I absolutely LOVE creamy soups. There’s something particularly comforting and flavourful about them. Like my Instant Pot potato leek soup and butternut squash soup, this soup is perfectly smooth, simple and delicious.

How to make Instant Pot cauliflower soup

(This is a summary with step by step photos, full recipe measurements and instructions are in the recipe card below.)

To prepare, gather your ingredients and roughly chop your onion and break the cauliflower into large florets.

Don’t worry about uniform size pieces since everything will be pureed later anyhow. This alone saves you time on prep work!

Add all 5 ingredients to your Instant Pot and give it a stir. (photo 1)

Close the lid, seal the valve and set to high pressure for 4 minutes. Once the timer is complete, quick release the steam valve and open the lid once safe to do so. (photo 2)

NOTE: For stove top directions, see the recipe card below.

Using an immersion blender, puree your soup until it is smooth and creamy. (photos 3-5)

NOTE: If you don’t have an immersion blender, you may carefully transfer (in batches) to a stand blender and puree. Use extreme caution and don’t overfill your blender.

NOTE: If you enjoy creamy soups like this one, I highly recommend a stick/immersion blender! Not only is it faster because you can process the entire batch in one shot, but it also saves the mess and hassle of dirtying and washing your blender.

Serve garnished with chili flakes, black pepper, basil, or a drizzle of hot sauce, (I like Sriracha).

You may also add toppings such as air fried chickpeas, vegan parmesan cheese, or croutons.

For a more classic style cauliflower soup, while still keeping it vegan, top your bowl with some vegan bacon bits, or shredded cheddar style cheese.

How long does it keep?

Leftovers can be refrigerated for up to 5  days, just reheat and serve.

You may also freeze in an airtight container (once cooled) for up to 3 months.

Remember to leave a little room for expansion.

Expert tips, tricks & variations

• Add more seasoning if desired. This soup is designed to be simple, using minimal ingredients, while still delivering great flavour. If preferred, add some cumin, coriander, celery seed, or smoked paprika to amp up the flavours.
• For cheesiness, add ¼ cup of nutritional yeast to the pot, before cooking.
• For added protein, add a can of white beans to your pot before cooking. Or add a block of silken or soft tofu once cooked and puree with your soup.
• If you want a richer, thicker soup, add 2 roughly chopped potatoes to the pot before cooking and puree together with the cauliflower once cooked. Or, if you’re not avoiding nuts, add ½ cup of cashews to the mix.
• Bulk it up and make this simple soup suitable for a main dish by adding a scoop of cooked brown rice, barley or quinoa to each bowl before serving.
• Use an immersion blender to puree. An immersion or stick blender makes pureeing soups a lot easier. No need to transfer hot liquids, making it simpler and less messy. Plus, no added risk of burns or mishaps.
