Because it’s so flavorful and luxe, a little goes a long way – so a 1 cup serving would be just right.

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!
Notice Title
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.
