Roasted Cauliflower + Wild Mushroom [Vegan] Bisque

by Sarah on October 22, 2013 · 14 comments

I grew up in the Mushroom Capital of the World, but I never liked mushrooms.

And then a few years ago, I started to become rather obsessed. My favorites are actually raw, white button mushrooms, which is the least exotic of all the mushrooms. Ever.IMG_5250 (1024x683)

That doesn’t mean, however, I’m not excited to try more wild varietiesIMG_5998 (1024x683)

especially if they are sent for free as part of a recipe contest/challenge. :)IMG_5979 (1024x682)

When Marx Foods contacted me to be a part of their ‘Shrooms for Soup recipe challenge, I couldn’t say ‘no.’shrooms_for_soup

But instead of just sticking to ONE type of mushrooms, I used all three.*

*Three is a magic number after all.IMG_6225 (1024x683)

I had some pretty delicious inspiration in the form of this local Roasted Cauliflower Soup with mushrooms and local turnips from Epiphany, here in Tuscaloosa. What I loved about it was you could really taste all of the components without the drowning (and diluting) effect of too much heavy cream.IMG_20131016_184836_436 (1024x575)

My soup is similar: it is essentially straight-up veggies masquerading as ‘bisque.’

Let’s just say they showed up to the Halloween costume party a little bit early?IMG_6557 (1024x683)

It starts with frozen cauliflower.*

*Cheaper, easier, and much more practical when you know it’s going to soon experience death-by-processor.

Roasting it cuts the frozen taste, but it’s still soft enough to blend easily (and with fairly smooth results).

Rinsing and then soaking the dried mushrooms overnight gives you not only soft and tasty mushrooms, but soft and tasty mushroom broth as well.IMG_6185 (1024x682)

From there it’s a matter of blending and seasoning.

(And perhaps a taste test or two, followed by more blending and more seasoning.)

Honestly, I loved it just like it was. Cold.

But I’m a little crazy.IMG_6245 (683x1024)

Heating only enhances the flavor. And waiting a day or two to eat it? Well it doesn’t take magical mushrooms to convince you that every soup tastes better the next day (or the day after that).IMG_6255 (1024x683)

It will not, however, get any more photogenic.IMG_6564 (1024x683)

I had always hated mushrooms until this summer I tried some baby button mushrooms raw and for some reason I fell in love and can’t get enough since! I love them all and just recently ordered a whole bunch or dried so I will definitely be trying your recipe! :)

Another MUST MAKE from the Smart Kitchen! I always forget how much I love dried mushrooms! They’re so much more flavorful than regular! Also, nutritional yeast and cauliflower are a match made in heaven. Need this soup in my life ASAP.

I love mushrooms, but I had not idea there was a mushroom capitol. I’ve also never used dried ‘shrooms. This looks fantastic. I really like the cauliflower to thicken it! I just wish we could have summer temps and still eat soup. I’m cold.

Unlike you, I’ve TOTALLY been having a mushroom thing lately. Sadly, the cauliflower here in Taiwan is….more like wilterflower. It’s the saddest thing I’ve ever seen. And I don’t have a food processor. I guess I should just pin this recipe for when I get back to the states? Thanks for another goodie :)


Brittany @ Delights and Delectables October 22, 2013 at 7:06 pm

You are killing me lately with these recipes!!! I love me some mushrooms!


Heather @ Better With Veggies October 22, 2013 at 7:59 pm

Oh I love me some mushrooms!! This looks delicious girl – you win first prize from me!!

I want to make this! YUM! But I’m curious about roasting frozen cauliflower…do you need to add any oil to it before roasting? If not, don’t the chopped onions get a bit burnt when roasted…or not because the cauliflower is so wet? Do you roast the cauliflower from frozen, or thawed? Thanks!


Sarah October 23, 2013 at 12:16 pm

Thanks for asking! I might let the cauliflower sit out of the freezer for a minute or so, but it is still pretty frozen when I pop it in the oven. However, I’ve roasted thawed cauliflower before and it works just as well–you have to adjust the time though. I roast it covered, which helps keep the moisture in, so the onions don’t get burned. Also, I lightly spray everything with canola oil, but not a lot of that!


Heather @ Kiss My Broccoli October 24, 2013 at 2:10 am

I can’t blame you for eating it straight up…I can totally see this as a dip for some toasty baguette pieces or salty pretzels! Yum!

And now I must confess a few things: I’ve never made anything with wild mushrooms because I’m intimidated by them! I always clear out the mushrooms on a veggie platter…they’re good in ranch dressing, but my favorite dip is ketchup! As much as I love raw mushrooms, I think canned ones are better on pizza!
