Ingredients

• 1 ounce dried porcini mushrooms (optional, but highly recommended)
• 1 cup hot water (for soaking porcini)
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 2 pounds fresh mushrooms (cremini, shiitake, or a mix of button and wild mushrooms recommended; button mushrooms alone are acceptable), cleaned and sliced
• 1 large yellow onion, chopped
• 3 cloves garlic, minced
• 1 teaspoon fresh thyme leaves, chopped (or ½ teaspoon dried thyme)
• ¼ cup all-purpose flour (see substitutions for GF option)
• 4 cups vegetable broth or chicken broth
• 1 tablespoon soy sauce or Worcestershire sauce (for umami boost)
• 1 cup whole milk
• ½ cup heavy cream
• 1 tablespoon fresh lemon juice
• 1 teaspoon salt, or to taste
• ½ teaspoon black pepper, or to taste
• ¼ cup fresh parsley, chopped (optional, for garnish)

Directions

1. Optional Porcini Prep : If using dried porcini, place them in a small heatproof bowl and cover with 1 cup of hot water. Let them soak for 15-20 minutes until softened. Carefully remove the porcini with a slotted spoon, reserving the soaking liquid. Finely chop the rehydrated porcini. Strain the reserved soaking liquid through a fine-mesh sieve or coffee filter to remove any grit; set aside.
2. Brown the Fresh Mushrooms : In a large Dutch oven or heavy-bottomed pot, melt the butter and olive oil over medium-high heat. Add the sliced fresh mushrooms in an even layer (you may need to do this in two batches to avoid crowding the pan). Cook, stirring occasionally, until all the mushroom moisture has evaporated and the mushrooms are deeply browned and caramelized, about 8-10 minutes per batch. This browning is key for flavor! Transfer the browned mushrooms to a bowl and set aside, leaving any rendered fat in the pot.
3. Sauté Aromatics : Reduce the heat to medium. Add the chopped onion to the pot and cook, stirring, until softened and translucent, about 5-7 minutes. Stir in the minced garlic and chopped thyme; cook for another minute until fragrant.
4. Make a Roux : Sprinkle the flour over the onion mixture. Cook, stirring constantly, for 1 minute to cook out the raw flour taste.
5. Whisk in Liquids : Gradually whisk in the broth, scraping up any browned bits from the bottom of the pot. If using, slowly whisk in the strained porcini soaking liquid. Bring the mixture to a gentle simmer.
6. Simmer & Thicken : Continue to simmer, stirring occasionally, for 5-7 minutes, until the soup has slightly thickened.
7. Add Dairy : Reduce the heat to low. Stir in the whole milk and heavy cream. Add the soy sauce or Worcestershire sauce and the chopped rehydrated porcini (if using). Return the browned fresh mushrooms to the pot. Simmer gently for another 5-10 minutes, ensuring the soup does not come to a hard boil after adding the dairy.
8. Blend for Body : For a truly creamy texture, carefully transfer 1-2 cups of the soup to a blender (be cautious with hot liquids, venting the lid) or use an immersion blender directly in the pot. Blend until smooth, then return the blended portion to the pot and stir to combine. This adds body without making the whole soup a puree.
9. Finish & Season : Remove the soup from the heat. Stir in the fresh lemon juice. Season with salt and black pepper to taste.
10. Serve : Ladle the hot soup into bowls. Garnish with fresh parsley, if desired, and serve immediately.
11. What “Done” Looks Like
12. Your creamy mushroom soup should have a luscious, spoon-coating consistency (it should "nappe" the back of a spoon). The flavor should be deeply savory and mushroom-forward, with a subtle brightness from the lemon juice that prevents it from being too heavy.
