Ingredients

Scale

Main Ingredients

  • 1 large head cauliflower cut into florets
  • 3 tablespoons olive oil divided
  • 1 medium yellow onion chopped
  • 5 cloves garlic minced
  • 15 ounce can cannellini beans drained and rinsed
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon dried rosemary
  • 4 cups vegetable broth
  • 1 tablespoon lemon juice
  • salt and pepper to taste

Garnish

  • Croutons, for garnish, or a few roasted cauliflower florets


Instructions

  1. Roast cauliflower: Preheat the oven to 425 degrees F. Toss the cauliflower florets with 2 tablespoons of olive oil and sprinkle with salt. Arrange in a single layer on a large baking sheet and roast for 35 minutes, flipping halfway, until caramelized and golden.
  2. Sauté aromatics: When the cauliflower has about 10 minutes remaining, heat the remaining 1 tablespoon olive oil in a large pot over medium heat. Add the chopped onion and sauté for 4 minutes until translucent, then add the minced garlic and cook for 1 more minute.
  3. Add beans and herbs: Stir in the cannellini beans, dried thyme, dried rosemary, vegetable broth, and the roasted cauliflower (reserve a few florets for garnish). Bring the mixture to a boil, then lower heat and simmer for 10 minutes.
  4. Blend the soup: Carefully transfer the soup in batches to a blender and blend until smooth and creamy. For a chunkier texture, use an immersion blender to blend partially. Return the soup to the pot.
  5. Finish and season: Stir in the lemon juice and season with salt and pepper to taste. Warm through if needed.
  6. Serve: Ladle the soup into bowls and garnish with croutons or reserved roasted cauliflower florets. Serve with crusty bread for dipping and enjoy.

Notes

  • For a richer, creamier soup, add 1/2 cup vegan cream, full-fat coconut milk, or blend in 1/2 cup raw cashews along with the soup.
  • Store leftover soup in an airtight container in the refrigerator for 3-4 days or freeze for longer storage.
  • Be careful not to overfill the blender to avoid spills when blending hot soup.
  • Use an immersion blender for a quicker, mess-free blending option with more texture retained.
