Is Cauliflower Good for You?
Is cauliflower good for you? That would be a resounding yes.
Cauliflower, a cruciferous vegetable, contains unique plant compounds that are helpful in preventing cancer and heart disease. It’s also low carb and full of healthy fiber.
Cauliflower Rice anyone?!
Cauliflower Nutrients
This incredible vegetable also contains:
- Vitamin C
- Vitamin K
- Magnesium
Cauliflower is one of my favorite foods. A cruciferous vegetable, it’s full of anti-oxidants, anti-inflammatory compounds, and healthy fiber.

Wow – weird, I made a similar soup myself this week – but I added in a head of roasted garlic. I think this might be my new favorite soup! http://tasty-yummies.com/2012/01/31/creamy-roasted-garlic-and-cauliflower-soup-gluten-free-and-vegan/

I normally hate cauliflower (texture thing I think) but I made this soup for my wife and I and it was wonderful… Ended up drizzling top of the soup with chopped green onions and a little lite cheddar cheese …
Amanda Jackson says
I made a Paleo version of Cauliflower gratin with bread crumbs from your sandwich bread! It was amazing and creamy!
Carmel says
Hi Elana,
just wondering if you’ve ever cooked soup right in the vitamix… this one could probably work? Just saute the onion and throw it all in? I am new to my Vitamix and looking for soup recipies.
Thanks!
Rachel says
Hey Elana,
This recipe looks awesome. I love cauliflower, and I’ve been trying to find ways to eat lots of vegetables a la the Terry Wahls version of paleo/primal.
Have you seen this video? It is definitely worth 18 minutes of your time if you haven’t.

I’m not a huge fan of raw cauliflower…and until recently, didn’t even know it had much nutritional value. I guess that white color threw me off. Your soup sounds delicious! This is cauliflower I know I will love.
Tressa B says
I made this the other night and it was delicious!!! I chopped up the cauliflower before roasting it, and added some whole cloves of garlic to roast as well. Then I topped the soup with some blue cheese and bacon crumbles. It was amazing! I’m having the leftovers for lunch today and I’m so excited!
Tressa B says
Okay, it was even better today. All the flavors have had time to combine, and i can really taste the garlic now, although it’s still very mild. I will be making this soup again and again! Thanks for a non-boring cauliflower recipe!
