This mouth-watering chicken recipe is bold and spicy, with a touch of nutty flavor! Inspired by the classic Chinese Kou Shui Ji (aka Sichuan Mouthwatering Chicken), I poached tender chicken breasts, then topped them with a fragrant, spicy Sichuan chili sauce. But a few fun twists really make this one my own! Perfect for serving at room temperature or slightly chilled, it’s a dish that’s as beautiful as it is delicious.
Poached Chicken with Sichuan Chili Sauce
My recipe for Sichuan mouthwatering chicken stays true to traditional Kou Shui Ji. The chicken is poached briefly then cooled to maintain juiciness, and the sauce is made by pouring hot oil over aromatics to release their fragrance. But I change things up by incorporating roasted peanuts for extra crunch and nuttiness, Korean chili flakes (gochugaru) and paprika for a fruity heat, and a touch of black vinegar for balanced acidity. The result is a vibrant, nutty, and aromatic chili oil sauce that clings beautifully to each slice of chicken breast!

Chill Before Slicing
After poaching, place the chicken in an ice bath until completely cool, then refrigerate for 15-20 minutes before slicing. This firms up the meat, making clean, even slices that hold together beautifully under the Sichuan chili sauce. It also prevents the sauce from soaking in too quickly, so every bite stays perfectly coated without getting soggy.
🙈 Learn from my mistake!
I didn’t add water the first time I tested this chili oil sauce because I didn’t want to dilute the flavor. But that left me with a too-hot and too-thick mixture that clumped up when I poured it over the chilled chicken.
💡Lesson Learned: Adding water at the end cools the mixture and loosens it up, so it coats the chicken perfectly. I just increased some of the other ingredients to make sure the flavor shines through!

- Add the chicken, let it boil for 1 minute, then reduce the heat to low, cover, and simmer for 20 minutes.2 boneless, skinless chicken breasts
Make the Sauce:
- While the chicken cooks, prepare the sauce. Combine the peanuts, gochugaru, paprika, sesame seeds, sugar, 1 teaspoon salt, and the rest of the scallion whites in a heat-proof bowl.3 tablespoons crushed roasted peanuts, 2 tablespoons gochugaru, 1 teaspoon ground paprika, 1 tablespoon toasted sesame seeds, 1 teaspoon granulated sugar, 1 teaspoon table salt
- Heat the vegetable oil in a small pan over medium heat until hot but not smoking. Add the grated ginger and Sichuan peppercorns and cook for 1-2 minutes, until fragrant.⅓ cup vegetable oil, 1 teaspoon grated fresh ginger, 1 teaspoon Sichuan peppercorns
- Strain out the solids, then pour the hot oil over the ingredients in the bowl.
- Stir in the 3 tablespoons water and the black vinegar until evenly mixed. Set aside.3 tablespoons water, 1 teaspoon black vinegar
Finish and Serve:
- Prepare an ice bath by filling a bowl ⅔ with cool water, and adding enough ice to bring the water line to ¾. When the chicken reaches 165°F, transfer it to the ice bath to cool completely, about 15-20 minutes.
- Slice into bite-sized pieces and arrange on a serving plate.
- Spoon the chili oil sauce over the chicken and garnish with the reserved scallion greens and extra sesame seeds. Serve at room temperature or slightly chilled.
Notes
- A pot with tall sides maintains a consistent simmer for even poaching; if using a wide shallow pan, add a bit more water to ensure the chicken stays submerged.
- Adding ginger and scallion whites at the start infuses the liquid as it heats, creating a subtle broth that seasons the chicken throughout.
- Pouring hot oil over the chili mixture intensifies color, aroma, and flavor; it essentially “opens up” the spices for maximum impact.
- If you prefer a milder sauce, let the oil cool for 30 seconds before pouring; hotter oil produces a deeper, stronger heat.
- Adding water and vinegar at the end cools the mixture and loosens the texture so it coats the chicken instead of clumping.
- If you don’t have a thermometer, check the chicken for doneness by slicing into the thickest part to confirm no pink remains.
- Rapidly cooling the chicken in an ice bath keeps it juicy and prevents overcooking; if you’re out of ice, transfer it to a chilled plate and refrigerate uncovered for 10-15 minutes.
- If you struggle to get clean slices, refrigerate the chicken for 20 minutes after cooling; firmer meat slices more evenly.
- This dish shines when served at room temperature or slightly chilled because the sauce coats each piece cleanly without melting.
- Use leftover chicken in cold noodle bowls, lettuce cups, rice bowls, or tucked into a wrap with crisp vegetables and herbs.

Unique Ingredients and Substitutions
Some of the ingredients in this Sichuan-style mouth watering chicken might be new to you, but each one plays a key role in flavor and authenticity. Here’s where to find them–and what you can substitute.
- Gochugaru (Korean Chili Flakes): Adds bright, fruity heat that blooms beautifully under hot oil, giving the sauce depth without overpowering spiciness. Find it at Asian grocery stores or online. Substitute with Aleppo pepper or a mild chili powder.
- Sichuan Peppercorns: These give the signature “numbing” tingle and a floral, citrusy aroma that elevates the chili oil. Available at Chinese grocery stores or online. For a mild substitute, use cracked black pepper with a pinch of coriander.
- Black Vinegar (Chinkiang Vinegar): Provides earthy acidity and subtle sweetness that balances the richness of the sauce. Available at Asian markets or online. Use rice vinegar or sherry vinegar in a slightly reduced amount if needed.
How to Make Mouth-watering Chicken Step by Step
Prep: Gather the list of ingredients for this easy Kou Shui Ji recipe. To prepare for poaching the chicken, slice the ginger; thinly slice 5 scallions, and divide them into white and green parts; then, divide the white and green parts in half. To prepare to make the chili sauce, crush the roasted peanuts and grate the ginger.
Boil the Water: Bring 4 cups of water, 1 (1-inch piece) of fresh sliced ginger, half of the scallion whites, and 1 teaspoon of table salt to a boil in a medium pot.
Poach the Chicken: Add 2 boneless, skinless chicken breasts, let them boil for 1 minute, then reduce the heat to low, cover, and simmer for 20 minutes, or until cooked through to 165°F.
Prep the Sauce: While the chicken cooks, combine 3 tablespoons of crushed roasted peanuts, 2 tablespoons of gochugaru, 1 teaspoon of ground paprika, 1 tablespoon of toasted sesame seeds, 1 teaspoon of granulated sugar, 1 teaspoon of table salt, and the rest of the scallion whites in a heat-proof bowl.
Flavor the Oil: Heat ⅓ cup of vegetable oil in a small pan set over medium heat until hot but not smoking. Add 1 teaspoon of grated fresh ginger and 1 teaspoon of Sichuan peppercorns and cook for 1-2 minutes, until fragrant.
Strain the Oil: Strain out the solids, then pour the hot oil over the ingredients in the bowl. For a milder sauce, let the oil cool for 30 seconds before pouring.
Season the Sauce: Stir in 3 tablespoons of water and 1 teaspoon of black vinegar until evenly mixed. This helps loosen and emulsify the sauce so it coats the chicken evenly. Set aside.
Chill the Chicken: Prepare an ice bath by filling a bowl ⅔ with cool water, and adding enough ice to bring the water line to ¾. When the chicken has cooked through, transfer it to an ice bath to cool completely, about 15-20 minutes.
Slice the Chicken: Slice the cooled chicken breasts and arrange on a serving plate. If you find the chicken difficult to slice, chill it in the refrigerator for an additional 20 minutes to make it easier to slice.
Sauce and Serve: Spoon the chili oil sauce over the poached chicken and garnish with the reserved scallion greens and extra sesame seeds. Serve mouthwatering chicken cold, at room temperature, or slightly chilled for the best flavor. It pairs well with chilled noodles, steamed rice, cucumber salad, or sautéed greens!
How to Store, Freeze, and Reheat
Store leftover poached chicken and chili oil sauce in separate airtight containers in the refrigerator for up to 3 days (the sauce can go for up to 1 week). You can also freeze the chicken for up to 3 months. Let thaw overnight in the refrigerator before enjoying. Allow the chicken to sit out at room temperature for 15 minutes before spooning over sauce and serving.
