This Creamy Instant Pot Cauliflower Soup is velvety smooth. Top it with bacon, sour cream and chives for a delicious low-carb dinner!
Ingredients and substitutions
- Olive oil – or another neutral cooking oil like avocado or canola oil.
- Cauliflower – I’d recommend using fresh cauliflower florets, as frozen cauliflower could make the soup too watery.
- Yellow onions – white onions or shallots would be good substitutes here.
- Garlic – freshly minced garlic or jarred garlic can both be used.
- Salt & pepper – to taste.
- Vegetable broth – swap out for chicken broth instead.
- Sour cream – cream cheese, heavy cream or coconut milk can all be used in place of sour cream.
- Grated cheddar cheese – feel free to use any cheese of your choice such as parmesan, Swiss or Monterey Jack.
- Bacon – turkey bacon is a healthier option.
- Chives – leave this off altogether if you’re not a fan of chives.
- Sour cream – use low-fat sour cream to cut down on calories.
- Cheddar – or another cheese of your choice.

Frequently Asked Questions
Using the immersion blender will make your soup nice and thick, in addition to the sour cream and cheese. If you don’t have an immersion blender, you can use a regular blender and puree it in batches. Only fill the blender about half way and cover it with a towel instead of the lid to keep the pressure from building too high. You’ll also want to wait until the soup cools slightly so that the lid doesn’t pop off. Too much hot liquid can explode if you try to blend it too quickly.
You can add whatever toppings you want to this delicious soup! In addition to the suggestions in the recipe card, you can also try garnishing your soup with leeks, capers, mushrooms, jalapenos or even roasted chickpeas.

Storing and reheating
This cauliflower soup will last in the fridge for 4-5 days. When you are ready to eat the leftovers, just pop them in the microwave for a few minutes until hot and then add your garnishes. You can reheat it in the stovetop and bring it to a simmer over medium-low heat.
Can you freeze cauliflower soup?
You can freeze this soup with a few small adjustments. Make the Instant Pot cauliflower soup as directed, but don’t add the sour cream or cheese. Allow it to cool completely, then freeze it in Ziploc bags or glass containers for up to 6 months.
When you’re ready to enjoy your soup, reheat it in a pot on the stovetop from frozen then add in your sour cream and cheese. The sour cream and cheese won’t defrost well, so you only want to add them in after reheating.
