Luscious vegetarian soup with mushrooms, stroganoff flavors, miso umami, and creamy sour cream in 45 minutes.

# What You Need:

→ Mushrooms

01 - 1 lb 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 Make:

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 7–8 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 Tips:

01 -
  • It's a weeknight wonder that tastes like you spent hours on it, but comes together in 45 minutes flat.
  • The miso hides in the background like a secret, making the mushroom flavor sing without announcing itself.
  • One pot means one cleanup, and somehow that matters more than it should.
02 -
  • Never boil the soup after adding sour cream or it will separate and look curdled; keep your heat low and your patience high once the cream goes in.
  • Whisking the miso paste with hot broth before adding it prevents lumps; I learned this the hard way when I got impatient and stirred it straight in.
03 -
  • Make it in advance and reheat it gently on the stovetop; the flavors actually deepen overnight in the fridge.
  • For a vegan version, swap the butter for vegan butter and use cashew cream instead of sour cream; it works beautifully and nobody will notice the difference.
