Prepare the Chicken: Chicken gets seasoned lightly with salt and pepper. Place it directly into the crockpot in a single layer so everything cooks evenly.
Build the Sauce Base: Water, coconut milk, peanut butter, sesame oil, red curry paste, ginger, fish sauce, red pepper flakes, and sriracha go into a bowl. Whisk until smooth and creamy with no lumps.
Combine Everything: Pour the sauce mixture over the chicken. Gently stir so each piece sits fully coated. This helps flavor sink in early.
Slow Cook: Cover the crockpot and cook on low for six to seven hours. The chicken becomes tender and absorbs all the sauce flavors during this time.
Check Texture: Once cooking finishes, gently stir the chicken. The sauce should look thick, glossy, and rich. Taste and adjust salt or spice if needed.
Finish Before Serving: Let the dish rest uncovered for ten minutes. This allows the sauce to thicken slightly more and settle into the chicken.
