Cauliflower & Zucchini Soup

The Adventures of Bob & Shan - Cauliflower Zucchini Soup

Rainy days are my thing. It’s not an exaggeration to say that I bounced down the stairs this morning. Bob said something like, “Babe, are you smiling because its raining?”. Yes, I was. He knows me too well. Having a rainy day meant that I opened up the windows, and decided to make soup. I love the idea of this soup, because it’s both comforting and healthy, so I quickly got to work  prepping ingredients. Bob mentioned previously that he can’t stay out of the kitchen when I’m up to something, and he proved that once again today. I was breaking the cauliflower into sizable pieces, and he suggested popping it into the oven to roast it. Smart, that way we could enjoy a roasted flavor throughout the soup! I tried to shoo him away, but I was secretly happy for the company.

Thyme, salt and pepper complimented our soup so well. That’s really all it needed! Our garden zucchini, roasted cauliflower, and baby potatoes were wonderful on their own. I decided to purée the soup a little less, since I prefer a more textured soup. Eating this mid afternoon with some Beer Bread made for a perfect pairing!

    Wonderful pureed soup!! I had to substitute a couple things due to dietary need. Any other pureed soups you could share? We have children on liquid diets and this will expand their tastes.

    I loved this! I used purple potatoes instead for a beaitiful color! I also saved some small pieces of roasted cauliflower for the garnish and this was a stunning and simple soup!

    Thanks for this great recipe.
    *I added a couple steps for anyone who’s interested:

    1. Add a couple cloves of garlic (whole) to the roasting pan with the cauliflower and zucchini. The more garlic the better!
    2. I blended the mixture as instructed, but left about two cups unblended for texture.
    3. I added about 1/2 cup of parmesan 😉

    Sounds great, question about the zucchini – do you peel before roasting? If the skin is on, I’d think there were itty bitty pieces of green / tougher slivers through the soup. Looks to be so velvety. I’m not of fan of the “texture” feel so I’d be going for silk soup.

    • BobandShan says

      It depends on your zucchini and your preference! The skin on our zucchini was still tender, so we just chopped everything up and threw it in, but had it been tougher we definitely would have peeled it first.
