Whisk together coconut milk, Thai green curry paste, fish sauce, lime juice, brown sugar, garlic, ginger, and lime zest in a large bowl.
Season the chicken breasts or thighs with salt and pepper, then place them in the marinade. Ensure they are well coated.
Cover and refrigerate overnight for at least 1 hour or for better flavor.
Preheat your air fryer to 375°F (190°C).
Remove the chicken from the marinade and place it in the air fryer basket. Avoid overcrowding for even cooking.
Air fry for 10-12 minutes for chicken breasts, for 12-15 minutes for thighs, or until the internal temperature reaches 165°F (74°C). Flip halfway through the cooking time.
While the chicken is cooking, pour the remaining marinade into a saucepan. Bring it to a boil, then reduce the heat and simmer until it thickens slightly, creating a flavorful sauce.
Serve the Thai Coconut Lime Chicken garnished with fresh cilantro and lime slices. Drizzle with the reduced marinade sauce if desired.
This dish pairs well with steamed rice, vegetables, or a fresh salad.
