Roasted Cauliflower, Garlic, and Leek Soup

Chef V

"I absolutely love roasted cauliflower, so I came up with this soup one cold day. You don't even need to add cream to this soup to be completely satisfied with the thick creamy texture the cauliflower adds. Roasting the cauliflower and garlic brings the flavor of it to a whole other level. Double the recipe to assure leftovers, as it tastes almost better the next day for lunch! I serve this soup for lunch or dinner with a good cheesy bread. Enjoy!"

  • Prep

  • Cook

  • Ready In

  1. Preheat oven to 400 degrees F (200 degrees C). Grease a baking sheet.
  2. Put cauliflower florets into a large bowl. Drizzle olive oil over the cauliflower; season with salt and pepper. Add garlic to the cauliflower and spread onto a baking sheet.
  3. Roast in preheated oven for 15 minutes, turn the florets and garlic, and continue roasting until golden brown, about 10 minutes more.
  4. Melt butter in a large pot over medium heat. Cook and stir celery and leek in hot butter until softened, about 5 minutes. Stir flour into the celery mixture; cook and stir until flour is heated, 2 to 3 minutes more.
  5. Stream chicken broth into the pot while continually stirring to incorporate. Add cauliflower, garlic, and marjoram to the broth mixture; bring to a simmer and cook until the flavors develop together, about 10 minutes.
  6. Blend soup with an immersion blender to your desired consistency; season again with salt.


  • Tip
  • Aluminum foil helps keep food moist, ensures it cooks evenly, keeps leftovers fresh, and makes clean-up easy.

Delicious recipe without any changes. If you want to indulge a bit, add 1/4 cup half and half for a creamy taste. Otherwise skip the extra calories:-)

SO good. Had no leeks so I used a chopped onion I already had. Used extra garlic (because you can never have too much IMO), added chopped up carrots, and Cavender's Greek seasoning, and used thy...

This turned out great! I used minced garlic instead of fresh, coconut oil (warmed in my little oven to make it liquid) instead of olive oil on the cauliflower, and gluten free baking flour. I ...

Loved this soup! We just did a quick run-through with the immersion blender, to leave some chunks of roasted cauliflower.

Made a double batch of this to stick in the freezer. Have a new baby on the way and my son loves soup. It's a great way to hide some really good veggies for the hubby too. Looking forward to pul...

This is the best Cauliflower soup I have ever made. I used Bob's Red Mill gluten free all purpose baking mix instead of flour, and added two extra garlic cloves, otherwise made as noted. This wi...
