Roasted Cauliflower Soup
Recently I wrote that most of the soups I make are one-pot meals. But after reading research that says people who begin a meal with a light vegetable soup consume fewer calories than those who don't, I started thinking about making more starter course soups. I had a cauliflower in the fridge and a meal that needed more vegetables in it, so I whipped up this creamy-tasting soup.
Frankly, I can't even remember what I served with this because the soup was the star of the meal. I had worried that E wouldn't like something so simple and basic--roasted cauliflower allowed to shine on its own without lots of seasonings--but she devoured it. I'd also been concerned that the truffle oil, which gives the soup a rich, woodsy taste, might not be to her liking, but obviously I was wrong. From now on, Roasted Cauliflower Soup will be on the menu regularly.

Roasted Cauliflower Soup
(printer-friendly version)
I used a blender to get this silky smooth, but a food processor or hand blender might also work. Be careful not to burn yourself opening and pouring from the blender because the mixture can be super-heated.
1 cauliflower (I used an orange one)
1 onion, cut into wedges
2 cloves garlic, peeled
4 cups fat-free vegetable broth
1 large potato, peeled and cubed
1/4 teaspoon freshly grated nutmeg
salt and pepper, to taste
4 drops truffle oil (optional, but good)
Smoked Spanish paprika, to garnish
Preheat oven to 400. Cut the cauliflower into florets and place them into a large baking dish sprayed with oil. Lightly spray the top of the cauliflower with oil. Bake for 20 minutes. Sprinkle the onion wedges and garlic on top of the cauliflower, spray lightly with olive oil, and return to the oven. Cook for 20-25 more minutes, stirring once halfway through.
While the vegetables are roasting, heat the vegetable broth and add the chopped potato. Bring to a boil and reduce the heat. Cook covered on very low until cauliflower is ready.
Add the cauliflower mixture to the broth. Puree it, in batches, in the blender until very smooth. Return it to the pot and add the nutmeg and salt and pepper to taste. Simmer for 10 minutes. Just before serving, stir in a few drops of truffle oil, if desired. Ladle into bowls and serve, sprinkled with smoked Spanish paprika.

Holler at Tinned Tomatoes and Lisa at Lisa's Kitchen are hosting a monthly blogging event called No Croutons Required. This month's theme is one that I can really get behind--vegetarian soup! I'm sending in this soup as my entry, which, now that I think about it, would taste great with croutons.

this looks great! I have a cauliflower in the fridge and usually just roast it (and eat the WHOLE head!) but I may try this as something different!
WOW this looks fantastic! I will definitely be making this one soon. One question though- where might I look for truffle oil? I have never seen it.
Laura, I found it in a local gourmet shop, but you can buy it online. It's on the expensive side--$12 or more for a tiny bottle--but you use it by the drop, and it imparts a deep earthy taste to sauces and gravies. Since it's so expensive and not easily available, I marked it as an optional ingredient, so don't feel that you have to have it to make this soup.
You might also try TJ Maxx for truffle oil (and smoked paprika, too). The one near me has a food aisle and although you can't always find what you're looking for, you can often find these interesting expensive things for really cheap... (I got a large bottle of truffle oil for something like $6 and it's every bit as good as the really expensive tiny bottle I'd bought first!)
I recently found your blog and now I am hooked. I look forward to trying your recipes.
I would echo the TJ Maxx suggestion....it is always random but sometimes in that little food aisle you can really get some decent deals. Besides, even though it is inexpensive there, it doesn't mean it wasn't considered a higher value at the original store that stocked the item. I got a HUGE jar of Herbes de Provence (probably 3x the usual amount) there for only $6.
Great recipe Susan (as always!)Wouldn't it figure, though, that last night I used up my entire head of cauliflower doing my interpretation of your curried cauliflower dish? It was delish....and with this posting looks like cauli' is back on the list for next week's grocery trip!
Your soup looks great. The first time I made a creamy cauliflower soup I was also afraid the kids wouldn't like it, but they loved it and would ask for it often. They also loved creamy broccoli soup, carrot soup and butternut squash soup—all so easy and healthy.
I've never tried truffle oil, but we have a Penzeys spice store nearby and I'm hooked on their smoked Spanish paprika and chipotle powder.
hi susan! i just made this tonight, and it is SO good.
i didn't use truffle oil and doubled the garlic (i love it).
the soup is creamy and soothing and full of flavor. and so simple!
(i'm very glad that i live alone and made the whole recipe, now i get to freeze the rest!)
Where were you reading about the starter soup = consuming less calories? I'd love to get more information on that!
Thanks for the recipe. I am a vegetarian following Core, and I always rely on you for good ideas. The cauliflower is roasting in the oven now... I'm going to leave the potato out to make it "unlimited core". But I hope that it is still good. If I need to, I'll add the potato in next time I make it. I have a feeling there WILL be a next time.
Thanks again!
yr soup is gorgeous
Yum! It's pouring with rain, and unseasonably cold here, so my half-head of cauliflower is in the oven roasting now, and we're looking foward to lovely warming healthy soup for dinner. Thank you!
Your soup turned out beautiful!! I will have to try this recipe, it sounds lovely.
I recently made a roasted cauliflower soup that was disappointing, and so I am now hep to trying your treatment. Away I go to add truffle oil to the shopping list!
For those who have a Trader Joe's in their area they have very reasonably priced truffle oil. I have recently gotten totally hooked on cauliflower. My CSA delivered some to me and now I can't seem to get enough of it. I think the orange is so pretty. I understand there is a purple variety too and that both colors are the result of selective breding and not genetic engineering. Its all good...
I love soup! But I'd be afraid that I used them as a starter course, I would end up consuming MORE calories. I'd fix a large bowl and then want an equally large plate of the main course.
I don't know how to stop eating when I'm full. I only stop when the plate is empty. I'm working on portion control for the New Year. But I will try this but as a main course with some good crusty bread.
Susan--this looks absolutely wonderful. Fabulous for a cold night like tonight.

This must be a soup kind of day. It's been raining all day where I am...puts me in the mood for something just like this! :)
With this Truffle oil, it should be wonderful, and maybe little nice earthy flavored ? I have never tasted this oil yet.
I cooked this for my sometimes reluctant "vegetarian" wife who happens to love both cauliflower and potatoes; myself not being a fan of cauliflower in general.
We both loved it!! I used an orange cauliflower and a bit more truffle oil for zest. Unbelievably low calorie and delicious.
This soup looks fabulous. And since I'm already a fan of both cauliflower soup and roasted cauliflower (though never thought to combine the two), I'm sure I'll love it! Sounds like the perfect meal to me.
I've never been keen on cauliflower but i've never tried roasting it... most things taste much better roasted too! thanks for the idea
One of my all-time faves. Always tastes creamy and sinful--but it's not!
Neat looking recipes, almost makes me feel like trying them. I used to eat cooked vegan, but since converting to an 811rv diet I can't stomach most of these things any longer, at least I can look at them. Keep up the good work.
Oh wow! The color of that soup is outstanding! It looks so insanely creamy, I still don't believe how low in fat and calories it really is. Wow......Bravo!
yum, yum, yum. i love delicious pictures of soup. cauliflower soup is on the dinner menu for next week, and i've been thinking about whether to roast first or whether to make it like broccoli soup (all in the pot) - i think i have my answer. i don't have any truffle oil, but i'm thinking some roasted hazelnut oils would also be a nice complement to the cauliflower.
again, yum.
This is a really nice recipe. I just made some for dinner tonight and have to leave my compliments.
Also I didn't have any truffle oil on hand and it being 2 degrees outside I opted to skip it and try something else. A drop of Mexican chipotle sauce gives a nice kick!
That's a new one on me. Sounds great - I'm going to have to try this!
Loved the soup, but couldn't resist the urge to tinker.... I added 1 head of swiss chard to the broth, and while it turned the soup a greeny color, it was quite delicious. this was my first time cooking one of your recipes - yum!
I had this soup last night. It is excellent!
:)
I made this for dinner tonight for a group of friends. It was a tasty hit!
Tried this tonight - Serious Bunny and I both loved it! Thank you :) We didn't have any potatoes but it didn't seem to matter - a really nice, sweet, subtle soup.
I want this so much right now, even though I've just eaten supper. I think I'm going to make it tomorrow.
I have stared at the pretty pictures and read through a lot of your recipes, and I finally tried one. This was delicious!!!
Wow, Ive been entertaining winter soups for the past few weeks at (nomeatfor.us) and this one looks like an excellent addition. Will try very soon.
I was looking for a cauliflower soup recipe after tasting a friends and was excited to also see the use of truffle oil! I had gotten some for Christmas and hadn't had a use for it yet and it was so good in this soup. It hit the spot on this cold winter day. And low calories to boot? Awesome! I will be visiting your site more often!
Oh dear mother of god...This soup is just great!!! Right now I'm having a bowl - I did some variations: roasted the garlic in foil and also roasted some almonds and cashews I had left. It's like it had loads of cream!!! At the end, I sprinkled parsley and chives...My little baby son will love for sure! He loves the creamy stuff!!! Huge compliments to your healthy ideas!
Just happened upon your blog today as I googled "cauliflower soup". Thanks so much for guiding me through this tasty soup! The taste is fantastic and my parents who are currently on a strict diet, will be able to enjoy this tonight!
Oh my gosh. This soup was so good. I think I'm going to cry.
