Whisk coconut milk, soy sauce, lime juice, brown sugar, garlic, ginger, and red pepper flakes in a bowl until smooth, about 2 minutes. Pour the sauce mixture into the crockpot.
1 can coconut milk, 3 tbsp soy sauce, 2 tbsp lime juice, 2 tbsp brown sugar, 4 cloves garlic, 1 tbsp fresh ginger, ¼ tsp red pepper flakes
Add chicken thighs to the crockpot, turning once to coat both sides with the sauce. Pieces can stack without overlapping. Optionally sear thighs before adding for deeper flavor.
2 lbs chicken thighs
Cover and cook on low heat for 5 to 6 hours or on high heat for 3 to 4 hours. Check the internal temperature toward the lower end of cooking time; chicken is done at 165°F (74°C).
About 30 minutes before serving, stir the peanut butter into the sauce in the crockpot until fully incorporated. The sauce will thicken as it stands. Optionally shred chicken with two forks or leave whole.
½ cup peanut butter
Taste the sauce and adjust with additional lime juice, soy sauce, or red pepper flakes if needed. Garnish with chopped cilantro, crushed peanuts, and lime wedges. Serve over jasmine rice or rice noodles.
