Pat the chicken breasts dry with paper towels—this is the single most important step for crispy results. If your breasts are thick (over 1 inch), pound them gently to an even thickness so they cook uniformly.
In a bowl or directly in the Ninja Crispi glass container, whisk together the soy sauce, ginger, garlic, honey, rice vinegar, sesame oil, black pepper, and optional red pepper flakes.
Add the chicken, turn to coat, and let it sit for at least 10 minutes at room temperature or up to overnight in the fridge. Longer marinating equals deeper flavor.
Preheat the Ninja Crispi. Set the Crispi PowerPod to Air Fry at 390°F.
Remove the chicken from the marinade and let any excess drip off—too much liquid steams the chicken instead of crisping it. Brush a light coat of olive oil on each breast for extra browning. Place the chicken in a single layer in the CleanCrisp glass container with at least 1 inch of space between pieces.
Air fry for 9–10 minutes, then carefully flip the chicken using tongs. Continue cooking for another 8–10 minutes, until the internal temperature reaches 165°F at the thickest part. For thinner chicken breasts (under 1 inch), reduce the total cook time to 15–17 minutes.
Pull the chicken out and let it rest for 3–5 minutes before slicing. Slice against the grain, sprinkle with green onions, sesame seeds, and fresh cilantro, and serve.
