When I make homemade chicken broth I always add 1 teaspoon of turmeric, thats is why the color of this soup is more orange. Feel free to add 1/2-1 teaspoon of ground turmeric for that extra benefit of turmeric, color and flavor.

    Made this last night for dinner. It was so flavorful and filling. My family went back for seconds. I will definitely make this again.

    Simple, very satisfying. I added some fresh rosemary and minced garlic during the sautee, they went well with this dish. After releasing pressure I added some chopped swiss chard greens from my garden for color (cooked just till they wilted) and a 1/2 of cream to make the soup a little richer. Thank you very much for providing this recipe, it’s a perfect cool / cold weather comfort soup!

  3. I received leeks in my CSA bag this week and had no idea what to make. I found this recipe and I had everything in my fridge. I’m vegan so I used no-chicken broth. Boy, was this quick, easy and SO delish!

  4. 5 stars
    Awesome recipe! Was terrific made in a good ole Dutch oven. I had bacon chopped for a leek and potato soup so used that and a drizzle of olive oil instead of the butter. It is a new fave, thanks!
