Ingredients

  • 3-4 medium-to-large leeks (use the white parts) sliced
  • 4 large Russet potatoes peeled & diced
  • 2 tablespoons butter
  • 1/2 medium onion chopped
  • 1 large clove garlic minced
  • 4 cups chicken broth or stock (or use veg broth)
  • 1 cup water
  • 1/4 teaspoon dried thyme
  • Salt & pepper to taste
  • Fresh chives chopped (optional, for garnish)

Instructions

  1. Prep your leeks and peel and chop your potatoes. Be sure to wash the leeks thoroughly - dirt tends to hide. Here's a handy guide on how to clean leeks.

  2. Add the butter to the Instant Pot and press the sauté button. Add the onion and sauté, stirring occasionally, for 3-4 minutes. 

  3. Add the garlic to the Instant Pot and cook for 30 seconds.

  4. Add the broth, water, leeks, potatoes, and thyme to the Instant Pot. Give it a stir and then close the lid and set the valve on "sealing". Cook on high pressure for 10 minutes. 

  5. Once the countdown has finished, carefully do a quick pressure release. 

  6. Using an immersion blender, puree the soup until smooth. You could also blend it in batches using a regular blender (I suggest letting the soup cool a bit first). Season soup with salt & pepper as needed. Garnish with chives if desired.
