It’s hard to resist rainbow colored cauliflower. If I have the choice between bland white and electric green, orange, or purple, I’m going for the colors every time. This green cauliflower tastes exactly the same as the original, but because of the color it does have the edge on nutrition. I think it makes a more interesting soup. You know what else makes this soup interesting? The crispy fried shallots. They’re like mini onion rings. Load them on, and you’ll be happy.
This recipe includes leeks for their oniony flavor and a potato for extra creamy texture. Fresh parsley and sage give it a gentle herby note. Make it vegetarian, vegan, or not. I will admit that I think it needs the extra flavor boost from the chicken stock, butter, and Parmesan. But you can definitely make this without. Like I said, the crispy shallots make a huge difference, even if you’re not exactly the healthy soup type.

Green Cauliflower Soup with Fried Shallots
Ingredients
- 3 leeks, cleaned and sliced
- 2 large shallots, peeled and chopped
- 2 cloves garlic, minced
- 2 Tbsp olive oil
- 2 Tbsp butter, or substitute more olive oil
- 1 medium green cauliflower, core removed and florets roughly chopped (about 1 lb after trimming)
- 1 medium russet potato, peeled and chopped
- 3 cups chicken stock or water
- fresh sage, about 6 large leaves (you can use 1 tsp dried)
- handful of fresh parsley
- 1/4 cup freshly grated Parmesan cheese
- salt
- freshly ground white pepper
for the fried shallots
- 2 -3 large shallots
- sprinkle of flour, leave out for gluten free
- salt and pepper
Instructions
- Heat the butter and olive oil in a heavy soup pot. Saute the leek, shallot and garlic for about 5 minutes until softened.
- Add the potato and cauliflower florets. Cover the pot and braise over low heat for 20-30 minutes until the vegetables are almost tender. Stir occasionally and be careful not to brown them. Add a splash of water if necessary.
- Add the stock or water, sage leaves, 1 tsp of salt, and 1 tsp of white pepper and bring up to a simmer. Simmer until everything is completely soft, about 5 minutes or so.
- Working in batches, transfer the soup to a food processor or blender and puree. You can also use an immersion blender. Add the fresh parsley at this point and puree with the soup.
- Return to the stove and add the cheese. Reheat and taste. It will probably need more salt and pepper. If the soup is too thick, add a little water.
- Serve hot topped with fried shallots.
- To make the fried shallots, peel the shallots and slice them into thin rings. Gently separate the rings. Toss them in a little flour, salt and pepper. Shake off the excess.
- Coat the bottom of a saute pan with a generous amount of olive oil and heat over medium high heat till hot. Working in batches, drop the shallots into the hot oil and let them sizzle and brown, stirring and turning often. Don't crowd the pan, or the shallots won't crisp. They are done when they are browned and crispy, about 2 minutes or so. Remove them to a paper towel. Adjust your heat so they brown but don't burn.
Notes
Colored cauliflower doesn’t lose its color when cooked, and depending on your particular cauliflower, your soup will range from pale to brighter green. This is a healthy, mildly flavored, comforting soup. I think it goes well with biscuits, and we had ours with these.

I haven’t seen colored cauliflower for some time. I adore cauliflower soup, and I like that this has leeks in it. I love fried shallots. This looks like a bowl of perfection.
Yes they look very attractive I wonder how they grow them – do they add chemicals to the soil?
They’ve been developed using traditional selective breeding, and the pigments are natural, like the orange is beta carotene, etc.
what a great idea to use green cauliflower! Boy oh boy it looks amazing and love the addition of the fried shallots. Im always up for extra crispiness!
Your soup looks sensational! I rarely see green, or colorful, cauliflower and did wonder if they taste the same. I love the color of your soup and I bet it tastes even better. I love fried shallots on my noodle soups – what a great idea and delicious touch you added.
Thanks Monica. I do think the colored veggies are getting more common, as farmers are starting to grow them more. Pretty soon they’ll be available everywhere. It’s nice to know that the colors aren’t just decorative, but actually have some little bit of extra nutrients, too.
The purple is the one that seems to hold true color that I’ve tried. It’s so much fun to use!
That’s interesting, because purple potatoes so often fade out when they’re cooked.
Your photos are always gorgeous. I love your bowls, too. You have the mosy interesting assortment of dishes, utensils, platters.. glasses.. cups.. etc.
You have a great eye to complement whatever you are dishing up with a feast for the eyes first.
Always a lovely view.
I’d love a bowl of that soup… and maybe that bowl more! 😉
I just roasted a green cauliflower. It is much more fun in color! Love your soup, it looks wonderful and those crispy shallots look like the perfect finishing touch! Wish I had a bowl for lunch…….. sad. Love your pretty bowl too!
Those crispy shallots will definitely be making repeat appearances around here…
I think you’re right Sue – it is more interesting and absolutely beautiful. Your photos are stunning – and the crispy shallots – yum, yum, yum. Beautiful soup!
Thanks Tricia, the soup came out a little paler than I was hoping, because the green doesn’t penetrate completely through the cauliflower, or at least not in mine. I think they’re all a little different.
I’m with you. I love buying the widely colored veggies-they are so much more fun!
The only ones I’ve been a little disappointed in are the rainbow carrots, they don’t seem to have as good flavor as regular carrots.
Absolutely lovely! I always flirt with the different colors of cauliflowers, but never brought one home to play… 🙂
(btw just wrote a post about a recipe from your site, the pomegranate lime chicken thighs – will be published on Saturday, with full credit to you…)
Thanks Sally—wasn’t that chicken incredible? I can’t wait to see your post.
