Why It Works
- Chopping the cauliflower into bigger florets and roasting it at very excessive warmth ensures fast browning with out extreme drying.
- Thinning the soup as wanted after mixing ensures you find yourself with an ideal consistency—not too thick, not too skinny.
One of many fantastic issues about cooking is how even a small change in approach can produce remarkably totally different outcomes. On this clean and creamy soup, that approach is the straightforward step of roasting the cauliflower earlier than simmering and mixing it, which provides a candy and nutty dimension to the vegetable’s in any other case gentle taste, making it really feel only a contact extra autumnal in that heat and comforting manner.
This is not my first foray into the world of puréed cauliflower, each roasted and never—I as soon as revealed two recipes for cauliflower purée the place roasting was the differentiating issue. On the time, I described my unroasted purée as silky and restrained, whereas the roasted model was extra complicated and nutty. However maybe extra related to this recipe is that I made clear that the distinction between a cauliflower purée and a cauliflower soup is nothing greater than thickness—the strategy for making every is similar, the one actual distinction is how a lot liquid you add to skinny the puréed greens.
That is the fantastic thing about understanding approach: Two issues which may appear totally different reveal themselves to be nearly precisely the identical. Which means that nearly every thing I stated for these purée recipes applies right here: You need to sweat your aromatics, then add the cauliflower and simmer it in a flavorful liquid like inventory, and eventually mix all of it to a clean and silky end.
I solely actually have a pair vital notes so as to add for this soup:
- Roast the cauliflower at very excessive warmth, which ensures optimum browning. On this recipe, I make some extent of chopping the cauliflower into comparatively giant florets. This helps protect a few of the extra moist inside of the vegetable and avoids it drying out excessively within the oven throughout roasting whereas nonetheless exposing sufficient floor space for the oven’s warmth to brown the outside effectively.
- The liquids are versatile, however attempt to use one thing flavorful and never simply water. I feel rooster inventory works very well right here, however anybody who desires to maintain this vegetarian can use a wealthy vegetable inventory as an alternative. I additionally add cream for some further richness, however if you would like to make this vegan you may merely omit it and use extra inventory or broth.
- Take note of the soup’s consistency and alter accordingly. I intentionally begin with too little liquid after which skinny the soup extra absolutely solely after mixing. I discover that this strategy ensures that each batch of soup finally ends up with the consistency you need whereas accounting for private desire and variables like evaporation throughout cooking. If the soup is simply too thick (will probably be), skinny it with extra liquid. You actually should not run right into a too-thin problem with this recipe until you by chance over-dilute it, so…do not try this.
- I might nearly go so far as to say the garnish on a purĂ©ed soup like this one is as vital because the soup itself, giving it a clearer identification and layering further textures and flavors that the soup itself cannot ship. To offer the comparatively easy roasted cauliflower soup base right here extra curiosity, I garnish it with a whipped, curry-spiked bitter cream. The spices work very effectively with the roasted cauliflower, whereas the bitter cream’s tang provides an vital vibrant observe. That stated, you need to be at liberty to experiment with different garnishes; they’re a simple method to maintain a soup like this sense new and thrilling even for those who’ve been consuming it for a lot of days straight.
All in all, this can be a soup that is simple sufficient to whip up on a weeknight, but additionally would really feel very at house as a starter for a fall or winter vacation meal.

Use any curry powder you want, and be at liberty to regulate to style based mostly on the curry powder you utilize, as their taste and depth can range from sort to sort and model to model. You do need the curry cream to be strongly flavored, because it melts into the soup and will probably be diluted by it.
