Prep the chicken: Pat the thighs dry with paper towels. Dry skin equals crisp skin.
Season simply: In a bowl, toss thighs with salt, pepper, garlic powder, smoked paprika, and oil until evenly coated.
Preheat the air fryer: Set to 380°F (193°C) for 5 minutes.
Lightly spray the basket to prevent sticking.
Air fry the first round: Arrange thighs skin-side down in a single layer. Cook at 380°F for 12 minutes.
Flip for crisp skin: Turn skin-side up and cook another 10–12 minutes, until the skin is crisp and the internal temperature hits 165°F.
Make the glaze: While the chicken cooks, whisk Sriracha, honey, soy sauce, rice vinegar, ginger, garlic, and sesame oil in a small saucepan over medium heat. Simmer for 2–3 minutes.
If you want it thicker, stir in the cornstarch slurry and simmer 1 more minute.
Glaze and finish: Brush the cooked thighs generously with the honey Sriracha glaze. Air fry 2–3 more minutes at 380°F to set the glaze and caramelize slightly.
Rest and garnish: Let the chicken rest 5 minutes. Top with green onions and sesame seeds.
Serve with lime wedges and your favorite sides.
