Ingredients
- Boneless skinless chicken breasts: cut into chunks provides lean protein that cooks quickly and absorbs all the wonderful curry flavors
- Red curry paste: delivers authentic Thai flavor without hunting for specialty ingredients look for the Maesri or Thai Kitchen brands for best results
- Coconut milk: creates the luxurious creamy base that balances the spicy curry paste use full fat for the richest texture
- Rice noodles: cook right in the broth absorbing flavors while maintaining their delicate texture
- Fresh herbs: cilantro and basil added at the end provide essential brightness and authenticity
- Lime juice: ties everything together with its bright acidity always use fresh squeezed
- Fish sauce: adds that crucial umami depth that makes the soup taste truly Thai
Step-by-Step Instructions
- Sear the Chicken:
- Heat olive oil in a Dutch oven over medium heat until shimmering. Season chicken generously with salt and pepper then add to the hot oil without overcrowding. Let pieces cook undisturbed for about 2 minutes until golden on one side then give a quick stir. The chicken should have beautiful caramelization but still be undercooked inside. Remove to a plate.
- Build the Aromatic Base:
- Add garlic bell pepper and onion to the same pot keeping all those flavorful chicken bits. Cook for a full 3 4 minutes stirring occasionally until onions become translucent and peppers slightly softened. This creates the foundation of flavor for your soup.
- Bloom the Curry Paste:
- Add red curry paste and freshly grated ginger to the vegetables stirring constantly for about one minute. You want to toast the spices until they become intensely fragrant this unlocks their full potential and prevents any raw taste in the finished soup.
- Create the Broth:
- Pour in chicken broth and coconut milk stirring well and scraping the bottom of the pot to release any browned bits. This deglazing step incorporates all those concentrated flavors into your broth. Return the chicken to the pot and bring everything to a gentle boil.
- Simmer and Reduce:
- Reduce heat to maintain a steady simmer allowing the soup to cook uncovered for 10 minutes. During this time the flavors meld the chicken finishes cooking through and the broth slightly reduces becoming more concentrated and flavorful.
- Add Noodles and Seasonings:
- Add rice noodles fish sauce and brown sugar to the simmering broth. Stir occasionally to prevent noodles from sticking together. The noodles will soften and expand as they absorb the flavorful broth becoming perfectly tender in about 5 minutes.
- Finish with Fresh Elements:
- Remove pot from heat then immediately stir in green onions cilantro basil and fresh lime juice. Taste and adjust seasoning with additional salt and pepper as needed. The residual heat will wilt the herbs just enough while preserving their bright flavors.

The red curry paste is truly the heart of this recipe. I once tried to substitute green curry paste thinking it would be similar but the flavor profile completely changed. While still delicious the red curry version has a deeper warmth that pairs perfectly with the coconut milk and lime finish.
Make It Your Own
This recipe welcomes customization based on your preferences and what you have available. Try adding thinly sliced mushrooms or baby bok choy during the last few minutes of cooking for extra vegetables. Shrimp can replace chicken for an equally delicious variation just add them during the last 3 minutes of cooking instead. For vegetarians firm tofu cubes work beautifully in place of chicken.
Storing and Reheating
The soup keeps well in the refrigerator for up to 3 days though I recommend storing the noodles separately if you know you'll have leftovers. The noodles continue absorbing liquid and can become mushy when stored in the broth. To reheat bring the soup to a gentle simmer on the stovetop then add the reserved or fresh noodles just before serving. The soup also freezes well without the noodles for up to 2 months.

Serving Suggestions
Serve this vibrant soup in deep bowls with additional lime wedges on the side. I like to put small dishes of extra toppings on the table so everyone can customize their bowl chopped peanuts bean sprouts extra cilantro and sliced Thai chilies for heat lovers. For a complete meal a simple cucumber salad with rice vinegar dressing makes a refreshing side that complements the richness of the soup.
Adjusting the Heat Level
The spice level of red curry paste varies significantly between brands. For a milder soup start with 2 tablespoons of curry paste then taste and add more if desired. Conversely if you love heat add a sliced Thai chili or two during the simmering stage. Another way to tame the heat is to increase the amount of coconut milk or serve with a dollop of plain yogurt on top which helps cool the palate.
