Cauliflower. I doubt she’s anyone’s favorite vegetable. Tomatoes, asparagus, and her far more popular cousin, broccoli, usually get first billing. No one talks about their, ‘first head of heirloom cauliflower” for the season. No one waxes poetic about cauliflower. But I do like cauliflower, as long as I’ve jazzed it up a bit. I like it mashed with butter, but my favorite way is Indian style with toasted cumin seeds or curry and a bit of butter or ghee*.

The latest issue of Cook’s Illustrated came out with a recipe for Creamy Cauliflower Soup. I love Cook’s Illustrated because they explain the extensive testing process for each recipe. But all I could think of was curried cauliflower soup…with crispy onion bits…and toasted cumin seeds…and a bit of drizzled ghee. Cook’s recommended cooking half the cauliflower first and then adding the remaining florets half way through, for more texture. Pulse it in your food processor or blender or puree it for a smoother soup.

The way the writer described the soup, it sounded as though he’d tasted the best thing in the world! It was worth a try. This curried cauliflower soup recipe uses just water, no chicken broth, which is my usually cooking stock. Using just water makes it vegetarian. Substituting the butter or ghee for another fat and it’s vegan as well. With no flour, it’s also gluten-free and Paleo! I think I’ve pretty much covered it all!

Spencer loves this curried cauliflower soup! OK, so he’s easy to please. But when he points the spoon at the bowl and nods his head because his mouth is full, that’s a good sign.

Indian Spice tin

I keep my Indian spices in this little tin. The colors of it are so wonderful. I use them all the time, not just for Indian food. Curry powder comes in hundreds of different blends, I used 2 tablespoons of a mild version and it was perfectly spiced for my 12 year old. Not too hot, just a nice finish. Use less or more depending on your taste. Crispy onions-I never make enough. I should make a note of that. If you’re looking for more vegetarian or vegan recipes, try Butternut Squash with Toasted Cashews, Wild Mushroom or Vichyssoise.

I  hope you enjoy this curried cauliflower soup recipe and add it to your fall soup rotation!

*Ghee is Indian clarified butter with the milk solids skimmed off. It has a much higher smoking point than regular butter. Unlike regular clarified butter, ghee is cooked for a much longer time giving it a rich nutty flavor. It can be purchased in Indian grocery stores, most health food stores and Trader Joe’s markets all over the country. Regular butter can be substituted, but needs to be watched more carefully to prevent burning.

  2. Okay this sounds so good to me, I really want to try it. But I’m confused — how do you get the onions to crisp? When I saute onions in butter, they get soft. Is it the butter/onion ratio that does it? Is it a higher cooking temperature? Thanks!!

    1. Katie, I fry them in small batches so they don’t get too crowded. Also, if you don’t have ghee, use oil which has a higher smoking point than butter.
