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

  • Prep your leeks and peel and chop your potatoes. Discard the top dark green portion of the leeks, retaining the bulbs. Slice the bulbs into rings. Add leeks to a colander and rinse them throughly (use your hands to dislodge any stubborn dirt).
  • Add the butter to the Instant Pot and press the sauté button. Add the onion and sauté, stirring occasionally, for 3-4 minutes. 
  • Add the garlic to the Instant Pot and cook for 30 seconds.
  • 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". Press the "manual" button and set the timer to cook on high pressure for 10 minutes. 
  • Once the countdown has finished, carefully do a quick pressure release (soup can splatter a bit). 
  • 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.

Notes

  • To make this recipe vegetarian, swap the chicken broth for veggie broth. To make it vegan, do that and also swap the butter for 1 tbsp olive oil.
  • Inactive time represents the time it will take to get your Instant Pot up to pressure.
  • I use this 6-quart Instant Pot.
  • Amazon no longer sells the immersion blender I use, but this one has good reviews.
