# What You'll Need:

→ Mushrooms

01 - 1 pound mixed mushrooms (cremini, shiitake, button), sliced

→ Vegetables

02 - 1 medium onion, finely chopped
03 - 2 cloves garlic, minced
04 - 1 medium carrot, diced
05 - 2 celery stalks, diced

→ Soup Base

06 - 1 tablespoon olive oil
07 - 1 tablespoon unsalted butter
08 - 4 cups vegetable broth
09 - 2 tablespoons dry white wine, optional
10 - 2 teaspoons soy sauce
11 - 1 tablespoon white miso paste
12 - 1 teaspoon smoked paprika
13 - 1/2 teaspoon dried thyme
14 - Salt and freshly ground black pepper to taste

→ Creamy Element

15 - 3/4 cup sour cream or full-fat crème fraîche
16 - 1 tablespoon all-purpose flour

→ Garnish

17 - 2 tablespoons fresh parsley, chopped
18 - Extra sour cream for serving, optional

# How-To Steps:

01 - Heat olive oil and butter in a large pot over medium heat. Add onions, carrots, and celery; sauté for 5 minutes until softened.
02 - Stir in garlic and cook for 30 seconds. Add mushrooms and cook for 7 to 8 minutes, stirring occasionally, until mushrooms are golden and have released their moisture.
03 - Sprinkle flour over the vegetables and stir to coat evenly. Cook for 1 minute to remove raw flour taste.
04 - Deglaze with white wine if using, scraping up any browned bits from the bottom of the pot.
05 - Add vegetable broth, soy sauce, smoked paprika, thyme, salt, and pepper. Bring to a gentle simmer, cover, and cook for 15 minutes.
06 - In a small bowl, whisk miso paste with 2 tablespoons of hot broth until smooth. Stir this mixture back into the soup.
07 - Reduce heat to low. Stir in sour cream until fully combined and the soup is creamy. Do not boil after adding sour cream to prevent curdling.
08 - Taste and adjust seasoning if needed.
09 - Ladle into bowls, garnish with fresh parsley and an extra dollop of sour cream if desired. Serve hot.

# Expert Suggestions:

01 -
  • It tastes like you spent hours tending to it, but honestly takes less time than ordering delivery.
  • The miso-soy combination creates this subtle umami layer that makes people ask what your secret ingredient is.
  • Works beautifully for vegetarians and omnivores alike, so you're never cooking two different meals.
02 -
  • Sour cream curdles if the soup boils after it's added—watch your heat carefully once the cream goes in, and your soup stays silky instead of grainy.
  • Miso paste needs a gentle introduction; whisking it smooth with hot broth first prevents lumpy, unpleasant surprises that ruin the entire texture.
03 -
  • Don't skip the step of coating vegetables in flour—it creates a natural thickener and gives the soup its signature silky mouthfeel instead of watery texture.
  • Taste as you go; miso and soy sauce are salty, so add the final seasoning near the end rather than at the beginning, or you'll overshoot.
