Ingredients

  • 4-5 cups leeks sliced ¼ inch thin
  • 3 Tablespoons Olive Oil
  • 2 Tablespoons Salted Butter
  • 4 cloves garlic minced
  • 1 Tablespoon fresh Thyme or 2 stems
  • 2 pounds thin skin potatoes sliced ¼ inch thin (yellow potatoes were used here)

  • 1 teaspoon of salt or more to taste
  • ½ teaspoon black pepper
  • ½ cup sour cream
  • Fresh Thyme Leaves Fresh chopped parsley leaves, or chopped chives for serving garnish.

  • Optional: Make a batch of Leek oil using the green tops to add a colorful and flavorful drizzle as a garnish.

Instructions

  • Slice the green tops off the leeks and set aside.
  • Using a sharp knife or mandolin, thinly slice the white portion of the leek to approximately ¼ inch wide.
  • Using the same method as above, thinly slice the cleaned potatoes. Set aside.
  • Add the leek slices to a strainer and rinse thoroughly under cold water to remove dirt.
  • Heat the olive oil in a Dutch oven or medium heat.
  • Add the sliced leeks, minced garlic, and Thyme, and saute until everything is tender and golden in color.
  • Add the sliced potatoes, chicken stock, butter, salt, and pepper.
  • Bring everything to a boil, then cover, and turn the heat to low or medium/low to maintain a simmer for approximately 20 minutes or until the potatoes are fork tender.
  • Once everything is cooked through and tender, use an immersion blender to puree the soup until it reaches the texture you desire.
  • Add the sour cream and whisk until combined.
  • Add salt and pepper until you reach the flavor you desire.
