Roasted Cauliflower and Broccoli Soup: Perfect for Fall

Cauliflower and broccoli have a deep flavor after roasting that they simple miss when you steam them. The high heat of the oven takes away the bitter taste that some people hate and makes these vegetables sweeter.

If I serve raw cauliflower and broccoli - everyone complains. If I roast those same vegetables - they disappear. They are totally different animals.

I have featured both

oven roasted cauliflower and roasted broccoli - and these are the precursors to this fantastic soup.

Put the vegetables on a rimmed baking sheet (the parchment paper is there to make it easy to pick up the vegetables and clean the sheet). You roast at 450F for 20 minutes.

The roasting is the actual cooking of the soup in this recipe.

I puree 1/2 of the cauliflower and broccoli in a blender to make “cream” and add a little half and half to make the soup really creamy. This way you cut calories without noticing (my favorite way).

The half and half is a flavoring agent because people love “Cream of SOMETHING Soup”. Can you blame them? This soup is so low in fat and calories that the cream is no big deal. Obviously, if you are eating beer cheese soup it is a whole other ball game.

You don’t have to add the half and half if you want to turn this soup into a vegan one.

When you add the cream, it changes if it will freeze well. If you want to make a big batch for the freezer, leave out the cream until you heat it back up for consumption.

Feel free to substitute for the cream with soy milk or whatever kind of nut milk you have on hand.

I really enjoy soup all year round. Creamy textured soups are the best. A vegetarian restaurant I've gone to for years has the best soups - all kinds. Squash, dal, African peanut - all sorts of vegetables. Inspired to make similar soups at home, an immersion blender has become my best friend! Thanks for this recipe to add to my rotation, and also for the tip to leave the cream out if freezing for later.

We always have fat free milk in the refrigerator. I will use fat free milk instead of half and half. Fewer calories and fat. I think this soup will be awesome with sunflower seeds and fresh cracked black pepper on top!
