The Instant Pot is perfect for making the most delicious cauliflower cheese soup ever.

Instant Pot Cauliflower Cheese Soup

The flavors of this soup are amazing and will have the family going back for seconds. The soup is smooth, cheesy, and will easily feed a crowd. I highly recommend it if you want a homemade meal that will keep the family happy.

A single batch of this recipe should make enough to feed roughly four to six people. I highly recommend that you make some side dishes so that everyone finishes with a full stomach.

You can make this cauliflower cheese soup in a slow cooker. The results are roughly the same, but you can leave it cooking for hours rather than minutes. You can use the slow-cook function on the Instant Pot.

Any leftover soup is excellent the next day for lunch or dinner. The soup should last in the refrigerator for at least three days or three months in the freezer.

Soup Serving Ideas

One of my favorite side dishes to go with this soup is some lovely fresh bread. There is nothing better than dipping some bread into the soup and soaking up all the lovely flavors. It is the perfect combination, and I highly recommend it.

If you have a bit of spare time in the kitchen, I recommend making some cornbread to go with the soup. Our cornbread recipe is gluten-free and loaded with lots of flavors, thanks to the ham, cheese, and tomatoes.

There are plenty of different garnishes that will work great with this soup. For example, I love to sprinkle the soup with crispy bits of bacon and some chopped chives. Croutons are another excellent garnish that will work great with this soup.

For the ultimate cheesy dinner, you can make a grilled cheese sandwich to go with the soup. I absolutely love dipping the sandwich into the cheesy soup. It is a slightly unhealthy but incredibly delicious way to eat this soup.

Tweaking the Cauliflower Cheese Soup

There are a few tweaks that you can make to this soup so that it is more to your liking. If you have any ideas that you want to share, be sure to leave us a comment at the bottom of this page.

Adding blue cheese into the soup is a great way to add even more flavor. I recommend adding roughly 150g (5.3 oz) of blue cheese for the best balance of flavors. Keep in mind, some blue cheeses are stronger than others.

To achieve a creamier soup, you can double or triple the amount of cream. You will need to be careful as too much cream may make the soup very runny.

Adding a couple of potatoes into the soup is a great way to thicken the soup without flour. I recommend cutting the potatoes small as you want them to cook at the same rate as the cauliflower. Alternatively, you can use a mixture of cornstarch and water to thicken the soup.

Recipe Tips

  • I use chicken stock in this recipe, but other types will work fine. For example, vegetable stock is a great replacement.
  • Fresh or frozen cauliflower will work fine for this recipe. I prefer fresh, but frozen will work just as well.
  • Slowly season the soup as it is extremely easy to overseason and make it too salty. I recommend tasting after every addition of salt and pepper.
  • This recipe will work great in most types of pressure cooker.

Note: I use a 5.7L (6 Quart) Instant Pot for all of the pressure cooker recipes I have on this website. If you have a smaller or larger pressure cooker, you may need to adjust the quantities in this recipe.
