For the Soup:

  • 3 tablespoons extra-virgin olive oil plus more for drizzling
  • 1 onion sliced
  • 1 large head cauliflower cored and cut into 1 inch pieces
  • 3 garlic cloves smashed
  • 4 cups vegetable or low-sodium chicken broth
  • 2 cup water
  • 2 tablespoons white rice
  • 1 bay leaf
  • Coarse salt and freshly ground pepper
  • 1 tablespoon freshly squeezed lemon juice
  • Croutons and chopped fresh chives for serving

For the Croutons:

  • 2 cups of bite-size bread cubes I like sourdough or a rustic country loaf
  • 1 tablespoon extra-virgin olive oil
  • Coarse salt and freshly ground pepper


  • Preheat oven to 425 degrees.  Toss onion, cauliflower and garlic with olive oil and a sheet pan.  Season with salt and pepper. Roast vegetables until tender and caramelized, stirring occasionally, about 30-35 minutes.
  • Transfer roasted vegetables to a dutch oven or large saucepan.  Add broth, water, rice and bay leaf. Bring to a boil and reduce to a simmer.  Continue to cook until rice is tender, about 20 minutes.
  • While the soup simmers, make the Croutons. Toss bread cubes with olive oil on a rimmed baking sheet. Season with salt and pepper. Bake until toasty golden brown, about 7-9 minutes. Remove from the oven and set aside.
  • Remove bayleaf from the soup.  Puree soup in two batches in a blender until smooth (or use an immersion blender if you have one).  Return soup to pot.
  • Bring soup back to a simmer over low heat.  Add lemon juice and season to taste with salt and pepper.  Serve with Croutons, a drizzle of olive oil and a shower of chopped fresh chives.
