Ingredients
  

  • 4 bone-in, skin-on chicken thighs about 1.5 to 2 pounds / 700g–900g total
  • 1.5 tsp kosher salt Diamond Crystal preferred
  • 0.5 tsp black pepper
  • 0.5 tsp garlic powder
  • 0.5 tsp onion powder
  • 0.25 tsp smoked paprika
  • Avocado oil or olive oil light spray or 0.5 tbsp to rub

Equipment

  • Air fryer
  • Meat thermometer
  • Wire rack
  • Sheet pan
  • Paper towels

Method
 

  1. Pat the chicken thighs completely dry with paper towels — surface moisture prevents crisping.
  2. Sprinkle 1 teaspoon kosher salt per pound of chicken (roughly 1.5 tsp for this batch). Lift the skin gently and salt underneath if possible.
  3. Place thighs on a wire rack set over a sheet pan and refrigerate uncovered for 8–24 hours. Overnight is ideal — the skin dries to paper-thin while salt penetrates the meat.
  4. Preheat the air fryer to 390°F (200°C) for 3–5 minutes.
  5. Pat the thighs lightly with fresh paper towels. Oil the skin with a light coating using avocado oil spray or a tiny drizzle of olive oil.
  6. Season with pepper, garlic powder, onion powder, and smoked paprika — use a light hand since the salt is already inside the meat.
  7. Arrange thighs skin-side up in the air fryer basket without overlapping. Crowding steams the chicken instead of crisping it.
  8. Air fry at 390°F for 18–22 minutes, depending on size. Check the thickest part with a meat thermometer — target 175–185°F for dark meat.
  9. For maximum crispiness, blast at 400°F for the final 2–3 minutes — this step shatters the skin.
  10. Rest for 5 minutes before serving — the skin continues to crisp as the meat relaxes.

Notes

Per thigh (approximate): 240 calories, 0g net carbs, 16g fat, 22g protein. Dry brining time is the foundation of this recipe — rushing it undermines the entire result. Eight hours shows improvement; overnight (8–24 hours) is when the shattered crispiness truly develops. Dark meat collagen requires 175–185°F internal temperature to render into gelatin; cooking to 165°F (white meat standard) leaves dark meat stringy and tough.
