2 tablespoons butter
1 small onion, finely chopped
2 cloves garlic, minced
1 ½ pounds fresh mushrooms, sliced
4 cups chicken broth
½ cup sherry
1 ½ teaspoons dried thyme
1 teaspoon Worcestershire sauce
1 teaspoon salt, or more to taste
½ teaspoon ground black pepper, or more to taste
4 tablespoons all-purpose flour
1 cup heavy cream
Turn on a multi-functional pressure cooker (such as Instant Pot®) and select Saute function.
Heat the butter until melted. Sauté the onion for 2 to 3 minutes. Add the garlic and cook it for 1 to 2 minutes. Add the mushrooms and sauté them 2 to 3 minutes.
Stir the chicken broth, sherry, thyme, Worcestershire sauce, salt, and pepper into the pot. Close and lock the lid. Pressure cook on Manual for 5 minutes. Allow 10 to 15 minutes for the pressure to build.
Release the pressure using the natural-release method ~about 10 minutes. Release the remaining pressure carefully using the quick-release method. Unlock and remove the lid.
Select the Sauté function again to bring the soup to a light simmer.
Whisk the flour into the heavy cream. Slowly add the cream mixture to the simmering soup, whisking constantly until it’s thickened, 2 to 3 minutes.
Turn pressure cooker off. Season the soup with additional salt and pepper, if desired.
Use vegetable broth instead of chicken broth to make it vegetarian.
