Dry the chicken thighs well. In a bowl, combine salt, gochujang, sesame oil, olive oil, brown sugar, baking powder, garlic powder, and black pepper. Coat the chicken thighs thoroughly with the mixture. Preheat air fryer to 380°F (193°C). Place chicken thighs skin-side down in the air fryer and cook for 10 minutes. Flip the chicken thighs and air fry for another 6-10 minutes, or until crispy and golden with an internal temperature of 165°F (74°C).
