I’ll be honest – when people ask me about making a kosher version of classic bisque, I used to hesitate. The original relies so heavily on shellfish and dairy cream that it seemed impossible to recreate. But after years of experimenting in my kitchen, I’ve developed this mushroom bisque that captures all the silky richness and deep umami flavors you want from the classic version.
The secret lies in building layers of flavor with different types of mushrooms. I use a combination of cremini, shiitake, and porcini mushrooms to create that complex, ocean-like depth that makes bisque so appealing. The dried porcini especially add an earthy intensity that mimics the brininess you’d expect from seafood. Instead of dairy cream, I finish the soup with coconut cream, which provides the same luxurious texture without any kashrut concerns.
Building Umami Without Shellfish
What really makes this version work is the technique. You can’t just throw everything in a pot and expect magic. I start by roasting the fresh mushrooms until they’re deeply caramelized, then build the base with aromatics and a good splash of dry sherry. The coconut cream goes in at the very end – add it too early and it can separate or become grainy. I learned this the hard way after a few batches that looked more like curdled milk than elegant soup.
The Coconut Cream Technique
This bisque works beautifully as a starter for Shabbat dinner or any time you want something that feels special without too much fuss. I like serving it with crusty bread or matzo crackers on the side. It also reheats wonderfully, though you might need to whisk it smooth again since the coconut cream can separate slightly when cooled.

Ingredients
Method
- Preheat oven to 425°F. Soak dried porcini mushrooms in 1 cup hot water for 20 minutes until softened. Reserve the soaking liquid and chop the reconstituted porcini.
- Toss cremini and shiitake mushrooms with 2 tablespoons olive oil and spread on a large baking sheet. Roast for 20-25 minutes until deeply browned and slightly crispy at the edges.
- Heat remaining 1 tablespoon olive oil in a large pot over medium heat. Add shallot and cook for 3 minutes until softened. Add garlic and cook 30 seconds until fragrant.
- Stir in tomato paste and cook for 1 minute until it darkens slightly. Add chopped porcini mushrooms and cook for 2 minutes.
- Pour in sherry and let it bubble for 30 seconds to cook off the alcohol. Add roasted mushrooms, vegetable broth, and strained porcini soaking liquid (discard any gritty sediment at bottom).
- Bring to a boil, then reduce heat and simmer for 15 minutes. Add thyme leaves and simmer 5 more minutes.
- Using an immersion blender, blend until smooth, or blend in batches in a regular blender. Strain through a fine-mesh sieve back into the pot, pressing solids to extract liquid.
- Return to low heat. Open chilled coconut cream can and scoop out the thick cream from the top (save liquid for another use). Whisk coconut cream into the soup until smooth.
- Season with salt and white pepper. Heat gently without boiling for 2-3 minutes. Taste and adjust seasoning.
- Ladle into bowls and garnish with fresh chives. Serve immediately.
