Potato Leek Soup
Potato Leek soup is perfect for winter or early spring!  It’s warm and comforting and hearty and steamy…mmm  I like my potato leek soup chunky and creamy, with just a little bit of tanginess from some buttermilk.  Stay warm friends – eat soup!

Ingredients
  • 6cups sliced leeks(about 4-5 medium sized)
  • 1tablespoon olive oil
  • 2tablespoons butter
  • 1teaspoon salt
  • 1/4teaspoon pepper
  • 7 (about 3 pounds)cups gold potatoespeeled and diced
  • 1 bay leaf
  • 2-3 sprigs fresh thyme(or 1 teaspoon dried thyme)
  • 5 (40-ounces)cups low-sodium chicken broth(you can use vegetable broth)
  • 1/2cup heavy cream
  • 1/2cup buttermilk
Optional Toppings:
  • fresh chives
  • drizzle of olive oil
Instructions
  1. Trim the dark green and root end of the leeks.
  2. Slice the white and light green parts of the leeks into 1/4 inch rounds and slice in half or quarters if large.
  3. Rinse and drain leeks (see notes).  Add oil and butter to a 6-quart pot over medium heat.
  4. Add the leeks, salt and pepper to pot and sauté for about 8 minutes.
  5. Add the potatoes, bay leaf, thyme (see notes) and broth.  Bring to simmer over medium high heat.
  6. Reduce heat and maintain low simmer for about 20-30 minutes or until potatoes are tender.
  7. Remove about 4 cups of the soup and puree in blender in 2 cup batches. Could alternatively use an immersion blender right in the pot. (Make sure when blending hot items to only fill the jar of the blender 1/2 way.)
  8. Make sure to hold the lid on the blender with a kitchen towel as the lid sometimes wants to pop off when blending hot items.
  9. Return the puree to the soup pot and stir in the cream and buttermilk.
  10. Bring back to a very low simmer and serve when ready.
  11. Can be made a few days in advance, just reheat gently and don’t boil.  Can also be frozen.
Recipe Notes

Notes:

  • To Rinse Leeks: I fill up my salad spinner with water and swish them around and then drain and spin them dry.
  • Fresh Thyme Tips: I toss the thyme sprigs in whole and remove the stems at the end of cooking – sometimes I tie the sprigs together with cooking string to make easier to remove.
