Whisk coconut milk, peanut butter, soy sauce, fish sauce, brown sugar, ginger, garlic, turmeric and red pepper flakes in a 5-quart slow cooker until smooth.
Fold in chicken, cover and cook on low for 5 to 6 hours until chicken reaches 165°F and the thigh pieces are tender.
During the final half hour, bring jasmine rice and its measured water to a boil in a saucepan. Cover and cook on low for 15 minutes, then rest off the heat for 10 minutes.
Stir the chicken sauce gently from the bottom, keeping the pieces intact. Switch off the cooker and add lime juice.
Divide rice and peanut chicken among 6 servings and add the chopped peanuts evenly just before eating.
