Preheat your air fryer to 400°F (204°C) for 5 minutes.
While your air fryer is preheating, create the dry rub seasoning. Mix the garlic powder, onion powder, paprika, salt, and black pepper in a small bowl.
Drizzle and massage the frozen boneless chicken thighs with avocado oil, ensuring they’re evenly coated.
Sprinkle the spice mixture evenly over both sides of the chicken thighs.
Once preheated, place the seasoned frozen chicken thighs in the air fryer basket in a single layer, skin side down.
Cook the chicken thighs in the air fryer at 400°F (204°C) for 15-20 minutes, flipping them halfway through. Add 2 - 4 minutes for extra crispness.
To ensure the chicken thighs are thoroughly cooked, use a meat thermometer to check the internal temperature, which should reach 165°F (74°C).
Once cooked, remove the air fried frozen chicken thighs. Let them rest for 5 - 10 minutes before serving.
Serve and enjoy!
