My eyes light up when I see leeks in my farm share, and this soup is never far behind. I adapted the potato leek soup recipe from Joy of Cooking to come up with this version that my family loves.

  2. I adore potato and leek soup! The recipe I use I adapted from one in a Sicilian Soups cookbook. I usually make it with a little bit of extra cream and add a little bit of lemon juice for some kick. The bacon fat sounds so great, though- I’m going to try this version and see what I think!

  3. Love potato leek soup – my kids don’t always though. Some of my children do not love mashed potatoes. I make a similar recipe but use cauliflower instead of potato. All the kids love it as do my husband and I. I add a small bit of flour to the bacon fat and leeks – add some broth or milk to thicken the soup base. Then add cauliflower. Blend and ready to go.

  4. I’d sweat the leeks in olive oil till they were soft then add in cubed potatoes plus vegetable stock. Cook till the potato is starting to break up then serve with some bread. no need to blend

  5. I am always happy to see leeks in my farm share, too. And I keep bacon fat on hand! Great minds think alike.

    The soup looks extra delicious thanks to your gorgeous photos!

    1. Thanks, Kirsten! I’m enjoying playing with my new camera. Hopefully I’ll figure out how to move into manual mode soon.

  6. One of the best combinations ever-leeks and potatoes. We love Julia Child’s version with just leeks, potatoes, water, and salt. Amazing!
