Let’s break down what makes this soup actually worth making
Where Thai Lentil Soup Comes From
Thai-inspired lentil soups gained popularity in Western kitchens during the 1990s as home cooks started experimenting with curry pastes and coconut milk from Asian grocery stores.
Food Network traces how red curry paste became a pantry staple in American homes, especially after Thai restaurants exploded across major cities. The Instant Pot version takes those bold flavors and makes them weeknight-friendly, cutting down on simmer time while keeping all that depth from the ginger and garlic combination.
What Builds This Thai Lentil Soup Base
The magic in Instant Pot Thai Lentil Soup starts with that coconut oil hitting the sauté function and smelling up the whole kitchen.
✔ Red split lentils : break down fast and create natural creaminess without any dairy
✔ Red curry paste : brings the heat and complexity, find it in the Asian aisle at H-E-B
✔ Canned coconut milk : not the beverage kind, you want the full-fat version in the can
✔ Fresh ginger : cut in half and tossed in whole, easier to fish out later
✔ Cilantro stems : way more flavor than you’d think, save the leaves for garnish
Time to see how this all comes together in the pot.
Making Instant Pot Thai Lentil Soup Step by Step
This whole thing uses the pressure simmer function to get the lentils tender without turning them into mush.
- Turn the Instant Pot to sauté and heat the coconut oil until it shimmers
- Add the onion, carrot, garlic, ginger, and cilantro stems, cook for about 3 minutes
- Stir in the curry paste until it coats everything and smells incredible
- Pour in the lentils, water, bouillon cube, and soy sauce
- Close the lid, seal the valve, and pressure cook on high for 8 minutes
- Quick release the pressure, stir in the coconut milk and spinach
- Add the lime juice, fish out the ginger pieces, and adjust seasoning
The lime juice at the end is what ties everything together, don’t skip it.
Now, if you want to change it up or work with what’s already in your pantry, here’s how.
Ways to Make Instant Pot Thai Lentil Soup Your Own
The base version is solid, but this soup handles variations better than most. I’ve tried a bunch of different tweaks and they all worked surprisingly well.
How to Make Thai Lentil Soup with Green Curry
Swap the red curry paste for green curry paste and add some lemongrass if you can find it. The flavor goes brighter, more herbal. Jake said it tasted like something from that Thai place we hit up downtown, which is high praise coming from him.
Spicy Thai Lentil Soup Recipe Version
Double the curry paste and throw in some fresh Thai chilies if you’re feeling brave. The coconut cream mellows it out enough that it’s not painful, just warm. Sarah made me tone this down after the first time because Sophie couldn’t handle it.
Coconut Thai Lentil Soup Instant Pot with Protein
Toss in some cooked shrimp or shredded chicken during the last few minutes. Turns it from a side soup into a full meal. We do this on Sundays when I’m trying to use up leftover rotisserie chicken from Costco.
Once you’ve got your version dialed in, figure out what you’re putting next to it.
What Goes Well with Thai Lentil Soup
I found out this pairs really well with stuff that’s got some crunch or freshness to balance all that creamy richness.
Jasmine Rice on the Side
The simplest pairing and honestly one of the best. The plain rice soaks up the soup broth and stretches the whole meal further. We make a big batch and keep it in the fridge all week.
Naan Bread for Dipping
Store-bought naan works perfectly here. Toast it quick in a dry skillet and use it to scoop up the lentils. Sophie likes ripping it into pieces and dropping them right in her bowl.
Quick Cucumber Salad
Slice cucumbers thin, toss with rice vinegar and a pinch of sugar. The cool crunch against the warm soup just works. Sarah always makes this when I’m cooking anything with curry paste.
Fried Shallots and Peanut Garnish
This is more of a topping than a side, but it changes everything. The crispy shallots and crushed peanuts add texture that makes each bite more interesting. Buy them pre-made at the Asian market to save time.
Here’s how to keep this soup fresh if you make a big batch.
Keeping Your Instant Pot Thai Lentil Soup Fresh
This soup actually tastes better the next day once all those flavors from the lime zest and fresh basil have had time to really blend together.
Storage
- At room temperature: Don’t leave it out more than 2 hours, the coconut milk can separate weird
- In the fridge: Up to 5 days in airtight containers, keeps the soup broth intact
- In the freezer: Freeze without the coconut cream, add that when reheating for better texture, good for 3 months
Reheating
Microwave in 2-minute intervals, stirring between each one to redistribute the coconut milk evenly. Stovetop works better though, just warm it over medium-low heat and whisk occasionally. Add a splash of water if it’s gotten too thick sitting in the fridge overnight.
Anti-Waste Tip
Blend leftover soup until smooth and use it as a sauce for noodles or rice bowls. Toss in some fresh veggies and protein, suddenly you’ve got a completely different meal that nobody realizes is leftovers.

Questions About Instant Pot Thai Lentil Soup
Making this Thai lentil soup was confusing at first because I wasn’t sure if the lentils would cook through properly under pressure without getting mushy.
Thai flavored Instant Pot lentil soup too thin or watery?
Let it sit uncovered for 5 minutes after cooking. The lentils absorb more liquid as they cool and the soup thickens naturally.
How to make Thai lentil soup less spicy for kids?
Use only 1 tablespoon of curry paste and add extra coconut milk. The green curry paste is milder than red if you swap.
Can I use fish sauce instead of soy sauce?
Yeah, fish sauce actually brings more authentic Thai flavor. Use about half the amount because it’s way saltier than soy.
Easy Thai lentil soup guide for meal prep?
I found that if you portion it into containers right away and don’t add the lime juice until you reheat, the flavors stay brighter all week.

Instructions
- Set your Instant Pot to sauté mode and add the coconut oil.
- Toss in the onion, carrot, garlic, ginger pieces, and cilantro stems, cook for 3 minutes until fragrant.
- Stir in the red curry paste and let it coat everything for about 30 seconds.
- Add the lentils, water, bouillon cube, and soy sauce, stir well.

- At home, we always add extra lime juice right before serving because it brightens everything up and makes the soup taste fresher than it actually is.
