Cauliflower soup

This roasted cauliflower soup recipe is rich and creamy…but it doesn’t call for any cream. Instead, the blended cauliflower creates its luscious texture—no dairy required!

I’ve had this cauliflower soup recipe in my cold weather rotation for years now. Even though all the ingredients are plant-based, it’s just as comforting as any soup made with heavy cream, milk, or cheese. On a chilly winter night, it absolutely hits the spot! It’s also super simple to make, so there’s lots to love here.

Cauliflower soup recipe ingredients

Cauliflower Soup Ingredients

You only need 10 basic ingredients to make this creamy cauliflower soup:

  • A head of cauliflower, of course! It gives the soup a silky texture without any nuts or dairy.
  • Garlic and shallots – You’ll roast them along with the cauliflower. Once they’re tender and caramelized, they add rich, nutty flavor to this cauliflower soup.
  • Fresh thyme – For fresh, earthy flavor.
  • White miso paste – It adds savory, umami flavor that tastes fantastic with the roasted cauliflower, shallots, and garlic.
  • Dijon mustard – For tang.
  • Extra-virgin olive oil – For richness.
  • Vegetable broth – Make homemade vegetable broth, or use store-bought.
  • Fresh lemon juice – It makes the soup nice and bright.
  • And sea salt and fresh black pepper – To make all the flavors pop!

How to Make Cauliflower Soup

I like to think of this cauliflower soup recipe in three easy steps: roast, simmer, and blend.

First, roast the veggies. Break the cauliflower into florets and chop up the cores. Peel and quarter the shallots. Wrap them in a piece of foil with the unpeeled garlic cloves, a drizzle of olive oil, and salt and pepper.

Recipe Tip

Don’t have shallots? Replace them with half a yellow onion, chopped. Use the onions just like you would the shallot—add them to the foil along with the garlic!

Spread the chopped cauliflower florets and core in an even layer on a parchment-lined baking sheet, and toss them with oil, salt, and pepper. Add the foil packet to the sheet, and roast until all the vegetables are tender and the cauliflower is browned.

Next, simmer. Bring the vegetable broth to a simmer in a large pot over medium heat. Peel the garlic cloves, and stir them into the pot along with the cauliflower, shallots, and thyme. Reduce the heat to low and simmer for 15 minutes.

Finally, blend the soup. Allow it to cool slightly. Then, transfer it from the soup pot to a blender. Add the miso paste, mustard, olive oil, and lemon juice.

Feel free to use an immersion blender for this step if you prefer!

What to Serve with Cauliflower Soup

When you’re ready to eat, garnish your bowl with micro greens, fresh parsley, and/or freshly cracked black pepper. This cauliflower soup would also be fantastic with homemade croutons on top for crunch!

Enjoy the creamy soup with focaccia, crusty bread, or a grilled cheese sandwich on the side for dipping.

It also pairs nicely with a side salad. Make a simple green salad by tossing mixed greens with Italian dressing, honey mustard dressing, or lemon vinaigrette, or try one of these 25 Winter Salad Recipes!

Enjoy!

Got leftover soup? Store it in an airtight container in the refrigerator for up to 4 days. It’ll thicken in the fridge, so you might need to stir in a little water when you reheat it in the microwave or on the stove.

This cauliflower soup freezes well too. Allow it to cool to room temperature. Then, transfer it to airtight jars or containers, leaving an inch for the soup to expand at the top. Freeze for up to 3 months!

Allow frozen soup to thaw overnight in the fridge before reheating.

This roasted cauliflower soup is velvety and rich, even though it's made without cream or cheese. The blended cauliflower creates the soup's amazing creamy texture - no dairy necessary!

Ingredients

Instructions

  • Preheat the oven to 400°F and line a large baking sheet with parchment paper.
  • Chop the cauliflower including the core pieces. Transfer to the baking sheet, drizzle with olive oil, and sprinkle with salt and pepper. Toss to coat and spread evenly on the baking sheet. Wrap the shallot and garlic cloves, along with a drizzle of olive oil and a pinch of salt, in a piece of aluminum foil and place it on the baking sheet with the cauliflower. Roast for 30 to 35 minutes, or until the cauliflower is browned around the edges.
  • In a large pot or Dutch oven, bring the vegetable broth to a simmer over medium heat. Add the roasted cauliflower, shallots, peeled garlic, and thyme and simmer, covered, for 15 minutes. Let cool slightly and transfer to a blender. Add the olive oil, miso paste, mustard, and lemon juice. Blend until smooth. Season to taste with ¼ to ½ teaspoon more salt and more lemon juice. Garnish with microgreens, if desired, and serve.

    I am no where close to being a vegetarian but I had a head of cauliflower that I needed to use AND I had miso. Used chicken broth. I am about ready to eat the entire the pot of soup! Delicious.

    This has quickly become a favorite in my house. Love how easy and delicious it is! We pair it with a nice wheat ciabatta and your Caesar salad recipe (with homemade dressing). The perfect combo!

    Could you please clarify the 3 tbsp of olive oil in the recipe? Is this total amount to be added at the end, or is it part of the drizzle you pour over the cauliflower and shallots before roasting? Thank you! 🙂

    • Jeanine Donofrio
      02.15.2022

      Hi Susan, the 3 tablespoons goes into the blender in step 3. Thank you for pointing this out because it should be listed with “more for drizzling” for the roasted cauliflower in step 2.

    I don’t have a good blender, can I use an immersion blender for the last step of this recipe and leave all ingredients in the pot?

      You can!

    Delicious and easy to make. I feel the recipe should say when to peel the garlic, since it’s listed as “unpeeled” in the ingredients list but “peeled” when it’s added to the blender.

    Delicious and easy to prepare. I was confused about the garlic because the ingredients lists says “unpeeled,” but the instructions say to add peeled garlic to the blender. I cooked it unpeeled and peeled it before putting it in the blender, but I feel the peeling step should be added for clarity.

    This was fantastic. I love the rich creamy texture without butter or cream. Thank you for the delicious vegan recipe. I didn’t have miso so I subbed soy sauce and it was yummy!

    I’ve never used miso paste. Rather than buy a whole container for just a 1/2 tablespoon, can I skip it or substitute?

      I add a third of a bottle of coconut aminos instead and it turns out delicious!
