Description

Creamy Instant Pot potato leek soup made with tender potatoes, sweet leeks, fresh thyme, and rich cream, served with flavorful goat cheese pea crostini.


Ingredients

  • 3 tablespoons salted butter
  • 3 large leeks, white and light green parts only, thinly sliced and rinsed well
  • 2 celery stalks, chopped
  • 2 teaspoons kosher salt
  • 1/2 teaspoon black pepper, plus more to taste
  • 3 garlic cloves, chopped
  • 6 cups vegetable broth
  • 6 fresh thyme sprigs, plus extra thyme leaves for topping
  • 4 medium russet potatoes, about 2 1/2 pounds, peeled and quartered
  • 1 bay leaf
  • 1 cup heavy cream, plus extra for drizzling
  • 1 cup frozen peas, thawed
  • 4 ounces goat cheese, softened
  • 1 teaspoon grated lemon zest
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon chopped fresh chives
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 12 baguette slices, toasted

Instructions

  1. Set a 6- to 8-quart Instant Pot to sauté on high. Melt the butter completely.
  2. Add the sliced leeks, chopped celery, kosher salt, and black pepper. Cook for 4 to 6 minutes, stirring often, until softened.
  3. Stir in the chopped garlic and cook for about 1 minute until fragrant.
  4. Add the vegetable broth, thyme sprigs, quartered potatoes, and bay leaf. Stir gently to combine.
  5. Lock the lid and set the steam valve to sealing. Cook on high pressure for 10 minutes.
  6. Carefully quick release the pressure using a kitchen towel for protection, then open the lid.
  7. Remove the thyme sprigs and bay leaf. Blend the soup with an immersion blender until smooth.
  8. Stir in the heavy cream and adjust seasoning with additional salt or pepper if needed.
  9. For the crostini, mash the thawed peas in a bowl with a fork.
  10. Add the goat cheese, lemon zest, lemon juice, chives, kosher salt, and black pepper. Mix until creamy but slightly textured.
  11. Spread the pea and goat cheese mixture onto the toasted baguette slices.
  12. Ladle the soup into bowls, drizzle with extra cream, garnish with thyme leaves and black pepper, and serve with the crostini.

Notes

  • Rinse leeks thoroughly after slicing to remove hidden dirt.
  • Blend longer for an extra silky smooth soup texture.
  • For a lighter version, replace part of the cream with milk.
  • Freeze the soup before adding cream for best texture after thawing.
  • Store crostini topping separately from the bread to keep it crisp.
