Cauliflower is a versatile veggie that can be dressed up in many ways. Roast it, mash it, make cauliflower rice, and so more!

Here we’ll be simmering the cauliflower until tender and pureeing it until creamy smooth (or to your desired texture), creating a perfectly luscious soup.

Why We Love This Recipe!

  • No fuss recipe! This vegan cream of cauliflower soup requires no roasting and is a one-pot recipe for a quick and delicious soup recipe!
  • Healthy! It’s creamy and delicious without any dairy cream making it 100% dairy free. The soup will thicken when pureeing the cauliflower and adding the vegan cream.

Ingredient Notes

In this simple cauliflower soup recipe, onion, garlic, thyme, and cauliflower are cooked until tender, then pureed into a creamy and delicious soup that’s a healthy whole food, plant-based lunch, or dinner.

Here is everything you will need:

  • Cauliflower – use a large 2 1/2 to 3-pound head, or use pre-cut cauliflower for convenience.
  • Onion – any color will do.
  • Garlic – fresh garlic is best, but can be substituted with garlic powder.
  • Thyme – use fresh or dried.
  • Vegan butter – adds a wonderful richness to the final soup. My favorite is Miyokos. You substitute with olive oil or water if preferred.
  • Vegetable broth – we recommend low-sodium or vegetable concentrate, such as Better Than Bouillon Vegetable Paste, that makes it easy to control the amount used.
  • Vegan cream – use store-bought or homemade vegan cream (sub your almond milk, cashew milk, or favorite plant milk)
  • Lemon – adds a light zestiness.
  • Salt + pepper

How To Make Vegan Cauliflower Soup

  • Prep: Start by prepping the onion and garlic. Cut the cauliflower into florets.

  • Add remaining ingredients: Add the cauliflower, thyme, salt, pepper, and water.

  • Simmer: Bring the chunky soup to a boil, cover, reduce heat and simmer for 20 minutes.
  • Add cream: Stir in the vegan cream or plant milk and lemon juice.
  • Puree: Let the soup rest for 10 minutes to cool. Using an immersion blender or cup blender, puree the soup until desired consistency. Reheat on the stove if needed to warm back up before serving.

And now you’re ready to enjoy!

Top Tips

  • Reserve cauliflower pieces: Reserve a few pieces of cauliflower and toast in a toaster oven with a little oil to help it caramelize along the edges. It makes for a great soup topper with a lovely toasted flavor.
  • Cutting cauliflower: When chopping the cauliflower, don’t worry about making the pieces small. You can always break it up as it cooks down and softens.
  • Recommended equipment: I used my immersion blender (affiliate link) to puree the soup. A standing blender is great too, but may take two batches to puree.
  • Toppings: Add a little heat with a pinch of red pepper flakes or crushed mustard seeds.

How To Store, Freeze + Reheat

  • Refrigerator: Leftovers will keep for 5 – 6 days in the refrigerator, stored in a covered container.
  • Freezer: Vegan cauliflower soup is freezer friendly and freezes well for up to 2 – 3 months. To freeze, let cool completely and store in multi-use, freezer safe containers (affiliate link), leaving 1/2 inch head space for expansion. You can also freeze larger portions in large freezer ziplock bags. Let thaw before reheating.
  • Reheat: Simply re-warm on the stovetop over low heat until warmed through. Alternatively, reheat in the microwave using 30 – 60 second intervals, stirring after each, until warm.
  • Meal Prep: It makes a great meal prep for the week with homemade Artisan Bread or Vegan Naan on the side for soaking up the juices.

Serving Suggestions

This cauliflower soup is great alone for a light meal but can be made even heartier with a little something extra on the side. Here are a few of my favorite serving suggestions:

  1. This was amazing! The flavor was mellow but fine tuned making it a great soup to accompany a number of main dishes. In my case, vegan crab cakes with spicy lemon aioli sauce and lemon sautéed asparagus. Will make it again and again. I replaced the vegan cream with coconut milk only because I was running low on oatmilk and needed that for my coffee. Haha! I also browned the cauliflower prior to adding it to the pot. This, of course, shrinks them quite a bit- which was perfect as I like a thinner soup. Will certainly be checking into your other recipes. Thank you so much.

  2. This soup is delicious! I subbed Herbs de Provence for the thyme, and went with about 4 cups of broth and water; I made your cashew cream and it’s better than I imagined it would be. This soup tastes a lot like the potato soup my mom made, but with cauliflower, I would assume the nutritional benefits are greater. Thank you!

  3. Good soup but the directions do not say what to use the 1/4 cup of vegan butter for. I assumed it was for sauteing the onion and garlic (which in the directions says to use oil or water), so that is what I did.

    1. Julie | The Simple Veganista says:

      I’ve fixed it, Nancy! Thanks for pointing that out, not sure how we missed that one. :)

  4. Yum! Good recipe! Reminds me of the cauliflower soup I had in Ecuador—we’d sprinkle popcorn over the top of the soup bowl as a treat.

  5. This soup was delicious! I used a homemade veggie broth and that vegan cream is divine. Thanks for the terrific recipe!

  6. This was really good!!

  7. I’m wondering if I can add everything to the instant pot and then blend it after the fact…

    1. Julie | The Simple Veganista says:

      Great question, Natalie! Yes, you can absolutely do that. Will be so easy! Enjoy :)

  8. I have an overabundance of frozen cauliflower rice – I don’t know how that happened!! I’m going to use that instead of fresh cauliflower and a cup of Nutpods for the vegan cream. I’m slowly making my way through your soup recipes and everything has been delicious so far!

  9. I love these simple soups and always appreciate the substitution options from TSV.

    I added a bit of rosemary and coriander to the last batch I took out of the freezer and it made it even better. Thank you!

  10. I tried this recipe. It’s amazing. Used it as sauce for pasta alfredo too thank you!

      Oh that’s a great idea – alfredo for pasta!
