It’s time for another soup with leeks in it! Leeks are such a great addition to soup.

Yes, I know I just posted a leek soup recipe a couple weeks ago, but I couldn’t help myself from making another. Leeks are just great. I love their smooth, mild onion-y flavor.

Did you know that cauliflower is a great low-carb substitute for potatoes in soup? Often, you can’t even tell the difference. As it happens, this recipe is a low-carb cauliflower soup recipe.

I used three large leeks and one head of cauliflower in this cauliflower soup recipe. I wouldn’t worry too much about the size of the leeks as they all will vary.

This soup is creamy without having any cream in it. It’s light but still satisfying.

I added the crispy bacon on top because well, why not!? That is of course optional. The fresh herb garnish is optional too, but I think it enhances the flavor even more.

Pro tip: If you need to make this soup vegetarian friendly, simply substitute the chicken broth with vegetable broth. And cancel the bacon.

I hope you will love this easy low-carb cauliflower soup recipe.

Ingredients

  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • 3 large leeks
  • 1 head of cauliflower
  • 2 (10 fluid ounce) cans chicken broth (you can sub veg broth)
  • 3 cups water
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon dried thyme
  • Salt & pepper to taste

Garnish (optional)

  • Fried bacon (3 strips) chopped
  • Fresh parsley chopped
  • Fresh chives chopped

Instructions

  1. Warm olive oil and butter in a pot on medium heat.
  2. Meanwhile, prepare the leeks (discard the top green portion and cut the bulbs lengthwise into four pieces, then chop into smaller sections). Add to the pot.
  3. While leeks are sautéing, separate the cauliflower into florets that are roughly the same size. Add cauliflower to the pot.
  4. Add chicken broth, water, ground cumin, and thyme to the pot, and increase heat to high. Once the soup starts to boil, reduce to medium-low heat and simmer until the cauliflower is tender (about 20 minutes depending on the size of the florets).
  5. Once cauliflower is tender, remove from heat and puree using a stick blender (or normal blender), using caution as the soup is still very hot.
  6. Serve with optional garnish immediately.

    We weren’t big fans of the texture, but the taste was good. Next time I’m not going to use the blender but leave the v

    I love this! I am writing vegetarian recipe round ups on my blog in 2018 (to encourage people to try meatless monday) and would love to feature you. You can check out my blog (for beginner environmentalists) at sunshineguerrilla.com. Is it alright if I share this link to your recipe?

    I made a few adjustments–roasting the cauliflower with cumin seeds, eliminating the water and increasing broth to 3 cups–and the result was the most delicious cauliflower soup I’ve ever tasted! I paired it with a loaf of homemade honey-oat bread, and my family raved about it! Thank you so much for the inspiration!

    Thank you for this recipe! I love potato and leek soup but we’ve been trying to cut back on starches and carbs lately so this was perfect. I made this while my parents were visiting and overheard my well accomplished home cook and dad in the kitchen saying “I won’t eat that, I HATE cooked cauliflower!” After he questioned each step and asked what I was going to do with “it” he decided it was good enough to try. He’s not a picky eater at all, so when he says he doesn’t like something, he REALLY doesn’t like something. He loved it, definitely making this again!
