Spray the air fryer basket with olive oil and set it aside. This prevents the chicken from sticking.
Make sure your chicken is uniformly thick in order for it to cook evenly. I pound my chicken breasts to about 3/4” thick. Use a paper towel to pat the chicken dry.
In a small bowl, mix together the garlic powder, paprika, salt, and if using, the red pepper flakes.
Rub the spice mix over the chicken, ensuring that each piece is evenly coated.
Place the chicken in the air fryer basket in a single layer.
Cook at 375 °F (190 °C) for 10 minutes.
Flip chicken and cook for another 8 minutes.
Once the chicken reaches 165 °F (74 °C) on a meat thermometer, brush the chicken with BBQ sauce and cook for another 2 minutes at 375 °F (190 °C).
Refrigerate leftovers in an airtight container for up to three days.
