  • 2 stalks lemongrass (or 1 tablespoon lemongrass paste)
  • 2 tablespoons butter, ghee, or vegan butter (Miyokos is awesome)
  • 2 pounds carrots, scrubbed and chopped into 1" pieces
  • 1 leek, chopped, white and light green parts only
  • 2 cloves garlic, minced
  • 3 cups vegetable or no-chicken broth
  • 15 ounce can coconut milk
  • kosher salt
  • cilantro, minced, for garnish


prepare the lemongrass stalks:

  • Lemongrass is very fibrous and sturdy - you'll need a good knife.
  • Slice off the bulbous ends, about 1" up (discard). At the other end, leafy (or formerly leafy) end, slice off the top, leaving about 4" of stalk from the middle.
  • Peel off the outermost layers, from both the tops and the 4" stalk (discard).
  • Peel off all of the remaining layers from the 4" stalk until you reach the flexible core (reserve).
  • Crush the tops to expose the insides, using something heavy like a meat tenderizer or the pestle of a mortar and pestle.
  • Securely tie the peeled, reserved layers and crushed tops in a bundle with kitchen string.
  • Thinly slice the flexible cores with a sharp knife.

cook the veggies in the pressure cooker:

  • Set an 6 or 8 qt Instant Pot to Saute (medium heat, if adjustable). Add the butter/ghee and let melt.
  • Add the carrots, lemongrass slices, leeks, and a big pinch of salt, and stir well to coat. Let the veggies cook for 10 minutes, stirring frequently. The carrots should be glossy with butter, and the leeks soft.
  • Add the garlic and saute until fragrant.
  • Pour in the broth. Level the carrots so they're below the surface of the broth (if needed, add more broth or water to cover the carrots).
  • Nestle the lemongrass bundle into the broth.
  • Afix the lid, and set the valve control to "Sealing".
  • Choose Manual Pressure for 3 minutes, and let pressurize and cook. When complete, let natural release for 5 minutes, then quick release the remaining pressure.
  • Remove the lid, taking care to watch the drips and steam.
  • Remove and discard the lemongrass bundle.
  • Use an immersion blender to completely smooth out the soup. Taste, and add more salt as needed.
  • Stir in one-and-a-half cups of well-shaken coconut milk and mix until completely combined.*


* Optional: to decorate your soup bowls as in the photos above, first remove and reserve two tablespoons of the thickest part of the coconut milk. Use a small spoon or eyedropper to deposit dots of the milk on top of the soup. Use a thin-bladed paring knife and draw the knife through the soup and the coconut milk dots to create hearts or swirls.
