While the oven preheats, combine the mayonnaise, sweet chili sauce, sriracha, honey, and garlic powder in a bowl and whisk until smooth and fully incorporated. The honey dissolves into the sauce and adds a subtle sweetness that balances the heat from the sriracha—this is essential for the signature bang bang flavor. Set the sauce aside until the nuggets are ready.
Preheat your air fryer to 300°F (193°C) or a conventional oven to 400°F. Arrange the frozen chicken nuggets in a single layer on the air fryer basket or baking sheet and cook for 10 minutes in the air fryer or 12 minutes in the oven, until golden and crispy. I prefer the air fryer here because it gives you that perfect crunch without needing oil, plus the shorter cooking time means your sauce stays fresh and vibrant.
Transfer the hot nuggets directly from the fryer or oven to a large bowl and immediately pour the bang bang sauce from Step 1 over them. Toss gently but thoroughly to coat every nugget evenly—the heat from the nuggets will help the sauce cling better. Add the sliced green onions and toss once more to distribute them throughout. Serve immediately while the nuggets are still crispy and warm.
