It’s December and although we still don’t have snow here on the North Coast of British Columbia, I still feel that nip in the air. Something that really comforts me this time of year is soup. Last night I made this Roasted Cauliflower and Cheddar Soup and it was delicious. So out came the leftovers and the camera.

This recipe started out with cauliflower. I had a head of cauliflower staring at me in the fridge and I knew my husband was getting tired of Roasted Cauliflower with Parmesan and Balsamic (my go-to side dish). It was time to switch it up, but I wasn’t too sure on what I should make. I wanted soup and when I opened my fridge I saw half an onion, chicken broth and a jar of minced garlic, that’s when I remembered my favorite broccoli soup (Roasted Broccoli and Cheddar Soup from Closet Cooking) and thought a pureed cauliflower soup was in order.

A sheet pan with raw cauliflower sprinkled with garlic powder, salt, and pepper.

I was a little hesitant about making this as I wasn’t too sure if the cheese would taste good with the cauliflower. Then I realized that was silly because cheese usually makes everything taste better and if I’m able to make a few “baked” cauliflower and cheese recipes that Cauliflower and Cheese Soup would be fine.

Although the recipe for cauliflower and cheddar soup first appeared on the blog in December 2013, I took out my camera recently and reshot the recipe. Since the colors are neutral I wanted to make the images interesting and added parsley. I even tried to be fancy and add a swirl of olive oil on top, this step is totally optional by the way. I simply wanted to explain why you see oil on top of the soup in the new photos! ☺️

Calories 243kcal


  • 1 large head of cauliflower chopped
  • 2 tbsps olive oil
  • Sea salt and pepper
  • 1 tsp  garlic powder
  • 1/2 onion chopped
  • 3 tbsp minced garlic
  • 5 cups chicken broth
  • 2 - 2 1/2 cups double cheddar cheese


  • First, you need to roast the cauliflower. It's easy. Lightly toss your cauliflower in 1 tbsp olive oil, salt, pepper, and garlic powder. Line a baking sheet with foil and roast at 425 degrees until the florets begin to brown. About 30 minutes.
  • Over medium heat up your remaining olive oil and saute your onion until soft in a stock pot.
  • Add cauliflower and stir around for a minute.
  • Add chicken broth. Bring to a boil and then reduce the heat down to a simmer and cover. I left it there to simmer for 30-35 minutes.
  • Use an immersion blender or transfer your soup to a food processor/blender and puree.
  • Bring your soup back to the pot and add the cheddar.
  • Stir to melt and serve, I serve with pepper.

  1. Mmmmm that sounds yummy! Cauliflower is one of our favourites around here!

  2. I LOVE cauliflower and cheese soup but I’ve never made my own. This sounds like a very simple method and looks absolutely delicious. Just one thing I wanted to clarify, I’m guessing you cut the head of cauliflower into florets first even thought you didn’t state that?

    I don’t have a favourite soup recipe yet as I’ve not made my own. I keep meaning too though!

  3. This is exactly how my mom makes her homemade soup! So delicious!! Yum yum!

  4. This is very similar to my recipe for Cauliflower Soup. It’s one of my absolute favourites! And so easy to make. It’s a great weeknight meal with some fresh bread.

  5. I love comfort food once the cold weather comes, and soup definitely falls into that category! This looks like a tasty recipe… all that delicious cheesy goodness *might* even be able to hide the fact that the soup is cauliflower (for my picky, non-vegetable-loving kids). I’m definitely going to give this one a try – thanks!

  8. I’ve never seen this recipe before but it looks so good and so do the ingredients

  9. I don’t use cauliflower in my recipes mostly because I don’t know how to cook it. I will have to try this one soon. Thanks for sharing at #HomeMattersParty

  10. 5 stars
    This is a very easy recipe geared for the home cooks that have never attempted this and you did a great job laying this out. However, in your directions and ingredients list you forgot to mention that you slice up the large head of cauliflower before roasting. Oops♥

  11. You don’t list the minced garlic in the instructions. Where do you add the garlic
