Notes

Chef’s Note: Sauté the mushrooms in two uncrowded batches until well-browned and nearly dry, then deglaze with a splash of dry sherry or white wine to pull up the fond—this small step intensifies the soup’s earthiness. Just before serving, whisk in a teaspoon of white miso for an extra layer of umami without additional salt.

Frequently Asked Questions

Can I make this mushroom soup dairy-free or vegan?
Yes—simply use olive oil (or vegan butter) instead of butter, choose vegetable broth, and replace the heavy cream with full-fat coconut milk, cashew cream, or another plant-based alternative. Skip any Parmesan garnish or use a vegan “Parmesan,” and the soup becomes completely dairy-free and vegan without altering the core method.
Can I freeze this creamy mushroom soup, and what’s the best way to reheat it?
Yes—let the soup cool completely, then ladle it into airtight containers (or freezer bags laid flat), leaving about 1 inch of headspace, and freeze for up to 3 months. Thaw overnight in the refrigerator, then warm it gently over medium-low heat, whisking occasionally; if the dairy has separated, a quick blitz with an immersion blender or a splash of broth/cream will restore its silky texture.
How can I adapt this mushroom soup to be gluten-free?
Replace the 2 Tbsp of all-purpose flour with either 2 Tbsp of a cup-for-cup gluten-free flour blend or 1 Tbsp of cornstarch whisked into 2 Tbsp cold broth, then add it after the mushrooms brown. Verify that your broth and optional white wine are labeled gluten-free, and the rest of the recipe remains unchanged.
