Equipment

  • Large pot
  • Cutting board
  • Knife
  • Measuring cups and spoons

Ingredients

  • 1 tablespoon coconut oil 14g
  • 1 small onion, sliced 70g
  • 2 cloves garlic, minced 6g
  • 1 tablespoon ginger, grated 6g
  • 1 stalk lemongrass, pounded and cut into 2-inch pieces 10g
  • 1 pound chicken thighs, boneless and skinless, cut into bite-sized pieces 450g
  • 4 cups chicken broth 960ml
  • 1 can coconut milk, full-fat 14 ounces/400ml
  • 2 tablespoons fish sauce 30ml
  • 1 tablespoon erythritol or preferred keto sweetener 12g
  • ½ teaspoon chili flakes (optional for heat) 1g
  • 1 cup shiitake mushrooms, sliced 150g
  • ½ cup fresh cilantro, chopped 8g
  • 1 lime, juice of 2 tablespoons/30ml
  • Salt to taste
  • Fresh cilantro leaves for garnish

Instructions

  • Heat coconut oil in a large pot over medium heat. Add the sliced onion and sauté until translucent, about 3-4 minutes.
  • Stir in the minced garlic, grated ginger, and lemongrass. Cook for an additional 2 minutes, until aromatic.
  • Add the chicken pieces to the pot and sauté until they are no longer pink on the outside, approximately 5 minutes.
  • Pour in the chicken broth and bring the mixture to a gentle simmer. Let it cook for 10 minutes to allow the flavors to meld.
  • Stir in the full-fat coconut milk, fish sauce, erythritol, and chili flakes (if using). Continue to simmer the soup for another 5 minutes.
  • Add the sliced shiitake mushrooms to the pot and simmer for 5 more minutes, or until the mushrooms are tender.
  • Remove the pot from the heat and discard the lemongrass stalks.
  • Stir in the chopped cilantro and lime juice. Taste and add salt as needed.
  • Serve hot, garnished with fresh cilantro leaves.

Notes

For a spicier soup, add more chili flakes or a small sliced chili pepper while cooking.
If you prefer a soup with more broth, feel free to adjust the amount of chicken broth to your liking.
Lemongrass, ginger, and lime are key to achieving the authentic Tom Kha Gai flavor profile, so don't skip these ingredients.
Ensure that the coconut milk used is full-fat to maintain the keto-friendly high-fat content.
