- The tender pull on the chicken is unbeatable; it stays juicy and soft.
- Quick release means no need to hang around waitin’ forever.
- The float valve works like a trusty little sentinel keeping everythin’ safe.
- You can sauté right in the pot before pressure cooking, saving dirty dishes.
Everything You Need Lined Up
- 1 tablespoon coconut oil – for that rich start with a hint of tropical vibes.
- Half of one onion, thinly sliced – it melts into sweetness as it cooks.
- 2 cloves garlic, chopped – gives a nice punch and depth to the soup base.
- Half of one red jalapeno, sliced or 1 to 3 Thai chiles, halved – bring the heat as you like it.
- 3 slices of galangal or ginger, about 1/4 inch thick – the zingy root that’s key for that real deal taste.
- 1 lemongrass stalk, pounded and cut into 2-inch pieces – fresh and fragrant to brighten everything up.
- 2 teaspoons red Thai curry paste – packs a spicy, savory kick that’s hard to beat.
- 4 cups chicken broth (or veggie broth for vegan) – the perfect liquid base for rich flavor.
- 4 cups full-fat unsweetened coconut cream or milk – makes the soup creamy and dreamy.
- 2 medium chicken breasts, cut into bite-sized pieces – tender and juicy protein that cooks fast.

How It All Comes Together Step by Step
- Heat the coconut oil in your pressure cooker pot over medium heat. Toss in the sliced onion, chopped garlic, jalapeno or Thai chiles, galangal or ginger, lemongrass pieces, and red curry paste. Stir it around for about 5 minutes till the onions get soft and fragrant.
- Add the 4 cups chicken broth and crank up the heat to bring everything to a boil. Once it’s boiling, let it simmer uncovered for 30 minutes to get all those flavors mingling real good.
- After simmering, strain out all the aromatics – the garlic, onion bits, lemongrass, and ginger slices. You don’t need those floating around anymore, so toss ’em.
- Pour the clear broth back into the pot then stir in the coconut cream or milk and the chicken pieces. Add in those sliced mushrooms too.
- Seal up your pressure cooker with the lid, lock it, and wait for the float valve to pop up as it reaches pressure build. Cook on high pressure for about 5 minutes so the chicken gets that perfect tender pull.
- Once done, do a quick release of the pressure so you’re not waiting too long. Remove the lid carefully.
- Stir in the fish sauce, coconut sugar (or aminos), and fresh lime juice. Taste and adjust to make it salty, sweet, or bright according to your mood.
- Ladle the soup into bowls and sprinkle with sliced green onions and fresh cilantro. Serve hot and enjoy that beautiful balance of creamy, spicy, and fresh flavors.

Smart Shortcuts for Busy Days
- Use frozen lemon grass or ginger to save prep time without losing flavor.
- Buy pre-sliced mushrooms to skip the chopping step.
- Grab canned coconut cream or milk that’s already well mixed to avoid stirring later.
- Prepare the broth base the night before and keep it chilled, so you just heat and cook chicken the next day.
- If you’re short on time, use chicken thighs pre-cut from the store; they cook fast and stay juicy.
When You Finally Get to Eat
You spot that beautiful creamy soup in your bowl. The coconut cream swirls with the red curry hints and the bright green of fresh herbs on top. You gotta appreciate that mix of colors as much as the flavors.
When you take your first sip, you feel that warm spicy wave roll in with a gentle lime kick. The tender chicken bites melt in your mouth with every spoonful, and the mushrooms add that juicy earthiness that makes it all perfect.
You catch yourself wanting just one more spoon, and hey, that’s fine. This soup feels like a big cozy hug on a cold or crazy day, soothing and satisfying like no other.
Making It Last All Week Long
- Fridge: Store in airtight containers for up to 4 days. The flavors actually get better the next day, so no rush to eat it all at once.
- Freezer: Portion leftover soup into freezer-safe bags or containers. It lasts up to 3 months frozen. Just thaw overnight in the fridge and reheat with a gentle simmer so it doesn’t break down.
- Reheat Tips: Warm the soup on the stove over medium-low heat. Stir often to keep coconut cream from separating. Add a splash of broth or water if needed to get back that perfect spoonable consistency.
The FAQ Section You Actually Need
- Can I use tofu instead of chicken? Absolutely! Firm or extra firm tofu cut into cubes works great. Just add it after you strain the broth and simmer till warm.
- What if I can’t find lemongrass? You can use frozen lemongrass or even a little extra lime zest for a bright substitute.
- Is there a vegan version? Sure thing, swap chicken broth for vegetable broth and fish sauce for soy sauce or coconut aminos.
- How spicy is this soup? It depends on how many chilies you toss in. You can go mild with jalapeno or kick it up with Thai chiles. Adjust to your heat comfort.
- Can I make this in an Instant Pot? Yep, just do the sauté and pressure cook steps using the Instant Pot settings. Quick release when done to keep things juicy.
- What’s the secret that makes this soup extra special? It’s the balance of creamy coconut, fresh lime juice to brighten, and fish sauce for savory depth that takes it all to next level. Don’t skip those!
