2: Add the 200g escargot (in their shells) and 1/2 cup white wine to the pot. Reduce the heat to medium-low and simmer for 10 minutes, stirring occasionally, until the escargot is heated through and the wine reduces by half, leaving a syrupy consistency. Tip: If the escargot is pre-cooked, skip any additional cooking time and focus on melding the flavors.
3. Step 3: Pour in the 1 cup heavy cream and stir gently to combine. Bring the mixture to a gentle simmer, then use an immersion blender or transfer to a blender to puree until smooth and velvety, about 2-3 minutes. Tip: For a richer texture, blend until the bisque is completely smooth with no visible chunks.
4. Step 4: Season the bisque with salt and pepper to taste, then return it to low heat. Simmer for 5 minutes, stirring occasionally, until the sauce thickens enough to coat the back of a spoon. Tip: If the bisque becomes too thick, thin it with a splash of broth or additional cream.
5. Step 5: Just before serving, drizzle the 1 tbsp truffle oil evenly over the bisque, swirling gently to distribute the oil. Serve immediately, garnished with fresh parsley if desired. Tip: Truffle oil is best added at the end to preserve its aromatic intensity.
