01 - Preheat oven to 400°F or heat air fryer to 375°F. Line a baking sheet with parchment paper or spray air fryer basket with nonstick spray.
02 - In a bowl, toss chicken pieces with salt, black pepper, and garlic powder until evenly coated.
03 - Mix almond flour and parmesan cheese in a shallow dish until well combined.
04 - Dredge each chicken piece in the flour mixture, pressing lightly to adhere the coating evenly.
05 - Arrange coated chicken on the prepared baking sheet or in air fryer basket. Bake for 15–18 minutes or air fry for 12–15 minutes, turning halfway, until golden brown and cooked through.
06 - While chicken cooks, whisk together mayonnaise, sriracha, rice vinegar, sweetener, and sesame oil in a bowl until smooth and fully combined.
07 - Once chicken is cooked, transfer immediately to the bowl with sauce. Toss gently to coat each piece evenly.
08 - Transfer to a serving platter. Garnish with chopped scallions and toasted sesame seeds. Serve hot.
