Ingredients
- 2pounds cremini mushrooms, halved, quartered if large
- 2shallots, thinly sliced
- 4thyme sprigs, plus leaves for serving (or 1 teaspoon dried thyme)
- ¼cup extra-virgin olive oil
- 2tablespoons soy sauce
- Salt and black pepper
- 3cups water or chicken broth
- 2teaspoons sherry or white wine vinegar
- ¼cup heavy cream, plus more for serving
Preparation
- Step 1
Heat the oven to 400 degrees. On a sheet pan, toss together the mushrooms, shallots, thyme, oil and soy sauce until well combined. Sprinkle with salt and pepper and spread into an even layer.
- Step 2
Roast until the mushrooms are pooling in liquid, about 15 minutes. Carefully pour the liquid into a small bowl and reserve. Return the sheet pan to the oven and roast, stirring occasionally, until browned, another 25 to 30 minutes.
- Step 3
Discard the thyme sprigs and set aside ½ cup of the roasted mushrooms. If using an immersion blender, transfer the remaining mushrooms to a pot, or transfer to a regular blender. To the sheet pan, add some of the water (about ½ cup but no need to measure) and scrape off the stuck-on browned bits. Pour the mixture into the pot or blender, along with the remaining water, reserved mushroom liquid and vinegar. Blend until smooth.
- Step 4
Warm the soup on the stove over medium-high. Turn off the heat and stir in the cream. Taste; if the flavor is bland, add salt and pepper; repeat until the mushroom flavor is pronounced. Serve topped with a drizzle of cream, the reserved mushrooms and thyme leaves.

Just sauté the mushrooms in butter, with some minced shallots and dried thyme. Much easier, and better than all the oven baking hoopla. Deglaze with a little chicken broth.
There has got to be an easier way of getting mushroom juices. I’m thinking reconstituting some dried mushrooms and using that liquid instead. So much easier than having to scoop all the mushrooms from the baking sheet, pouring off the liquid, then respreading the mushrooms to continue roasting. Clean up would probably be easier, too.
I haven't made this, just saved the link for later. My first thought: This would be a good place for that Parmesan rind in the freezer!
Wow delicious! I added sweet paprika while roasting & used sherry and lime juice instead of sherry vinegar. Combined the roasting w baking a cake so did it mostly at 375
I’ve made this numerous times now and it’s replaced the mushroom soup that I used to swear by. I think that the roasting adds a lot and it really isn’t hard to do at all. My mushrooms are roasting right now! Thank you for an amazing recipe.
Skipped sheet pan roasting, result was spectacular. To below, added 1 carrot and 1 stalk celery diced. 2 tablespoons extra-virgin olive oil, 2 tablespoons unsalted butter 1 medium yellow onion, chopped ½ teaspoon sea salt Freshly ground black pepper 2 containers organic cremini mushrooms 3 garlic cloves, grated ¼ cup sherry, splash of vermouth 3 cups water 2 teaspoons better than bouillon 1 teaspoon aminos 1 teaspoon thyme leave ½ cup heavy cream or creme fraîche, Sautéed onion, carrot celery with thyme in butter and oil. Added mushrooms, kosher salt, then sautéed until dark brown and most all water gone. Added sherry, vermouth, water and bouillon, cooked 15 minutes, added cream and used immersion blender. Pepper and sherry important.
