Equipment

  • 1 Food processor or blender

Ingredients

  • 1 large head of cauliflower, cut into florets
  • 2 large shallots, halved lengthwise
  • 2 garlic cloves, smashed
  • 3 Tablespoons extra-virgin olive oil
  • 4 cups low-sodium vegetable broth, warmed
  • 2 Tablespoons unsalted butter, melted
  • ½ teaspoon dried rosemary
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 Tablespoon fresh lemon juice
  • fresh rosemary, chopped (for garnish)

Instructions

  • Preheat oven to 425 degrees F.
  • In a large mixing bowl, toss cauliflower florets, shallots, and garlic with olive oil until evenly coated in oil.
  • Transfer to a rimmed baking sheet and bake until the cauliflower is tender and lightly browned, around 30 minutes, tossing halfway.
  • Reserve ½ cup of the roasted cauliflower florets for garnish. Working in batches, combine the cauliflower/shallots/garlic mixture, warm broth, melted butter, dried rosemary, salt, and pepper in a blender or food processor.
  • Process until smooth, about 45 seconds. Transfer the mixture to a large saucepan. Bring the soup to a simmer over medium-low heat, stirring occasionally. Remove from heat and stir in lemon juice.
  • Divide among 4 bowls and garnish with the reserved cauliflower florets and fresh rosemary.

Notes

Storage: Place soup in an airtight container and store in the refrigerator for up to 4 days.
