Ingredients You’ll Need

Soup Base

1 tablespoon coconut oil – Used for sautéing aromatics and adding subtle coconut richness.
3 cloves garlic, minced – Builds a savory foundation for the soup.
1 tablespoon fresh ginger, grated – Adds warmth and brightness characteristic of Thai cuisine.
1 tablespoon red curry paste – Provides concentrated spice, heat, and complexity.

Main Ingredients

1 cup red lentils, rinsed – The protein-rich base that thickens and textures the soup.
2 carrots, diced – Add sweetness, color, and gentle crunch.
3 cups vegetable broth – Forms the liquid base and balances the coconut milk.
1 can (14 oz) coconut milk – Creates creaminess and richness.

Finishing Touches

2 cups fresh spinach – Adds freshness, nutrients, and vibrant green color.
1 lime, juiced – Brightens and balances the richness at the end.
Fresh cilantro – Used as garnish for herbal freshness.
Red chili flakes, to taste – Optional heat adjustment.

Step-by-Step Instructions

Sauté the Aromatics
Heat coconut oil in a large pot over medium heat. Add garlic and ginger, cooking for 1–2 minutes until fragrant, then stir in the red curry paste and cook for another minute to bloom the spices.

Soften the Vegetables and Lentils
Add diced carrots and cook for 3–4 minutes until slightly softened. Stir in the rinsed red lentils, coating them in the aromatic mixture to enhance flavor absorption.

Simmer the Soup
Pour in the vegetable broth and coconut milk, stirring well. Bring to a gentle boil, then reduce heat and simmer for 20–25 minutes, stirring occasionally, until lentils are tender and beginning to break down.

Finish with Greens and Acid
Stir in the spinach and cook for 2–3 minutes until wilted. Remove from heat, add lime juice, and adjust seasoning as needed.

Serve and Garnish
Ladle into bowls and garnish with fresh cilantro and red chili flakes. Serve hot.

Recipe Notes & Tips

Use red lentils only – Green or brown lentils won’t break down enough to achieve the same creamy consistency.
Bloom the curry paste – Cooking it briefly in oil deepens flavor and removes raw spice notes.
Adjust consistency when reheating – Add broth or coconut milk, as the soup thickens over time.
Add lime at the end – Acid added too early dulls brightness; finishing with lime keeps flavors fresh.
Mind curry paste heat – Brands vary widely, so start small and build up.
Stir occasionally while simmering – Prevents lentils from sticking to the bottom.
