Why You’ll Love This Recipe

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 tablespoon olive oil or coconut oil
1 small onion, diced
3 cloves garlic, minced
1 tablespoon fresh ginger, grated
1 tablespoon red curry paste
1 cup red lentils, rinsed
4 cups vegetable broth
1 can (13.5 ounces) coconut milk
1 tablespoon soy sauce or tamari
1 teaspoon lime juice
1/2 teaspoon turmeric
salt to taste
black pepper to taste
fresh cilantro for garnish

Directions

1. I heat the oil in a large pot over medium heat. I sauté the diced onion until softened.

2. I add the minced garlic and grated ginger, cooking briefly until fragrant.

3. I stir in the red curry paste and turmeric, letting the spices bloom for about a minute.

4. I add the rinsed red lentils and vegetable broth, bringing everything to a boil.

5. I reduce the heat and let the soup simmer for 20–25 minutes, or until the lentils are soft and beginning to break down.

6. I stir in the coconut milk and soy sauce, letting the soup simmer for another 5 minutes.

7. I add lime juice and adjust the seasoning with salt and pepper.

8. If I want a smoother texture, I blend part of the soup with an immersion blender before serving. I garnish with fresh cilantro.

Servings and Timing

Servings: 4–6

Prep time: 10 minutes
Cook time: 30 minutes
Total time: 40 minutes

Variations

I sometimes add diced carrots or sweet potatoes for extra heartiness. If I want more heat, I stir in a pinch of red pepper flakes or extra curry paste.

For added protein and texture, I top the soup with roasted chickpeas. I also enjoy adding a handful of spinach at the end for more greens.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 4 days. The soup thickens as it sits because the lentils continue to absorb liquid.

To reheat, I warm it gently on the stovetop, adding a splash of broth or water to reach my desired consistency. I can also microwave it in short intervals, stirring in between.

I freeze portions for up to 2 months and thaw them overnight in the refrigerator before reheating.

FAQs

Can I use green or brown lentils instead of red?

I can, but the texture will be different. Red lentils break down and create a creamier soup, while green or brown lentils hold their shape more.

Is this soup spicy?

It has mild warmth from the red curry paste. I adjust the spice level by adding more or less curry paste.

Can I make this soup dairy-free?

Yes, it is naturally dairy-free because the creaminess comes from coconut milk.

Do I need to soak the lentils first?

No, red lentils cook quickly and do not require soaking. I simply rinse them before adding to the pot.

Can I make this in advance?

Yes, I often make it ahead of time. I find the flavors deepen and taste even better the next day.

Conclusion

I find this Simple Thai Coconut Red Lentil Soup to be creamy, flavorful, and incredibly comforting. It is easy to prepare, full of plant-based goodness, and perfect for cozy evenings or meal prep. Whenever I make it, I enjoy how satisfying and nourishing each bowl feels.
