This incredibly easy Instant Pot Keto Cheesy Cauliflower Soup was well received even by the sworn cauliflower haters! If you already love cauliflower, then you’re never going to want to stop eating this rich, yet mellow Keto cauliflower soup.
I ate it for lunch three days straight and was still sad when it was gone. True story.
Rich and satisfying on its own, this Instant Pot Keto Cauliflower Soup makes a fantastic first course when you’re entertaining. Because it’s so flavorful and luxe, a little goes a long way – so a 1 cup serving would be just right. It reheats beautifully, so you can make it a day or two before your event and then just heat right before serving to your guests.
To make this very white keto cauliflower soup more attractive and add a little texture, I fried up some thin slices of garlic to garnish it with in these pictures. It not only made it look prettier, but the fried garlic was really tasty in the soup as well.
A nice touch especially when you are serving this Instant Pot keto cauliflower soup to guests – just be careful not to overcook the garlic, or it will be very bitter and not at all appetizing.
I used horseradish cheddar for the cheese in this Instant Pot Keto Cauliflower Soup, and while the horseradish flavor wasn’t overly forward I loved the slight tang that it delivered. That being said, you could absolutely use another type of cheese to flavor your version of this keto cauliflower soup!
I recommend a strongly flavored cheese for best results – a good quality sharp cheddar, smoked cheddar or smoked gouda, or even a nice Asiago would be lovely.
This Cheesy Instant Pot Keto Cauliflower Soup recipe is vegetarian as written – but you could absolutely punch up the flavor even more by replacing the water with chicken stock (the final soup color will be more golden) and throwing some crumbled cooked bacon on top to garnish.
