Creamy Roasted Cauliflower Rosemary Soup Recipe

If you have been around here for a while you know that our family is a fan of roasted vegetable soups (see our dreamy perfect Mediterranean style Roasted Tomato soup here). If you haven’t tried roasting vegetables before blending them into a cream soup, I am  certain you are missing out. Roasting these vegetables gives depths and extra sweetness to the soup any home cook desires. 


  1. It’s very easy to assemble, yet resembles a restaurant-like meal. 
  2. Has deep, creamy texture that can be achieved with either sour cream or butter
  3. Enhanced by bold rosemary flavor that brings additional richness and  freshness. 


Roast cauliflower with herbs and olive oil. It might seem like a daunting task, but roasting cauliflower creates depth and creaminess that otherwise gets away. If you so wish, roast cauliflower in advance, then when preserve in air-tight container and cook later. That way you will have freshly cooked meal for dinner (for 15 minutes). 

Choose herbs wisely. They create the rich flavor you want to create  – for this recipe I like to use fresh rosemary or dried ( if you live in Europe I would recommend the dried rosemary that Kotayni offers in stores (like Kaufland). It’s unbelievably good and aromatic. 

Add sour cream (or substitute butter / coconut milk) – adding sour cream (or some butter) multiplies richness of soup and creates extra depth. 

Blend until completely smooth. It’s best to blend in stand blender rather than hand blender, otherwise soup might not get much creamier and lumps will be visible.
