  1. Preheat oven to 275 degrees F (135 degrees C).
  2. Stir garlic and vegetable oil together in a small bowl. Arrange cauliflower florets on a baking sheet; pour oil mixture over cauliflower. Toss to coat.
  3. Bake cauliflower in the preheated oven until tender and lightly browned, about 30 minutes.
  4. Melt butter in a 4-quart stockpot over medium heat; cook and stir leeks and flour in the melted butter until fragrant and well blended, 5 to 10 minutes. Add cauliflower, chicken stock, and cream; simmer until flavors have combined, 20 to 25 minutes. Stir chervil, salt, and pepper into the soup; simmer until desired thickness, 10 to 15 more minutes.

I had to make two changes only because I am limited on ingredients. I did not have heavy whipping cream, I used equal amounts evaporated milk. I also did not have chervil, I useda little dried parsley and dried chives. Even with my substitutions, this soup turned out FANTASTIC. I've had it for lunch five days in a row with half of a tomato sandwich and I can't get enough. I love that it's low in carbs and low enough in calories so that if I wanted more (which I have), I can have seconds. Delicious!

Three-star rating for misinformation. I'm in the process of making this soup now, and the temperature is way off. 275 F doesn't come close to the temp necessary for roasting. I just raised the temp to 450 which is what many recipes recommend for roasting cauliflower. Blending part of the cauliflower sounds like a good idea.

I turned on the broiler to brown up the cauliflower.After the complete soup mixture cooked for 15-20 min, I pureed 3 cups of it for a smoother,creamier soup.Added small pieces of cooked smoky ham and dusted w Parmesan cheese.Wonderful combination.

Easy and delicious. I halved the recipe since my CSA box only came with one leek. Near the end, after adding the spices, I took my immerson blender to the larger chunks of cauliflower to smooth out the soup and make it more "soupy". This is a pretty thick soup and you could stretch it a bit by doing more water or broth if you need to. Both the favors of the cauliflower and leeks were on display.

I made a few changes to this recipe, the most significant being the roasting time/temp on the cauliflower. I am not sure if 275 at 30 min is a typo or not, but that time/temp combo does not produce soft, browned cauliflower. I added an extra 10 min at 425 to the end of that cooking time. Next time I will do 20-25 min at 400. The other major change was that I added 3 strips of bacon (fried and crumbled) to the soup. Great! Minor changes included leaving out the flour (to eliminate carbs and because it really wasn't needed) and partially pureeing the soup with an immersion blender so it was thick and creamy with small cauliflower chunks. I also did not have chervil and used parsley instead. This is delicious soup and really resembles loaded baked potato soup when you top it with bacon crumbles and cheese.

Yum! I could not make exactly as written. However, if I could have it would have been just as delish, if not more. I roasted caulif in oven with baby carrots, 2 garlic cloves, drizzled with olive oil. Meanwhile, leeks were sauteing in olive oil, soon after added 3 diced potatoes. Skipped the flour and heavy cream altogether. Instead, I found a cream of onion soup in the cabinet to add to the chick stock. No spices used except for S&P. Used immersion blender to "cream" all together after simmering all for about an hour. Topped with shredded cheddar. So so so good.

With all the five star ratings I was hoping for a really great tasting soup, but it was not to be. We found it quite bland but saved it by adding a couple of very generous spoonfuls of sun-dried tomato pesto to the pot. I roasted my cauliflower at 425° as I always do. I also always substitute evaporated milk for cream to cut down on fat. The soup still had a very nice thick, creamy texture. Thank you for sharing your recipe, chefsquig.

Awesome soup....made it 2 months ago and because I haven't had cauliflower in the house i haven't made it again. Added 1/2 lb cooked bacon cut into 1" bites, and a couple potatoes cubed....Everyone loved it. The cauliflower was eaten up by our pickiest of eaters in the 12 yr old daughter.
