Ingredients

Scale

Soup Base

  • 1 medium onion, diced
  • 1 tablespoon cooking oil
  • 1 smoked sausage link, cubed
  • 2 cups sweet potatoes, peeled or unpeeled, cut into 1/2 inch cubes
  • 3 cloves garlic, minced or 1 teaspoon garlic paste
  • 1 tablespoon ginger, minced or 1 teaspoon ginger paste
  • 2 tablespoons green Thai curry paste
  • 1 cup brown or green lentils, rinsed and picked over
  • 4 cups vegetable or chicken broth

Finishing Ingredients

  • 1 cup full-fat canned coconut milk
  • 2 cups fresh spinach leaves, roughly chopped
  • 1/4 cup fresh cilantro leaves, minced
  • 2 green onions, thinly sliced, for garnish

Instructions

  1. Sauté Aromatics and Sausage: Heat the oil in a large pot over medium heat. Add the diced onions, smoked sausage cubes, and sweet potatoes. Cook, stirring occasionally, until onions have softened and sausage develops golden edges, about 5-7 minutes.
  2. Add Seasonings and Lentils: Stir in the green curry paste, minced ginger, and garlic until fragrant and well combined with the vegetables and sausage. Then add the rinsed lentils and pour in the broth. Stir to combine.
  3. Simmer the Soup: Bring the mixture to a gentle simmer. Partially cover the pot with a lid and cook over low heat for 30-35 minutes, stirring occasionally to prevent sticking, until lentils and sweet potatoes are tender and soup has thickened slightly.
  4. Finish with Coconut Milk and Greens: Stir in the coconut milk, chopped spinach, and minced cilantro. Allow the soup to warm through over low heat for 3-5 minutes until spinach has wilted but remains vibrant.
  5. Serve: Ladle the soup into bowls and garnish with sliced green onions. Serve hot with crusty bread or your preferred side.

Notes

  • Use brown or green lentils for best texture; red lentils will break down into mush.
  • Adjust green curry paste quantity based on your desired spice level and brand heat.
  • Full-fat canned coconut milk delivers the best creamy texture; avoid boxed versions that are thinner and often sweetened.
  • You can omit the smoked sausage to make this vegetarian; consider adding extra vegetables or plant-based protein.
  • This soup stores well in the refrigerator up to 5 days or freezes for up to 3 months.
  • Before cooking lentils, rinse thoroughly and remove any debris.
