Creamy Mushroom and Roasted Cauliflower Soup

Creamy Mushroom and Roasted Cauliflower Soup

Ever since I made the roasted pumpkin, pancetta and sage soup a few days ago I have found myself thinking about soups more often. After avoiding soups during the hot summer days I am now free to make them whenever I want and that is good because I have a few ideas that I have been wanting to try! Up first was one for a cream mushroom and roasted cauliflower soup! Cauliflower works really well as a thickener in soups and I was thinking that I could use some to make one of my favourite soups, cream of mushroom soup, a bit heartier.

Creamy Mushroom and Roasted Cauliflower Soup

A few years ago I discovered that roasting vegetables very often makes them better and I have been roasting pretty much any vegetable that I can get my hands on ever since. Cauliflower is no exception to my theory and in fact it is one of the shining examples of it as roasted cauliflower is so addictively good! I could literally eat a bowl of roasted cauliflower just like a bowl of popcorn and I have often made it just to snack on. Using the flavour enhanced roasted cauliflower in soups is also amazing and I could not resist the opportunity to use it in this recipe. Although roasted mushrooms are also really good, I wanted to saute them and let them caramelize a bit to build up their flavour and then to deglaze the pan with some white wine to make sure that we get all of that caramelized mushroom flavour from the bottom of the pan. I finished the soup off with some garlic, leeks, thyme and a healthy dose of heavy cream to make sure that the soup was indeed creamy.

I really like how simple two ingredient soups very often turn out to be so insanely good and this creamy mushroom and roasted cauliflower soup is no exception! If you are a fan of mushrooms then this is definitely a soup for you! You can use pretty much any type of mushroom that you want and I like wild mushrooms and I tend to go with a base of cremini and then add in some shiitake, oyster and even shimeji mushrooms. I served this mushroom and cauliflower soup with garnished with even more sauteed mushrooms along with some garlic rubbed crostini. I also happened to have some pancetta and blue cheese on hand and I could not resist trying my second bowl garnished with them! The tangy blue cheese and salty, crispy fried pancetta went really well with the creamy mushroom soup and I highly recommend it.

Note: I like my soup nice and thick, but if you prefer a smoother soup you can use only a half a head of cauliflower instead of a full head.

Mushrooms Canada said...

Wow Kevin! This would be absolutely satisfying on a cold night like tonight. I tend to like my creamy soups very thick as well... And great mushrooms choices! I too tend to use crimini's as a base and then add in oysters and shiitakes. Garnish with enoki and you're all set!

Wow! The soup looks really creamy and thick! I'm sure that I could trick my sister into eating cauliflower (she hates any kind of vegetable, except for mushroom, and she likes creamy mushroom soup).

Our weather here in the midwestern USA is starting to get colder, and this soup looks absolutely wonderful! This recipe definitely goes on my "must-make" list.


Kathryn said...

Sigh . . . this was what I was TRYING to accomplish last time I made roasted cauliflower. Yours looks much better, so I guess I'd better use this recipe next time! :)

Julie said...

I too don't make many soups throughout the summer, so now its time to get back to them. This looks and sounds so great it will be on the menu for this weekend. Thanks.

Maria said...

Claudia said...

I came late to cauliflower - just didn't see the appeal - until I roasted it. So this does entice.

dongala (wanderer) said...

Helene said...

This soup looks like it has the perfect creaminess. Since I've started to roast cauliflower my kids became addicted to them.

Karen | Divine Dinner Party said...

A soup that warms my stomach and heart by just looking at the photos! Can't wait for winter so that I can make and eat soup everyday (or at least, every other day?)LOL!

Nina said...

Kevin you and I are veterans in the blogging game, but I can truly say you are like a good red wine, it gets better and better. The soup and your styling is magnificent!

Unknown said...

I use roasted cauliflower as a base for so many things . . . when I make soup with it, I don't add the cream (cut the calories in the soup so that I can have dessert! ;-) Love the twist of adding the sauteed mushrooms and as the weather gets a little cooler and rainier out her on the west coast, this will fill the bill! Always good to have extra servings in the freezer for lunch!

sailingsam said...

Tried it but use low fat cream...came out good...

Just finished making a pot of this soup :) I used slightly caramelized onions instead of leeks and only button mushrooms (hoping I won't regret using a variety).

It turned out so tasty! I like this slight hint of thyme that isn't overpowering.. Chunky soup in the winter is great so I do not mind the texture.. may want it a little smoother but I only have a 4 cup cuisinart :(

Anyway! I will be pairing this delicious soup with a slice of focaccia made from the organic bakery I work at :) Nomnomnomnomnomnom

Kelsey said...

I seriously swooned when I saw the photo. I like my soups thick too.. more like a gravy consistency. Canned soups are always so... soupy lol

Becky said...

I made your wonderful soup recipe last week. It was a rainy day & I had everything except the shitake mushrooms. A quick trip to Trader Joe's & I was set. The smells comming from the kitchen, had my husband repeatedly checking to see how much longer it was going to be.

I only recently discovered your site & can't wait to try some of your other recipes.

Thank you for the recipes, the informative commentary & the beautiful photos!

Hi Kevin,

Thanks so much for this recipe! I made it last night and it was absolutely amazing. My husband and I finished the whole pot by ourselves!

I'm looking forward to reading about (and trying recipes from!) your culinary adventures in 2012.

I just found your blog and this is the recipe I've made. Holy crap, it's delicious! I added a little grated swiss cheese, and it was the best soup I've ever made!

I just made this and we left off the blending and cream at the end and IT.WAS. AWESOME!! Thanks so much for the recipe! This will be one I will enjoy over and over again! Also, I think this would be awesome over a roast or if you added chicken!!

BTW, I did change up the cream to 1/4 FF canned cream and 3/4 skim milk. Didn't miss a thing.

How is this when reheated? I'd like to make this for a friend who is busy with multiple jobs and taking care of his mother. He's recently gone veg and I think he would love this.
