  • 2 tbsp. olive oil divided
  • 2 garlic cloves minced
  • 1 large leek chopped, white and green parts separated
  • 1 cup dry white wine
  • 5 cups cauliflower florets about 1 lb.
  • 4 cups vegetable broth
  • 2 cups unflavored soy or almond milk
  • 1/2 tsp. black pepper
  • 1/4 tsp. salt or to taste
  • 1 lb. white button mushrooms wiped clean, stems removed, and sliced
  1. Coat the bottom of a large saucepan or Dutch oven with 1 tablespoon of olive oil. Place over medium heat. Add white parts of leeks and garlic. Sautée until leeks are softened, about 5 minutes.
  2. Add wine and raise heat to medium-high. Bring to a simmer, Allow to simmer, stirring occasionally, until reduced by half, about 5 minutes.
  3. Add broth and cauliflower. Bring back to a simmer and allow to cook until cauliflower is tender, about 10 minutes.
  4. While cauliflower simmers, coat a large skillet with remaining 1 tablespoon of olive oil and place over medium heat. Add mushrooms in as even a layer as you can get them and cook for 5, minutes, until lightly browned on bottoms. Gently flip and cook another 5 minutes on opposite sides. Remove from heat and transfer to a plate.
  5. Working in batches if needed, transfer cauliflower mixture to blender or food processor and blend until completely smooth. This may take a few minutes. Return to pot.
  6. Add milk, salt and pepper to cauliflower mixture. Place over medium-high heat and cook just until heated throughout. Stir in mushrooms and green parts of leeks.
