Cauliflower and Roasted Garlic Soup

 [This post has been updated from the Oven Love archives.]

This soup is exceptional.


It’s so good that every fall for the last four years, we’ve remembered it and had to have it again. You know how rare it is for me to make a recipe twice.. so I think this is going to be a Herr family favorite.

There is nothing more satisfying than a creamy soup on a cool night, am I right? The roasted garlic in this thing is no joke- so, so good- do not skip that step! If it weren’t for the garlic breath, I would eat a head of roasted garlic every. single. day. (TMI?)

The soup is filling as a meal all it’s own, but makes a great starter for a holiday spread as well. And I just love the roasted cauliflower florets on top with their cheesy, herbaceous flavor. Great presentation for company, but also a perfect supper to share with your family.
