Soak the skewers: If using bamboo skewers, submerge them in water for 20–30 minutes to prevent burning.
Mix the marinade: In a bowl, whisk 1/2 cup coconut milk, 2 tablespoons soy sauce, 1 tablespoon brown sugar, 2 cloves minced garlic, 1 tablespoon grated ginger, 1 teaspoon curry powder, 1/2 teaspoon ground coriander, 1 teaspoon lime juice, 1 tablespoon neutral oil, a pinch of salt and pepper, and chili flakes if you like heat.
Marinate the chicken: Add chicken strips to the marinade and toss to coat.
Cover and chill at least 30 minutes, preferably 2–4 hours for deeper flavor.
Preheat the air fryer: Set to 375°F (190°C). Lightly oil the basket or use a perforated parchment liner designed for air fryers.
Thread the skewers: Pierce chicken strips onto skewers in a gentle weave so they lie flat. Shake off excess marinade to minimize dripping.
Air fry in batches: Arrange skewers in a single layer with space between.
Cook 8–10 minutes, flipping halfway, until the edges are browned and the internal temperature reaches 165°F (74°C).
Make the peanut sauce: While the chicken cooks, whisk 1/3 cup peanut butter, 1 tablespoon soy sauce, 1 tablespoon lime juice, 1 tablespoon brown sugar, 1 small clove minced garlic, 1 teaspoon grated ginger, and 2–4 tablespoons coconut milk or warm water until smooth. Adjust thickness and seasoning to taste.
Finish and serve: Rest skewers for 2–3 minutes. Garnish with chopped peanuts and cilantro.
Serve with peanut sauce, lime wedges, and cucumbers over rice or noodles.
