Ingredients

Find the full ingredient list, with measurements, in the recipe card below.

  • olive oil – This is for sauteing the veggies.
  • onion, celery, and garlic – These veggies create a flavorful base for the soup.
  • potatoes – We recommend Yukon gold potatoes for their buttery and mildly sweet flavor, which adds richness.
  • cauliflower florets – When cooked and blended, cauliflower becomes incredibly smooth and creamy, making it ideal for this recipe.
  • vegetable broth – We use our homemade vegetable broth in this recipe but feel free to use your favorite kind. You could also substitute chicken broth but it will no longer be a vegan recipe.
  • milk – We use full-fat coconut milk, but you can substitute any milk or cream.
  • salt and pepper – Essential for seasoning your soup.

Equipment

  • large saucepan – We use a 3-quart stainless steel soup pot.
  • sharp knife and cutting board – For prepping the vegetables.
  • wooden spoon – Our favorite kitchen tool for stirring soups and stews.
  • immersion blender – We use a handheld immersion blender for blending this soup. It is so easy to do it right in the pot. You could also do it in a regular blender in batches.

Instructions

Scroll down to the recipe card at the bottom for the FULL recipe details.

Step 1

First, heat the oil in a large soup pot. Then, sweat down the onions and celery. Once they are soft, add the garlic and stir for another minute.

Step 2

Next, add in the chopped potatoes. We leave the skins on because the soup will be blended and the skins add fiber, texture, and lots of earthy flavor.

Step 3

Then add the cauliflower and broth and bring the mixture to a boil.

Step 4

Next, reduce the heat and simmer for 20 to 25 minutes until the potatoes and cauliflower are tender.

Step 5

Then, remove the pot from the heat and, using an immersion blender, blend until smooth and there are no lumps or chunks left.

Step 6

Finally, stir in the coconut milk and add salt and pepper to taste. Ladle into a bowl and serve warm.

Expert tips

Taste your soup before serving and adjust the seasoning as needed. Cauliflower can absorb quite a bit of salt, so be cautious not to over-salt initially.

A dash of lemon juice or vinegar can also brighten up the flavors if it feels a bit flat.

Recipe variations

  • Sauté mushrooms along with the onions for added earthy depth.
  • Kick up the heat with the addition of chili flakes, hot sauce, or diced jalapeños for a spicy version.
  • Instead of sauteing the garlic, roast the whole garlic cloves before blending them into the soup. This lends a smoky flavor that tastes incredible.
  • Swap regular potatoes for sweet potatoes to add a hint of sweetness and a vibrant orange color to the soup. Pair this with curry spices for a fusion of flavors.

Serving suggestions

  • Garnish with chopped fresh herbs like parsley, chives, cilantro, or fresh thyme.
  • For a loaded baked potato soup sprinkle on shredded cheddar cheese, crumbled bacon, and chopped chives or green onions. If you want to keep this recipe totally vegan use Daiya cheese shreds and vegan coconut bacon.
  • Pair your cauliflower potato soup with a light salad for a balanced meal. Try a simple green salad with an easy Balsamic Vinaigrette Dressing.

FAQS

What can I do if my soup turns out too thick?

You can thin it out by adding more broth, water, or milk until you reach the desired consistency.

Can I make cauliflower potato soup in a slow cooker or Instant Pot?

Yes, you can adapt this recipe for slow cooker or Instant Pot cooking. Simply follow the appropriate guidelines for your appliance, adjusting cooking times accordingly.

Storage tips

  • Store any leftovers in the fridge in an airtight container for up to 3 days. Reheat it gently on the stove or in the microwave when you’re ready to serve.
  • You can freeze cauliflower potato soup for longer storage. However, be aware that the texture may change slightly upon thawing, as dairy-free alternatives can separate when frozen.

    Love cauliflower soup and adding potatoes just makes it even more smooth and creamy. I love soups even in the summer, this one is a keeper!

  5. 5 stars
    Total winner! I had a soup nearly identical to this on Saturday and immediately can home to try and find a recipe. This is perfection. I had never made soup before (I know, I know) but this was simple and it’s so delicious.

    1. Thanks so much Megan!! I’m also a big fan of simple/delicious things. 🙂 I appreciate the time for commenting and the rating! Hope this soup keeps you warm all winter.

    1. Hey Madeline! Yes, this can be frozen but I would leave out the coconut milk and add that in when you reheat the soup. I hope you enjoy!

  6. Gorgeous (is it weird to call food gorgeous? Haha)! I love both cauliflower and potato soup, but I’ve never combined them. I think they would really complement each other though, with the potatoes adding some nice creaminess!

    1. Food is most definitely gorgeous. 😉 The combination was heaven. Potatoes just make any pureed soup a little bit better.

  7. This soup looks so yummy Sharon, I was actually searching for coconut soup recipes last night 😉 Glad to hear everything is back up and running fine! I know the feeling, too scary!

    1. Thanks Karen! Tis the season for all things soup. 😉 It’s not super coconutty, so I would double the milk in this if you want to really taste the flavour.
