Why I Love This Recipe

  • Flavorful—The process of roasting the cauliflower and garlic brings such a delicious flavor to this soup!
  • Creamy—We love the ultra smooth texture and flavor of this roasted cauliflower and garlic soup. It’s perfect on a cold day served with crusty bread or in a bread bowl.
  • Veggie First—There’s a whole head of cauliflower is in this soup, and I appreciate comfort food that’s meatless. (Here are more vegetarian meal ideas).

How to Make Roasted Cauliflower Soup

Prep Cauliflower and Garlic: Remove core and leaves then cut into bite-size florets. Place on a large baking sheet and toss with 1 to 2 tablespoons olive oil, salt, and pepper.

Remove the papery leaves from the bulb of garlic, leaving the skin and leaving it as a whole bunch. Cut ¼ inch from the top of the cloves then drizzle olive oil on the exposed garlic cloves so it drips down the inside. Place whole bulb inside a piece of aluminum foil then seal closed. Place on baking sheet next to cauliflower.
