Ingredients

  • 1 tablespoon olive oil
  • 2 tablespoons fresh lemongrass finely chopped
  • 1/2 medium onion chopped
  • 1 teaspoon fresh ginger grated
  • 3-4 cloves garlic minced
  • 3.5 cups vegetable broth or water (see note)
  • 3 heaping tablespoons Thai red curry paste
  • Juice of 1/2 lime + lime wedges for serving
  • 1 medium sweet potato peeled & spiralized on medium setting
  • 1 medium zucchini spiralized on medium setting
  • 1 small celery root (celeriac) peeled & spiralized on medium setting
  • 1 (13.5 ounce) can full fat coconut milk
  • Salt & pepper to taste
  • Handful fresh basil torn 
  • Fresh cilantro chopped, to taste (optional)

Instructions

  • Chop the lemongrass and onion. Spiralize the sweet potato, zucchini, and celery root. 
  • Add the olive oil to a pot on medium-high heat. Sauté the lemongrass, onion, and ginger for 5 minutes, stirring occasionally.
  • Add the garlic and cook for 30 seconds until fragrant.
  • Add the vegetable broth, curry paste, and lime juice. Stir until combined. 
  • Add the spiralized sweet potato, zucchini, and celery root. Cover the pot with the lid slightly ajar and cook for 5 minutes.
  • Stir in the coconut milk and cook for an additional 5 minutes. Season with salt & pepper and add the fresh basil and cilantro (if using). 
  • Serve soup with an extra wedge of lime on the side.

Notes

  • You can do a combination of vegetable broth and water or a stock cube and water if needed. If you're not vegetarian, you could instead use chicken broth. 
  • How to prep the lemongrass: Cut the dry ends off the stalk, then use your hands to peel the tough outer "shell" of the stalk. Discard that outer shell. Use a knife to slice the newly revealed inner stalk. You can then easily chop those slices up finely. 
  • I keep my ginger in the freezer. It's very easy to grate when frozen. I grate it straight into the pan. 
  • I use Thai Kitchen red curry paste in this recipe. It's vegan. Some others contain fish ingredients so just make sure to read the label if that's an issue. 
  • I use the Paderno 4-Blade Spiralizer
