Instructions
 

Prep the Cauliflower & Sauté Aromatics

  • Split the cauliflower in half; chop one half into florets and slice the other into thick cauliflower steaks. In a pot, sauté garlic and king trumpet mushrooms until golden, then add cabbage and the cauliflower florets.

Build the Soup Base

  • Stir in miso, spices, herbs, flour, and nutritional yeast to coat the vegetables. Slowly pour in plant milk and vegetable broth, stirring until slightly thickened.

Simmer & Blend

  • Simmer the soup until the cauliflower is very soft, then blend until silky smooth. Taste and adjust seasoning with more miso, herbs, or nutritional yeast.

Sear & Broil the Cauliflower Steaks

  • Sear the cauliflower steaks in a hot pan until deeply golden on both sides. Transfer to a tray, season, top with vegan cheese and herbs, and broil until melted and lightly browned.

Serve & Finish

  • Ladle the creamy vegan mushroom cauliflower soup into bowls and top each one with a cheesy cauliflower steak. Garnish with fresh herbs, pepper, or a drizzle of chili oil.
