How to Make Thai Coconut Red Lentil Soup Recipe

Step 1: Sauté Aromatics

Start by heating your choice of vegetable or olive oil in a large pot over medium heat. Toss in the chopped onion and carrot and cook them gently for about 5 minutes until they’re tender and just starting to release their sweetness. This base builds a flavorful foundation that will carry the soup’s taste.

Step 2: Infuse with Spice

Next, stir in the garlic, tomato paste, Thai red curry paste, turmeric, and cayenne pepper. Cook this vibrant mixture for about a minute or until you can smell the fragrant spices blooming. This step wakes up the curry and brings a lovely depth that permeates every spoonful.

Step 3: Simmer the Lentils

Add the red lentils, 1 teaspoon of salt, and the vegetable broth or water to the pot. Bring everything to a gentle simmer, then reduce the heat to medium-low. Partially cover the pot and let the soup cook for around 20 minutes. You’ll notice the lentils swell, soften, and the broth thickens beautifully.

Step 4: Finish with Coconut Milk and Lime

Once the lentils are tender and the soup has thickened nicely, remove the pot from heat and stir in the creamy coconut milk and fresh lime juice. Taste and adjust the seasoning with more salt if needed. This final touch balances creaminess and tang that makes this soup irresistibly comforting.

Step 5: Pressure Cooker Option

If you’re short on time, you can use a pressure cooker. Start by sautéing the onions, carrots, garlic, tomato paste, curry paste, and cayenne pepper using the sauté function. Add the lentils, salt, and broth, then seal and cook on high pressure for 6 minutes. Let the pressure release naturally, then stir in coconut milk and lime juice just like in the stovetop method.

Make Ahead and Storage

Storing Leftovers

This Thai Coconut Red Lentil Soup Recipe keeps wonderfully in the fridge for up to 4 days. Store it in an airtight container to preserve its fresh flavors and creamy texture.

Freezing

To freeze, let the soup cool completely, then transfer it to freezer-safe containers or bags. It freezes well for up to 3 months. Just be sure to leave some headspace for expansion, and thaw overnight in the fridge before reheating.

Reheating

Reheat the soup gently on the stove over low to medium heat, stirring occasionally to prevent the coconut milk from separating. If the soup thickens too much, add a splash of water or broth to bring it back to your desired consistency.

FAQs

Can I use other lentils instead of red lentils?

Red lentils cook quicker and break down easily, creating that creamy texture this soup is known for. Other lentils may take longer and remain firmer, so they will change the soup’s consistency and cooking time.

Is this Thai Coconut Red Lentil Soup Recipe vegan?

Absolutely! Just be sure to check the label on your Thai red curry paste to ensure it doesn’t contain shrimp paste or other animal products. Using vegetable broth keeps it fully plant-based.

How spicy is this soup? Can I adjust the heat?

This soup has a mild to moderate spice level, thanks to the Thai red curry paste and a dash of cayenne. You can easily adjust by using less curry paste or omitting the cayenne pepper if you want it gentler.

What can I substitute if I don’t have coconut milk?

Coconut milk adds creaminess and a subtle sweetness that defines this soup’s flavor. If unavailable, you could use cashew cream or a blend of plant-based milk with a little nut butter, but the flavor profile will be different.

Can I add vegetables or proteins to this soup?

Definitely! Feel free to toss in greens like spinach or kale towards the end of cooking. For protein, precooked chicken, tofu, or shrimp would be excellent additions that complement the flavors nicely.
