Instructions
Preparation Steps
Melt butter in a medium saucepan over medium heat. Add mushrooms and onion and cook, stirring occasionally, until the mushrooms release their liquid and the pan looks mostly dry with light browning, about 6 to 8 minutes.
Stir in garlic and cook until fragrant, about 0.5 minute.
Sprinkle flour over the mixture. Stir constantly to form a paste and cook off the raw flour taste, about 2 minutes.
Gradually whisk in the chicken broth until smooth and thick. Slowly whisk in the milk and then the cream, keeping the mixture lump-free.
Add thyme, soy sauce, salt, and pepper. Simmer gently, stirring often, until very thick and reduced to a condensed, scoopable consistency, about 3 to 5 minutes. You should have about 2.0 cups.
Taste and adjust seasoning. If too thick, whisk in a splash of milk; if too thin, simmer a bit longer.
Use immediately or cool to room temperature. For soup, whisk with an equal amount of water or broth and heat until steaming.
Notes
Storage: Refrigerate in an airtight container up to 4 days. Freeze up to 2 months; thaw overnight and whisk to re-emulsify. Gluten-free: use a gluten-free all-purpose flour blend. Vegetarian: use vegetable broth. For deeper color and umami, add 0.25 teaspoon mushroom powder or a few dashes of Worcestershire sauce.
