1Preheat the air fryer to 188°C (370°F).
2Remove the chicken breast from packaging and set aside.
3In a small bowl, mix brown sugar, paprika, garlic powder, oregano, salt, and red pepper flakes.
4Brush the chicken breast with oil on both sides, then sprinkle the spice mixture evenly over it.
5Place the chicken breast in the air fryer basket and cook for 25-30 minutes, turning it when about 10 minutes remain.
6Cook until the thickest part of the meat reaches an internal temperature of 74°C (165°F). If the breast is larger, add a few more minutes.
7Remove from the air fryer and serve immediately.
