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

Cauliflower is one of my favorite foods. A cruciferous vegetable, it’s full of anti-oxidants, anti-inflammatory compounds, and healthy fiber.

Laura @ Gluten Free Pantry says
I don’t soup gets any easier than this-can’t wait to make this recipe!
Jay says
Wow Elana, I’m shocked and quite dissapointed. Your “I’ve de-Paula Deened” comment was a low blow, and totally uncalled for.
Not everyone likes Paula Deens style of cooking & baking, not everyone likes your style of cooking & baking, nonetheless they both exist for people to choose from. Yours is not to judge who’s cooking & baking that should be.
I don’t have any Paula Deen books, I’ve never cooked a Paula Deen recipe. I do however believe Paula Deen is good person who genuinely cares about others.
I also believe Mocking/dissing a fellow cookbook author as you have done, is petty and mean.
There was no need to associate Paula Deens name with this recipe, as it is not her recipe.
A simple, “I’ve adjusted the fat & cream suggested by Bon Appetit” would have been more appropriate.
Reading your entry has been a major dissapointment. My thoughts of Elanas pantry, have changed completely.
herbalchef says
I totally agree! I do not watch Ms. Deene’s shows, do not make her recipes but do not believe she should be slam blasted by another author. Shame on you Elana. The comment was uncalledfor!
Latia says
Aaahh, don’t be mad at Elana. Everybody knows that Paula Deen represents cream and butter. Often (always?) in her show as she’s adding a cube of butter or a cup of cream to her recipes, she says, “and maybe a touch more,” and adds another cube or cup. It wasn’t a slam, per se, it was like using a verb, de-Paula Deened.
Mia says
I feel the same as Latia. When I read, “I’ve de-Paula Deened this recipe…” I knew exactly what she meant. It was perfectly descriptive of what she did to the recipe (if you have ever watched Paula Deen cook).
If you watch the Food Network you may have noticed Bobby Dean (Paula’s son) has a new show called “Not My Mama’s Meals”. In that show he is trying to de-Paula Deen his mom’s recipes (by making them leaner and lighter).
And I find it very curious at how much reactivity there is towards Elana from Jay, Frances and herbalchef. There is always something to learn from one’s own reactivity, if one is curious enough.
Jan says
I so agree. I didn’t experience it as a diss at all, just descriptive. C’mon this is a private blog. I want for Elana to be able to have a personality without being so careful that she has to be sanitized. Elana cooks differently than Paula Deen. God help us if we always have to be politically correct.
I love cauliflower and have just cooked up a batch of Ina’s chicken stock — six delicious quarts which I’ll use in this recipe.
Michelle says
Amen.
Angela says
I agree with the others. This was not a slam on Paula at all. The woman’s name is syononomous with cream and butter and it was pretty obvious what Elana meant by her comment.
Frances Brooks says
Could not agree more. I am perplexed.
Frances Brooks says
I want to clarify I agree with Jay’s comments.
Krisy says
You silly people… How easy it is to offend some of you these days! There is no sign of malice in Elana’s comment, but you are pretty offensive (and not very accurate) in sharing your opinions about it. You should become educated about Paula Deen and her cooking; anybody that watches her on tv knows that she the heavy use of butter and cream in her recipes is a trademark quality of her cooking. It is one of those comments that reasonable people understand, and we roll our eyes and dream of the days when we ate like that and enjoyed it without remorse! (Before many of us were educated about food and nutrition, or before we discovered that we’re bothered in some way by diary or gluten.) How about demonstrating your intelligence by being understanding in your attitude toward comments and like this, rather than leap to offense.
Magda says
I agree. I got peeved at first, then thought about it and realized it’s a harmless comment. Then again in itself eating butter and heavy cream is not bad (if one can eat dairy without issues). Butter is a very healthy fat. And I don’t believe it’s to blame for Paula’s problems. All that sugar on the other hand cannot be good for anyone.
Jay says
“How about demonstrating your intelligence by being understanding in your attitude toward comments and like this, rather than leap to offense”
@krisy
How about you demonstrating your intelligence by understanding it was in extremely bad taste for Elana to mock/diss Paula Deen, when she had nothing to do with a recipe Elana garnered from Bon Appetit.
Paula Deen is not perfect, Elana is not perfect. You are not perfect, I am not perfect. None of us are perfect. We all have different ways of doing things, eating, cooking & baking included. Not one of us has the right to mock/diss another for not doing things the way we do.
Bottom line.. Paula Deens name should never have appeared in Elana’s posting. It was uncalled for, mean, & disrespectful.
Annie says
Jay, you seem a little het up over nothing much…chill out dude coz you’ a tad over sensitive and lets get back to the fantastic cauliflower soup.
HiDee says
LOL!
I agree with Annie.
Dee Ruff says
I think Paula Deen and all of us (especially people like me who are battling truly serious health issues), would be better off not worrying about semantics and whether or not you are protecting rich (and fat/unhealthy) celebrity foodies (who are making a ton of $) and take a peek at the video on this website. http://www.terrywahls.com. Take the time to watch the video she created for Ted.com about mitochondria and your heath/diet choices. And maybe consider adopting some of the ideas on the video. Or get Dr. Wahls’s book. And instead of sniping at Elana, be greatful for the health that you have, and get a grip. And enjoy the great, healthy recipes on this.
Dee Ruff says
*meant “grateful” of course, typo error.
Dee Ruff says
Here’s a great link to Dr. Wahs’s video presentation. http://www.terrywahls.com/current-information
Michelle says
“greatful” is the perfect typo for this food blog!
Mia says
Thank you for the Terry Wahls link!
Holly Morgan says
Dee,
Do you have a restaurant in Louisiana?

Michelle Perkins says
I couldn’t agree more – Jay you need to chill out… it’s just a recipe blog.
Jami Fynboh says
AMEN!
Judy says
Hey, lighten up a bit. I knew exactly what she meant with the comment. It wasn’t said in a derogatory way, just as an offhand comment.
Audra says
wow are you seriously going to rag on Elana for saying something about Paula Deen? She just commented on how her version is healthier…don’t get your panties in a twist.
Gwen says
I didn’t see it as a diss. I read it as she just changed Paula Deen’s recipe.
heidi says
Curious, since you test all things every which way, why not chop the cauliflower before baking? Is there a particular reason? And, yes, it’s a favorite. Thanks!
Pat Mayer says
What is the calorie content for Cauliflower soup?
Margi says
I *love* cauliflower. It’s a beautiful sub for high-carb potatoes and rice. It’s delicious by itself and yet it can play well with other foods. Cauliflower is the delicious winner of my food beauty pageant. :O)
Katie says
Mmmm…the chive oil (from the original recipe) looks pretty good too. Isn’t it amazing how much better things taste when you just let them be themselves?
Kate @ The Cheeky Bite says
Yum! Love the simplicity of your recipe! I love mashed cauliflower and I recently tried this recipe from Living Without magazine for roasted garlic, cauliflower and celeriac soup. I left out the gluten-free croutons, and it was fantastic. Plus, the garlic smells heavenly as it roasts in the oven.

jo @ including cake says
I love cauliflour simply steamed and then mixed with leek and potato and covered with a lovely vegan cheeze sauce. P.S Just wanted to say how much I loved the visual simplicity of your blog, so many blogs get overcrowded, and I too have been trying to keep mine nice and simple (though i still have a newbie blog so it makes that easier to do!)
Megan says
I love to do this although I usually cut the head of cauliflower into smaller pieces, add a little olive oil, salt, pepper and sometimes so garlic powder or cayenne and roast the pieces under they’re golden brown. Then i add them to the broth and sauteed onions and cook until they are soft enough to blend. Although I’m sure the cauliflower gets perfectly roasted this way too. It just takes longer. :)
Urban Wife says
I love having another use now for cauliflower! Thanks for a great (and simple!) recipe.
