I’m sharing my slow cooker Thai Coconut Chicken Soup recipe that combines coconut milk, shredded chicken, red curry paste and mushrooms, finished with fresh cilantro and lime wedges.

Jump to Recipe

I wasn’t planning to write about this Thai Coconut Chicken Soup, but every time I make it people ask how it happens. The coconut milk turns the soup into something silky, while a spoon of red curry paste gives it a little kick that makes you sit up and pay attention.

I fiddled with it enough times that some nights it came out brighter, other nights deeper, but it always left everyone guessing what the secret was. It’s simple, not showy, and somehow keeps pulling you back for another bowl, like it knows one more bite will reveal something new.

How to Make this

1. In a small skillet heat 1 tablespoon neutral oil over medium heat, add the minced garlic, grated ginger and the red curry paste and cook 30–60 seconds until fragrant to wake up the spices, then scrape everything into the Crockpot.

2. Add the shredded cooked chicken, chicken broth, sliced mushrooms, brown sugar and fish sauce to the Crockpot and stir to combine.

3. Cover and cook on low for
1.5 to 2 hours or on high for 30 to 45 minutes, until the mushrooms are tender and the flavors have melded. (If you were using raw chicken you would do 3 to 4 hours on low.)

4. About 25 to 30 minutes before you plan to serve stir in the coconut milk and the fresh lime juice so the coconut milk warms through without separating.

5. Taste and adjust seasonings: add more fish sauce if it needs salt, more lime juice if it needs brightness, or a pinch more brown sugar if it needs balancing. Don’t overdo the fish sauce, it’s salty.

6. If the soup seems too thin, uncover and cook another 10–15 minutes to reduce slightly, or whisk a teaspoon of cornstarch with cold water and stir in to thicken, cook 5 more minutes.

7. When ready, give the soup one last stir, shred any big chicken pieces if needed, and ladle into bowls.

8. Garnish each bowl with plenty of fresh cilantro leaves and lime wedges on the side so people can squeeze to taste.

9. Serve hot, with rice or rice noodles if you want something more filling. Enjoy, and remember to taste as you go so it ends up perfectly balanced.

Equipment Needed

1. Crockpot or slow cooker (4 to 6 quart)
2. Small skillet to wake up the curry paste and aromatics
3. Wooden spoon or heatproof spatula for stirring
4. Chef’s knife and cutting board for slicing mushrooms and shredding chicken
5. Measuring cups and measuring spoons
6. Microplane or fine grater for the ginger
7. Small bowl and whisk or fork for a cornstarch slurry if you need to thicken
8. Ladle and bowls for serving, plus a pair of tongs or forks to shred any big chicken pieces

FAQ

Q: Can I use raw chicken instead of shredded cooked chicken?

A: Yes. Poach chicken breasts or thighs in the broth for about 12 to 18 minutes until the thickest part reads 165 F, shred with two forks and return to the soup to finish simmering, simple and easy to do.

Q: How do I make the soup less or more spicy?

A: Cut the red curry paste to half for a milder bowl, add more by teaspoons to crank it up, and remember coconut milk tames heat so add extra if it gets too hot, you can also finish with a drizzle of sriracha if you want more kick.

Q: Can I make this vegetarian or vegan?

A: Absolutely, swap chicken for firm tofu or extra mushrooms, use vegetable broth and replace fish sauce with tamari or a vegan fish sauce made from seaweed, keep the lime and cilantro for the bright finish.

Q: Will light coconut milk work or should I use full fat or coconut cream?

A: Light coconut milk works fine but the soup will be less rich, full fat or a splash of coconut cream makes it silkier and more restaurant like, so choose based on how indulgent you want it.

Q: How should I store and reheat leftovers?

A: Store in an airtight container in the fridge up to four days or freeze up to three months, coconut milk may separate when chilled so reheat gently over low heat and whisk to recombine, add fresh lime juice and cilantro after reheating.

Q: Can I add noodles or rice to make it heartier?

A: Yes, add cooked rice or rice noodles at the end, keep them separate until serving if you want them to stay firm otherwise they soak up the broth and get soft, simple trick for leftovers too.

Thai Coconut Chicken Soup Recipe Substitutions and Variations

Shredded cooked chicken: swap for shredded rotisserie turkey, cooked shrimp, or firm tofu (press out water and cube) — oops can’t use that mark. Use comma instead: shredded rotisserie turkey, cooked shrimp, or firm tofu (press out water and cube).
Low sodium chicken broth: use vegetable broth, water plus 1 bouillon cube, or mushroom broth for more umami.
Coconut milk: use light coconut milk, coconut cream thinned with water (1 part cream to 1 part water), or 1 cup dairy milk plus 1/4 cup canned coconut for a milder coconut flavor.
Fish sauce: use soy sauce or tamari for a veg-friendly swap, miso paste diluted with warm water, or a little Worcestershire sauce if you have no other option.

Pro Tips

– Bloom the curry paste a tad longer than you might think and deglaze the pan with a splash of broth before it goes in the slow cooker. It brings out deeper, toasted flavors. Just dont let it burn, or it will turn bitter.

– Don’t dump the mushrooms straight into the pot raw if you can help it. Salt them, let them sit a few minutes, then brown them in a hot pan to concentrate flavor and drive off excess water. That way the soup won’t go thin or mealy.

– Add the coconut milk at the very end and warm it gently. If it simmers hard the fat can separate and look grainy. For a richer, silkier finish use some coconut cream or one can full fat coconut milk instead of the light stuff.

– Season in small steps. Fish sauce is powerful so add little by little, taste, then add more. If you overshoot on salt, dilute with a bit more broth or coconut milk, or toss in a peeled potato to absorb extra salt while it simmers then remove it.

– For extra aroma and authenticity, toss in a couple bruised kaffir lime leaves or a smashed stalk of lemongrass at the start and fish them out before serving. Finish with lots of lime and fresh herbs, and if you like heat add sliced chilies or a drizzle of chili oil.
